DETAILED DESCRIPTION [0056] One or more modalities are now described with reference to the drawings, in which the same reference numbers are used to refer to the same elements throughout the document. In the following description, for the purpose of explanation, numerous details are presented to provide a complete understanding of the various modalities. However, it is
evident that the various modalities can be practiced without these details (and without application in any standard or environment networked particular). [0057] In a modality, is displayed one system in
guided wave communication for sending and receiving communication signals, such as data or other signaling via guided electromagnetic waves. Guided electromagnetic waves include, for example, surface waves or other electromagnetic waves that are connected to, or guided by, a transmission medium. It will be recognized that a variety of means of transmission can be used with guided wave communications without departing from the example modalities. Examples of such means of transmission may include one or more of the following, either alone or in one or more combinations: yarns, isolated or not, and monofilament or multifilament; conductors or other shapes or other configurations including wire bundles, cables, rods, rails, tubes; non-conductive, such as tubes, rods, dielectric gutters or other
Petition 870190094101, of 9/19/2019, p. 16/263
10/206 dielectric members; combinations of conductors and dielectric materials; or other means of guided wave transmission. [0058] The induction of guided electromagnetic waves in a transmission medium can be independent of any current, charge or electrical potential that is injected or transmitted through the transmission medium as part of an electrical circuit. For example, in the case where the transmission medium is a wire, it has to be recognized that although a small current in the wire may be formed in response to the propagation of the guided waves along the wire, this may be due to the propagation of the electromagnetic wave. along the surface of the wire, and is not formed in response to the current, charge, or electrical potential that is injected into the wire as part of an electrical circuit. Consequently, electromagnetic waves moving on the wire do not require a circuit to propagate along the surface of the wire. The wire is thus a single wire transmission line that is not part of a circuit. Likewise, in some embodiments, a wire is not necessary, and electromagnetic waves can propagate over a single-line transmission medium other than a wire.
[0059] More generally, guided electromagnetic waves or guided waves as described in the present disclosure are affected by the presence of a physical object that constitutes at least part of the transmission medium (for example, a bare wire or other conductor, a dielectric , an insulated wire, a conduit or other hollow element, a bundle of insulated wires that is covered, protected or surrounded by a dielectric or insulator or other bundle of wires, or otherwise
Petition 870190094101, of 9/19/2019, p. 17/263
11/206 of solid, liquid or otherwise non-gaseous transmission medium) to be at least partially linked to, or guided by, the physical object and in order to propagate along a transmission path of the physical object. This physical object can operate as at least a part of a transmission medium that guides, through an interface of the transmission medium (for example, an outer surface, inner surface, an inner portion between the outer and inner surfaces or another boundary between elements of the transmission medium), the propagation of guided electromagnetic waves which, in turn, can carry energy, data and / or other signals along the transmission path from a sending device to a receiving device.
[0060] Contrary to the free space propagation of wireless signals, such as, for example, unguided (or unconnected) electromagnetic waves that decrease in intensity inversely by the square of the distance traveled by the unguided electromagnetic waves, the guided electromagnetic waves can be propagate over a transmission medium with less loss in magnitude per unit distance compared to that experienced by unguided electromagnetic waves.
[0061] Contrary to electrical signals, guided electromagnetic waves can propagate from a sending device to a receiving device without requiring a separate electrical return path between the sending device and the receiving device. As a consequence, guided electromagnetic waves can
Petition 870190094101, of 9/19/2019, p. 18/263
12/206 propagate from a sending device to a receiving device along a transmission medium having no conductive components (for example, a dielectric strip) or via a transmission medium having no more than a single conductor (for example, a single bare wire or insulated wire). Even if a transmission medium includes one or more conductive components and the guided electromagnetic waves propagating along the transmission medium generate currents that circulate in one or more conductive components in the direction of the guided electromagnetic waves, these guided electromagnetic waves can propagate along the transmission medium from a sending device to a receiving device without requiring a flow of opposite currents in an electrical return path between the sending device and the receiving device.
[0062] In a non-limiting illustration, electrical systems that transmit and receive electrical signals between sending and receiving devices through conduction means are considered. These systems generally depend on electrically separate forward and return paths. For example, it is considered a coaxial cable having a central conductor and an earthed shield that are separated by an insulator. Typically, in an electrical system, a first terminal of a sending (or receiving) device can be connected to the central conductor, and a second terminal of a sending (or receiving) device can be connected to the grounded shield. If the sending device injects an electrical signal into the central conductor via the first
Petition 870190094101, of 9/19/2019, p. 19/263
13/206 terminal, the electrical signal will propagate along the central conductor causing direct currents in the central conductor and return currents in the grounded shield. The same conditions apply to a two-terminal receiving device.
[0063] In contrast, it is considered a guided wave communication system, as described in the disclosure under discussion, which can use different modalities of a transmission medium (including, among others, a coaxial cable) for the transmission and reception of waves guided electromagnetic waves without an electrical return path. In one embodiment, for example, the guided wave communication system of the disclosure under discussion can be configured to induce guided electromagnetic waves that propagate along an outer surface of a coaxial cable. Although guided electromagnetic waves cause direct currents in the grounded shield, guided electromagnetic waves do not require return currents to allow the propagation of guided electromagnetic waves along the outer surface of the coaxial cable. The same can be said of other means of transmission used by a guided wave communication system for the transmission and reception of guided electromagnetic waves. For example, guided electromagnetic waves induced by the guided wave communication system on an outer surface of a bare wire, or an insulated wire, can propagate along the bare wire or the bare bare wire without an electrical return path.
Petition 870190094101, of 9/19/2019, p. 20/263
14/206 [0064] Consequently, electrical systems that require two or more conductors to carry direct and reverse currents on separate conductors to allow the propagation of electrical signals injected by a sending device are distinct from guided wave systems that induce electromagnetic waves guided on a transmission medium interface without the need for an electrical return path to allow the propagation of guided electromagnetic waves along the transmission medium interface.
[0065] It is further noted that guided electromagnetic waves, as described in the disclosure under discussion, may have an electromagnetic field structure that is essentially or substantially outside a transmission medium, in order to be connected to, or guided by, means of transmission and in order to propagate non-trivial distances on, or along, an outer surface of the means of transmission. In other embodiments, the guided electromagnetic waves may have an electromagnetic field structure that is essentially or substantially within a transmission medium, in order to be connected to, or guided by, the transmission medium and in order to propagate distances not within the transmission medium. In other embodiments, the guided electromagnetic waves may have an electromagnetic field structure that is partly inside and partly outside a transmission medium, in order to be connected to, or guided by, the transmission medium and in order to propagate non-trivial distances along the transmission medium. The desired electronic field structure
Petition 870190094101, of 9/19/2019, p. 21/263
15/206 in a modality can vary based on a variety of factors, including the desired transmission distance, the characteristics of the transmission medium itself and the environmental conditions / characteristics outside the transmission medium (for example, presence of rain, fog) , atmospheric conditions, etc.).
[0066] Several modalities described in this document relate to coupling devices, which can be referred to as waveguide coupling devices, waveguide couplers or more simply as couplers, coupling devices or launchers for launching and / or extracting guided electromagnetic waves from and to a transmission medium at millimeter wave frequencies (for example, 30 to 300 GHz), where the wavelength may be short compared to one or more dimensions of the coupling device and / or the transmission medium, such as the circumference of a wire or other cross-sectional dimension, or lower microwave frequencies, such as, for example, 300 MHz to 30 GHz. Transmissions can be generated to propagate as waves guided by a coupling device, such as: a ribbon, a bow or other length of dielectric material; a horn, monopole, rod, groove or other antenna; an array of antennas; a magnetic resonant cavity or other resonant coupler; a coil, a ribbon line, a waveguide or other coupling device. In operation, the coupling device receives an electromagnetic wave from a transmitter or transmission medium. THE
Petition 870190094101, of 9/19/2019, p. 22/263
16/206 electromagnetic field structure of the electromagnetic wave can be transported inside the coupling device, outside the coupling device or some combination thereof. When the coupling device is close to a transmission medium, at least a portion of an electromagnetic wave is coupled to, or connected to, the transmission medium, and continues to propagate as guided electromagnetic waves. Conversely, a coupling device can extract guided waves from a transmission medium and transfer these electromagnetic waves to a receiver.
[0067] According to an example modality, a surface wave is a type of guided wave that is guided by a surface of a transmission medium, such as, for example, an outer or outer surface of the wire, or another surface of the wire that is adjacent to or exposed to another type of medium having different properties (for example, dielectric properties). In fact, in an example embodiment, a surface of the wire that guides a surface wave can represent a transitional surface between two different types of media. For example, in the case of a bare or uninsulated wire, the surface of the wire may be the outer or outer conductive surface of the bare or uninsulated wire that is exposed to air or free space. As another example, in the case of insulated wire, the surface of the wire may be the conductive portion of the wire that intersects with the insulating portion of the wire, or it may be the insulating surface of the wire that is exposed to air or free space or can then be any region of material between the insulating surface
Petition 870190094101, of 9/19/2019, p. 23/263
17/206 of the wire and the conductive portion of the wire that intersects with the insulating portion of the wire, depending on the relative differences in the properties (for example, dielectric properties) of the insulator, air, and / or the conductor and also dependent on the frequency and of the guided wave propagation mode or modes.
[00 68] According to an example embodiment, the term around a wire or other transmission medium used in conjunction with a guided wave may include fundamental guided wave propagation modes, such as, for example, a guided wave having a circular or substantially circular field distribution, a symmetrical electromagnetic field distribution (for example, electric field, magnetic field, electromagnetic field, etc.) or another pattern in a fundamental way, at least partially around a wire or other medium transmission. In addition, when a guided wave propagates around a wire or other transmission medium, it can do so according to a guided wave propagation mode that includes not only the fundamental wave propagation modes (for example , zero-order modes) as well as additional or alternatively non-fundamental wave propagation modes, such as higher-order guided wave modes (eg, 1st ^- order modes, 2nd ^- order modes, etc.) , asymmetric modes and / or other guided waves (for example, surface) that have non-circular field distributions around a wire or other transmission medium. As used herein, the term guided wave mode refers to a mode of guided wave propagation of a transmission medium,
Petition 870190094101, of 9/19/2019, p. 24/263
18/206 coupling device or other system component of a guided wave communication system.
[0069] For example, these non-circular field distributions can be unilateral or multilateral with one or more axial shoulders characterized by relatively higher field strength and / or one or more zeroes or null regions characterized by relatively low field strength, force zero field strength or substantially zero field strength. In addition, the field distribution can then vary as a function of an azimuthal orientation around the wire so that one or more angular regions around the wire have an electric or magnetic field strength (or combination thereof) that is greater than one or more other angular regions of azimuth orientation, according to an example embodiment. It will be recognized that the relative orientations or positions of the higher order modes or asymmetric guided wave modes may vary as the guided wave moves along the wire.
[0070] As used in this document, the term millimeter wave can refer to electromagnetic waves / signals that are within the frequency range of millimeter wave from 30 GHz to 300 GHz. The term microwave can refer to waves / electromagnetic signals that are within a microwave frequency band from 300 MHz to 300 GHz. The term radio frequency or RF can refer to electromagnetic waves / signals that are within the 10 kHz to 1 radio frequency band THz. It is recognized that wireless signals, electrical signals and guided electromagnetic waves as described
Petition 870190094101, of 9/19/2019, p. 25/263
19/206 in the disclosure under discussion can be configured to operate in any desirable frequency range, such as, for example, frequencies within, above or below millimeter wave and / or microwave frequency bands. In particular, when a coupling device or transmission means includes a conductive element, the frequency of the guided electromagnetic waves that are carried by the coupling device and / or propagate along the transmission medium may be less than the average collision frequency of the electrons in the conductive element. In addition, the frequency of guided electromagnetic waves that are carried by the coupling device and / or propagate along the transmission medium can be a non-optical frequency, for example a radio frequency below the optical frequency range that starts at 1 THz.
[0071] As used in this document, the term antenna can refer to a device that is part of a transmission or reception system to transmit / radiate or receive wireless signals.
[0072] According to one or more modalities, an intelligent launcher includes an impedance adaptation circuit that has one or more elements of adjustable circuits, in which impedance adaptation circuit receives an input radio frequency (RF) signal and generates an outgoing RF signal in response to the incoming RF signal. A guided wave launcher is configured to generate, in response to the outgoing RF signal, an electromagnetic wave guided along a surface of a transmission medium, in which the electromagnetic wave propagates along the surface of the transmission medium.

20/206 transmission without requiring an electrical return path, and where the electromagnetic wave has a non-optical carrier frequency. A mismatch probe is configured to generate a mismatch signal based on the outgoing RF signal, where the mismatch signal indicates an impedance mismatch of the guided wave launcher. A controller is configured to generate one or more control signals in response to the mismatch signal, in which the one or more control signals adjust the one or more adjustable circuit elements of the impedance adaptation circuit, in which the adjustment of the one or more adjustable circuit elements facilitates the reduction of the impedance mismatch of the guided wave launcher.
[0073] According to one or more modalities, a method includes receiving an incoming radio frequency (RF) signal in an impedance adaptation circuit from a transmitter; generate, through the impedance adaptation circuit, an outgoing RF signal in response to the incoming RF signal; generate, in response to the outgoing RF signal and by means of a guided wave launcher, an electromagnetic wave guided along a surface of a transmission medium, in which the electromagnetic wave propagates along the surface of the transmission medium without requiring an electrical return path, and in which the transmission medium is opaque to optical signals; generating a mismatch signal based on the output RF signal, where the mismatch signal indicates an impedance mismatch of the guided wave launcher; generate one or more control signals in response to the mismatch signal; and adjust in response

[0074] According to one or more modalities, a device includes circuit means for receiving an incoming radio frequency (RF) signal in an impedance adaptation circuit and generating an outgoing RF signal in response to the incoming RF signal. input; launcher means for generating, in response to the outgoing RF signal, an electromagnetic wave guided along a surface of a transmission medium, where the electromagnetic wave propagates along the surface of the transmission medium without requiring a path of electrical return, and where the electromagnetic wave has a non-optical carrier frequency; probe means for generating a mismatch signal based on the output RF signal, wherein the mismatch signal indicates an impedance mismatch of the launcher means; and controller means for generating one or more control signals in response to the mismatch signal, wherein the one or more control signals adjust an impedance of the circuit means, where the impedance reduces the mismatch impedance of the launcher means.
[0075] Referring now to Figure 1, a block diagram 100 is shown illustrating a non-limiting example of a guided wave communications system. In
Petition 870190094101, of 9/19/2019, p. 28/263
22/206 operation, a transmission device 101 receives one or more communication signals 110 from a communication network or other communication device that includes data and generates guided waves 120 to conduct the data via the transmission medium 125 to the device transmission device 102. The transmission device 102 receives the guided waves 120 and converts them into communication signals 112 which include the data for transmission to a communications network or other communications device. Guided waves 120 can be modulated to conduct data via a modulation technique, such as, for example, phase shift switching, frequency shift switching, quadrature amplitude modulation, amplitude modulation, multiple carrier modulation, such as, for example, orthogonal frequency division multiplexing and multiple access techniques, such as frequency division multiplexing, time division multiplexing, code division multiplexing, propagation modes multiplexing different waveforms and via other modulation and access strategies.
[0076] The communication network or networks may include a wireless communication network, such as a mobile data network, a cellular data and voice network, a wireless local area network (for example, WiFi network or 802.xx), a satellite communications network, a personal area network, or other wireless network. The communication network or networks may also include a wired communication network, such as a telephone network, an Ethernet network, an

Communication devices can include a network edge device, a bridge device or a home gateway, a digital converter, a broadband modem, a telephone adapter, an access point, a base or other fixed communication device, a mobile communication device, such as an automotive or automobile connection port, laptop, tablet, smartphone, cell phone or other communication device.
[0077] In an example embodiment, the guided wave communication system 100 can operate in a bidirectional manner where the transmission device 102 receives one or more communication signals 112 from a network or communication device that includes other data and generates guided waves 122 to conduct the other data via the transmission means 125 to the transmission device 101. In this mode of operation, the transmission device 101 receives the guided waves 122 and converts them into communication signals 110 that include the others data for transmission to a network or communications device. Guided waves 122 can be modulated to conduct data via a modulation technique, such as, for example, phase shift switching, frequency shift switching, quadrature amplitude modulation, amplitude modulation, multiple carrier modulation, such as orthogonal frequency division multiplexing

24/206 and via multiple access techniques, such as frequency division multiplexing, time division multiplexing, code division multiplexing, multiplexing via different wave propagation modes and via other modulation and access strategies.
The transmission means 125 may include a cable having at least an inner portion surrounded by a dielectric material, such as, for example, an insulator or other dielectric protection, cover or other dielectric material, the dielectric material having an outer surface and a corresponding circumference. In an example embodiment, transmission means 125 operates as a single wire transmission line to guide the transmission of an electromagnetic wave. When the transmission means 125 is implemented as a single wire transmission system, it may include a wire. The yarn can be insulated or non-insulated and monofilament or multifilament (for example braided). In other embodiments, the transmission medium 125 may contain conductors of other shapes or configurations including bundles of wires, cables, rods, rails, tubes. In addition, the transmission means 125 may include non-conductors, such as, for example, tubes, rods, dielectric gutters or other dielectric members; combinations of conductors and dielectric materials, conductors without dielectric materials or other means of guided wave transmission. It should be noted that the transmission means 125 can then include any of the previously discussed means of transmission.

25/206 [0079] In addition, as previously discussed, guided waves 120 and 122 can be contrasted with radio transmissions in free space / air or conventional propagation of power or electrical signals through the conductor of a wire via an electrical circuit . In addition to the propagation of guided waves 120 and 122, the transmission means 125 may optionally contain one or more wires that propagate electrical power or other communication signals in a conventional manner as part of one or more electrical circuits.
[0080] With reference now to Figure 2, a block diagram 200 is shown illustrating a non-limiting example of a transmission device. The transmission device 101 or 102 includes a communications interface (I / F) 205, a transceiver 210 and a coupler 220.
[0081] In an example of operation, the communications interface 205 receives a communication signal 110 or 112 that includes data. In various embodiments, the communications interface 205 may include a wireless interface for receiving a wireless communication signal in accordance with a standard wireless protocol, such as, for example, LTE or another cellular voice and data protocol, a WiFi or 802.11 protocol, WIMAX protocol, Ultra-Broadband protocol, Bluetooth protocol, Zigbee protocol, a direct broadcast satellite (DBS) or other satellite communication protocol or other wireless protocol. In addition or alternatively, the communications interface 205 includes a wired interface that operates according to an Ethernet protocol, universal serial bus (USB) protocol, a data service interface specification protocol

26/206 cable (DOCSIS), a digital subscriber line protocol (DSL), a Firewire protocol (IEEE 1394) or another wired protocol. In addition to standards-based protocols, the 205 communications interface can operate in conjunction with another wired or wireless protocol. In addition, the communications interface 205 can optionally operate in conjunction with a protocol stack that includes multiple protocol layers including a MAC protocol, a transport protocol, an application protocol, etc.
[0082] In an example of operation, transceiver 210 generates an electromagnetic wave based on the communication signal 110 or 112 to conduct the data. The electromagnetic wave has at least one carrier frequency and at least one corresponding wavelength. The carrier frequency can be within a millimeter wave frequency band from 30 GHz to 300 GHz, such as, for example, 60 GHz, or a carrier frequency in the range of 30 to 40 GHz or a lower frequency band of 300 MHz to 30 GHz in the microwave frequency range, such as 26 to 30 GHz, 11 GHz, 6 GHz or 3 GHz, but it will be recognized that other carrier frequencies in other modalities are possible. In an operating mode, transceiver 210 merely converts the 110 or 112 communications signal or signals to a higher value for transmitting the electromagnetic signal in the microwave wave or millimeter wave as a guided electromagnetic wave that is guided by, or turned on to the transmission medium 125. In another mode of operation, the communications interface 205 or converts the communication signal 110 or 112 into a baseband signal or
Petition 870190094101, of 9/19/2019, p. 33/263
27/206 almost baseband or extracts data from communication signal 110 or 112, and transceiver 210 modulates a high frequency carrier with the data, baseband signal or near baseband for transmission. It should be recognized that transceiver 210 can modulate data received via communication signal 110 or 112 to preserve one or more data communication protocols of communication signal 110 or 112, either by encapsulation in the payload of a different protocol, either by simple frequency shift. Alternatively, transceiver 210 can then translate the data received via communication signal 110 or 112 to a protocol that is different from the data communication protocol or protocols of communication signal 110 or 112.
[0083] In an example of operation, coupler 220 couples the electromagnetic wave in the transmission medium 125 as a guided electromagnetic wave to conduct the 110 or 112 communications signal or signals. Although the previous description has focused on the operation of transceiver 210 as a transmitter, transceiver 210 can also operate to receive electromagnetic waves that conduct other data from the single wire transmission medium via coupler 220 and to generate communications signals 110 or 112 via communications interface 205 which includes the others Dice. The modalities where an additional guided electromagnetic wave conducts other data that are also propagated along the transmission medium 125 must be considered. Coupler 220 can also couple that electromagnetic wave

28/206 of transmission medium 125 on transceiver 210 for reception.
[0084] The transmission device 101 or 102 includes an optional training controller 230. In an example embodiment, the training controller 230 is implemented by a stand-alone processor or a processor that is shared with one or more other components of the training device. transmission 101 or 102. Training controller 230 selects carrier frequencies, modulation schemes and / or guided wave modes for guided electromagnetic waves based on feedback data received by transceiver 210 from at least one transmitting device remote coupled to receive the guided electromagnetic wave.
[0085] In an example embodiment, a guided electromagnetic wave transmitted by a remote transmission device 101 or 102 carries data that also propagates along the transmission medium 125. Data from the remote transmission device 101 or 102 can be generated to include feedback data. In operation, the coupler 220 also couples the guided electromagnetic wave of the transmission medium 125 and the transceiver receives the electromagnetic wave and processes the electromagnetic wave to extract the feedback data.
[0086] In an example embodiment, the training controller 230 operates based on the feedback data to evaluate a plurality of candidate frequencies, modulation schemes and / or transmission modes to select a carrier frequency, a modulation scheme and / or a mode
Petition 870190094101, of 9/19/2019, p. 35/263
29/206 transmission to improve performance, such as throughput, signal strength, and reduce propagation loss, etc.
[0087] The following examples should be considered: a transmission device 101 begins operation under the control of training controller 230 by sending a plurality of guided waves as test signals, such as pilot waves or other test signals, in a corresponding plurality of candidate frequencies and / or candidate modes directed to a remote transmission device 102 coupled to the transmission medium 125. The guided waves may include, in addition or alternatively, test data. The test data can indicate the frequency and / or the guide wave mode for particular candidates of the signal. In one embodiment, the training controller 230 on the remote transmission device 102 receives the test signals and / or test data from any of the guided waves that have been properly received and determines the best candidate frequency and / or guided wave mode , a group of acceptable candidate frequencies and / or guided wave modes, or an ordering classification of candidate frequencies and / or guided wave modes. This selection of candidate frequency (s) and / or guided mode (s) is generated by the training controller 230 based on one or more optimization criteria, such as received signal strength, rate bit error, packet error rate, signal-to-noise ratio, loss of propagation, etc. The training controller 230 generates feedback data that indicates the selection of frequency (s) and / or wave mode (s)
Petition 870190094101, of 9/19/2019, p. 36/263
30/206 guided candidate (s) and sends feedback data to transceiver 210 for transmission to transmission device 101. Transmission device 101 and 102 can then communicate data to each other based on the frequency (s) and / or selection candidate guided wave mode (s).
[0088] In other modalities, the guided electromagnetic waves containing the test signals and / or test data are reflected again, repeated again or returned by the remote transmission device 102 to the transmission device 101 for reception and analysis by the controller training 230 of the transmission device 101 that started these waves. For example, the transmission device 101 can send a signal to the remote transmission device 102 to initiate a test mode where a physical reflector is connected to the line, a termination impedance is changed to cause reflections, a return mode is connected to re-couple electromagnetic waves on the source transmission device 102, and / or a repeater mode is activated to amplify and retransmit the electromagnetic waves back to the source transmission device 102. Training controller 230 on the source transmission device 102 receives the test signals and / or test data from any of the guided waves that have been properly received and determines the selection of candidate frequency (s) and / or guided wave mode (s).
[0089] Although the above procedure has been described in a start-up or start-up operation mode, each 101 or 102 transmission device can send test signals, evaluate candidate frequencies or guided wave modes
Petition 870190094101, of 9/19/2019, p. 37/263
31/206 via a non-test route, such as, for example, normal transmissions, or to evaluate candidate frequencies or guided wave modes equally at other times or continuously. In an example embodiment, the communication protocol between transmission devices 101 and 102 may include an on-demand or periodic test mode where complete tests or more limited tests of a subgroup of frequencies and guided wave modes candidates are tested and evaluated . In other modes of operation, re-entry into this test mode can be triggered by a performance degradation due to disturbance, weather conditions, etc. In an example embodiment, the receiver bandwidth of transceiver 210 is either large enough or scanned to receive all candidate frequencies or can be selectively adjusted by training controller 230 to a training mode where the receiver's bandwidth of the transceiver 210 is large enough or scanned to receive all candidate frequencies.
[0090] With reference now to Figure 3, a graphical diagram 300 is shown illustrating a non-limiting example of an electromagnetic field distribution. In this embodiment, an air transmission means 125 includes an internal conductor 301 and an insulating casing 302 of dielectric material, as shown in cross section. Diagram 300 includes different gray scales that represent different electromagnetic field forces generated by the propagation of the guided wave having an asymmetric and non-fundamental guided wave mode.
Petition 870190094101, of 9/19/2019, p. 38/263
32/206 [0091] In particular, the electromagnetic field distribution corresponds to a better modal location that improves the propagation of guided electromagnetic waves over an isolated transmission medium and reduces the loss of point-to-point transmission. In this particular mode, the electromagnetic waves are guided by the transmission medium 125 to propagate along an outer surface of the transmission medium, in this case, the outer surface of the insulating housing 302. The electromagnetic waves are partially incorporated in the insulator and radiate partially on the outer surface of the insulator. In this way, electromagnetic waves are lightly coupled to the insulator in order to allow electromagnetic wave propagation over long distances with low loss of propagation.
[0092] As shown, the guided wave has a field structure that is essentially or substantially outside the transmission medium 125 that serves to guide the electromagnetic waves. The regions inside the conductor 301 have little or no field. Likewise, the regions within the insulating housing 302 have low field strength. Most of the electromagnetic field strength is distributed in the lugs 304 on the outer surface of the insulating housing 302 and close to it. The presence of an asymmetric guided wave mode is shown by the high electromagnetic field forces at the top and bottom of the outer surface of the insulating enclosure 302 (in the diagram orientation), as opposed to very small field forces on the other sides of the insulating enclosure 302.
Petition 870190094101, of 9/19/2019, p. 39/263
33/206 [0093] The example shown corresponds to a 38 GHz electromagnetic wave guided by a wire with a diameter of 1.1 cm and dielectric insulation with a thickness of 0.36 cm. Since the electromagnetic wave is guided by the transmission medium 125 and most of the field strength is concentrated in the air outside the insulating shell 302 within a limited distance from the outer surface, the guided wave can propagate longitudinally through the transmission medium 125 with a very low loss. In the example shown, this limited distance corresponds to a distance from the outer surface that is less than half the largest cross-sectional dimension of the transmission medium 125. In this case, the largest cross-sectional dimension of the wire corresponds to the overall diameter of 1.82 cm, however, this value can vary with the size and shape of the transmission medium 125. For example, if the transmission medium 125 has a rectangular shape with a height of 0.3 cm and a width of 0.4 cm, the dimension in cross-section, the diagonal of 0.5 cm would be greater and the corresponding limited distance would be 0.25 cm. The dimensions of the area containing most of the field strength vary equally with frequency and, in general, increase as carrier frequencies decrease.
[0094] Likewise, it should be noted that the components of a guided wave communication system, such as, for example, couplers and transmission means, can have their own cutoff frequencies for each guided wave mode. The cutoff frequency generally has the lowest frequency at which a particular guided wave mode was designed
Petition 870190094101, of 9/19/2019, p. 40/263
34/206 to be supported by that particular component. In an example embodiment, the particular asymmetric mode of propagation shown is induced in the transmission medium 125 by an electromagnetic wave having a frequency that is within a limited range (such as, for example, Fc at 2Fc) of the cut-off frequency low Fc for that particular asymmetric mode. The lower cutoff frequency Fc is particular to the characteristics of the transmission medium 125.
For embodiments, as shown, that include an inner conductor 301 surrounded by an insulating jacket 302, this cutoff frequency can vary based on the dimensions and properties of the insulating jacket 302 and potentially the dimensions and properties of the inner conductor 301 and can be determined experimentally to have a desired pattern pattern. However, it should be noted that similar effects can be found for a hollow insulator or dielectric without an inner conductor. In this case, the cut-off frequency can vary based on the dimensions and properties of the hollow insulator or dielectric.
[0095] At frequencies lower than the lower cutoff frequency, the asymmetric mode is difficult to induce in the transmission medium 125 and cannot propagate over all distances, except trivial ones. As the frequency rises above the limited frequency range around the cutoff frequency, the asymmetric mode moves further and further into the insulating housing 302. At frequencies much higher than the cutoff frequency, the field strength ceases to be concentrated outside the insulating shell, but essentially within the insulating shell 302.

35/206
Although the transmission medium 125 provides strong electromagnetic wave orientation and propagation is still possible, the ranges are more limited by greater losses due to propagation within the insulating housing 302, as opposed to the surrounding air.
[0096] With reference now to Figure 4, a graphical diagram 400 is shown illustrating a non-limiting example of an electromagnetic field distribution. In particular, a cross-sectional diagram 400 similar to Figure 3 with common reference numbers used to refer to similar elements is shown. The example shown corresponds to a 60 GHz wave guided by a wire with a diameter of 1.1 cm and dielectric insulation with a thickness of 0.36 cm. Since the frequency of the guided wave is above the limited cutoff frequency of that particular asymmetric way, much of the field strength has shifted into the insulating shell 302. In particular, the field strength is concentrated essentially inside insulation 302. Although the transmission medium 125 provides a strong orientation to the electromagnetic wave and propagation is still possible, the ranges are more limited when compared with the modality of Figure 3, due to greater losses due to the propagation inside the insulating enclosure 302.
[0097] With reference now to Figure 5A, a graphic diagram is shown illustrating a non-limiting example of a frequency response. In particular, diagram 500 presents a point-to-point loss graph (in dB) as a function of frequency, superimposed by
Petition 870190094101, of 9/19/2019, p. 42/263
36/206 electromagnetic field distributions 510, 520 and 530 at three points for a 200 cm insulated medium voltage wire. The limit between the insulator and the surrounding air is represented by the reference number 525 in each electromagnetic field distribution.
[00 98] As discussed in conjunction with Figure 3, an example of a desired asymmetric mode of propagation shown is induced in the transmission medium 125 by an electromagnetic wave having a frequency that is within a limited range (such as, for example , Fc to 2Fc) of the lowest cutting power Fc of the transmission medium for that particular asymmetric mode. In particular, the 520 to 6 GHz electromagnetic field distribution is found in this best modal location that improves the electromagnetic wave propagation over an isolated transmission medium and reduces the loss of point-to-point transmission. In this particular mode, the guided waves are partially incorporated into the insulator and partially irradiate on the outer surface of the insulator. In this way, the electromagnetic waves are lightly coupled to the insulator in order to allow the propagation of guided electromagnetic waves over long distances with low loss of propagation.
[0099] At lower frequencies represented by the 510 to 3 GHz electromagnetic field distribution, the asymmetric mode radiates more strongly, generating greater propagation losses. At higher frequencies represented by the 530 to 9 GHz electromagnetic field distribution, the asymmetric mode moves more and more into the
Petition 870190094101, of 9/19/2019, p. 43/263
37/206 insulating casing providing too much absorption, again generating greater propagation losses.
[0100] With reference now to Figure 5B, a graphic diagram 550 is shown illustrating non-limiting modalities of example of a longitudinal cross-section of a transmission medium 125, such as, for example, an insulated wire, representing fields of electromagnetic waves guided in various operating frequencies. As shown in diagram 556, when the guided electromagnetic waves are approximately at the cutoff frequency (f _c ) corresponding to the best modal location, the guided electromagnetic waves are loosely coupled to the insulated wire, so that absorption is reduced, and the fields guided electromagnetic waves are switched on sufficiently to reduce the amount radiated to the environment (eg air). Since the absorption and radiation of the fields of the guided electromagnetic waves are low, the propagation losses are consequently low, allowing the propagation of guided electromagnetic waves over greater distances.
[0101] As shown in diagram 554, propagation losses increase when an operating frequency of the guided electromagnetic waves increases above about twice the cutoff frequency (f _c ) or, as mentioned, above the range of the best location. More of the field strength of the electromagnetic wave is triggered inside the insulating layer, increasing propagation losses. At frequencies much higher than the cutoff frequency (fc), the guided electromagnetic waves are strongly linked to the isolated wire as a result of the fields emitted by the waves

38/206 guided electromagnetic being concentrated in the insulation layer of the wire, as shown in diagram 552. This in turn further increases the propagation losses due to the absorption of the electromagnetic waves guided by the insulation layer. Similarly, propagation losses increase when the operating frequency of guided electromagnetic waves is substantially below the cutoff frequency (íc), as shown in diagram 558. At frequencies much lower than the cutoff frequency (f _c ), the waves Guided electromagnetic waves are weakly (or nominally) connected to the insulated wire and therefore tend to radiate to the environment (for example, air), which in turn increases propagation losses due to the radiation of the guided electromagnetic waves.
[0102] With reference now to Figure 6, a graphical diagram 600 is shown illustrating a non-limiting example of an electromagnetic field distribution. In this embodiment, a transmission medium 602 is a bare wire as shown in cross section. Diagram 300 includes different gray scales representing different electromagnetic field forces generated by the propagation of a guided wave having a symmetrical and fundamental guided wave mode at a single carrier frequency.
[0103] In this particular mode, the electromagnetic waves are guided by the transmission medium 602 to propagate along an outer surface of the transmission medium, in this case, the outer surface of the bare wire. Electromagnetic waves are lightly coupled to the wire in order to allow electromagnetic wave propagation in
Petition 870190094101, of 9/19/2019, p. 45/263
39/206 long distances with low propagation loss. As shown, the guided wave has a field structure that lies substantially outside the transmission medium 602 which serves to guide the electromagnetic waves. The regions inside the conductor 602 have little or no field.
[0104] Referring now to Figure 7, a block diagram 700 is shown illustrating a non-limiting example of an arc coupler. In particular, a coupling device for use in a transmission device, such as a transmission device 101 or 102 shown in conjunction with Figure 1, is shown. The coupling device includes an arc coupler 704 coupled in a transmitter circuit 712 and termination or damper 714. The arc coupler 704 can be made of a dielectric material, or another low loss insulator (eg Teflon, polyethylene, etc.), or made of a conductive material (eg , metallic, non-metallic, etc.) or any combination of the aforementioned materials. As shown, the arc coupler 704 operates as a waveguide and has a 706 wave propagating as a guided wave around a waveguide surface of the arc coupler 704. In the embodiment shown, at least a portion of the coupler arc 704 can be placed next to a wire 702 or other transmission medium (such as, for example, transmission medium 125), in order to facilitate the coupling between the arc coupler 704 and wire 702 or another transmission medium, as described here to launch the guided wave 708 on the wire. The arc coupler 704 can be placed so that a portion of the curved arc coupler 704 is
Petition 870190094101, of 9/19/2019, p. 46/263
40/206 tangential and parallel or substantially parallel to wire 702. The arc coupler portion 704 parallel to the wire can be a corner of the curve or any point where a tangent to the curve is parallel to wire 702. When the arc coupler 704 is so positioned or placed, wave 706 moving along arc coupler 704 engages, at least in part, with wire 702 and propagates as a guided wave 708 around or around the surface of wire 702 and longitudinally along the wire 702. Guided wave 708 can be characterized as a surface wave or other electromagnetic wave that is guided by, or connected to, wire 702 or other means of transmission.
[0105] A portion of wave 706 that is not coupled to wire 7 02 propagates as a wave 710 along arc coupler 704. It will be recognized that arc coupler 704 can be configured and arranged in a variety of positions with respect to to wire 702 to achieve a desired level of coupling or non-coupling of wave 706 on wire 702. For example, the curvature and / or the length of arc coupler 704 that is parallel or substantially parallel, as well as its separation distance (which may include zero separation distance in one embodiment), wire 702 may vary without departing from the example embodiments. Likewise, the arrangement of arc coupler 704 in relation to wire 702 may vary based on considerations of the respective intrinsic characteristics (eg thickness, composition, electromagnetic properties, etc.) of wire 702 and arc coupler 704, as well as characteristics
Petition 870190094101, of 9/19/2019, p. 47/263
41/206 (for example, frequency, energy level, etc.) of 706 and 708 waves.
[0106] Guided wave 708 remains parallel or substantially parallel to wire 702, even while wire 702 bends and folds. Curves in wire 702 can increase transmission losses, which are also dependent on wire diameters, frequency and materials. If the dimensions of the arc coupler 704 are chosen for efficient power transfer, most of the power on wave 706 is transferred to wire 702, with little power remaining on wave 710. It will be recognized that the guided wave 708 may still have a multimodal nature (discussed here), including having modes that are non-fundamental or asymmetric, while moving along a path parallel or substantially parallel to wire 702, with or without a fundamental transmission mode. In one embodiment, non-fundamental or asymmetric modes can be used to minimize transmission losses and / or obtain greater propagation distances.
[0107] It is noted that the term parallel is generally a geometric construction that is often not exactly achievable in real systems. Consequently, the term parallel as used in the disclosure under discussion represents an approximation rather than an exact configuration when used to describe modalities disclosed in the disclosure under discussion. In one embodiment, substantially parallel may include approximations that are within 30 degrees of true parallelism in all dimensions.
Petition 870190094101, of 9/19/2019, p. 48/263
42/206 [0108] In one mode, the 706 wave can display one or more wave propagation modes. The arc coupler modes can be dependent on the shape and / or design of the 704 coupler. One or more 706 arc coupler modes can generate, influence or affect one or more wave propagation modes of the guided wave 708 propagating along of wire 702. However, it should be particularly noted that the guided wave modes present in the guided wave 706 may be the same or different from the guided wave modes of the guided wave 708. In this way, one or more guided wave modes of the guided wave 706 may not be transferred to the guided wave 708, and one or more supplementary guided wave modes of guided wave 708 may not have been present in the guided wave 706. Also, it should be noted that the cutoff frequency of the arc coupler 704 for a The particular guided wave mode may be different from the cutting frequency of wire 702 or another transmission medium for that same mode. For example, although wire 702 or another transmission medium can be operated slightly above its cutoff frequency for a particular guided wave mode, arc coupler 704 can be operated well above its cutoff frequency for that same mode for low loss, slightly below its cutoff frequency for that same mode to, for example, induce greater coupling and power transfer, or some other point in relation to the cutoff frequency of the arc coupler for that mode.
[0109] In one embodiment, the wave propagation modes on wire 702 can be similar to the arc coupler modes, since both 706 and 708 waves propagate in
Petition 870190094101, of 9/19/2019, p. 49/263
43/206 around the outside of the arc coupler 704 and the wire 702, respectively. In some embodiments, as the 706 wave engages the wire 702, the modes can change shape, or new modes can be created or generated due to the coupling between the arc coupler 704 and the wire 702. For example, the differences in size, material and / or impedances of the arc coupler 704 and wire 702 can create additional modes not present in the arc coupler modes and / or suppress some of the arc coupler modes. The wave propagation modes can comprise the fundamental transverse electromagnetic mode (Quasi-TEMoo), where only small electric and / or magnetic fields extend in the direction of propagation, and the electric and magnetic fields extend radially outward while the guided wave propagates along the wire. This guided wave mode may have a threaded shape, where there are some of the electromagnetic fields within the arc coupler 704 or the wire 702.
[0110] The waves 706 and 708 can comprise a fundamental TEM mode where the fields extend radially outward and also comprise other non-fundamental modes (for example, asymmetric, top level, etc.). Although the particular wave propagation modes are discussed above, other wave propagation modes are also possible, such as, for example, transverse electrical (TE) and transverse magnetic (TM) modes, based on the frequencies employed, in the coupler design of arc 704, in the dimensions and composition of wire 702, as well as in its surface characteristics, its insulation, if present, electromagnetic properties of the surrounding environment, etc. Must be
Petition 870190094101, of 9/19/2019, p. 50/263
44/206 noted that, depending on the frequency, the electrical and physical characteristics of the 702 wire and the particular wave propagation modes that are generated, the guided wave 708 can move along the conductive surface of an oxidized uninsulated wire, a non-oxidized uninsulated wire, an insulated wire and / or along the insulating surface of an insulated wire.
[0111] In one embodiment, the diameter of the arc coupler 704 is less than the diameter of the wire 702. For the millimeter band wavelength used, the arc coupler 704 supports a single waveguide mode that constitutes the wave 706. This single waveguide mode may change as it is coupled to wire 702 as a guided wave 708. If the arc coupler 704 were larger, it would be possible to support more than one waveguide mode, but these guide modes Additional waveforms may not be coupled to wire 702 as efficiently and larger coupling losses may occur. However, in some alternative embodiments, the diameter of the arc coupler 704 may be equal to or greater than the diameter of the wire 702, for example, when larger coupling losses are desirable or when they are used in conjunction with other techniques to then reduce losses coupling (for example, adaptation of tapered impedances, etc.).
[0112] In one embodiment, the wavelength of waves 706 and 708 is comparable in size or less to a circumference of the arc coupler 704 and the wire 702. In an example, if the wire 702 has a diameter of 0.5 cm and a corresponding circumference of about 1.5 cm, the transmission wavelength is about 1.5 cm or
Petition 870190094101, of 9/19/2019, p. 51/263
45/206 less, corresponding to a frequency of 70 GHz or higher. In another embodiment, a suitable frequency of transmission and the carrier wave signal is in the range of 30 to 100 GHz, possibly about 30 to 60 GHz and about 38 GHz in one example. In one embodiment, when the circumference of the arc coupler 704 and the wire 702 is comparable in size to, or greater than, a transmission wavelength, waves 706 and 708 can exhibit multiple wave propagation modes including fundamental and / or non-fundamental (symmetrical and / or asymmetric) that propagate over sufficient distances to support the various communication systems described here. Consequently, waves 706 and 708 can comprise more than one type of electric and magnetic field configuration. In one embodiment, as the guided wave 708 travels over the wire 702, the electrical and magnetic field settings will remain the same from one end of the other to the wire 702. In other modalities, as the guided wave 708 encounters interference ( distortion or obstructions) or lose energy due to transmission or dispersion losses, the electric and magnetic field settings may change as the guided wave 708 travels over wire 702.
[0113] In one embodiment, the 704 arc coupler can be composed of nylon, Teflon, polyethylene, a polyamide or other plastics. In other embodiments, other dielectric materials are possible. The surface of the wire 702 can be metallic with a bare metal surface or can be insulated using plastic, dielectric, insulator or other covering, wrapping or capping. In one embodiment, a
Petition 870190094101, of 9/19/2019, p. 52/263
46/206 dielectric or otherwise non-conductive / insulated waveguide can be paired with bare / metallic wire or insulated wire. In other embodiments, a metallic and / or conductor waveguide can be paired with a bare / metallic wire or insulated wire. In one embodiment, an oxidation layer on the bare metal surface of wire 702 (for example, resulting from exposure of the bare metal surface to oxygen / air) can also provide insulating or dielectric properties similar to those provided by some insulators or coverings.
[0114] It is noted that the graphical representations of the 706, 708 and 710 waves are presented merely to illustrate the principles that the 706 wave induces or else launches a 708 guided wave on a 702 wire that operates, for example, as a line of single wire transmission. Wave 710 represents the portion of wave 706 that remains in the arc coupler 704 after the generation of the guided wave 708. The effective electric and magnetic fields generated as a result of this wave propagation may vary depending on the frequencies employed, the mode or modes of particular wave propagation, the design of the arc coupler 704, the dimensions and composition of the wire 702, as well as its surface characteristics, its optional insulation, the electromagnetic properties of the surrounding environment, etc.
[0115] It is noted that the arc coupler 704 may include a termination circuit or damper 714 at the end of the arc coupler 704 that can absorb radiation or remaining energy from wave 710. The termination circuit or damper 714 can prevent and / or minimize radiation

47/206 remnant of wave 710 reflecting again in the direction of transmitter circuit 712. In one embodiment, the termination circuit or damper 714 may include terminating resistors and / or other components that effect impedance adaptation to attenuate reflection. In some embodiments, if the coupling efficiencies are high enough and / or the 710 wave is small enough, it may not be necessary to use a 714 terminating or damping circuit. For simplicity, these 712 transmitting and terminating or damping circuits 714 may not be represented in the other figures, but in these embodiments, transmitting and terminating circuits or dampers may possibly be used.
[0116] In addition, although a single arc coupler 704 is generated that generates a single guided wave 708, multiple arc couplers 704 placed at different points along wire 702 and / or in different azimuth orientations around the wire can be employed to generate and receive multiple guided waves 708 at the same or different frequencies, at the same or different phases and in the same or different wave propagation modes.
[0117] In Figure 8, a block diagram 800 is shown illustrating a non-limiting example of an arc coupler. In the embodiment shown, at least a portion of the coupler 704 can be placed next to a wire 702 or other transmission medium (such as, for example, transmission medium 125), in order to facilitate the coupling between the arc coupler 704 and the wire 702 or other transmission medium, to extract a portion of the guided wave 806 as
Petition 870190094101, of 9/19/2019, p. 54/263
48/206 guided wave 808 as described herein. The arc coupler 704 can be placed so that a portion of the curved arc coupler 704 is tangential and parallel or substantially parallel to the wire 702. The arc coupler portion 704 parallel to the wire can be a corner of the curve or any point where a tangent of the curve is parallel to the wire 702. When the arc coupler 704 is so positioned or placed, the wave 806 moving along the wire 702 engages, at least in part, in the arc coupler 704 and propagates as a wave guided 808 along the arc coupler 704 to a receiving device (not expressly shown). A portion of wave 806 that does not engage the arc coupler propagates as wave 810 along wire 702 or another transmission medium.
[0118] In one mode, wave 80 6 can display one or more wave propagation modes. The arc coupler modes can be dependent on the shape and / or design of the coupler 704. One or more guided wave modes 806 can generate, influence or affect one or more guide wave modes of the guided wave 808 propagating along the coupler of arc 704. However, it should be particularly noted that the guided wave modes present in the guided wave 806 may be the same or different from the guided wave modes of the guided wave 808. In this way, one or more guided wave modes of the guided wave 80 6 may not be transferred to the guided wave 808, and one or more supplementary guided wave modes of the guided wave 808 may not have been present in the guided wave 806.
Petition 870190094101, of 9/19/2019, p. 55/263
49/206 [0119] Referring now to Figure 9A, a block diagram 900 is shown illustrating a non-limiting example of a stub coupler. In particular, a coupling device is provided that includes a stub coupler 904 for use in a transmission device, such as a transmission device 101 or 102 shown in conjunction with Figure 1. The stub coupler 904 it can be made of a dielectric material, or other low loss insulator (for example, Teflon, polyethylene, etc.), or made of a conductive material (for example, metallic, non-metallic, etc.) or any combination of the above materials . As shown, stub coupler 904 operates as a waveguide and has a 906 wave propagating as a guided wave around a waveguide surface of the 904 stub coupler. In the embodiment shown, at least a portion of the coupler stub 904 can be placed next to a wire 702 or other transmission medium (such as transmission medium 125), in order to facilitate coupling between stub coupler 904 and wire 702 or another transmission medium, as described here to launch the guided wave 908 on the wire.
[0120] In one embodiment, the stub coupler 904 is curved, and one end of the stub coupler 904 can be tied, attached, or mechanically coupled to a wire 702. When the end of the stub coupler 904 is attached to the wire 702 , the end of the stub coupler 904 is parallel or substantially parallel to the wire 702. Alternatively, another portion of the dielectric waveguide in addition to one end can be fixed or coupled to the wire 702 so
Petition 870190094101, of 9/19/2019, p. 56/263
50/206 that the fixed or coupled portion is parallel or substantially parallel to wire 702. The fastener 910 can be a retention of nylon cable or other type of non-conductive / dielectric material that is either separated from the stub coupler 904 or constructed as an integrated component of the stub coupler 904. The stub coupler 904 can be adjacent to the wire 702 without surrounding the wire 702.
[0121] As the arc coupler 704 described in conjunction with Figure 7, when the stub coupler 904 is placed with the end parallel to the wire 702, the guided wave 906 moving along the stub coupler 904 is coupled to the wire 702 and propagates as a guided wave 908 around the surface of the wire 702. In an example embodiment, the guided wave 908 can be characterized by a surface wave or another electromagnetic wave.
[0122] It is noted that the graphic representations of waves 906 and 908 are presented merely to illustrate the principles that wave 906 induces or launches a guided wave 908 on a wire 702 that operates, for example, as a transmission line of single wire. The effective electric and magnetic fields generated as a result of this wave propagation can vary depending on one or more between the shape and / or design of the coupler, the relative position of the dielectric waveguide in relation to the wire, the frequencies used, the design of the stub coupler 904, the dimensions and composition of wire 702, as well as its surface characteristics, its optional insulation, the electromagnetic properties of the surrounding environment, etc.
Petition 870190094101, of 9/19/2019, p. 57/263
51/206 [0123] In one embodiment, a stub coupler end 904 can taper toward wire 702 to increase coupling efficiencies. In fact, the tapering of the end of the stub coupler 904 can provide impedance adaptation to the wire 702 and reduce reflections, according to an example modality of the disclosure under discussion. For example, one end of the stub coupler 904 can gradually taper to obtain a desired level of coupling between waves 906 and 908 as illustrated in Figure 9A.
[0124] In one embodiment, holder 910 can be placed so that there is a short length of stub coupler 904 between holder 910 and one end of stub coupler 904. Maximum coupling efficiencies are realized in that embodiment when the length the end of the stub coupler 904 which is beyond the fastener 910 has at least several long wavelengths for whatever frequency is being transmitted.
[0125] Moving now to Figure 9B, a diagram 950 is shown illustrating a non-limiting example of an electromagnetic distribution according to several aspects described here. In particular, an electromagnetic distribution in two dimensions is presented for a transmission device that includes the coupler 952, shown in an example stub coupler constructed of a dielectric material. The 952 coupler couples an electromagnetic wave for propagation as a guided wave along
Petition 870190094101, of 9/19/2019, p. 58/263
52/206 of an outer surface of a 702 wire or other transmission medium.
[0126] Coupler 952 guides the electromagnetic wave to an xo junction via a symmetrical guided wave mode. Although some of the energy from the electromagnetic wave that travels along the coupler 952 is found outside the coupler 952, most of the energy from that electromagnetic wave is contained within the coupler 952. The xo junction couples the electromagnetic wave to wire 702 or other means transmission at an azimuth angle corresponding to the bottom of the transmission medium. This coupling induces an electromagnetic wave that is guided to propagate along the outer surface of wire 702 or other transmission medium via at least one wave mode guided in the 956 direction. Most of the energy of the guided electromagnetic wave is outside or, but close to the outer surface of wire 702 or other means of transmission. In the example shown, the xo junction forms an electromagnetic wave that propagates both in a symmetrical way and at least in an asymmetric surface mode, such as, for example, the first order mode presented together with Figure 3, that slides on the surface of the wire 702 or other transmission medium.
[0127] It is noted that the graphical representations of guided waves are presented merely to illustrate an example of propagation and guided wave coupling. The effective electric and magnetic fields generated as a result of this wave propagation can vary depending on the frequencies used, the design and / or the configuration of the 952 coupler,
Petition 870190094101, of 9/19/2019, p. 59/263
53/206 of the dimensions and composition of wire 702 or other means of transmission, as well as its surface characteristics, its insulation, if present, the electromagnetic properties of the surrounding environment, etc.
[0128] Now moving on to Figure 10A, a block diagram 1000 of an example non-limiting embodiment of a coupling and transceiver system is illustrated according to various aspects described here. The system is an example of a transmission device 101 or 102. In particular, communication interface 1008 is an example of communication interface 205, stub coupler 1002 is an example of coupler 220, and transmitter / receiver device 1006, the diplexer 1016, the power amplifier 1014, the low noise amplifier 1018, the frequency mixers 1010 and 1020 and the local oscillator 1012 collectively form an example of transceiver 210.
[0129] In operation, the transmitter / receiver device 1006 launches and receives waves (for example, guided wave 1004 on stub coupler 1002). Guided waves 1004 can be used to transport signals received from and sent to a host device, a base station, mobile devices, a building or other device via a communications interface 1008. The communications interface 1008 can be a part of integral with system 1000. Alternatively, communications interface 1008 may be linked to system 1000. Communications interface 1008 may comprise a wireless interface for interacting with the host device, base station, mobile devices, a building or another device using any
Petition 870190094101, of 9/19/2019, p. 60/263
54/206 one of several wireless signaling protocols (for example, LTE, WiFi, WiMAX, IEEE 802.xx, etc.) including an infrared protocol, such as an infrared data association (IrDA) protocol or other optical line-of-sight protocol. Communications interface 1008 can also comprise a wired interface, such as, for example, a fiber optic line, a coaxial cable, a twisted pair, a category 5 cable (CAT-5) or other suitable wired or optical media for communication with the host device, the base station, mobile devices, a building or other device via a protocol, such as an Ethernet protocol, universal serial bus (USB) protocol, a specification protocol cable data service interface (DOCSIS), a digital subscriber line protocol (DSL), a Firewire protocol (IEEE 1394), or another wired or optical protocol. For modalities where system 1000 functions as a repeater, communication interface 1008 may not be necessary.
[0130] The output signals (for example, Tx) of the communications interface 1008 can be combined with a carrier wave (for example, millimeter wave carrier wave) generated by a local oscillator 1012 in the frequency mixer 1010. The mixer of frequency frequency 1010 can use heterodination techniques or other frequency shifting techniques to shift the frequency of the output signals from the communications interface 1008. For example, the signals sent to and from the communications interface 1008 can be modulated signals, such as example, orthogonal frequency division (OFDM) multiplexed signals
Petition 870190094101, of 9/19/2019, p. 61/263
55/206 formatted according to a Wireless Long Term Evolution (LTE) protocol or other 3G, 4G, 5G or higher wireless voice and data protocol, a Zigbee, WIMAX, Ultra-Broadband or IEEE 802.11 wireless protocol ; a wired protocol, such as an Ethernet protocol, universal serial bus (USB) protocol, a cable data service interface specification protocol (DOCSIS), a digital subscriber line protocol (DSL), a Firewire protocol (IEEE 1394) or another wired or wireless protocol. In an example embodiment, this frequency conversion can be done in the analog domain and, as a result, the frequency shift can be done without considering the type of communications protocol used by a base station, mobile devices or devices in the building. As new communications technologies are developed, the 1008 communications interface can be upgraded (for example, updated with software, firmware and / or hardware) or replaced, and the transmission and frequency shift device can remain, simplifying upgrades . The carrier wave can then be sent to a power amplifier (PA) 1014 and can be transmitted via the transmitter / receiver device 1006 via the diplexer 1016.
[0131] The signals received from the transmitter / receiver device 1006 that are routed to the communications interface 1008 can be separated from other signals via the diplexer 1016. The received signal can then be sent to the low noise amplifier (LNA) 1018 to amplification. A 1020 frequency mixer, with
Petition 870190094101, of 9/19/2019, p. 62/263
56/206 the help of the local oscillator 1012, can reduce the received signal (found in the millimeter wave band or around 38 GHz in some modalities) to the native frequency. The communications interface 1008 can then receive the transmission on an input port (Rx).
[0132] In one embodiment, the transmitter / receiver device 1006 may include a cylindrical or non-cylindrical metal (which, for example, may be hollow in one embodiment, but not necessarily drawn to scale), or another conductive waveguide or not conductor and one end of stub coupler 1002 can be placed on or near the waveguide or transmitter / receiver device 1006, so that when the transmitter / receiver device 1006 generates a transmission, the guided wave is coupled to the coupler stub 1002 and propagate as a guided wave 1004 around the waveguide surface of stub coupler 1002. In some embodiments, guided wave 1004 may propagate partly on the outer surface of stub coupler 1002 and partly on the inside the stub coupler 1002. In other embodiments, the guided wave 1004 can propagate substantially or completely on the outer surface of the stub coupler 1002. In still other embodiments, the guided wave 1 004 can propagate substantially or completely within the stub coupler 1002. In the latter embodiment, the guided wave 1004 can radiate at one end of the stub coupler 1002 (such as, for example, the tapered end shown in Figure 4) for the coupling in a transmission medium, such as a wire 702 in Figure 7. Similarly, if the guided wave 1004 is arriving
Petition 870190094101, of 9/19/2019, p. 63/263
57/206 (coupled to a stub coupler 1002 of a wire 702), the guided wave 1004 then enters the transmitter / receiver device 1006 and is coupled to the cylindrical waveguide or the conductive waveguide. Although the transmitter / receiver device 1006 is shown including a separate waveguide, antenna, cavity resonator, klystron, magnetron, progressive wave tube or other radiation element can be employed to induce a guided wave in the coupler 1002, with or without the separate waveguide.
[0133] In one embodiment, stub coupler 1002 can be constructed entirely of a dielectric material (or other suitable insulating material), without any metallic or conductive materials in it. The stub coupler 1002 can be composed of nylon, Teflon, polyethylene, a polyamide, other plastics or other materials that are non-conductive and are suitable to facilitate the transmission of electromagnetic waves at least in part on an outer surface of these materials. In another embodiment, stub coupler 1002 may include a core that is conductive / metallic and have an outer dielectric surface. Similarly, a transmission medium that is coupled to the stub coupler 1002 to propagate electromagnetic waves induced by the stub coupler 1002 or to provide electromagnetic waves to the stub conductor 1002 can, in addition to being a bare or insulated wire, be constructed entirely of a dielectric material (or other suitable insulating material), without any metallic or conductive materials in it.
Petition 870190094101, of 9/19/2019, p. 64/263
58/206 [0134] It is noted that, although Figure 10A shows that the opening of the transmitter / receiver device 1006 is much larger than the stub coupler 1002, this is not to scale, and in other embodiments the width of the stub 1002 is comparable to or slightly smaller than the hollow waveguide opening. Likewise, this is not shown, but in one embodiment, one end of the coupler 1002 that is inserted into the transmitter / receiver device 1006 tapers downward to reduce reflection and increase coupling efficiencies.
[0135] Prior to coupling to stub coupler 1002, one or more waveguide modes of the guided wave generated by the transmitter / receiver device 1006 may be coupled to stub coupler 1002 to induce one or more wave propagation modes guided wave 1004. The wave propagation modes of the guided wave 1004 may be different from the hollow metal waveguide modes due to the different characteristics of the hollow metal waveguide and the dielectric waveguide. For example, the wave propagation modes of the guided wave 1004 may comprise the fundamental transverse electromagnetic mode (Quasi-TEMoo), where only small electric and / or magnetic fields extend in the direction of propagation, and the electric and magnetic fields extend radially outward from stub coupler 1002 while guided waves propagate along stub coupler 1002. The fundamental transverse electromagnetic mode wave propagation mode may or may not exist within a hollow waveguide. Consequently, the hollow metal waveguide modes that are used by the
Petition 870190094101, of 9/19/2019, p. 65/263
59/206 transmitter / receiver device 1006 are waveguide modes that can be coupled effectively and efficiently in the wave propagation modes of stub coupler 1002.
[0136] It will be recognized that other constructions or combinations of the transmitter / receiver device 1006 and stub coupler 1002 are possible. For example, a stub coupler 1002 'can be placed tangentially or parallel (with or without a gap) with respect to a outer surface of the hollow metal waveguide of the transmitter / receiver device 1006 '(corresponding circuitry not shown) as represented by reference 1000' of Figure 10B. In another embodiment, not shown by reference 1000 ', stub coupler 1002' can be placed inside the hollow metal waveguide of the transmitter / receiver device 1006 'without an axis of stub coupler 1002' being coaxially aligned with a hollow metal waveguide axis of transmitter / receiver device 1006 '. In either of these embodiments, the guided wave generated by the transmitter / receiver device 1006 'can be coupled to a surface of the stub coupler 1002' to induce one or more wave propagation modes of the guided wave 1004 'on the stub coupler 1002' including a fundamental mode (for example, a symmetrical mode) and / or a non-fundamental mode (for example, asymmetric mode).
[0137] In one embodiment, the guided wave 1004 'can propagate partly on the outer surface of stub coupler 1002' and partly on the inside of stub coupler 1002 '. In another modality, the guided wave 1004 'can propagate
Petition 870190094101, of 9/19/2019, p. 66/263
60/206 substantially or completely on the outer surface of stub coupler 1002 '. In still other embodiments, the guided wave 1004 'can propagate substantially or completely within the stub coupler 1002'. In the latter embodiment, the guided wave 1004 'can radiate at one end of the stub coupler 1002' (such as, for example, the tapered end shown in Figure 9) for coupling to a transmission medium, such as a wire 702 of Figure 9.
[0138] It will also be recognized that other constructions of the transmitter / receiver device 1006 are possible. For example, a hollow metal waveguide of a transmitter / receiver device 1006 '' (corresponding circuitry not shown), shown in Figure 10B as reference 1000 '', it can be placed tangentially or parallel (with or without a gap) with respect to an outer surface of a transmission medium, such as, for example, wire 702 of Figure 4 without the use of stub coupler 1002 In this embodiment, the guided wave generated by the transmitter / receiver device 1006 '' can be coupled to a surface of wire 702 to induce one or more modes of wave propagation of a guided wave 908 on wire 702 including a fundamental mode (for example , a symmetric mode) and / or a non-fundamental mode (for example, asymmetric mode). In another embodiment, wire 702 can be positioned within a hollow metal waveguide of a 1006 '' 'transmitter / receiver device (corresponding circuitry not shown) so that an axis of wire 702 is coaxially (or not coaxially) aligned
Petition 870190094101, of 9/19/2019, p. 67/263
61/206 with a hollow metal waveguide axis without the use of stub coupler 1002, see Figure 10B reference 1000 '' '. In this embodiment, the guided wave generated by the transmitter / receiver device 1006 '' can be coupled to a surface of the wire 702 to induce one or more modes of wave propagation of a guided wave 908 on the wire including a fundamental mode (for example, symmetrical mode) and / or a non-fundamental mode (for example, asymmetric mode).
[0139] In the 1000 '' and 1000 '' modalities, for a wire 702 having an insulated outer surface, the guided wave 908 can propagate partly on the outer surface of the insulator and partly on the interior of the insulator. In the embodiments, the guided wave 908 can propagate substantially or completely on the outer surface of the insulator, or substantially or completely within the insulator. In the 1000 '' and 1000 '' modalities, for a wire 702 that is a bare conductor, the guided wave 908 can propagate partly on the outer surface of the conductor and partly inside the conductor. In another embodiment, the guided wave 908 can propagate substantially or completely on the outer surface of the conductor.
[0140] With reference now to Figure 11, a block diagram 1100 is shown illustrating a non-limiting example of a double stub coupler. In particular, a double coupler design is presented for use in a transmission device, such as a transmission device 101 or 102 shown in conjunction with Figure 1. In one embodiment, two or more couplers (such as, for example, 1104 stub couplers
Petition 870190094101, of 9/19/2019, p. 68/263
62/206 and 1106) can be positioned around a wire 1102 to receive the guided wave 1108. In one embodiment, a coupler is sufficient to receive the guided wave 1108. In this case, the guided wave 1108 is coupled to the coupler 1104 and propagates as guided wave 1110. If the field structure of the guided wave 1108 oscillates or waves around the wire 1102 due to the particular guided wave mode (s) or various external factors, then the coupler 1106 it can be placed so that the guided wave 1108 is coupled to the coupler 1106. In some embodiments, four or more couplers can be placed around a portion of the wire 1102, for example, at 90 degrees or another spacing from each other , to receive guided waves that can oscillate or rotate around wire 1102, which were induced in different azimuth orientations or that have non-fundamental or higher modes that, for example, have bumps and / or zeros or other asymmetries that depend on or ientation. However, it will be recognized that there may be fewer or more than four couplers placed around a portion of the wire 1102 without departing from the example modalities.
[0141] It should be noted that although couplers 1106 and 1104 are illustrated as stub couplers, any other of the coupler designs described here, including arc couplers, antenna or horn couplers, magnetic couplers, etc., can also be used . It will also be recognized that while some example embodiments have featured a plurality of couplers around at least a portion of a wire 1102, that plurality of couplers can also be considered
Petition 870190094101, of 9/19/2019, p. 69/263
63/206 as part of a single coupler system having multiple coupler subcomponents. For example, two or more couplers can be manufactured as a single system that can be installed around a wire in a single installation so that the couplers are prepositioned or adjustable in relation to each other (manually or automatically with a controllable mechanism, such as a motor or other actuator) according to the unique system.
[0142] Receivers coupled to couplers 1106 and 1104 can use combination of diversity to combine signals received from both couplers 1106 and 1104 to maximize signal quality. In other embodiments, if one or other of the couplers 1104 and 1106 receives a transmission that is above a predetermined threshold, the receivers can use the selection diversity when deciding which signal to use. Furthermore, although reception by a plurality of couplers 1106 and 1104 is illustrated, transmission by couplers 1106 and 1104 in the same configuration may also occur. In particular, a wide range of multiple input, multiple output (MIMO) transmission and reception techniques can be employed for transmissions where a transmission device, such as a 101 or 102 transmission device shown in conjunction with Figure 1, includes multiple transceivers and multiple couplers.
[0143] It is noted that the graphic representations of waves 1108 and 1110 are presented merely to illustrate the principles that guided wave 1108 induces or else launches

64/206 an 1110 wave in a 1104 coupler. The effective electric and magnetic fields generated as a result of this wave propagation can vary depending on the frequencies used, the design of the coupler 1104, the dimensions and composition of the wire 1102, as well as their surface characteristics, its insulation, if any, the electromagnetic properties of the surrounding environment, etc.
[0144] In relationship now The figure 12, is shown one diagram in blocks 1200 illustrating an modality not limiting in example the of a system in repeaters. In
In particular, a repeater device 1210 is shown for use in a transmission device, such as a transmission device 101 or 102 shown in conjunction with Figure 1. In this system, two couplers 1204 and 1214 can be placed next to a wire 1202 or other transmission means, so that the guided waves 1205 propagating along the wire 1202 are extracted by the coupler 1204 as the wave 1206 (for example as a guided wave), and then are intensified or repeated by the repeater device 1210 and launched as a 1216 wave (for example as a guided wave) on coupler 1214. Wave 1216 can then be launched on wire 1202 and continue to propagate along wire 1202 as a guided wave 1217. In one embodiment, the device Repeater 1210 can receive at least a portion of the power used for intensification or repetition by magnetic coupling with wire 1202, for example, when wire 1202 is a line of power or contains a power-carrying conductor. It should be noted that although couplers 1204 and 1214 are

65/206 illustrated as stub couplers, any other of the coupler designs described herein, including arc couplers, antenna or horn couplers, magnetic couplers, or the like, may also be used.
[0145] In some embodiments, the repeater device 1210 may repeat the transmission associated with wave 1206, and in other embodiments, the repeater device 1210 may include a communications interface 205 that extracts data or other signals from wave 1206 to provide that data or signals to another network and / or one or more other devices such as communication signals 110 or 112 and / or to receive communication signals 110 or 112 from another network and / or one or more other devices and launch the guided wave 1216 having incorporated the 110 or 112 communication signals received. In a repeater configuration, receiver waveguide 1208 can receive wave 1206 from coupler 1204 and transmitter waveguide 1212 can launch guided wave 1216 at coupler 1214 as guided wave 1217. Between receiver waveguide 1208 and the transmitter waveguide 1212, the signal embedded in the guided wave 1206 and / or the guided wave 1216 itself can be amplified to correct signal loss and other inefficiencies associated with guided wave communications, or the signal can be received and processed to extract the data contained there and regenerated for transmission. In one embodiment, the receiver waveguide 1208 can be configured to extract data from the signal, process the data to correct data errors using for example error correction codes, and regenerate an updated signal with the corrected data. The transmitter waveguide 1212 can then
Petition 870190094101, of 9/19/2019, p. 72/263
66/206 transmit the guided wave 1216 with the updated signal incorporated there. In one embodiment, a signal embedded in the guided wave 1206 can be extracted from the transmission and processed for communication with another network and / or one or more other devices via the communications interface 205 as communication signals 110 or 112. Similarly, the signals in
Communication 110 or 112 received by interface in communications 205 can to be inserted in a streaming in guided wave 1216 what is generated and launched on coupler 1214
transmitter waveguide 1212.
[0146] It is noted that although Figure 12 shows guided wave transmissions 1206 and 1216 entering from the left and exiting from the right respectively, this is merely a simplification and is not intended to be a limitation. In other embodiments, the receiving waveguide 1208 and the transmitting waveguide 1212 can also function as transmitters and receivers respectively, allowing the repeater device 1210 to be bidirectional.
[0147] In one embodiment, the repeater device 1210 can be placed in locations where there are discontinuities or obstacles in wire 1202 or other means of transmission. In the case where wire 1202 is a power line, these obstacles may include transformers, connections, electricity poles and other such power line devices. The repeater device 1210 can help guided waves (e.g., surface) to bypass these obstacles on the line and intensify the transmit power at the same time. In other embodiments, a coupler can be used to bypass the
Petition 870190094101, of 9/19/2019, p. 73/263
67/206 obstacle without the use of a repeater device. In this embodiment, both ends of the coupler can be tied or attached to the wire, thus providing a path for the guided wave to move without being blocked by the obstacle. [0148] Now moving on to Figure 13, a 1300 block diagram of a non-limiting example of a bidirectional repeater is illustrated according to several aspects described here. In particular, a bidirectional repeater device 1306 is presented for use in a transmission device, such as a transmission device 101 or 102 shown in conjunction with Figure 1. It should be noted that although couplers are illustrated as couplers of stub, any other of the coupler designs described herein, including bow couplers, antenna or horn couplers, magnetic couplers, or the like, may also be used. The bidirectional repeater 1306 can employ diversity paths in the event that two or more wires or other means of transmission are present. Since guided wave transmissions have different transmission efficiencies and coupling efficiencies for a transmission medium of different types, such as, for example, insulated wires, non-insulated wires or other types of transmission media and others, if exposed to elements, they can be affected by climatic conditions, and other atmospheric conditions, which can be advantageous to transmit selectively in different means of transmission at certain times. In various modalities, the various means of transmission can be designated as primary,
Petition 870190094101, of 9/19/2019, p. 74/263
68/206 secondary, tertiary, etc. regardless of whether that designation indicates a preference for one means of transmission over another.
[0149] In the embodiment shown, the transmission means includes an insulated or non-insulated wire 1302 and an insulated or non-insulated wire 1304 (hereinafter referred to as wires 1302 and 1304, respectively). The repeater device 1306 uses a receiver coupler 1308 to receive a guided wave moving along the wire 1302 and repeats the transmission using the transmitter waveguide 1310 with a guided wave along the wire 1304. In other embodiments, the repeater device 1306 you can switch from wire 1304 to wire 1302 or you can repeat transmissions along the same paths. Repeater device 1306 may include sensors or be in communication with the sensors (or a network management system 1601 depicting in Figure 16A) that indicate conditions that may affect transmission. Based on the feedback received from the sensors, the repeater device 1306 can make the determination on whether to maintain the transmission along the same wire or transfer the transmission to the other wire.
[0150] Moving now to Figure 14, a block diagram 1400 is illustrated illustrating a non-limiting example of a bidirectional repeater system. In particular, a bidirectional repeater system is presented for use in a transmission device, such as a transmission device 101 or 102 shown in conjunction with Figure 1. The bidirectional repeater system includes
Petition 870190094101, of 9/19/2019, p. 75/263
69/206 waveguide coupling devices 1402 and 1404 that receive and transmit transmissions from other coupling devices located in a distributed antenna system or backhaul system.
[0151] In various embodiments, the waveguide coupling device 1402 can receive a transmission from another waveguide coupling device, wherein the transmission has a plurality of subcarriers. The diplexer 1406 can separate the transmission from other transmissions and direct the transmission to the low noise amplifier (LNA) 1408. A frequency mixer 1428, with the help of a local oscillator 1412, can reduce the transmission (which is in the band millimeter wave or about 38 GHz in some modes) to a lower frequency, such as a cellular band (—1.9 GHz) for a distributed antenna system, native frequency or other frequency for a system backhaul. An extractor (or demultiplexer) 1432 can extract the signal in a subcarrier and direct the signal to an output component 1422 for amplification, buffering or optional isolation by the power amplifier 1424 for coupling to the 205 communications interface. communications 205 can further process the signals received from the power amplifier 1424 or transmit these signals over a wired or wireless interface to other devices, such as a base station, mobile devices, a building, etc. For signals that are not being extracted at that location, the 1432 extractor can redirect
Petition 870190094101, of 9/19/2019, p. 76/263
70/206 same for another frequency mixer 1436, where the signals are used to modulate a carrier wave generated by the local oscillator 1414. The carrier wave, with its subcarriers, is directed to a power amplifier (PA) 1416 and is retransmitted by waveguide coupling device 1404 to another system via diplexer 1420.
[0152] An LNA 1426 can be used to amplify, buffer or isolate signals that are received by the communication interface 205 and then send the signal to a multiplexer 1434 that interleaves the signal with signals that were received from the waveguide coupling 1404. The signals received from the coupling device 1404 were divided by the diplexer 1420 and then passed through the LNA 1418 and reduced in terms of frequency by the frequency mixer 1438. When the signals are combined by the multiplexer 1434, their frequency is increased by the frequency mixer 1430 and then they are intensified by the PA 1410 and transmitted to another system by the waveguide coupling device 1402. In one embodiment, the bidirectional repeater system can be merely a repeater without the output device 1422. In this mode, the multiplexer 1434 would not be used and the signals from LNA 1418 would be directed to for mixer 1430 as previously described. It will be recognized that, in some embodiments, the bidirectional repeater system can also be implemented using two separate and separate unidirectional repeaters. In an alternative modality, a
Petition 870190094101, of 9/19/2019, p. 77/263
71/206 bidirectional repeater system can also be an intensifier or carry out retransmissions without reduction and increase. In fact, in the example mode, retransmissions can be based on the reception of a signal or guided wave and on the execution of processing or reformulation, filtering and / or amplification of any signal or guided wave, before the retransmission of the signal or the guided wave .
[0153] Referring now to Figure 15, a block diagram 1500 is shown illustrating a non-limiting example of a guided wave communications system. This diagram represents an exemplary environment in which a guided wave communication system can be used, such as, for example, the guided wave communication system presented in conjunction with Figure 1.
[0154] To provide network connectivity to additional base station devices, a backhaul network that connects communication cells (for example, microcells and macrocells) to network devices on a primary network expands accordingly. Similarly, to provide network connectivity to a distributed antenna system, an extended communication system that connects base station devices and their distributed antennas is desirable. A guided wave communication system 1500 as shown in Figure 15 can be provided to allow alternative, increased or additional network connectivity, and a waveguide coupling system can be provided to transmit and / or receive guided wave communications ( surface wave) in a transmission medium, such as a wire, that operates as a transmission line
Petition 870190094101, of 9/19/2019, p. 78/263
72/206 single wire (for example, a utility line) that can be used as a waveguide and / or otherwise operate to guide the transmission of an electromagnetic wave.
[0155] The guided wave communication system 1500 may comprise a first instance of a distribution system 1550 that includes one or more base station devices (e.g. base station device 1504) that are communicably coupled in a central office 1501 and / or a macrocell location 1502. The base station device 1504 can be connected via a wired (eg fiber and / or cable) or wireless (eg wireless microwave) connection ) to macrocell location 1502 and central office 1501. A second instance of the 1560 distribution system can be used to provide wireless voice and data services to the mobile device 1522 and to residential and / or commercial establishments 1542 (referred to herein as establishments 1542). The system
1500 can have additional instances of the distribution systems 1550 and 1560 to provide voice and / or data services to mobile devices 1522-1524 and establishments 1542 as shown in Figure 15.
[0156] Macroscells, such as macrocell location 1502, may have dedicated connections to a 1504 base station and mobile network device or may share and / or use another connection. The central office
1501 can be used to distribute media content and / or provide Internet service provider (ISP) services to 1522-1524 mobile devices and 1542 establishments. Headquarters 1501 can receive media content from
Petition 870190094101, of 9/19/2019, p. 79/263
73/206 a constellation of satellites 1530 (one of which is shown in Figure 15) or other sources of content, and distribute that content to mobile devices 1522-1524 and establishments 1542 via the first and second instances of the distribution system 1550 and 1560. Head office 1501 can also be coupled communicatively to the Internet 1503 to provide Internet data services to mobile devices 15221524 and establishments 1542.
[0157] The base station device 1504 can be mounted on, or connected to, the electricity pole 1516. In other embodiments, the base station device 1504 can be located near transformers and / or other locations located near a power line. The base station device 1504 can facilitate connectivity to a mobile network for mobile devices 1522 and 1524. Antennas 1512 and 1514, mounted on or adjacent to electricity poles 1518 and 1520, respectively, can receive signals from the base station 1504 and transmit these signals to mobile devices 1522 and 1524 over a much larger area than if antennas 1512 and 1514 were located on, or adjacent to, base station device 1504.
[0158] It is noted that Figure 15 shows three electricity poles, in each instance of the distribution systems 1550 and 1560, with a base station device, for the sake of simplicity. In other embodiments, the 1516 electricity pole may have more power station devices
Petition 870190094101, of 9/19/2019, p. 80/263
74/206 base, and more electricity poles with distributed antennas and / or connections linked to 1542 establishments.
[0159] A transmission device 1506, such as transmission device 101 or 102 shown in conjunction with Figure 1, can transmit a signal from the base station device 1504 to antennas 1512 and 1514 over the line (s ) of power or utilities that connect electricity poles 1516, 1518 and 1520. To transmit the signal, the radio source and / or the transmission device 1506 convert the signal to a higher value (for example, by mixing frequency) of the base station device 1504 or else convert the signal from the base station device 1504 to a microwave band signal, and the transmission device 1506 launches a propagating microwave band wave as a guided wave moving along the utility line or other wire as described in previous modalities. At electricity pole 1518, another transmission device 1508 receives the guided wave (and optionally can amplify it as needed or desired or operate as a repeater to receive and regenerate it) and sends it as a guided wave on the service line public or other wire. The transmission device 1508 can also extract a signal from the microwave wave guided wave and reduce its frequency or convert it to its original cellular band frequency (for example, 1.9 GHz or other defined cellular frequency) or another cellular (or non-cellular) band frequency. A 1512 antenna can wirelessly transmit the reduced signal to the
Petition 870190094101, of 9/19/2019, p. 81/263
75/206 mobile device 1522. The process can be repeated by the transmission device 1510, the antenna 1514 and the mobile device 1524, as necessary or desirable.
[0160] Transmissions from mobile devices 1522 and 1524 can also be received by antennas 1512 and 1514, respectively. The transmission devices 1508 and 1510 can increase or convert the cell band signals into a microwave band and transmit the signals as guided wave transmissions (for example, surface wave or other electromagnetic wave) over the line (s) s) power to the base station device 1504.
[0161] The media content received by the central office 1501 can be provided to the second instance of the distribution system 1560 via the base station device 1504 for distribution to the mobile devices 1522 and establishments 1542. The transmission device 1510 can be linked to 1542 establishments via one or more wired connections or a wireless interface. The one or more wired connections may include, without limitation, a power line, a coaxial cable, a fiber cable, a twisted pair cable, a guided wave transmission medium or other suitable wired media for content distribution media and / or to provide Internet services. In an example embodiment, the wired connections of the 1510 transmitting device can be communicatively coupled to one or more very high bit rate digital subscriber line (VDSL) modems located on one or more service area interfaces (SAI) - not shown) correspondents or bases, each SAI or base providing services to a portion of the
Petition 870190094101, of 9/19/2019, p. 82/263
76/206 establishments 1542. VDSL modems can be used to selectively distribute media content and / or provide Internet services to gateway (not shown) located in 1542 establishments. SAIs or bases can also be communicatively coupled at 1542 establishments by a wired medium, such as a power line, a coaxial cable, a fiber cable, a twisted pair cable, a guided wave transmission medium or other suitable wired means. In other example embodiments, the transmission device 1510 can be communicatively coupled directly to establishments 1542 without intermediate interfaces, such as, for example, SAIs or bases.
[0162] In another example, the 1500 system can employ diversity paths, where two or more utility lines or other wires are threaded between the electricity poles 1516, 1518 and 1520 (for example, two or more wires between posts 1516 and 1520), and redundant transmissions from the base station / macrocell site 1502 are transmitted as waves guided by the surface of utility lines or other wires. Utility lines or other wires can be insulated or non-insulated, and depending on the environmental conditions that cause transmission losses, the coupling devices can selectively receive signals from utility lines or other insulated or non-insulated wires. The selection can be based on measurements of the signal-to-noise ratio of the wires or based on certain climatic / environmental conditions (for example, humidity detectors, weather forecasts,
Petition 870190094101, of 9/19/2019, p. 83/263
77/206 etc.). The use of diversity paths with the 1500 system can allow for alternative routing capabilities, load balancing, increased load handling, simultaneous synchronous or bidirectional communications, broad spectrum communications, etc.
[0163] It is noted that the use of transmission devices 1506, 1508 and 1510 in Figure 15 serves merely as an example and that, in other modalities, other uses are possible. For example, transmission devices can be used in a backhaul communication system, providing network connectivity to base station devices. Transmission devices 1506, 1508 and 1510 can be used in many circumstances where it is desirable to transmit wave communications guided by a wire, isolated or non-isolated. Transmission devices 1506, 1508 and 1510 are improvements over other coupling devices due to non-contact or limited physical and / or electrical contact with wires that can carry high voltages. The transmission device can be located away from the wire (for example, away from the wire) and / or located on the wire as long as it is not electrically in contact with the wire, since the dielectric acts as an insulator, allowing an economical installation , easy and / or less complex. However, as previously noted, conductive or non-dielectric couplers can be used, for example, in configurations where the wires correspond to a telephone network, cable television network, broadband data service, communications system
Petition 870190094101, of 9/19/2019, p. 84/263
78/206 optical fiber or other network employing low voltages or having isolated transmission lines.
[0164] It is further noted that, although the base station device 1504 and the macrocell location 1502 are illustrated in one embodiment, other network configurations are also possible. For example, devices, such as access points or other wireless ports, can be used in a similar way to extend the range of other networks, such as a wireless local area network, a personal wireless area network or another wireless network that operates according to a communication protocol, such as an 802.11 protocol, WIMAx protocol, Ultra-Broadband protocol, Bluetooth protocol, Zigbee protocol or other wireless protocol.
[0165] With reference now to Figures 16A & 16B, the block diagrams illustrating a non-limiting example of a system for managing a mains communication system are shown. Considering Figure 16A, a waveguide system 1602 is presented for use in a guided wave communications system, such as, for example, the system presented in conjunction with Figure 15. The waveguide system 1602 can comprise sensors 1604, a power management system 1605, a transmission device 101 or 102 that includes at least one communication interface 205, a transceiver 210 and a coupler 220.
[0166] The waveguide system 1602 can be coupled to a power line 1610 to facilitate guided wave communications according to modalities described in the disclosure under discussion. In an example embodiment, the
Petition 870190094101, of 9/19/2019, p. 85/263
79/206 transmission 101 or 102 includes coupler 220 to induce electromagnetic waves on a surface of the power line 1610 that propagates longitudinally along the surface of the power line 1610 as described in the disclosure under discussion. The transmission device 101 or 102 can also serve as a repeater for retransmitting electromagnetic waves on the same power line 1610 or for routing electromagnetic waves between power lines 1610 as shown in Figures 12 and 13.
[0167] Transmission device 101 or 102 includes transceiver 210 configured to, for example, convert a signal operating in a range of original frequency to electromagnetic waves operating in, displaying or associated with a carrier frequency to a higher value. propagates along a coupler to induce corresponding guided electromagnetic waves that propagate along a surface of the 1610 power line. A carrier frequency can be represented by a central frequency having upper and lower cutoff frequencies that define the bandwidth electromagnetic waves. Power line 1610 can be a wire (for example, monofilament or multifilament) having a conductive surface or insulated surface. Transceiver 210 can also receive signals from coupler 220 and convert electromagnetic waves operating at a carrier frequency to signals at their original frequency to a lower value.
[0168] Signals received by the communications interface 205 of the transmission device 101 or 102 for conversion
Petition 870190094101, of 9/19/2019, p. 86/263
80/206 for a higher value may include, without limitation, signals provided by a central office 1611 over a wired or wireless interface of the communications interface 205, a base station 1614 over a wired or wireless interface of the communications interface 205 , wireless signals transmitted by mobile devices 1620 to base station 1614 for delivery via the wired or wireless interface of communications interface 205, signals provided by communication devices in building 1618 via the wired or wireless interface of communications interface 205, and / or wireless signals provided to the communications interface 205 by mobile devices 1612 while roaming in a wireless communication range of the communications interface 205. In modalities where the waveguide system 1602 functions as a repeater, as shown in Figures 12 and 13, the communications interface 205 may or may not be included in the waveguide system 1602.
[0169] Electromagnetic waves propagating along the surface of the 1610 power line can be modulated and formatted to include data packets or frames that include a data payload and also include networking information (such as, for example, header information for identification of one or more target waveguide systems 1602). Networking information can be provided by the waveguide system 1602 or a source device, such as central office 1611, base station 1614, mobile devices 1620 or devices in building 1618, or a combination of the same. In addition, modulated electromagnetic waves can include error correction data to mitigate
Petition 870190094101, of 9/19/2019, p. 87/263
81/206 signal disturbances. Networking information and error correction data can be used by a 1602 target waveguide system to detect transmissions directed to it, and for conversion to a lower value and processing with data correction data transmissions. errors that include voice and / or data signals directed to recipient communication devices communicatively coupled to the destination waveguide system 1602.
[0170] With respect now to the 1604 sensors of the 1602 waveguide system, the 1604 sensors may comprise one or more between a temperature sensor 1604a, a disturbance detection sensor 1604b, a loss of energy sensor 1604c, a sensor noise sensor 1604d, a vibration sensor 1604e, an environmental sensor (eg climatic conditions) 1604f and / or an image sensor 1604g. The temperature sensor 1604a can be used to measure ambient temperature, a temperature of the transmission device 101 or 102, a temperature of the power line 1610, temperature differentials (for example, compared to a setpoint or baseline , between the transmission device 101 or 102 and 1610, etc.), or any combination thereof. In one embodiment, the temperature metric can be collected and reported periodically to a network management system 1601 via base station 1614.
[0171] The disturbance detection sensor 1604b can take measurements on the power line 1610 to detect disturbances, such as signal reflections, which may indicate the presence of a disturbance downstream that
Petition 870190094101, of 9/19/2019, p. 88/263
82/206 can prevent the propagation of electromagnetic waves on the 1610 power line. A signal reflection can represent a distortion resulting from, for example, a wave
electromagnetic transmitted on the line power 1610 fur device in streaming 101 or 102 that reflects at totality or in part again on the device in streaming 101 or 102 from a line disturbance
of power 1610 located downstream from the transmission device 101 or 102.
[0172] Signal reflections can be caused by obstructions in the 1610 power line. For example, a tree branch can cause electromagnetic wave reflections when the tree branch is located in the 1610 power line, or is close to the line. power rating 1610, which can cause a discharge to the crown. Other obstructions that can cause electromagnetic wave reflections may include, without limitation, an object that has become entangled in the 1610 power line (for example, clothing, a shoe wrapped around a 1610 power line with a laces, etc.), a corroded buildup on the 1610 power line or an ice buildup. The mains components can also prevent or obstruct the propagation of electromagnetic waves on the surface of the 1610 power lines. Illustrations of mains components that can cause signal reflections include, without limitation, a transformer and a joint for connecting lines united power. A sharp angle on the 1610 power line can also cause electromagnetic wave reflections.
Petition 870190094101, of 9/19/2019, p. 89/263
83/206 [0173] The disturbance detection sensor 1604b may comprise a circuit for comparing magnitudes of electromagnetic wave reflections with original electromagnetic wave magnitudes transmitted by the transmission device 101 or 102 to determine how much of a disturbance downstream in the power line 1610 mitigates transmissions. The disturbance detection sensor 1604b may further comprise a spectral analyzer circuit for performing spectral analysis on the reflected waves. The spectral data generated by the spectral analyzer circuit can be compared with spectral profiles via pattern recognition, a specialized system, curve fitting, matched filtering or other artificial intelligence technique, classification or comparison to identify a type of disturbance based on, for example, in the spectral profile that most closely corresponds to the spectral data. Spectral profiles can be stored in a disturbance detection sensor 1604b memory or can be remotely accessible by the disturbance detection sensor 1604b. The profiles can comprise spectral data that model different disturbances that can be found on power lines 1610 to allow disturbance detection sensor 1604b to identify disturbances locally. A disturbance identification, if known, can be reported to network management system 1601 via base station 1614. Disturbance detection sensor 1604b can also use transmission device 101 or 102 to transmit electromagnetic waves as test to determine a
Petition 870190094101, of 9/19/2019, p. 90/263
84/206 round trip time for electromagnetic wave reflection. The round trip time measured by the disturbance detection sensor 1604b can be used to calculate a distance traveled by the electromagnetic wave to a point where reflection occurs, which allows the disturbance detection sensor 1604b to calculate a distance between the device transmission 101 or 102 and the downstream disturbance on the power line 1610.
[0174] The calculated distance can be reported to the network management system 1601 via the base station 1614. In one embodiment, the location of the waveguide system 1602 on the power line 1610 can be known from the management system network 1601, which network management system 1601 can use to determine a location of the disturbance on power line 1610 based on a known topology of the electrical network. In another embodiment, the waveguide system 1602 can provide its location to the network management system 1601 to assist in determining the location of the disturbance on the 1610 power line. The location of the waveguide system 1602 can be obtained by the system waveguide 1602 from a pre-programmed location of the waveguide system 1602 stored in a waveguide system memory 1602, or the waveguide system 1602 can determine its location using a GPS receiver (not shown) included in the 1602 waveguide system.
[0175] The 1605 power management system supplies power to the components mentioned above in the system
Petition 870190094101, of 9/19/2019, p. 91/263
85/206 waveguide 1602. Power management system 1605 can receive energy from solar cells, or from a transformer (not shown) coupled to power line 1610, or by inductive coupling to power line 1610 or another line close power. The 1605 power management system may also include a backup battery and / or a supercapacitor or other capacitor circuit to supply the 1602 waveguide system with temporary power. The 1604c power loss sensor can be used to detect when the 1602 waveguide system has a loss of power condition and / or the occurrence of some other malfunction. For example, the 1604c power loss sensor can detect when there is a loss of power due to defective solar cells, an obstruction in the solar cells that causes a malfunction, loss of power in the 1610 power line, and / or when the backup power system does not work due to the expiration of a backup battery or a detectable defect in a supercapacitor. When a malfunction and / or power loss occurs, the power loss sensor 1604c can notify the network management system 1601 through the base station 1614.
[0176] The noise sensor 1604d can be used to measure noise in the power line 1610 which can adversely affect the transmission of electromagnetic waves in the power line 1610. The noise sensor 1604d may experience unexpected electromagnetic interference, noise bursts or other disturbance sources that can interrupt the reception of modulated electromagnetic waves on a surface of a
Petition 870190094101, of 9/19/2019, p. 92/263
86/206 power line 1610. A burst of noise can be caused by, for example, a discharge in the crown or another source of noise. The noise sensor 1604d can compare the measured noise with a noise profile obtained by the 1602 waveguide system from an internal noise profile database or from a remotely located database that stores noise profiles via recognition of patterns, a specialized system, curves adjustment, corresponding filtering or other artificial intelligence technique, classification or comparison. From the comparison, the noise sensor 1604d can identify a noise source (for example, discharge in the crown or other) based, for example, on the noise profile that provides the closest match to the measured noise. The 1604d noise sensor can also detect how noise affects transmissions by measuring the transmission metric, such as bit error rate, packet loss rate, oscillation, packet retransmission requests, etc. The noise sensor 1604d can report to the network management system 1601 through base station 1614 the identity of noise sources, their time of occurrence and transmission metric, among other things.
[0177] The vibration sensor 1604e can include accelerometers and / or gyroscopes to detect 2D or 3D vibrations in the 1610 power line. Vibrations can be compared with vibration profiles that can be stored locally in the 1602 waveguide system or obtained using the 1602 waveguide system of a remote database via pattern recognition, a specialized system, curve fitting, matching filtering or other technique
Petition 870190094101, of 9/19/2019, p. 93/263
87/206 artificial intelligence, classification or comparison. The vibration profiles can be used, for example, to distinguish trees that have fallen due to gusts of wind based, for example, on the vibration profile that provides the closest match to the measured vibrations. The results of this analysis can be reported by the vibration sensor 1604e to the network management system 1601 through the base station 1614.
[0178] The 1604f environmental sensor can include a barometer for measuring atmospheric pressure, ambient temperature (which can be provided by temperature sensor 1604a), wind speed, humidity, wind direction and atmospheric precipitation, among other things. The 1604f environmental sensor can collect raw information and process that information by comparing it with environmental profiles that can be obtained from a 1602 waveguide system memory or a remote database to predict weather conditions before they arise via pattern recognition, a specialized system, a knowledge-based system or other modeling technique and forecasting of artificial intelligence, classification or other climatic conditions. The 1604f environmental sensor can report raw data as well as its analysis to the 1601 network management system.
[0179] The 1604g image sensor can be a digital camera (for example, a charged attached device or CCD imager, infrared camera, etc.) for capturing images close to the 1602 waveguide system. The image sensor 1604g can include an electromechanical mechanism
Petition 870190094101, of 9/19/2019, p. 94/263
88/206 to control the movement (for example, effective position or zooms / focal points) of the camera for inspection of the 1610 power line from multiple perspectives (for example, top surface, bottom surface, left surface, right surface, and so on) against). Alternatively, the 1604g image sensor can be designed so that no electromechanical mechanism is needed to obtain multiple perspectives. The collection and retrieval of image data generated by the 1604g image sensor can be controlled by the 1601 network management system, or they can be autonomously collected and reported by the 1604g image sensor to the 1601 network management system.
[0180] Other sensors that may be suitable for collecting telemetry information associated with the waveguide system 1602 and / or power lines 1610 for the purpose of detecting, predicting and / or mitigating disturbances that may prevent the spread of electromagnetic wave transmissions on power lines 1610 (or any other form of electromagnetic wave transmission medium) can be used by the 1602 waveguide system.
[0181] With reference now to Figure 16B, block diagram 1650 illustrates a non-limiting example of a system for managing an electrical network 1653 and a communication system 1655 there incorporated or associated therewith according to various aspects here described. Communication system 1655 comprises a plurality of waveguide systems 1602 coupled to power lines 1610
Petition 870190094101, of 9/19/2019, p. 95/263
89/206 of the 1653 electrical network. At least a portion of the 1602 waveguide systems used in the 1655 communication system can be in direct communication with a 1614 base station and / or the 1601 network management system. waveguide 1602 not directly connected to a base station 1614 or network management system 1601 can engage in communication sessions with a base station 1614 or network management system 1601 through other guidance systems downstream waveform 1602 connected to a base station 1614 or network management system 1601.
[0182] The network management system 1601 can be communicatively coupled to the equipment of a public utility company 1652 and to the equipment of a communications service provider 1654 to provide each entity with state information associated with the 1653 electrical network and the communication system 1655, respectively. Network management system 1601, utility company equipment 1652 and communications service provider 1654 can access communication devices used by utility company 1656 personnel and / or communication devices used by service provider personnel 1658 communications services for the purpose of providing status information and / or for directing these personnel in the management of the 1653 electrical network and / or the 1655 communication system.
[0183] Figure 17A illustrates a flowchart of a non-limiting example of a 1700 method for the detection and mitigation of disturbances occurring on a network
Petition 870190094101, of 9/19/2019, p. 96/263
90/206 of communication of the systems of Figures 16A & 16B. Method 1700 can begin with step 1702 where a 1602 waveguide system transmits and receives messages embedded in, or as part of, modulated electromagnetic waves or other types of electromagnetic waves moving along a surface of a power line 1610. Messages can be voice messages, streaming video and / or other data / information exchanged between communication devices communicatively coupled to the 1655 communication system. In step 1704, sensors 1604 of the waveguide system 1602 can collect data detection. In one embodiment, the detection data can be collected in step 1704 before, during or after the transmission and / or reception of messages in step 1702. In step 1706, the waveguide system 1602 (or the sensors 1604 themselves) can determine from the detection data an actual or expected occurrence of a disturbance in the 1655 communication system that may affect communications originating from (for example, transmitted by) or received by the 1602 waveguide system. The waveguide system 1602 (or 1604 sensors) can process temperature data, signal reflection data, energy loss data, noise data, vibration data, environmental data or any combination thereof to make this determination. The waveguide system 1602 (or sensors 1604) can also detect, identify, estimate or predict the source of the disturbance and / or its location in the 1655 communication system. If a disturbance is not detected / identified or predicted / estimated in the step 1708, the waveguide system
Petition 870190094101, of 9/19/2019, p. 97/263
91/206
1602 can proceed to step 1702 where it continues to transmit and receive messages embedded in, or as part of, modulated electromagnetic waves moving along a surface of the 1610 power line. [0184] If, in step 1708, it is detected / identified or predicted / estimated the occurrence of a disturbance, the waveguide system 1602 proceeds to step 1710 to determine whether the disturbance adversely affects (or, alternatively, may adversely affect or the extent to which it may adversely affect) the transmission or reception of messages in the 1655 communication system. In one embodiment, a duration threshold and an occurrence frequency threshold can be used in step 1710 to determine when a disturbance adversely affects communications in the 1655 communication system. For purposes of illustration only , it is assumed that a duration threshold is set to 500 ms, while an occurrence frequency threshold is defined for 5 disturbances occurring over an observation period of 10 s. Thus, a disturbance lasting more than 500 ms will trigger the duration threshold. In addition, any disturbance occurring more than 5 times in a 10 s time interval will trigger the occurrence frequency threshold.
[0185] In one embodiment, a disturbance can be considered to adversely affect the signal integrity in 1655 communication systems when only the duration threshold is exceeded. In another embodiment, a disturbance can be considered to adversely affect signal integrity in 1655 communication systems when both the duration threshold and the
Petition 870190094101, of 9/19/2019, p. 98/263
92/206 occurrence are exceeded. The latter modality is thus more conservative than the previous modality regarding the classification of disturbances that adversely affect the signal integrity in the 1655 communication system. It will be recognized that many other algorithms and associated parameters and thresholds can be used in step 1710 according to modalities example.
[0186] Again in relation to method 1700, if in step 1710 the disturbance detected in step 1708 does not meet the condition for adversely affected communications (for example, it does not exceed the duration threshold or the frequency threshold of occurrence), the waveguide 1602 can proceed to step 1702 and continue processing messages. For example, if the disturbance detected in step 1708 has a duration of 1 ms with a single occurrence over a 10 s time period, then no threshold will be exceeded. Consequently, this disturbance can be considered to have a nominal effect on the signal integrity in the 1655 communication system and thus will not be signaled as a disturbance requiring mitigation. Although not signaled, the occurrence of the disturbance, its time of occurrence, its frequency of occurrence, spectral data and / or other useful information can be reported to the network management system 1601 as telemetry data for monitoring purposes.
[0187] Again in relation to step 1710, if on the other hand the disturbance satisfies the condition for adversely affected communications (for example, exceeding one or both thresholds), the 1602 waveguide system can proceed to
Petition 870190094101, of 9/19/2019, p. 99/263
93/206 step 1712 and report the incident to the network management system 1601. The report can include raw detection data collected by sensors 1604, a description of the disturbance if known by the waveguide system 1602, a time of occurrence of disturbance, a frequency of occurrence of the disturbance, a location associated with the disturbance, parameter readings, such as, for example, bit error rate, packet loss rate, retransmission requests, oscillation, latency, and so on. If the disturbance is based on a prediction of one or more sensors in the 1602 waveguide system, the report can include an expected type of disturbance and, if predictable, an expected time of occurrence of the disturbance and an expected frequency of occurrence of the disturbance predicted when the forecast is based on historical detection data collected by sensors 1604 of the 1602 waveguide system.
[0188] In step 1714, the network management system
1601 can determine a mitigation, bypass or correction technique, which can include directing the waveguide system 1602 to reroute traffic to circumvent the disturbance if the location of the disturbance can be determined. In one embodiment, the waveguide coupling device 1402 detecting the disturbance can direct a repeater, such as that shown in Figures 13 and 14, to connect the waveguide system
1602 between a primary power line affected by the disturbance and a secondary power line to allow the 1602 waveguide system to route traffic again
Petition 870190094101, of 9/19/2019, p. 100/263
94/206 to a different transmission medium and avoid disturbance. In a mode where the waveguide system 1602 is configured as a repeater, the waveguide system 1602 itself can re-route traffic between the primary power line and the secondary power line. It is further noted that for bidirectional communications (for example, full or semi-duplex communications), the repeater can be configured to re-route traffic from the secondary power line back to the primary power line for processing by the 1602 waveguide system.
[018 9] In another embodiment, the waveguide system 1602 can redirect traffic by instructing a first repeater located upstream of the disturbance and a second repeater located downstream of the disturbance to redirect traffic from a primary power line temporarily to a secondary power line and again to the primary power line in a way that avoids disturbance. It is further noted that for bidirectional communications (for example, full or semi-duplex communications), repeaters can be configured to re-route traffic from the secondary power line back to the primary power line.
[0190] To avoid interrupting existing communication sessions occurring on a secondary power line, the network management system 1601 can direct the waveguide system 1602 to instruct the repeater (s) to use ( in) unused time range (s) and / or frequency band (s) of the secondary power line for redirecting data traffic and / or
Petition 870190094101, of 9/19/2019, p. 101/263
95/206 voice away from the primary power line to circumvent the disturbance.
[0191] In step 1716, while traffic is being re-routed to avoid disruption, network management system 1601 can notify utility company equipment 1652 and / or communications service provider 1654 equipment, which in turn can notify the personnel of the utility company 1656 and / or the personnel of the communications service provider 1658 regarding the detected disturbance and its location, if known. Field personnel from either party can assist in resolving the disturbance at a particular location in the disturbance. After removal or mitigation of disturbance by utility personnel and / or communications service provider personnel, these personnel can notify their respective companies and / or the 1601 network management system using field equipment (for example , a laptop, smartphone, etc.) communicatively coupled to the network management system 1601, and / or equipment of the utility company and / or the communications service provider. The notification may include a description of how the disturbance was mitigated and any changes to the 1610 power lines that could change a topology of the 1655 communication system.
[0192] After the disturbance has been resolved (as determined in decision 1718), network management system 1601 can target waveguide system 1602 at step 1720 to restore the previous routing configuration used
Petition 870190094101, of 9/19/2019, p. 102/263
96/206 by the 1602 waveguide system or to route traffic according to a new routing configuration if the restoration strategy used to mitigate the disturbance has resulted in a new 1655 communication system network topology. waveguide system 1602 can be configured to monitor disturbance mitigation by transmitting test signals on power line 1610 to determine when the disturbance has been removed. After the waveguide system 1602 detects an absence of disturbance, it can autonomously restore its routing configuration without assistance from the 1601 network management system if it is determined that the 1655 communication system's network topology has not changed, or you can use a new routing configuration that adapts to a new detected network topology.
[0193] Figure 17B illustrates a flowchart of a non-limiting example of a 1750 method for the detection and mitigation of disturbances occurring in a communication network of the system of Figures 16A and 16B. In one embodiment, method 1750 can begin with step 1752 where a network management system 1601 receives from the utility company 1652 equipment or the communications service provider 1654 equipment maintenance information associated with a maintenance plan. The network management system 1601 can, in step 1754, identify the maintenance activities to be performed during the maintenance plan from the maintenance information. From these activities, the 1601 network management system can detect a
Petition 870190094101, of 9/19/2019, p. 103/263
97/206 maintenance disruption (eg planned replacement of a power line 1610, planned replacement of a waveguide system 1602 on power line 1610, planned reconfiguration of power lines 1610 on mains 1653, etc.) ).
[0194] In another embodiment, the network management system 1601 can receive in step 1755 telemetry information from one or more waveguide systems 1602. The telemetry information may include, among other things, an identity of each guidance system. wave 1602 submitting telemetry information, measurements made by sensors 1604 of each waveguide system 1602, information related to predicted, estimated or actual disturbances detected by sensors 1604 of each waveguide system 1602, location information associated with each 1602 waveguide system, an estimated location of a detected disturbance, an identification of the disturbance, and so on. The network management system 1601 can determine from the telemetry information a type of disturbance that can be adverse to waveguide operations, to the transmission of electromagnetic waves along the wire surface, or both. The network management system 1601 can also use telemetry information from multiple waveguide systems 1602 to isolate and identify the disturbance. In addition, the network management system 1601 can request telemetry information from waveguide systems 1602 near an affected waveguide system 1602 to triangulate a location of the
Petition 870190094101, of 9/19/2019, p. 104/263
98/206 disturbance and / or validate a disturbance identification by receiving similar telemetry information from other 1602 waveguide systems.
[0195] In yet another modality, the network management system 1601 can receive in step 1756 a report of unplanned activities by the field maintenance personnel. Unplanned maintenance can occur as a result of field calls that are unforeseen or as a result of unexpected field problems discovered during field calls or planned maintenance activities. The activity report can identify changes in a 1653 electrical topology configuration resulting from field personnel attending to problems discovered in the 1655 communication system and / or the 1653 electrical network, changes in one or more 1602 waveguide systems (such as , for example, replacement or repair), mitigation of disturbances, if any, and so on.
[0196] In step 1758, network management system 1601 can determine from reports received in accordance with steps 1752 to 1756 whether a disturbance will occur based on a maintenance plan, or whether a disturbance has occurred or is expected occur based on telemetry data, or if a disturbance occurred due to unforeseen maintenance identified in a field activity report. From any of these reports, the network management system 1601 can determine whether a detected or predicted disturbance requires re-routing traffic through waveguide systems
Petition 870190094101, of 9/19/2019, p. 105/263
99/206
1602 affected or other 1602 waveguide systems of the 1655 communication system.
[0197] When a disturbance is detected or predicted in step 1758, network management system 1601 can proceed to step 17 60 where it can direct one or more waveguide systems 1602 to reroute traffic to circumvent the disturbance . When the disturbance is permanent due to a permanent topology change in the 1653 power grid, the network management system 1601 can proceed to step 1770 and skip steps 1762, 1764, 1766 and 1772. In step 1770, the management system network adapter 1601 can target one or more waveguide systems 1602 to use a new routing configuration that adapts to the new topology. However, when the disturbance has been detected from telemetry information provided by one or more waveguide systems 1602, the network management system 1601 can notify maintenance personnel from utility company 1656 or the service provider. 1658 communications of a location of the disturbance, a type of disturbance, if known, and related information that may be useful for such personnel to mitigate the disturbance. When a disturbance is expected due to maintenance activities, the network management system 1601 can direct one or more waveguide systems 1602 to reconfigure traffic routes in a given plan (consistent with the maintenance plan) to avoid disturbances caused maintenance activities during the maintenance plan.
Petition 870190094101, of 9/19/2019, p. 106/263
100/206 [0198] Returning to step 1760 again and after its completion, the process can continue with step 1762. In step 17 62, network management system 1601 can monitor when the disturbance (or disturbances) has been mitigated by personnel field. The mitigation of a disturbance can be detected in step 1762 by analyzing field reports submitted to the network management system 1601 by field personnel on a communications network (for example, cellular communication system) using field equipment (for example, a laptop or computer / portable device). If field personnel have reported that a disturbance has been mitigated, network management system 1601 can proceed to step 1764 to determine from the field report whether a topology change was required to mitigate the disturbance. A topology change may include re-routing a 1610 power line, reconfiguring a 1602 waveguide system to use a different 1610 power line, or using an alternate link to ignore the disturbance, and so on. onwards. If a topology change has occurred, the network management system 1601 can target in step 1770 one or more waveguide systems 1602 to use a new routing configuration that adapts to the new topology.
[0199] If, however, a topology change has not been reported by field personnel, the network management system 1601 can proceed to step 17 66 where it can direct one or more waveguide systems 1602 to send test to test a configuration
Petition 870190094101, of 9/19/2019, p. 107/263
101/206 routing that was used before the detected disturbance (or disturbances). Test signals can be sent to the affected 1602 waveguide systems close to the disturbance. Test signals can be used to determine whether signal disturbances (for example, electromagnetic wave reflections) are detected by any of the 1602 waveguide systems. If the test signals confirm that a previous routing configuration is no longer is subject to the previously detected disturbance (or disturbances), then the network management system 1601 can, in step 1772, direct the affected waveguide systems 1602 to restore a previous routing configuration. If, however, the test signals analyzed by one or more waveguide coupling devices 1402 and reported to the network management system 1601 indicate that the disturbance (or disturbances) or new disturbance (or disturbances) is present, then the network management system 1601 will proceed to step 1768 and report this information to field personnel to further address field problems. In this situation, the network management system 1601 can continue to monitor the mitigation of the disturbance (or disturbances) in step 1762.
[0200] In the modalities mentioned above, the 1602 waveguide systems can be configured to adapt to changes in the 1653 electrical network and / or to mitigate disturbances. That is, one or more affected 1602 waveguide systems can be configured to self-monitor disturbance mitigation and reconfigure
Petition 870190094101, of 9/19/2019, p. 108/263
102/206 traffic routes without requiring instructions to be sent to them by the network management system 1601. In this mode, one or more waveguide systems 1602 that are self-configuring can inform the network management system 1601 of their routing choices, so that the network management system 1601 can maintain a macro level view of the communication topology of the 1655 communication system.
[0201] Although, for the sake of simplicity of explanation, the respective processes are shown and described as a series of blocks in Figures 17A and 17B, respectively, it must be understood and recognized that the claimed matter under discussion is not limited by the order of the blocks , since some blocks can occur in different orders and / or simultaneously with other blocks in relation to what is represented and described here. In addition, not all illustrated blocks may be required to implement the methods described here.
[0202] Moving now to Figure 18A, a block diagram is shown illustrating a non-limiting example of a 1800 transmission medium for the propagation of guided electromagnetic waves. In particular, another example of transmission means 125 shown in conjunction with Figure 1 is shown. In one embodiment, transmission means 1800 may comprise a first dielectric material 1802 and a second dielectric material 1804 arranged therein. In one embodiment, the first dielectric material 1802 may comprise a dielectric core (hereinafter referred to as dielectric core 1802) and the second material
Petition 870190094101, of 9/19/2019, p. 109/263
Dielectric 103/206 1804 may comprise a coating or a cover, such as, for example, a dielectric foam that surrounds all or part of the dielectric core (referred to herein as 1804 dielectric foam). In one embodiment, the dielectric core 1802 and the dielectric foam 1804 can be coaxially aligned with each other (although it is not necessary). In one embodiment, the combination of the dielectric core 1802 and the dielectric foam 1804 can be bent or curved at least 45 degrees without damaging the materials of the dielectric core 1802 and the dielectric foam 1804. In one embodiment, an outer surface of the 1804 dielectric foam can be further surrounded in whole or in part by a third dielectric material 1806, which can serve as an outer shell (hereinafter referred to as shell 1806). The casing 1806 can prevent exposure of the dielectric core 1802 and dielectric foam 1804 to an environment that could adversely affect the spread of electromagnetic waves (eg, water, soil, etc.).
[0203] The dielectric core 1802 may comprise, for example, a high density polyethylene material, a high density polyurethane material or other suitable dielectric material (s). The 1804 dielectric foam may comprise, for example, a cellular plastic material, such as, for example, an expanded polyethylene material or other suitable dielectric material (s). The casing 1806 may comprise, for example, a polyethylene material or equivalent. In one embodiment, the dielectric constant of the 1804 dielectric foam may be (or substantially) less than the dielectric constant of the
Petition 870190094101, of 9/19/2019, p. 110/263
104/206 dielectric core 1802. For example, the dielectric constant of dielectric core 1802 can be approximately 2.3, while the dielectric constant of dielectric foam 1804 can be approximately 1.15 (slightly higher than the air dielectric constant).
[0204] The 1802 dielectric core can be used to receive signals in the form of electromagnetic waves from a launcher or other coupling device described here that can be configured to launch guided electromagnetic waves into the 1800 transmission medium. In one embodiment, the Transmission 1800 can be coupled to a structured hollow waveguide 1808 such as, for example, a circular waveguide 1809, which can receive electromagnetic waves from a radiation device such as a stub antenna (not shown). The hollow waveguide 1808 can, in turn, induce guided electromagnetic waves in the 1802 dielectric core. In this configuration, the guided electromagnetic waves are guided by, or connected to, the 1802 dielectric core and propagate longitudinally along the 1802 dielectric core. By adjusting the launcher's electronics, it is possible to choose an operating frequency for the electromagnetic waves, so that an 1810 field strength profile of the guided electromagnetic waves extends nominally (or not at all) outside the 1806 enclosure.
[0205] Maintaining most (if not all) of the field strength of guided electromagnetic waves within portions of the dielectric core 1802, the dielectric foam 1804 and / or the casing 1806, the 1800 transmission medium can be used in hostile environments without adversely affecting the spread of
Petition 870190094101, of 9/19/2019, p. 111/263
105/206 electromagnetic waves there. For example, the transmission medium 1800 can be buried in the ground with no (or almost no) adverse effect for the guided electromagnetic waves propagating in the transmission medium 1800. Similarly, the transmission medium 1800 can be exposed to water (for example , rain or placed under water) with no (or almost no) adverse effects for the guided electromagnetic waves propagating in the 1800 transmission medium. In one embodiment, the loss of propagation of guided electromagnetic waves in the previous modes can correspond to the 2 dB per meter or better at an operating frequency of 60 GHz. Depending on the operating frequency of the guided electromagnetic waves and / or the materials used for the 1800 transmission medium, further propagation losses may be possible. Additionally, depending on the materials used to build the 1800 transmission medium, the 1800 transmission medium may in some ways bend on the side with no (or almost no) adverse effect on the guided electromagnetic waves propagating through the 1802 dielectric core and the foam dielectric 1804.
[0206] Figure 18B represents a transmission medium 1820 that differs from the transmission medium 1800 of Figure 18A, and still provides another example of the transmission medium 125 presented together with Figure 1. The transmission medium 1820 shows numbers of similar references for similar elements of the transmission means 1800 of Figure 18A. In opposition to the transmission medium 1800, the transmission medium 1820 comprises a conductive core 1822 having an insulating layer 1823 surrounding the conductive core 1822 in the

106/206 in whole or in part. The combination of insulation layer 1823 and conductor core 1822 will be referred to here as an isolated conductor 1825. In the illustration in Figure 18B, insulation layer 1823 is protected in whole or in part by a dielectric foam 1804 and housing 1806, which can be be constructed from the materials previously described. In one embodiment, the insulation layer 1823 can comprise a dielectric material, such as, for example, polyethylene, having a higher dielectric constant than the 1804 dielectric foam (for example, 2.3 and 1.15, respectively). In one embodiment, the components of the 1820 transmission medium can be coaxially aligned (although not required). In one embodiment, a hollow waveguide 1808 that has metal plates 1809, which can be separated from the insulation layer 1823 (although not necessary) can be used to launch guided electromagnetic waves that propagate substantially on an outer surface of the insulation 1823, however, other coupling devices as described in this document can also be employed. In one embodiment, the guided electromagnetic waves can be sufficiently guided or linked by the insulation layer 1823 to guide the electromagnetic waves longitudinally along the insulation layer 1823. By setting the launcher's operating parameters, an operating frequency of the guided electromagnetic waves launched by the guide hollow wave 1808 can generate an 1824 electric field strength profile that results in substantial confinement of guided electromagnetic waves within the 1804 dielectric foam

107/206 thus preventing the guided electromagnetic waves from being exposed to an environment (for example, water, soil, etc.) that adversely affects the propagation of the guided electromagnetic waves via the 1820 transmission medium.
[0207] Figure 18C represents a transmission medium 1830 which differs from the transmission means 1800 and 1820 of Figures 18A and 18B, but provides another example of the transmission medium 125 presented together with Figure 1. The transmission medium 1830 shows similar reference numbers for similar elements of the transmission means 1800 and 1820 of Figures 18A and 18B, respectively. In contrast to the transmission means 1800 and 1820, the transmission means 1830 comprises a bare (or non-insulated) conductor 1832 surrounded in whole or in part by the dielectric foam 1804 and the casing 1806, which can be constructed from the materials previously described . In one embodiment, the components of the 1830 transmission medium can be coaxially aligned (although not required). In one embodiment, a hollow waveguide 1808 that has metal plates 1809 attached to the bare conductor 1832 can be used to launch guided electromagnetic waves that propagate substantially on an external surface of the bare conductor 1832, however, other coupling devices described in this document can also be used. In one embodiment, the guided electromagnetic waves can be sufficiently guided or linked by the 1832 bare conductor to guide the longitudinally guided electromagnetic waves along the 1832 bare conductor.

108/206 of the launcher, an operating frequency of the guided electromagnetic waves launched by the hollow waveguide 1808 can generate an 1834 electric field strength profile that results in substantial confinement of the guided electromagnetic waves within the 1804 dielectric foam thus preventing electromagnetic waves guided tours are exposed to an environment (for example, water, soil, etc.) that adversely affects the propagation of electromagnetic waves via the 1830 transmission medium.
[0208] It should be noted that the hollow launcher 1808 used with the transmission means 1800, 1820 and 1830 of Figures 18A, 18B and 18C, respectively, can be replaced by other launchers or coupling devices. In addition, the mode (s) of propagation of electromagnetic waves for any of the above modalities may be fundamental mode (s), non-fundamental mode (s) (or asymmetric) ) or combinations thereof.
[0209] Figure 18D is a block diagram illustrating an example non-limiting embodiment of transmission means grouped 1836 according to various aspects described herein. The grouped transmission means 1836 may comprise a plurality of cables 1838 held in place by a flexible sleeve 1839. The plurality of cables 1838 may comprise multiple instances of cable 1800 in Figure 18A, multiple instances of cable 1820 in Figure 18B, multiple instances of cable 1830 of Figure 18C, or any combination thereof. Sleeve 1839 may comprise a dielectric material that prevents soil, water or other external materials from being in contact with the plurality of
Petition 870190094101, of 9/19/2019, p. 115/263
109/206 cables 1838. In one embodiment, a plurality of launchers, each using a transceiver similar to that shown in Figure 10A or other coupling devices described here, can be adapted to selectively induce an electromagnetic wave guided on each cable, each wave guided electromagnetic conducting different data (for example, voice, video, messages, content, etc.). In one embodiment, by adjusting operational parameters of each launcher or other coupling device, the electric field strength profile of each guided electromagnetic wave can be totally or substantially confined within layers of a corresponding 1838 cable to reduce crosstalk between 1838 cables.
[0210] In situations where the electric field intensity profile of each guided electromagnetic wave is not totally or substantially confined within a corresponding 1838 cable, the crosstalk of electromagnetic signals can occur between 1838 cables as illustrated by the signal plots associated with the two cables shown in Figure 18E. The plots in Figure 18E show that when a guided electromagnetic wave is induced in a first cable, the electrical and magnetic fields emitted from the first cable can induce signals in the second cable, which results in crosstalk. Several mitigation options can be used to reduce crosstalk between the 1838 cables in Figure 18D. In one embodiment, an 1840 absorption material that can absorb electromagnetic fields, such as carbon, can be applied to 1838 cables as shown in Figure 18F to polarize each guided electromagnetic wave in various states of
Petition 870190094101, of 9/19/2019, p. 116/263
110/206 polarization to reduce crosstalk between 1838 cables. In another embodiment (not shown), carbon microspheres can be added to the gaps between 1838 cables to reduce crosstalk.
[0211] In yet another embodiment (not shown), an 1838 cable diameter can be configured differently to vary a propagation speed of guided electromagnetic waves between 1838 cables in order to reduce crosstalk between 1838 cables. modality (not shown), a shape of each 1838 cable can be made asymmetrical (for example, elliptical) to direct the guided electromagnetic fields of each 1838 cable away from each other in order to reduce crosstalk. In one embodiment (not shown), a filler material such as dielectric foam can be added between 1838 cables to sufficiently separate the 1838 cables to reduce crosstalk between them. In one embodiment (not shown), longitudinal carbon strips or swirls can be applied to an outer surface of the 1806 jacket of each 1838 cable to reduce radiation from guided electromagnetic waves outside of the 1806 jacket and thereby reduce the crosstalk between 1838 cables. In yet another modality, each launcher can be configured to launch a guided electromagnetic wave having a different frequency, modulation and wave propagation mode, such as, for example, a frequency, a modulation or an orthogonal mode, for reduce crosstalk between 1838 cables.
[0212] In yet another mode (not shown), the 1838 cable pairs can be twisted into a helix to
Petition 870190094101, of 9/19/2019, p. 117/263
111/206 reduce crosstalk between pairs and other 1838 cables in a vicinity of pairs. In some embodiments, certain 1838 cables can be stranded, while other 1838 cables are not stranded to reduce crosstalk between 1838 cables. In addition, each 1838 twisted pair cable can have different slopes (ie, different torsion rates, such as, for example, twists per meter) to further reduce crosstalk between pairs and other 1838 cables near the pairs. In another embodiment (not shown), launchers or other coupling devices can be configured to induce guided electromagnetic waves in 1838 cables having electromagnetic fields that extend beyond the 1806 enclosure to the gaps between the cables to reduce crosstalk between the cables 1838. It is submitted that any of the previous modalities for the mitigation of crosstalk between 1838 cables can be combined to further reduce crosstalk between them.
[0213] Figures 18G and 18H are block diagrams illustrating non-limiting examples of a transmission medium with an internal waveguide according to various aspects described here. In one embodiment, a transmission medium 1841 may comprise a core 1842. In one embodiment, the core 1842 may be a dielectric core 1842 (for example, polyethylene. In another embodiment, the core 1842 may be an isolated or non-isolated conductor Core 1842 can be surrounded by a cap 1844 that comprises a dielectric foam (for example, expanded polyethylene material) that has a dielectric constant less than the dielectric constant of a dielectric core, or layer of
Petition 870190094101, of 9/19/2019, p. 118/263
112/206 insulation of a conductive core. The difference in dielectric constants makes it possible for the electromagnetic waves to be connected and guided by the 1842 core. The 1844 cover can be covered by an 1845 cover shell. The 1845 cover shell can be produced from rigid material (for example, high density) or a material with high tensile strength (for example, synthetic fiber). In one embodiment, the cover 1845 can be used to prevent exposure of the cover 1844 and core 1842 from an adverse environment (for example, water, moisture, dirt, etc.). In one embodiment, the cover shell 1845 can be sufficiently rigid to separate an outer surface of the core 1842 from an internal surface of the cover shell 1845, thereby resulting in a longitudinal gap between the cover shell 1854 and the core 1842. The longitudinal gap can be filled with the dielectric foam of the cover 1844.
[0214] The transmission means 1841 may additionally include a plurality of outer ring conductors 1846. The outer ring conductors 1846 may be filaments of conductive material that has been woven around the cover wrap 1845, thereby covering the wrapping wrapper. cover 1845 in whole or in part. The 1846 outer ring conductors can serve as a power line that has an electrical return path similar to the modalities described in the disclosure of matter to receive power signals from a source (for example, a transformer, a power generator, etc.). In one embodiment, the outer ring conductors 1846 may be covered by an 1847 cable jacket to prevent exposure of the outer ring conductors 184 6 to water,
Petition 870190094101, of 9/19/2019, p. 119/263
113/206 dirt or other environmental factors. The 1847 cable jacket can be produced from an insulating material such as polyethylene. The 1842 core can be used as a central waveguide for the propagation of electromagnetic waves. A hollow waveguide launcher 1808, like the circular waveguide discussed earlier, can be used to launch signals that induce electromagnetic waves guided by the 1842 core in ways similar to those described for the embodiments of Figures 18A, 18B and 18C. Electromagnetic waves can be guided by the 1842 core without using the electrical return path of the 1846 outer ring conductors or any other electrical return path. By adjusting the electronics of the 1808 launcher, an operating frequency of the electromagnetic waves can be chosen so that a field strength profile of the guided electromagnetic waves extends nominally (or does not extend at all) outside the 1845 cover. [0215] In another embodiment, a transmission means 1843 may comprise a hollow core 1842 'surrounded by a cover shell 1845'. The cover shell 1845 'may have an inner conductive surface or other surface materials that allow the hollow core 1842' to be used as a conduit for electromagnetic waves. The cover shell 1845 'can be protected at least in part with the outer ring conductors 1846 described above for conducting a power signal. In one embodiment, an 1847 cable jacket can be arranged on an outer surface of the outer ring conductors 1846 to prevent exposure of the outer ring conductors 1846 to water, dirt
Petition 870190094101, of 9/19/2019, p. 120/263
114/206 or other environmental factors. A 1808 waveguide launcher can be used to launch electromagnetic waves guided by the hollow core 1842 'and the conductive interior surface of the cover shell 1845'. In one embodiment (not shown), the hollow core 1842 'may further include a dielectric foam as described above.
[0216] The 1841 transmission medium may represent a multi-purpose cable that conducts power to the 1846 outer ring conductors using an electrical return path and that provides communication services via an internal waveguide comprising a core combination 1842, of the cover 1844 and the cover of the cover 1845. The internal waveguide can be used to transmit or receive electromagnetic waves (without using an electrical return path) guided by the 1842 core. Similarly, the 1843 transmission medium can represent a multipurpose cable that conducts power to the outer ring conductors 1846 using an electrical return path and that provides communication services by means of an inner waveguide comprising a combination of the hollow core 1842 'and the shell 1845'. The inner waveguide can be used for the transmission or reception of electromagnetic waves (without the use of an electrical return path) guided by the hollow core 1842 'and the cover shell 1845'.
[0217] It is assumed that the modalities of Figures 18G to 18H can be adapted to use multiple internal waveguides surrounded by the outer ring conductors 1846. The internal waveguides can be adapted to use for
Petition 870190094101, of 9/19/2019, p. 121/263
115/206 crosstalk mitigation techniques described above (for example, twisted pairs of waveguides, waveguides of different structural dimensions, use of polarizers inside the cover, use of different wave modes, etc.).
[0218] For purposes of illustration only, the transmission means 1800, 1820, 1830, 1836, 1841 and 1843 will be referred to herein as an 1850 cable with an understanding that the 1850 cable can represent any of the described transmission means in the dissemination of the matter, or a grouping of multiple instances of them. For purposes of illustration only, the dielectric core 1802, the isolated conductor 1825, the bare conductor 1832, the core 1842 or the hollow core 1842 'of the transmission means 1800, 1820, 1830, 1836, 1841 and 1843, respectively, will be here referred to as transmission core 1852 with an understanding that cable 1850 can use dielectric core 1802, insulated conductor 1825, bare conductor 1832, core 1842 or hollow core 1842 'of transmission means 1800, 1820, 1830, 1836, 1841 and / or 1843, respectively.
[0219] Turning now to Figures 181 and 18J, block diagrams illustrating example non-limiting modalities of connector configurations that can be used by 1850 cable are shown. In one embodiment, the 1850 cable can be configured with a female connection arrangement or a male connection arrangement as shown in Figure 181. The male configuration, on the right of Figure 181, can be obtained by extracting the 1804 dielectric foam ( and casing 1806, if any) to expose a portion of the 1852 transmission core. The female configuration, on the left
Petition 870190094101, of 9/19/2019, p. 122/263
116/206 of Figure 181, can be obtained by removing a portion of the transmission core 1852, while maintaining the dielectric foam 1804 (and casing 1806, if any). In an embodiment in which the transmission core 1852 is hollow, as described in relation to Figure 18H, the male portion of the transmission core 1852 can represent a hollow core with a rigid outer surface that can slide into the female arrangement on the left side of Figure 181 to align the hollow cores together. It is also noted that in the modalities of Figures 18G to 18H, the outer ring of conductors 1846 can be modified to connect male and female portions of the 1850 cable.
[0220] Based on the aforementioned modalities, the two 1850 cables that have male and female connector arrangements can be combined together. A sleeve with an adhesive inner liner or retractable packaging material (not shown) can be applied to an area of a joint between 1850 cables to keep the joint in a fixed position and prevent its exposure (for example, to water, dirt, etc.) . When the 1850 cables are combined, the 1852 transmission core of one cable will be in close proximity to the 1852 transmission core of the other cable. Guided electromagnetic waves that propagate through any of the 1852 transmission cores of 1850 cables that run in any direction can cross between the 1852 transmission cores disjunctions in the possibility that the 1852 transmission cores touch, whether or not of the 1852 transmission cores
Petition 870190094101, of 9/19/2019, p. 123/263
117/206 are coaxially aligned and / or whether or not there is a gap between the 1852 transmission cores.
[0221] In another embodiment, a junction device 18 60 that has female connector arrangements at both ends can be used to mate 1850 cables that have male connector arrangements as shown in Figure 18J. In an alternative embodiment not shown in Figure 18J, the joining device 1860 can be adapted to have male connector arrangements at both ends that can be attached to 1850 cables that have female connector arrangements. In another embodiment not shown in Figure 18J, the 1860 junction device can be adapted to have a male connector arrangement and a female connector arrangement at opposite ends that can be attached to the 1850 cables that have a female and male connector arrangement, respectively. It is further noted that a transmission core 1852 having a hollow core, the female and male arrangements described in Figure 181 can be applied to the junction device 1860 in the possibility that the ends of the junction device 1860 are either male, female or a combination the same.
[0222] The previously mentioned modalities for connecting the cables illustrated in Figures 181 to 18J can be applied to each single instance of cable 1838 of grouped transmission media 1836. Similarly, the modalities previously illustrated in Figures 181 to 18J can be applied to each single instance of an internal waveguide for an 1841 or 1843 cable that has multiple internal waveguides.
Petition 870190094101, of 9/19/2019, p. 124/263
118/206 [0223] Moving now to Figure 18K, a block diagram is shown illustrating non-limiting modalities of example of 1800 ', 1800' ', 1800' '' and 1800 '' 'transmission means for the propagation of guided electromagnetic waves. In one embodiment, a transmission means 1800 'can include a core 1801 and a dielectric foam 1804' divided into sections and protected by a casing 1806 as shown in Figure 18K. Core 1801 can be represented by the dielectric core 1802 of Figure 18A, the isolated conductor 1825 of Figure 18B or the bare conductor 1832 of Figure 18C. Each section of 1804 'dielectric foam can be separated by an interval (for example, air, gas, vacuum, or a substance with a low dielectric constant). In one embodiment, the gap separations between the 1804 'dielectric foam sections can be almost random as shown in Figure 18K, which can be useful in reducing electromagnetic wave reflections occurring in each 1804' dielectric foam section as they propagate. longitudinally along the core 1801. The sections of the dielectric foam 1804 'can be constructed, for example, as washers made of a dielectric foam having an interior opening to support the core 1801 in a fixed position. For purposes of illustration only, washers will be referred to herein as 1804 'washers. In one embodiment, the inner opening of each washer 1804 'can be coaxially aligned with an axis of the core 1801. In another embodiment, the inner opening of each washer 1804' can be displaced relative to the axis of the core 1801. In another embodiment ( not shown), each washer 1804 'can have a thickness
Petition 870190094101, of 9/19/2019, p. 125/263
119/206 variable longitudinal as shown by the differences in the thickness of the washers 1804 '.
[0224] In an alternative embodiment, a 1800 '' transmission medium may include a 1801 core and a 1804 '' dielectric foam tape wrapped around the core in a propeller protected by a 1806 housing as shown in Figure 18K. Although it may not be evident from the drawing shown in Figure 18K, in one embodiment, the 1804 '' dielectric foam tape can be braided around the 1801 core with varying slopes (ie, different torsion rates) for different sections of the 1804 '' dielectric foam tape. The use of variable slopes can help to reduce reflections or other disturbances of electromagnetic waves occurring between areas of the 1801 core not protected by 1804 '' dielectric foam tape. It is further noted that the thickness (the diameter) of the 1804 '' dielectric foam tape can be substantially greater (e.g., 2 or more times greater) than the core diameter 1801 shown in Figure 18K.
[0225] In an alternative embodiment, a 1800 '' 'transmission medium (shown in a cross-sectional view) may include a 1801' non-circular core protected by a 1804 dielectric foam and a 1806 housing. In one embodiment, the core 1801 'non-circular structure may have an elliptical structure as shown in Figure 18K, or another suitable non-circular structure. In another embodiment, the non-circular core 1801 'may have an asymmetric structure. A 1801 'non-circular core can be used to polarize the electromagnetic wave fields induced in the non-circular core
Petition 870190094101, of 9/19/2019, p. 126/263
120/206 circular 1801 '. The 1801 'non-circular core structure can help preserve the polarization of electromagnetic waves as they propagate along the 1801' non-circular core.
[0226] In an alternative embodiment, a 1800 '' '' transmission medium (shown in a cross-sectional view) can include multiple 1801 '' cores (only two cores are shown, but more are possible). The multiple 1801 '' cores can be protected by a 1804 dielectric foam and a 1806 casing. The multiple 1801 '' cores can be used to polarize the electromagnetic wave fields induced in the multiple 1801 '' cores. The structure of the multiple cores 1801 'can preserve the polarization of the guided electromagnetic waves while they propagate along the multiple cores 1801' '.
[0227] It will be noted that the modalities of Figure 18K can be used to modify the modalities of Figures 18G to 18H. For example, core 1842 or core 1842 'can be adapted to use sectioned covers 1804' with gaps between them, or one or more 1804 '' dielectric foam strips. Similarly, core 1842 or core 1842 'can be adapted to have a non-circular core 1801' which can have a symmetrical or asymmetric cross-sectional structure. In addition, the 1842 core or the 1842 'core can be adapted to use multiple 1801' 'cores in a single inner waveguide, or different numbers of cores when multiple inner waveguides are used. Thus, any of the modalities shown in Figure 18K
Petition 870190094101, of 9/19/2019, p. 127/263
121/206 can be applied alone or in combination with the 18G to 18H modes.
[0228] Turning now to Figure 18L, we have a block diagram illustrating non-limiting modalities of example of grouped transmission means to mitigate crosstalk according to several aspects described here. In one embodiment, a grouped transmission medium 1836 'may include 1803 variable core structures. By varying the structures of the 1803 cores, the induced electromagnetic wave fields induced in each of the cores of the 1836 'transmission medium may differ sufficiently to reduce the crosstalk between 1838 cables. In another embodiment, the 1836' 'grouped transmission means may include a varying number of cores 1803 'per 1838 cable. By varying the number of cores 1803' per 1838 cable, the guided electromagnetic wave fields induced in one or more cores of the 1836 '' transmission medium can differ sufficiently to reduce the crosstalk between cables 1838. In another embodiment, cores 1803 or 1803 'may be of different materials. For example, cores 1803 or 1803 'can be a dielectric core 1802, an insulated conductor core 1825, a bare conductor core 1832 or any combination thereof.
[0229] Note that the modalities illustrated in Figures 18A to 18D and 18F to 18H can be modified and / or combined with some of the modalities in Figures 18K to 18L. Note, additionally, that one or more of the modalities illustrated in Figures 18K and 18L can be combined (for example, using sectioned dielectric foam 1804 'or a
Petition 870190094101, of 9/19/2019, p. 128/263
122/206 1804 '' dielectric foam propeller with 1801 ', 1801', 1803 or 1803 'cores). In some embodiments, guided electromagnetic waves propagating in the 1800 ', 1800' ', 1800' '' and / or 1800 '' '' transmission media of Figure 18K may experience less propagation losses than guided electromagnetic waves propagating in transmission means 1800, 1820 and 1830 of Figures 18A to 18C. In addition, the modalities illustrated in Figures 18K to 18L can be adapted to use the connectivity modalities illustrated in Figures 181 to 18J.
[0230] Moving now to Figure 18M, a block diagram is shown illustrating a non-limiting example of tapered stubs exposed from the 1836 grouped transmission media for use as 1855 antennas. Each 1855 antenna can serve as a directional antenna for radiation of wireless signals directed to wireless communication devices or to induce the propagation of electromagnetic waves on a surface of a transmission medium (for example, a power line). In one embodiment, the wireless signals radiated by the 1855 antennas can be beam-oriented adapting the phase and / or other characteristics of the wireless signals generated by each 1855 antenna. In one embodiment, the 1855 antennas can be individually placed in a set of dish antennas to direct wireless signals in multiple directions.
[0231] It is further noted that the terms core, coating, cover and foam as used in the disclosure under discussion can comprise any types of materials (or combinations of materials) that allow the
Petition 870190094101, of 9/19/2019, p. 129/263
123/206 electromagnetic waves remain connected to the nucleus while propagating longitudinally along the nucleus. For example, a 1804 '' dielectric foam tape described above can be replaced with a tape of a common dielectric material (e.g., polyethylene) to wrap around the 1802 dielectric core (referred to here for illustrative purposes only as a wrap). In this configuration, an average wrap density can be small as a result of the air gap between sections of the wrap. Consequently, an effective envelope dielectric constant can be less than the dielectric constant of the 1802 dielectric core, thus allowing the guided electromagnetic waves to remain connected to the core. Consequently, any of the modalities of the disclosure under discussion related to materials used for core (or cores) and wraps around the core (or cores) can be structurally adapted and / or modified with other dielectric materials that achieve the result of keeping the waves electromagnetic elements connected to the nucleus (or nuclei) while propagating along the nucleus (or nuclei). In addition, a core in whole or in part as described in any of the disclosure modalities under discussion may comprise an opaque material (for example, polyethylene). Consequently, guided electromagnetic waves connected to the core will have a non-optical frequency range (for example, less than the lowest visible light frequency).
[0232] Figures 18N, 180, 18P, 18Q, 18R, 18S and 18T are block diagrams illustrating non-limiting modalities

124/206 example of a waveguide device for the transmission or reception of electromagnetic waves in accordance with various aspects described herein. In one embodiment, Figure 18N illustrates a front view of a 1865 waveguide system having a plurality of grooves 1863 (for example, openings or holes) for the emission of electromagnetic waves having irradiated electric fields (fields) 1861. In one mode, the radiated e-fields 1861 of pairs of symmetrically positioned grooves 1863 (for example, north and south grooves of the 1865 waveguide system) can be directed away from each other (ie polar opposite radial orientations around the cable 1862). Although the 1863 grooves are shown to have a rectangular shape, other shapes like other polygons, sectors and arc shapes, elliptical shapes and other shapes are also possible. For purposes of illustration only, the term north will refer to a relative direction as shown in the Figures. All references in the dissemination of the material to other directions (for example, south, east, west, northwest, and so on) will be in relation to the northeast illustration. In one embodiment, to obtain e-fields with opposite orientations in the north and south slots 1863, for example, the north and south slots 1863 can be arranged to have a circumferential distance from each other which is approximately a wavelength of electromagnetic wave signals. provided to these slots. The 18 65 waveguide system can have a cylindrical cavity in a center of the 1865 waveguide system to allow the placement of an 1862 cable. In one embodiment, the 1862 cable
Petition 870190094101, of 9/19/2019, p. 131/263
125/206 can comprise an isolated conductor. In another embodiment, cable 18 62 may comprise an uninsulated conductor. In yet another embodiment, cable 18 62 can comprise any of the embodiments of a transmission core 1852 of cable 1850 described above.
[0233] In one embodiment, the 1862 cable can slide into the cylindrical cavity of the 1865 waveguide system. In another embodiment, the 1865 waveguide system can use a mounting mechanism (not shown). The mounting mechanism (for example, a hinge or other suitable mechanism that provides a way to open the 1865 waveguide system in one or more locations) can be used to allow the placement of the 1865 waveguide system on a surface outer cable 1862 or to assemble separate parts together to form the waveguide system 18 65 as shown. According to these and other
modalities appropriate, the system in guide in wave 1865 can be configured to curl in lathe of cable 1862 like a necklace.[0234] A Figure 180 illustrates one and 1 view side of an
modality of the waveguide system 18 65. The waveguide system 1865 can be adapted to have a hollow rectangular waveguide portion 18 67 that receives electromagnetic waves 1866 generated by a transmitting circuit as previously described in the disclosure under discussion ( for example, see reference 101, 1000 of Figures 1 and 10A). The 1866 electromagnetic waves can be distributed over the hollow rectangular 1867 waveguide portion within a hollow collar 1869 of the 1865 waveguide system.
Petition 870190094101, of 9/19/2019, p. 132/263
126/206 rectangular waveguide 1867 and hollow collar 1869 can be constructed of materials suitable for maintaining the electromagnetic waves within the hollow chambers of these assemblies (for example, carbon fiber materials). It should be noted that although the waveguide portion 18 67 is shown and described in a hollow rectangular configuration, other shapes and / or other non-hollow configurations can be employed. In particular, the waveguide portion 1867 may have a square or other polygon cross section, an arc or sector cross section that is truncated to conform to the outer surface of the 1862 cable, a circular or elliptical section or shaped cross section. In addition, the waveguide portion 18 67 can be configured as, or otherwise includes, a solid dielectric material.
[0235] As previously described, the hollow collar 1869 can be configured to emit electromagnetic waves from each slot 1863 with e-fields 1861 opposite in pairs of grooves 1863 and 1863 'symmetrically positioned. In one embodiment, the electromagnetic waves emitted by the combination of grooves 18 63 and 18 63 'can, in turn, induce electromagnetic waves 1868 that are connected to the cable 1862 for propagation according to a fundamental wave mode without other modes of present waveforms, such as non-fundamental wave modes. In this configuration, the 1868 electromagnetic waves can propagate longitudinally along the 1862 cable to other downstream waveguide systems coupled to the 1862 cable.
Petition 870190094101, of 9/19/2019, p. 133/263
127/206 [0236] It should be noted that, since the hollow rectangular 1867 waveguide portion of Figure 180 is closest to slot 1863 (in the position north of the 1865 waveguide system), slot 1863 it can emit electromagnetic waves having a stronger magnitude than the electromagnetic waves emitted by groove 1863 '(in the south position). To reduce magnitude differences between these grooves, the groove 1863 'can be made larger than the groove 1863. The technique of using different groove sizes to balance signal magnitudes between grooves can be applied to any of the modalities of disclosure of the related matter Figures 18N, 180, 18Q, 18S, 18U and 18V - some of which are described below.
[0237] In another embodiment, Figure 18P represents an 18 65 'waveguide system that can be configured to use the set of circuits, such as microwave monolithic integrated circuits (MMIC) 1870, each coupled in a 1872 signal input (for example, a coaxial cable or other signal inputs that provide a communication signal). The 1872 signal input can be generated by a transmitter circuit as previously described in the disclosure (for example, see references 101, 1000 of Figures 1 and 10A) adapted to provide electrical signals for the MMIC 1870. Each MMIC 1870 can be configured to receive an 1872 signal that the MMIC 1870 can modulate and transmit with a radiation element (for example, an antenna or other devices) to emit electromagnetic waves having radiated e-fields 1861. In one embodiment, the MMIC 1870 can be configured to receive
Petition 870190094101, of 9/19/2019, p. 134/263
128/206 the same 1872 signal, but transmit electromagnetic waves having 1861 e-fields of different orientations. This can be accomplished by configuring one of the MMIC 1870 to transmit electromagnetic waves that are in a controllable phase from the electromagnetic waves transmitted by the other MMIC 1870. In the example shown, e-fields 1861 are generated with opposite phases (180 degrees out of phase ), however, other configurations, including transmission of signals in phase with each other, are possible, depending on the selected guided wave mode to be generated. In one embodiment, the combination of the electromagnetic waves emitted by the MMIC 1870 can jointly induce electromagnetic waves 1868 that are connected to the cable 1862 for propagation according to a particular wave mode with no other wave modes present. In this configuration, the 1868 electromagnetic waves can propagate longitudinally along the 1862 cable to other downstream waveguide systems coupled to the 1862 cable.
[0238] In several modalities, a reflective plate 1871 is also included in a region behind the radiation elements of the MMIC 1870 in relation to the direction of propagation of the electromagnetic waves 18 68 which are guided by the cable 1862, indicated by the wave direction arrow that is shown. The reflective plate can be constructed from a metallic plate, a metallic coated surface, a phantom mesh that has sufficient density to reflect electromagnetic waves moving towards the 1871 reflective plate from the MMIC 1870, or another reflective plate.
[0239] In operation, the 1871 reflective plate assists in directing the instances of electromagnetic waves
Petition 870190094101, of 9/19/2019, p. 135/263
129/206
61 for an interface of a transmission medium, such as the surface of the cable 1862, to induce the propagation of electromagnetic waves 1868 along the cable 1862. For example, the reflective plate 1871 can be reduced to the ground and / or the external housing of the waveguide system 18 65 to interact with the 1861 e-fields generated by the MMIC.
[0240] In the mode shown, the reflective plate 1871 is positioned inside the outer housing of the 18 65 'waveguide system in a configuration that is perpendicular to the longitudinal geometric axis of the cable 18 62 and the wave direction, and optionally is parallel to a plane that contains the radiation elements of the MMIC 1870, however, other configurations are similarly possible. In several embodiments, the distance dl between the reflective plate and the radiation elements of the MMIC 1870 can be adjusted or otherwise defined to withstand the induction of the propagation of the 1868 electromagnetic waves through a selected non-fundamental or fundamental wave mode, such as TMoo, HEn, EHim, TMom, (where m = 1, 2,...) Or other non-fundamental and / or asymmetric modes at a chosen operating frequency. For example, the distance dl can be adjusted incrementally to determine the particular value of dl that yields the highest signal strength of one or more selected modes of the 1868 electromagnetic waves.
[0241] An 1880 tapered horn, such as a conductive horn, or other coaxial reflectors can be added to the modalities of the Figures. 180 and 18P to assist in directing 1861 e-fields to induce 1868 electromagnetic waves on cable 1862
Petition 870190094101, of 9/19/2019, p. 136/263
130/206 as shown in Figures 18Q and 18R. Although a particular configuration of an 1880 tapered horn is shown, other cone configurations including an enlarged cone, a pyramidal horn or other horn designs could be employed in a similar manner.
[0242] In one embodiment, when the 1862 cable is a non-insulated conductor, the electromagnetic waves induced in the 1862 cable can have a large radial dimension (for example, 1 meter). To enable the use of a smaller tapered horn 1880, an 1879 insulation layer can be applied to a portion of the cable 1862 in or near the cavity as shown with dashed lines in Figures 18Q and 18R. The insulation layer 1879 may have a tapered end facing away from the waveguide system 18 65. The added insulation allows the electromagnetic waves 1868 initially launched by the waveguide system 1865 (or 1865 ') to be firmly attached to the cable 1862, which in turn reduces the radial dimension of the 1868 electromagnetic fields (for example, centimeters). As the electromagnetic waves 1868 propagate away from the waveguide system 1865 (1865 ') and reach the tapered end of the insulation layer 1879, the radial dimension of the electromagnetic waves 1868 begins to increase, eventually reaching the radial dimension they would have if the 1868 electromagnetic waves had been induced in the non-isolated conductor without an insulation layer. In the illustration in Figures 18Q and 18R the tapered end begins at one end of the 1880 tapered horn. In other embodiments, the tapered end of the insulation layer
Petition 870190094101, of 9/19/2019, p. 137/263
131/206
1879 can start before or after the end of the tapered horn 1880. The tapered horn can be metallic or constructed of another conductive material or constructed of a plastic or other non-conductive material that is covered or coated with a dielectric layer or impregnated with a conductive material to provide reflective properties similar to a metal horn.
[0243] In several modalities, the distance d2 between the reflective plate and the radiation elements of the MMIC 1870 can be adjusted or otherwise defined to withstand the induction of the propagation of the electromagnetic waves 1868 through a non-fundamental or fundamental wave mode selected, such as TMoo, HEn, EHi _m , TMo _m , (where m = 1, 2, ...) or other non-fundamental and / or asymmetric modes at a chosen operating frequency. For example, the distance d2 can be adjusted incrementally to determine the particular value of d2 that yields the highest signal strength of one or more selected modes of the 1868 electromagnetic waves.
[0244] As previously noted, cable 1862 can comprise any of the modalities of cable 1850 described earlier. In this embodiment, the waveguides 1865 and 1865 'can be coupled to a transmission core 1852 of the cable 1850 as shown in Figures 18S and 18T. The waveguides 1865 and 1865 'can induce, as previously described, electromagnetic waves 1868 in the transmission core 1852 for the total or partial propagation within the inner layers of the cable 1850.
Petition 870190094101, of 9/19/2019, p. 138/263
132/206 [0245] Note that for the previous modalities of Figures 18Q, 18R, 18S and 18T, the electromagnetic waves 1868 can be bidirectional. For example, electromagnetic waves 1868 of a different operating frequency can be received by grooves 1863 or MMIC 1870 of waveguides 1865 and 1865 ', respectively. Once received, the electromagnetic waves can be converted by a receiver circuit (for example, see references 101, 1000 of Figures 1 and 10A) to generate a communication signal for processing.
[0246] In several modalities, the distance d3 between the reflective plate and the radiation elements of the MMIC 1870 can be adjusted or otherwise defined to withstand the induction of the propagation of the electromagnetic waves 1868 through a non-fundamental or fundamental wave mode selected, such as TMoo, HEu, EHi _m , TMo _m , (where m = 1, 2, ...) or other non-fundamental and / or asymmetric modes at a chosen operating frequency. For example, the distance d3 can be adjusted incrementally to determine the particular value of d3 that yields the highest signal strength of one or more selected modes of the 1868 electromagnetic waves.
[0247] Although not shown, it is further noted that waveguides 1865 and 1865 'can be adapted so that waveguides 1865 and 1865' can direct electromagnetic waves 1868 upstream or downstream longitudinally. For example, a first tapered horn 1880 coupled to a first instance of an 1865 or 1865 'waveguide system can be directed westward on cable 1862, while a second
Petition 870190094101, of 9/19/2019, p. 139/263
133/206 tapered horn 1880 coupled to a second instance of an 1865 or 1865 'waveguide system can be routed to it on cable 1862. The first and second instances of 1865 or 1865' waveguide can be coupled so that , in a repeater configuration, the signals received by the first waveguide system 1865 or 1865 'can be supplied to the second waveguide system 1865 or 1865' for retransmission in an eastward direction on the 1862 cable. repeater already described can also be applied from an east to west direction on cable 1862.
[0248] The 1865 'waveguide system of Figures 18P, 18R and 18T can also be constructed in other ways to generate electromagnetic fields that have asymmetric or non-fundamental wave modes. Figure 18U represents a modality of an 18 65 '' waveguide system that is adapted to generate electromagnetic fields that have one or more non-fundamental wave modes selected. The 1865 '' waveguide system includes functions and features similar to the 18 65 'waveguide system which are mentioned by common reference numbers. In place of MMIC 1870, an antenna 1873 operates to radiate the electromagnetic wave which is directed to an interface of the transmission medium 1862 or 1852 to propagate in the wave direction through one or more selected non-fundamental wave modes. In the example shown, antenna 1873 is a monopole antenna, however, other antenna configurations and radiation elements can be employed in a similar way.
Petition 870190094101, of 9/19/2019, p. 140/263
134/206 [0249] The reflective plate 1871 is also included in a region behind the antenna 1873 in relation to the direction of propagation of the electromagnetic waves 1868 which is guided by the cable 1862, indicated by the wave direction arrow that is shown. The 1871 reflective plate can be constructed of a metallic plate, a coated metal surface, a phantom mesh that has sufficient density to reflect electromagnetic waves that move towards the 1871 reflective plate from the 1873 antenna, or other reflective plates.
[0250] In operation, the 1871 reflective plate assists in directing the 1861 electromagnetic wave to an interface of a transmission medium, such as the surface of the 1862 cable, to induce the propagation of the 1868 electromagnetic waves along the 1862 cable - non-propagation requires an electrical return path. For example, the reflective plate 1871 can be earthed and / or coupled to the outer housing of the 1865 waveguide system in order to interact with the 1861 e-fields generated by the 1873 antenna.
[0251] In the modality shown, the reflective plate 1871 is positioned inside the outer housing of the 18 65 'waveguide system in a configuration that is perpendicular to the longitudinal geometric axis of the cable 18 62 and to the wave direction, and optionally is parallel to a plane containing the 1873 antenna, however, other configurations are similarly possible. In several embodiments, the d4 distance between the reflective plate and the 1873 antenna can be adjusted or otherwise defined to withstand the induction of the propagation of the 1868 electromagnetic waves through a selected non-fundamental or fundamental wave mode, such as TMoo, HEn,
Petition 870190094101, of 9/19/2019, p. 141/263
135/206
EHim, TMom, (where m = 1, 2,...) Or other non-fundamental and / or asymmetric modes at a chosen operating frequency. For example, the distance d4 can be adjusted incrementally to determine the particular value of d4 that yields the highest signal strength of one or more selected modes of the 1868 electromagnetic waves.
[0252] Although not expressly shown, a conductive horn, or other coaxial reflectors can be added to the modalities of Figure 18U to assist in directing the 1861 e-fields to induce 1868 electromagnetic waves in the 1862 cable.
[0253] The 1865 'waveguide system of Figures 18P, 18R and 18T can also be used together to generate electromagnetic fields that have asymmetric or non-fundamental wave modes. Figure 18V represents a modality of a waveguide system that includes two waveguide systems 1865'-1 and 1865'-2 that are adapted to generate electromagnetic fields that have one or more non-fundamental wave modes selected. The 1865'1 and 1865'-2 waveguide systems include functions and features similar to the 18 65 'waveguide system that are mentioned by common reference numbers.
[0254] Signal input 1872 can be generated by a transmitter circuit as previously described in the disclosure under discussion (for example, see reference 101, 1000 of Figures 1 and 10A) adapted to provide electrical signals for MMIC 1870 and 1870 ' . Each MMIC 1870 and 1870 'can be configured to receive the 1872 signal that the MMIC 1870 or 1870' can modulate and transmit with an
Petition 870190094101, of 9/19/2019, p. 142/263
136/206 radiation (for example, an antenna or other device) to emit electromagnetic waves that have radiated e-fields 1861 and 1861 '. In the configuration shown, each of the MMIC 1870 includes a radiation element that is arranged in a concentric and / or radial manner around the 1852 or 18 62 cable. The MMIC 1870 'also each includes a radiation element that is arranged in a concentric manner around the 1852 or 1862 cable, but in an angular displacement from the radiation elements of the MMIC 1870. In the orientation shown, the radiation elements of the MMIC 1870 are arranged at 90 and 270 degree angles, while the elements of radiation from MMIC 1870 'are arranged at angles of 0 and 180 degrees. It should be noted that the selection of angular displacements of the MMIC 1870 from each other and the angular displacements of MMIC 1870 together with the phase displacements of the 1872 signal input generated by each circuit can be used to support a fundamental mode of electromagnetic waves 1868 or a non-fundamental wave mode of 1868 electromagnetic waves with a desired spatial orientation.
[0255] In the modality shown, MMIC 1870 can be configured to receive the same 1872 signal, but transmit electromagnetic waves that have 1861 e-fields of opposite orientation. Similarly, MMIC 1870 'can be configured to receive the same 1872 signal, but transmit electromagnetic waves that have opposite orientation 1861' e-fields, with a 180 degree phase shift from 1861 e-fields. can be accomplished by configuring the MMIC 1870 and MMIC 1870 'to transmit electromagnetic waves with controllable phases. In one mode,
Petition 870190094101, of 9/19/2019, p. 143/263
137/206 the combination of the electromagnetic waves emitted by the MMIC 1870 can jointly induce electromagnetic waves 1868 which are connected to the cable 1862 for propagation according to a fundamental wave mode with no other wave modes present - as non-fundamental wave modes, however , depending on the phases chosen for the MMIC and the distance d5, other modes such as non-fundamental modes can also be selected. In this configuration, the 1868 electromagnetic waves can propagate longitudinally along the 1862 cable to other downstream waveguide systems coupled to the 1862 cable.
[0256] In the mode shown, the waveguide systems 18 65'-1 and 18 65'-2 are each in a configuration that is perpendicular to the longitudinal geometric axis of the 1862 cable and the wave direction, and so that a plane that contains the radiation elements of the MMIC 1870 is parallel to a plane that contains the radiation elements of the MMIC 1870 ', however, other configurations are similarly possible. In several modalities, the distance d5 between the waveguides 1865'-1 and 1865'-2 corresponds to the distance between the planes of the radiation elements of the MMIC 1870 and 1870 '. The distance d5 can be adjusted or otherwise defined to support the induction of propagation of electromagnetic waves 18 68 through a selected non-fundamental or fundamental wave mode, such as TMoo, HEn, EHi _m , TMom, (where m = 1 , 2,...) Or other non-fundamental and / or asymmetric modes at a chosen operating frequency. For example, the distance d5 can be adjusted incrementally to determine the particular value of d5
Petition 870190094101, of 9/19/2019, p. 144/263
138/206 which yields the highest signal strength in one or more selected modes of the 1868 electromagnetic waves.
[0257] In several modalities, the 1865'-2 waveguide system has a reflective plate 1871 in a region behind the radiation elements of the MMIC 1870 'in relation to the direction of propagation of the electromagnetic waves 1868. The reflective plate can be constructed of metallic plate, a metallic coated surface, a mesh of fiber that has a sufficient density to reflect electromagnetic waves that move towards the reflective plate 1871 from the MMIC 1870 ', or other reflective plates.
[0258] In operation, the reflective plate 1871 assists in directing the instances of electromagnetic waves 1861 'to an interface of a transmission medium, such as the surface of the cable 1862, to induce the propagation of the electromagnetic waves 1868 along the cable 1862 - propagation does not require an electrical return path. For example, the reflective plate 1871 can be reduced to the ground and / or the outer housing of the waveguide system 18 65 to interact with the 1861 e-fields generated by the MMIC.
[0259] In the modality shown, the reflective plate 1871 is positioned inside the outer housing of the 1865'-2 waveguide system in a configuration that is perpendicular to the longitudinal geometric axis of the cable 18 62 and the wave direction, and optionally is parallel to a plane containing the radiation elements of the MMIC 1870 ', however, other configurations are similarly possible. In different modalities, the distance d6 between the reflective plate and the radiation elements of the MMIC 1870 can be adjusted or adjusted.
Petition 870190094101, of 9/19/2019, p. 145/263
139/206 another mode defined to support the induction of the propagation of 1868 electromagnetic waves through a selected non-fundamental or fundamental wave mode, such as TMoo, HEn, EHim, TMom, (where m = 1, 2,...) or other non-fundamental and / or asymmetric mode at a chosen operating frequency. For example, the distance d6 can be adjusted incrementally to determine the particular value of d6 that yields the highest signal strength of one or more selected modes of the 1868 electromagnetic waves. Additionally, the selection of angular displacements of the MMIC 1870 from each other and the angular shifts of MMIC 1870 together with the phase shifts of signal input 1872 generated by each circuit can be used in addition to distances d6 and distance d5 to support a non-fundamental wave mode of electromagnetic waves 1868 with a desired spatial orientation.
[0260] Although not expressly shown, a conductive horn or other coaxial reflector can be added to the 18 65'-1 waveguide system to assist in directing the 1861 e-fields to induce 1868 electromagnetic waves on the 1862 cable. In addition, although not expressly shown, a housing, or radome, may be provided between 1865'-1 and 1865'-2 waveguide systems to protect the launcher from the environment and / or to reduce emissions and additionally direct 1861 electromagnetic waves 'for cable 1862 or 1852.
[02 61] In another embodiment, the 1865'-1 and 1865'-2 waveguide systems in Figure 18V can also be configured to generate electromagnetic waves that have
Petition 870190094101, of 9/19/2019, p. 146/263
140/206 only non-fundamental wave modes. This can be accomplished by adding more MMIC 1870 and 1870 'as shown in Figure 18W. In particular, a concentric alignment of MMIC 1870 of the waveguide system 1865'-1 is presented together with the concentric alignment of MMIC 1870 'of the waveguide system 1865'-2 behind.
[0262] Each MMIC 1870 and 1870 'can be configured to receive the same signal input 1872. However, the MMIC 1870 can be selectively configured to emit electromagnetic waves that have different phases using the set of controllable phase shift circuits in each MMIC 1870 and 1870 '. For example, the d5 distance can be defined in an integer number of wavelengths and the MMIC 1870 to the north and south can be configured to emit electromagnetic waves that have a 180 degree phase difference, thus aligning the e-fields in a north or south direction. Any combination of pairs of MMIC 1870 and 1870 '(for example, MMIC 1870 to the west and east, MMIC 1870' to the northwest and southeast, MMIC 1870 'to the northeast and southwest) can be configured with opposite or aligned e-fields. Consequently, the 1865 'waveguide system can be configured to generate electromagnetic waves with one or more non-fundamental wave modes, electromagnetic waves with one or more fundamental wave modes or any combinations thereof.
[0263] Not all MMICs need to be broadcasting at any given time. A single MMIC 1870 or 1870 'among the MMIC 1870 and 1870' shown in Figure 18W can be configured to generate electromagnetic waves that have a
Petition 870190094101, of 9/19/2019, p. 147/263
141/206 non-fundamental wave mode, while all other MMIC 1870 and 1870 'are not in use or are disabled. Similarly, other wave modes and wave mode combinations can be induced by enabling other suitable non-zero subgroups of MMIC 1870 and 1870 'with controllable phases.
[0264] It is further noted that, in some embodiments, the waveguide systems 1865, 1865 'and 1865' 'of Figures 18N to 18W can generate combinations of fundamental and non-fundamental wave modes in which one wave mode is dominant about the other. For example, in one embodiment, the electromagnetic waves generated by the waveguide systems 1865, 1865 'and 1865' 'of Figures 18N to 18W may have a weak signal component that has a non-fundamental wave mode, and a component of substantially strong signal that has a fundamental wave mode. Thus, in this modality, electromagnetic waves have a substantially fundamental wave mode. In another embodiment, the electromagnetic waves generated by the waveguide systems 1865, 1865 'and 1865' 'of Figures 18N to 18W may have a weak signal component that has a fundamental wave mode, and a substantially strong signal component which has a non-fundamental wave mode. Thus, in this mode, electromagnetic waves have a substantially non-fundamental wave mode. In addition, a non-dominant wave mode can be generated, which propagates only trivial distances along the length of the transmission medium.
[0265] It is also noted that the waveguide systems 1865, 1865 'and 1865' 'of Figures 18N to 18W can be
Petition 870190094101, of 9/19/2019, p. 148/263
142/206 configured to generate instances of electromagnetic waves that have wave modes that may differ from one mode or modes resulting from the combined electromagnetic wave. It is further noted that each MMIC 1870 or 1870 'of the 1865' waveguide system of Figure 18W can be configured to generate an instance of electromagnetic waves that have wave characteristics that differ from the wave characteristics of another instance of electromagnetic waves generated by another MMIC 1870 or 1870 '. An 1870 or 1870 'MMIC, for example, can generate an instance of an electromagnetic wave having a spatial orientation and a phase, frequency, magnitude, electric field orientation and / or magnetic field orientation that differ from the spatial orientation and phase, frequency , magnitude, electric field orientation and / or magnetic field orientation of an instance different from another electromagnetic wave generated by another MMIC 1870 or 1870 '. The 1865 'waveguide system can thus be configured to generate instances of electromagnetic waves having different wave and spatial characteristics, which when combined achieve the resulting electromagnetic waves having one or more desirable wave modes.
[0266] From these illustrations, it is submitted that the waveguide systems 1865 and 1865 'of Figures 18N to 18W can be adapted to generate electromagnetic waves with one or more selectable wave modes. In one embodiment, for example, waveguide systems 1865 and 1865 'can be adapted to select one or more wave modes and generate electromagnetic waves having a single wave mode or multiple wave modes selected and produced from
Petition 870190094101, of 9/19/2019, p. 149/263
143/206 of a process of combining instances of electromagnetic waves having one or more configurable wave and spatial characteristics. In one mode, for example, parametric information can be stored in a lookup table. Each entry in the lookup table can represent a selectable wave mode. A selectable wave mode can represent a single wave mode or a combination of wave modes. The combination of wave modes can have one or more dominant wave modes. Parametric information can provide configuration information to generate instances of electromagnetic waves to produce resulting electromagnetic waves that have the desired wave mode.
[0267] For example, once a wave mode or modes is selected, the parametric information obtained from the lookup table of the entry associated with the selected wave mode (or modes) can be used to identify which one or more MMIC 1870 and 1870 'use and / or their corresponding configurations to reach electromagnetic waves that have the desired wave mode (or modes). Parametric information can identify the selection of one or more MMIC 1870 and 1870 'based on the spatial orientations of MMIC 1870 and 1870', which may be necessary for the production of electromagnetic waves with the desired wave mode. Parametric information can also provide information to configure each one of the one or more MMIC 1870 and 1870 ', with a phase, frequency, magnitude, electric field orientation and / or particular magnetic field orientation that may or may not be the same for each one of the MMIC

144/206
1870 or 1870 'selected. A lookup table with selectable wave modes and corresponding parametric information can be adapted to configure the waveguide system 1865, 1865 'and 1865' '.
[0268] In some embodiments, a guided electromagnetic wave can be considered to have a desired wave mode if the corresponding wave mode propagates non-trivial distances in a transmission medium, and has a field strength that is substantially greater in magnitude ( for example, 20 dB greater in magnitude) than other wave modes that may or may not be desirable. Such a desired wave mode or modes can be termed as the dominant wave mode (or modes), with the other wave modes being termed as non-dominant wave modes. Similarly, a guided electromagnetic wave that is said to be substantially without the fundamental wave mode, has no fundamental wave mode or has a non-dominant fundamental wave mode. A guided electromagnetic wave that is said to be substantially without a non-fundamental wave mode, has no non-fundamental wave mode (or modes) or has only non-dominant non-fundamental wave mode (or modes). In some embodiments, a guided electromagnetic wave, which is said to have only a single wave mode or a selected wave mode, may have only one corresponding dominant wave mode.
[0269] It is further noted that the modalities of Figures 18U to 18W can be applied to other modalities for the dissemination of the matter. For example, the modalities of Figures 18U to 18W can be used as alternative modalities to the modalities represented in Figures 18N a
Petition 870190094101, of 9/19/2019, p. 151/263
145/206
18T or can be combined with the modalities shown in Figures 18N to 18T.
[0270] Turning now to Figures 18X and 18Z, the block diagrams illustrating example non-limiting modalities of a dielectric antenna and corresponding plots of field strength and gain according to various aspects described in this document are shown . Figure 18X represents an 1891 dielectric horn antenna having a conical structure. The 1891 dielectric horn antenna is coupled to an 1892 power point, which can also be comprised of a dielectric material. In one embodiment, for example, the dielectric horn antenna 1891 and the supply point 1892 can be constructed of dielectric materials such as a polyethylene material, a polyurethane material or other suitable dielectric materials (for example, a synthetic resin). In one embodiment, the 1891 dielectric horn antenna and the 1892 power point can be adapted to be devoid of any conductive materials. For example, the external surfaces 1897 of the 1891 dielectric horn antenna and 1892 power point may be non-conductive and the dielectric materials used to construct the 1891 dielectric antenna and 1892 power point may be so that they substantially do not contain impurities that can be conductive.
[0271] The supply point 1892 '' can be adapted to be coupled to a core 1852 as previously described by way of illustration in Figures 181 and 18J. In one embodiment, the 1892 '' power point can be
Petition 870190094101, of 9/19/2019, p. 152/263
146/206 coupled to the core 1852 using a joint (not shown in Figure 18X), such as, for example, the 1860 joint device of Figure 18J. Other arrangements for coupling the 1892 '' power point to the 1852 core can be used. In one embodiment, the joint can be configured to cause the 1892 '' feed point to touch an end point of the 1852 core. In another embodiment, the joint can create a gap between the 1892 '' feed point and the end of core 1852. In yet another embodiment, the joint can cause the 1892 '' feed point and the 1852 core to be coaxially aligned or partially misaligned. Despite any combination of the previous modes, electromagnetic waves can, in whole or at least in part, propagate between the junction of the 1892 '' power point and the 1852 core.
[0272] The 1850 cable can be coupled to the 1865 waveguide system shown in Figure 18S or to the 1865 'waveguide system shown in Figure 18T. For the purposes of illustration only, reference will be made to the 1865 'waveguide system of Figure 18T. However, it is understood that the 1865 waveguide system of Figure 18S can also be used according to the discussions that follow. The 18 65 'waveguide system can be configured to select a wave mode (for example, non-fundamental wave mode, fundamental wave mode, a hybrid wave mode or combinations thereof as described above) and transmit instances of electromagnetic waves having a non-optical operating frequency (for example, 60 GHz). Electromagnetic waves can be
Petition 870190094101, of 9/19/2019, p. 153/263
147/206 directed to an 1850 cable interface as shown in Figure 18T.
[0273] The instances of electromagnetic waves generated by the 18 65 'waveguide system can induce a combined electromagnetic wave having the selected wave mode that propagates from the 1852 core to the 1892' 'power point. The combined electromagnetic wave can propagate partly within the 1852 core and partly on an outer surface of the 1852 core. Since the combined electromagnetic wave was propagated through the junction between the 1852 core and the 1892 power point, the electromagnetic wave combined may continue to propagate partly within the 1892 feed point and partially on an outer surface of the 1892 feed point. In some embodiments, the portion of the combined electromagnetic wave that propagates on the outer surface of the 1852 core and the feed point 1902 is small. In these modalities, the combined electromagnetic wave can be considered to be firmly coupled to the 1852 core and the 1892 power point while propagating longitudinally towards the 1891 dielectric antenna.
[0274] When the combined electromagnetic wave reaches a proximal portion of the dielectric antenna 1891 (at a junction 1892 'between the 1892 power point and the dielectric antenna 1891), the combined electromagnetic wave enters the proximal portion of the dielectric antenna 1891 and propagates longitudinally along a geometric axis of the 1891 dielectric antenna (shown as a dashed line). When
Petition 870190094101, of 9/19/2019, p. 154/263
148/206 the combined electromagnetic wave reaches orifice 1893, the combined electromagnetic wave has a pattern of intensity similar to that shown in Figure 18Y. The pattern of electric field strength in Figure 18Y shows that the electric fields of the combined electromagnetic waves are the strongest in a central region of passage 1893 and weakest in the outer regions. In one embodiment, when the wave mode of electromagnetic waves propagating on the dielectric antenna 18 91 is a hybrid wave mode (for example, HE11), the leakage of electromagnetic waves on external surfaces 1897 is reduced or, in some cases, eliminated . Methods for launching a hybrid wave mode on an 1850 cable are discussed below.
[0275] In one embodiment, the far-field antenna gain pattern shown in Figure 18Y can be extended by decreasing the operating frequency of the combined electromagnetic wave. Similarly, the gain pattern can be reduced by increasing the operating frequency of the combined electromagnetic wave. Consequently, a width of a beam of wireless signals emitted through hole 1893 can be controlled by configuring the waveguide system 1865 'to increase or decrease the operating frequency of the combined electromagnetic wave.
[0276] The 1891 dielectric antenna of Figure 18X can also be used to receive wireless signals. The wireless signals received by the dielectric antenna 1891 in hole 1893 induce electromagnetic waves in the dielectric antenna 1891 that propagate towards the 1892 power point. The electromagnetic waves continue to propagate from the point of

149/206 supply 1892 to core 1852, and are thus delivered to the waveguide system 1865 'coupled to the cable 1850 as shown in Figure 18T. In this configuration, the 1865 'waveguide system can perform bidirectional communications using the 1891 dielectric antenna. It is also noted that, in some embodiments, the 1852 core of the 1850 cable (shown with dashed lines) can be configured to be collinear with the 1892 '' power point to avoid a curve shown in Figure 18X. In some modalities, a
collinear configuration can reduce an change gives electromagnetic due to curve on cable 1 850. [0277] With reference now The figure 18Z, is shown one block diagram a modality not limiting in
example of another dielectric antenna structure according to several aspects described here. Figure 18Z represents an array of 1894 pyramid-shaped dielectric horn antennas. Each antenna in the 1894 pyramid-shaped dielectric horn antenna array may have an 18 96 power point that attaches to an 1852 core of a plurality of 1850 cables. Each 1850 cable can be attached to a different 1865 'waveguide system, as shown in Figure 18T. The 1894 pyramid-shaped dielectric antenna array can be used to transmit wireless signals having a plurality of spatial orientations. An array of dielectric horn antennas in 1894 pyramidal shape covering 360 degrees can allow a plurality of 18 65 'waveguide systems coupled to the antennas to perform omnidirectional communications with other similar communication devices or antennas.
Petition 870190094101, of 9/19/2019, p. 156/263
150/206 [0278] The bidirectional propagation properties of electromagnetic waves previously described for the 1891 dielectric antenna of Figure 18X are also applicable for electromagnetic waves that propagate from the 1852 core to the 1896 feed point for the 1895 antenna hole 1894 pyramid shaped dielectric horn and in the reverse direction. Similarly, the 1894 pyramid-shaped dielectric antenna array may lack conductive surfaces and internal conductive materials. For example, in some embodiments, the 1894 pyramid-shaped dielectric horn antenna array and its corresponding 1896 power points can be constructed of only dielectric materials, such as polyethylene or polyurethane materials.
[0279] It is further noted that each antenna in the 1894 pyramid shaped dielectric horn antenna array may have similar electric field strength and gain maps as shown for the 1891 dielectric antenna in Figure 18Y. Each antenna of the 1894 pyramid-shaped dielectric horn array can also be used for receiving wireless signals as previously described for the 1891 dielectric antenna of Figure 18X. In some embodiments, a single instance of a pyramid-shaped dielectric horn antenna can be used. Similarly, multiple instances of the 1891 dielectric antenna of Figure 18X can be used in a matrix configuration similar to that shown in Figure 18Z.
[0280] Turning now to Figures 19A and 19B, block diagrams are shown that illustrate non-modalities
Petition 870190094101, of 9/19/2019, p. 157/263
151/206 example limitations of the 1850 cable of Figure 18A used for the induction of guided electromagnetic waves on power lines supported by electricity poles. In one embodiment, as shown in Figure 19A, an 1850 cable can be attached at one end to a microwave device that launches guided electromagnetic waves into one or more inner layers of the 1850 cable using, for example, the hollow waveguide 1808 shown in Figures 18A to 18C. The microwave device can use a microwave transceiver, as shown in Figure 10A, for the transmission or reception of signals from the 1850 cable. Guided electromagnetic waves induced in one or more internal layers of the 1850 cable can propagate up to an exposed stub of cable 1850 located inside a horn antenna (shown as a dotted line in Figure 19A) for radiation from electromagnetic waves via the horn antenna. The signals radiated from the horn antenna can, in turn, induce guided electromagnetic waves that propagate longitudinally on a medium voltage (MV) power line. In one embodiment, the microwave device can receive AC power from a low voltage power line (for example, 220 V). Alternatively, the horn antenna can be replaced with a stub antenna as shown in Figure 19B to induce guided electromagnetic waves that propagate longitudinally on the MV power line or to transmit wireless signals to another antenna system (or systems).
[0281] In an alternative embodiment, the hollow horn antenna shown in Figure 19A can be replaced by a
Petition 870190094101, of 9/19/2019, p. 158/263
152/206 solid dielectric antenna, such as, for example, the 1891 dielectric antenna of Figure 18X, or the 1894 pyramidal horn antenna of Figure 18Z. In this modality, the horn antenna can radiate wireless signals directed to another horn antenna, such as the 1940 bi-directional horn antennas shown in Figure 19C. In this embodiment, each 1940 horn antenna can transmit wireless signals to another 1940 horn antenna or receive wireless signals from the other 1940 horn antenna as shown in Figure 19C. This arrangement can be used to perform bidirectional wireless communications between antennas. Although not shown, the 1940 horn antennas can be configured with an electromechanical device to orient a direction of the 1940 horn antennas.
[0282] In alternative modes, the first and second cables 1850A 'and 1850B' can be coupled to the microwave device and a 1952 transformer, respectively, as shown in Figures 19A and 19B. The first and second cables 1850A 'and 1850B' can be represented, for example, by the cable 1820 or the cable 1830 of Figures 18B and 18C, respectively, each having a conductive core. A first end of the conductive core of the first cable 1850A 'can be coupled to the microwave apparatus for the propagation of guided electromagnetic waves launched there. A second end of the conductive core of the first cable 1850A 'can be coupled to a first end of a conductor coil of the 1952 transformer for the reception of the guided electromagnetic waves propagating in the first cable 1850A' and for the provision of signals there associated with
Petition 870190094101, of 9/19/2019, p. 159/263
153/206 a first end of a second cable 1850B 'via a second end of the conductive coil of transformer 1952. A second end of the second cable 1850B' can be coupled to the horn antenna of Figure 19A or can be exposed as an antenna of Figure 19B stub for the induction of guided electromagnetic waves that propagate longitudinally in the MV power line.
[0283] In an embodiment where each cable 1850, 1850A 'and 1850B' comprises multiple instances of 1800, 1820 and / or 1830 transmission means, an antenna 1855 poly-rod structure can be formed as shown in Figure 18K. Each 1855 antenna can be coupled, for example, to a set of horn antennas as shown in Figure 19A or a set of dish antennas (not shown) for radiation from multiple wireless signals. Alternatively, 1855 antennas can be used as stub antennas in Figure 19B. The microwave apparatus of Figures 19A and 19B can be configured to adjust the guided electromagnetic waves to orient the beam of the wireless signals emitted by the 1855 antennas. One or more of the 1855 antennas can also be used for the induction of guided electromagnetic waves on a power line.
[0284] Now moving to Figure 19C, a block diagram of a non-limiting example of a 1900 communication network is shown according to various aspects described here. In one embodiment, for example, the waveguide system 1602 of Figure 16A can be incorporated into network interface (NID) devices, such as, for example, NID 1910 and 1920 of Figure 19C. An NID having the
Petition 870190094101, of 9/19/2019, p. 160/263
154/206 functionality of the 1602 waveguide system can be used to improve transmission capabilities between 1902 customer facilities (business or residential) and a 1904 base (sometimes referred to as a service area interface or SAI).
[0285] In one embodiment, a 1930 central office can provide one or more 1926 fiber cables based on 1904. 1926 fiber cables can provide high-speed full-duplex data services (for example, 1 to 100 Gbps or higher ) the mini-DSLAM 1924 located at base 1904. Data services can be used to transport voice services, Internet traffic, media content services (for example, streaming video services, open TV), and so on. onwards. In state-of-the-art systems, 1924 mini-DSLAM typically connect to twisted pair telephone lines (for example, twisted pairs included in Category 5e or Cat. 5e unshielded twisted pair (UTP) cables that include a non-bundled bundle) shielded of twisted pair cables, such as, for example, 24 gauge insulated solid wires, surrounded by an outer insulation cap), which in turn connect directly to the 1902 customer premises. On these systems, DSL data rates gradually decrease by 100 Mbps or less due, in part, to the length of legacy twisted pair cables for the 1902 customer facility, among other factors.
[0286] The modalities of Figure 19C, however, are distinct from the state-of-the-art DSL systems. In the illustration in Figure 19C, a 1924 mini-DSLAM, for example, can be configured to connect to the 1920 NID via the
Petition 870190094101, of 9/19/2019, p. 161/263
155/206 cable 1850 (which can represent all or part of any of the cable modalities described in relation to Figures 18A to 18D and 18F to 18L alone or together). The use of the 1850 cable between customer installations 1902 and a base 1904 allows the NIDs 1910 and 1920 to transmit and receive guided electromagnetic waves for uplink and downlink communications. Based on the previously described modalities, the 1850 cable can be exposed to rain, or it can be buried without adversely affecting the propagation of electromagnetic waves in a downlink path or an uplink path, as long as the electric field profile of these waves in either direction it is confined at least in part or entirely within the inner layers of the 1850 cable. In the present illustration, downlink communications represent a communication path from base 1904 to client facilities 1902, while uplink communications represent a communication path from customer facilities 1902 to base 1904. In an embodiment in which the 1850 cable comprises one of the modalities of Figures 18G and 18H, the 1850 cable can also serve the purpose of providing power to the NID 1910 and 1920 and other equipment from customer 1902 and base 1904.
[0287] At the 1902 customer premises, DSL signals may come from a 1906 DSL modem (which may have a built-in router and which can provide wireless services, such as WiFi, to user equipment shown at the customer's premises 1902). DSL signals can be provided to NID 1910 by a 1908 twisted pair telephone.
Petition 870190094101, of 9/19/2019, p. 162/263
156/206
The NID 1910 can use the integrated waveguide 1602 to launch inside the cable 1850 guided electromagnetic waves 1914 directed to the base 1904 in an uplink path. On the downlink path, DSL signals generated by the 1924 mini-DSLAM can travel over a 1922 twisted pair telephone line up to NID 1920. The 1602 waveguide system integrated in NID 1920 can convert DSL signals, or a portion of them, of the electrical signals in guided electromagnetic waves 1914 that propagate inside the cable 1850 in the downlink path. To provide full-duplex communications, the 1914 uplink guided electromagnetic waves can be configured to operate on a different carrier frequency and / or a different modulation approach compared to the 1914 uplink guided electromagnetic waves to reduce or avoid the interference. Additionally, in the uplink and downlink paths, the guided electromagnetic waves 1914 are guided by a core section of the cable 1850, as previously described, and these waves can be configured to have a field strength profile that confines the electromagnetic waves guided in whole or in part in the inner layers of the 1850 cable. Although the 1914 guided electromagnetic waves are shown outside the 1850 cable, the representation of these waves is for illustration purposes only. For this reason, the guided electromagnetic waves 1914 are designed with hashes to indicate that they are guided by the inner layers of the 1850 cable.
Petition 870190094101, of 9/19/2019, p. 163/263
157/206 [0288] On the downlink path, the NID 1910's 1602 integrated waveguide system receives the 1914 guided electromagnetic waves generated by the NID 1920 and converts them back into DSL signals in accordance with DSL modem requirements 1906. DSL signals are then provided to the 190 6 DSL modem via a 1908 telephone line twisted pair wire for processing. Similarly, on the uplink path, the integrated waveguide system 1602 of the NID 1920 receives the guided electromagnetic waves 1914 generated by the NID 1910 and converts them back into DSL signals in accordance with the requirements of the mini-DSLAM 1924. The DSL signals are then provided to the 1924 mini-DSLAM via a 1922 telephone line twisted pair wire for processing. Due to the short length of telephone lines 1908 and 1922, the DSL modem 1908 and mini-DSLAM 1924 can send and receive DSL signals with each other on the uplink and downlink at very high speeds (for example, 1 Gbps to 60 Gbps or more). Consequently, the uplink and downlink paths can, in most circumstances, exceed the data rate limits of traditional DSL communications on twisted-pair telephone lines.
[0289] Typically, DSL devices are configured for asymmetric data rates, since the downlink path usually supports a higher data rate than the uplink path. However, the 1850 cable can provide much higher speeds on both the downlink and uplink paths. With one
Petition 870190094101, of 9/19/2019, p. 164/263
158/206 firmware update, a legacy DSL 1906 modem, as shown in Figure 19C, can be configured with higher speeds on both the downlink and uplink paths. Similar firmware upgrades can be performed on the 1924 mini-DSLAM to take advantage of higher speeds on the uplink and downlink paths. Since the interfaces for the DSL 1906 and mini-DSLAM 1924 modem remain like traditional twisted-pair telephone lines, no hardware changes are required for a legacy DSL or mini-DSLAM modem beyond the firmware changes and the addition NID 1910 and 1920 to convert DSL signals into guided electromagnetic waves 1914 and vice versa. The use of NID allows you to reuse legacy 1906 modems and 1924 mini-DSLAM, which in turn can substantially reduce installation costs and system upgrades. For the new construction, updated versions of mini-DSLAM and DSL modems can be configured with integrated waveguide systems to perform the functions described above, thus eliminating the need for NID 1910 and 1920 with integrated waveguide systems. In this modality, an updated version of the 1906 modem and an updated version of the 1924 mini-DSLAM would connect directly to the 1850 cable and communicate via bidirectional guided electromagnetic wave transmissions, thus avoiding a need for transmitting or receiving DSL signals using lines twisted pair telephone lines 1908 and 1922.
[0290] In a modality where the use of the 1850 cable between the base 1904 and the facilities of the customer 1902 is logistically
Petition 870190094101, of 9/19/2019, p. 165/263
159/206 impractical or expensive, the NID 1910 can be configured as an alternative to be coupled to an 1850 'cable (similar to the 1850 cable in the disclosure under discussion) coming from a waveguide 108 on an electricity pole 118, and which can be buried in the ground before reaching NID 1910 from customer facilities 1902. Cable 1850 'can be used to receive and transmit guided electromagnetic waves 1914' between NID 1910 and waveguide 108. waveguide 108 can be connect via waveguide 106, which can be coupled to base station 104. Base station 104 can provide data communication services to customer facilities 1902 by connecting to headquarters 1930 via fiber 1926 ' . Similarly, in situations where access from central office 1926 to base 1904 is not feasible via a fiber link, but connectivity to base station 104 is possible via fiber link 1926 ', an alternate path to the connection to the NID 1920 of base 1904 via cable 1850 '' (similar to cable 1850 of the disclosure under discussion) from post 116. Cable 1850 '' can also be buried before reaching NID 1920.
[0291] Figures 20A and 20B describe modalities for downlink and uplink communications. The 2000 method of Figure 20A can begin with step 2002 in which electrical signals (for example, DSL signals) are generated by a DSLAM (for example, 1924 mini-DSLAM from base 1904 or from headquarters 1930), which are converted in 1914 electromagnetic waves guided in stage 2004 by the NID 1920 and that propagate in a transmission medium such as, for example,
Petition 870190094101, of 9/19/2019, p. 166/263
160/206 cable 1850, for the provision of downlink services to customer facilities 1902. In step 2008, NID 1910 of customer facilities 1902 converts guided electromagnetic waves 1914 back into electrical signals (for example, DSL signals ) that are provided in step 2010 to the customer facilities equipment (CPE), such as, for example, DSL modem 1906, over the telephone line 1908. Alternatively, or together, the power and / or the guided electromagnetic waves 1914 'can be provided with a power line 1850 'from a public network (having an inner waveguide as illustrated in Figures 18G or 18H) to NID 1910 as an alternative or additional downlink path (and / or uplink).
[0292] In step 2022 of the 2020 method of Figure 20B, the DSL modem 1906 can provide electrical signals (for example, DSL signals) via telephone line 1908 to NID 1910, which in turn in step 2024 converts DSL signals into guided electromagnetic waves directed to NID 1920 via cable 1850. In step 2028, NID 1920 from base 1904 (or headquarters 1930) converts guided electromagnetic waves 1914 back into electrical signals (for example, DSL signals) that are provided in step 2029 to a DSLAM (e.g., mini-DSLAM 1924). Alternatively, or together, the power and guided electromagnetic waves 1914 'can be provided with a power line 1850' from a public network (having an inner waveguide as illustrated in Figures 18G or 18H) to the NID 1920 as a alternative or additional uplink path (and / or downlink).

161/206 [0293] Now moving on to Figure 20C, a flowchart of a non-limiting example of a 2030 method for the induction and reception of electromagnetic waves in a transmission medium is shown. In step 2032, waveguides 1865 and 1865 'of Figures 18N to 18T can be configured to generate first electromagnetic waves from a first communication signal (provided, for example, by a communication device), and induce in step 2034 the first electromagnetic waves with only one fundamental wave mode at a transmission medium interface. In one embodiment, the interface may be an outer surface of the transmission medium as shown in Figures 18Q and 18R.

162/206 [0294] Moving now to Figure 20D, a 2040 block diagram of a non-limiting example of a communication system is shown, according to several aspects described here. In particular, a communication system is shown that includes a 2042 transmitter and an intelligent launcher that includes an impedance matching circuit 2044, a guided wave launcher 2046, a mismatch probe 2050 and a controller 2054.
[0295] In several modalities, the transmitter generates an incoming RF signal 2043 to be converted by the guided wave launcher 204 6 into a guided electromagnetic wave 2048 that is launched in the transmission medium 125. The incoming RF signal 2043 can be on a millimeter wave or other microwave frequency bands and can be modulated to conduct data to a similar receiver coupled to a remote smart launcher 2049 that extracts the guided electromagnetic wave 2048 from the 125 transmission medium. impedance 2044 provides an impedance adaptation (for example, to reduce the amount of mismatch impedance) between the 2042 transmitter and the guided wave launcher 2046 to reduce reflected signal energy from the guided wave launcher 2046 and / or to increase the flow of power from the 2042 transmitter to the 2046 guided wave launcher. In operation, the impedance adaptation circuit 2044 receives the incoming RF signal to 2043 and generates an output RF signal 2045 in response to the input RF signal 2043. The impedance matching circuit 2044 includes one or more adjustable circuit elements and is dynamically tunable for different impedances.
Petition 870190094101, of 9/19/2019, p. 169/263
163/206
Although impedance matching circuit 2044 is shown separate from transmitter 2042 and guided wave launcher 2046, some or all components of the impedance adaptation circuit can be implemented in transmitter 2042 and / or guided wave launcher 2046.
[0296] The guided wave launcher 2046 is configured to generate, in response to the output RF signal 2045, a guided electromagnetic wave 2048 along a surface of a 125 transmission medium. The guided electromagnetic wave propagates along the surface of the transmission medium without requiring an electrical return path, and has a non-optical carrier frequency, which corresponds to the carrier frequency of the incoming RF signal 2043 generated by the 2042 transmitter. In several embodiments, the guided wave launcher 204 6 can be implemented using any of the launcher designs previously discussed here or through another bugle launcher, another non-coaxial launcher, a tapered groove, ribbon line, microfiche or other flat launcher, an antenna , magnetic coupler, capacitive coupler and / or other launcher design.
[0297] The 2050 mismatch probe is configured to generate a 2052 mismatch signal based on the 2045 output RF signal, where the 2052 mismatch signal indicates an impedance mismatch of the guided wave launcher 2046. For example, the probe of mismatch 2050 is implemented by means of an envelope detector, sampling and retention circuit or other voltage detectors that detect the envelope or peak voltage of the RF signal
Petition 870190094101, of 9/19/2019, p. 170/263
164/206 output 2045. In other examples, the 2050 mismatch probe can be implemented by means of a standing wave ratio meter, a directional coupler and / or a reflectometer that measures a voltage signal standing wave ratio. Output RF 2045 or reflected voltage from the guided wave launcher 2046 back to the impedance matching circuit 2044.
[0298] Controller 2054 is configured to generate one or more control signals 2056 in response to the mismatch signal, where one or more control signals 2056 adjust one or more adjustable circuit elements of the impedance adaptation circuit 2044 to facilitate the reduction of the impedance mismatch of the guided wave launcher 2046. In several embodiments, the impedance adaptation circuit 2044 can be configured as a pi network, an L network or a T network that includes one or more adjustable impedances, such as adjustable inductors and / or capacitors. The 2054 controller generates individual 2056 control signals to adjust the impedance of each of the adjustable inductors and / or capacitors to reduce mismatch. In another embodiment, the impedance matching circuit 2044 includes a tunable transformer, such as an adjustable impedance matching balun or other adapting transformers that provide broadband impedance matching.
[0299] Controller 2054 can be implemented by means of a single 2053 processing device or a plurality of processing devices. Such a 2053 processing device can be a
Petition 870190094101, of 9/19/2019, p. 171/263
165/206 microprocessor, microcontroller, digital signal processor, microcomputer, central processing unit, field programmable port arrangement, programmable logic device, state machine, logic circuit set, analog circuit set, digital circuit set and / or any device that manipulates signals (analog and / or digital) based on rigid encoding of the circuitry and / or operating instructions. Controller 2054 may be, or additionally include, memory and / or an integrated memory element, which may be a single memory device, a plurality of memory devices and / or an embedded circuitry from another processing module, module, processing circuit and / or processing unit. Such a memory device can be read-only memory, random access memory, volatile memory, non-volatile memory, static memory, dynamic memory, flash memory, cache memory and / or any device that stores digital information. Note that if the 2054 controller includes more than one processing device, the processing devices can be centrally located (for example, directly coupled together via a wired and / or wireless bus structure) or can be located in a distributed manner (for example, cloud computing through indirect coupling through a local area network and / or a wide area network). It is also noted that, if the 2054 controller implements one or more of its functions through a state machine, analog circuitry,
Petition 870190094101, of 9/19/2019, p. 172/263
166/206 digital circuitry and / or logic circuitry, the memory and / or memory element that stores the corresponding operating instructions can be incorporated into, or external to, the circuitry comprising the state machine , set of analog circuits, set of digital circuits and / or set of logic circuits. It is also noted that the memory element can store, and the 2054 controller executes, rigid code and / or operating instructions that correspond at least to some of the steps and / or functions described here. Such a memory device or memory element can be included in an article of manufacture.
[0300] In several modalities, the memory of the controller 2054 includes a lookup table (LUT) 2055 that is indexed by possible values of the mismatch signal 2052 and includes corresponding values of the control signal (s) 2056 that it controls ( m) the 2044 adjustable circuit elements to desired values to compensate and / or reduce the impedance mismatch of the 2046 guided wave launcher. In other embodiments, the 2054 controller can operate by means of a control algorithm to calculate the values of the control signals directly based on the amount of mismatch indicated by the mismatch signal or can by means of a search algorithm, such as a gradient search algorithm that responds to changes in the mismatch signal by searching for values of the 2056 control signals until the 2052 mismatch signal indicates that an acceptable impedance mismatch level has been reached, or otherwise
Petition 870190094101, of 9/19/2019, p. 173/263
167/206 that the impedance mismatch has been reduced as much as possible.
[0301] Consider a specific example where the guided wave launcher 2046 is implemented by means of a tapered horn antenna and the guided electromagnetic wave 2048 is modulated by means of a broadband modulation signal over a frequency range 3 to 6 GHz in an outdoor transmission medium 125, such as a medium voltage power line from an electrical power service. The guided wave launcher 2046 has an impedance that changes based on weather conditions in an area of the transmission medium 125 such as rain, sleet, snow, dew, etc. Controller 2054 generates control signals 2056 to adjust the one or more adjustable circuit elements of the impedance matching circuit 2044 to compensate for the change in impedance based on the climatic condition in the area of the transmission medium. For example, the 2044 impedance matching circuit may include an adjustable impedance matching transformer that provides broadband impedance matching from the 2042 transmitter to the 2046 guided wave launcher and the 2054 controller generates a 2056 control signal to control the impedance adaptation by the adjustable impedance adaptation transformer to reduce the mismatch caused by changes in weather conditions.
[0302] Now moving on to Figures 20E to 20G, block diagrams 2058, 2060 and 2062 and non-limiting examples of an impedance adaptation circuit 2044 are shown, according to various aspects
Petition 870190094101, of 9/19/2019, p. 174/263
168/206 described herein. In particular, the impedance matching circuit 2044 is shown in diagram 2058 in a T network configuration with impedances Za, Zb and Zc. One or more of these three impedances can be implemented by means of an adjustable capacitor or inductor with the remaining impedances, if any, being implemented by means of fixed impedance, such as a fixed capacitor or inductor. The impedance matching circuit 2044 is shown in diagram 2060 in a Pi network configuration with impedances Za, Zb and Zc. One or more of these three impedances can be implemented by means of an adjustable capacitor or inductor with the remaining impedances, if any, being implemented by means of fixed impedance, such as a fixed capacitor or inductor. The impedance adaptation circuit 2044 is shown in diagram 2062 in an L-network configuration with impedances Za and Zb. One or more of these two impedances can be implemented by means of an adjustable capacitor or inductor with the remaining impedances, if any, being implemented by means of fixed impedance, such as a fixed capacitor or inductor. Although three possible network configurations are shown, more complex impedance matching circuits can also be implemented with a greater number of impedances.
[0303] Now moving on to Figures 20H and 201, schematic diagrams 2064 and 2066 of non-limiting modalities are shown as an example of an adjustable impedance Za, Zb and / or Zc, according to several aspects described here. In particular, diagram 2064 presents a
Petition 870190094101, of 9/19/2019, p. 175/263
169/206 adjustable capacitor and the 2066 diagram shows an adjustable inductor. In various embodiments, the adjustable capacitor or adjustable inductor can be implemented by means of a plurality of fixed capacitors or inductors that are coupled together via a controllable switching network that responds to a 2056 control signal. For example, the signal Control Panel 2056 controls the switching network to couple those selected from these fixed capacitors or inductors together in a series or parallel circuit configuration to yield a desired total capacitance or inductance.
[0304] Now moving on to Figure 20J, a 2068 block diagram of a non-limiting example of an impedance adaptation circuit according to various aspects described here. In particular, the impedance matching circuit 2044 is shown to be implemented by means of an adjustable impedance matching transformer. For example, the adjustable impedance matching transformer can be implemented with a fixed transformer and one or more controllable current sources that respond to the 2056 control signals to adjust the transformer offset to control the impedance matching.
[0305] Moving now to Figure 20K, it illustrates a 2080 flow diagram of a non-limiting example of a method according to several aspects described here. In particular, a method for use with any of the functions and features previously described here is presented. Step 2082 includes receiving a
Petition 870190094101, of 9/19/2019, p. 176/263
170/206 radio frequency (RF) input to an impedance adaptation circuit from a transmitter. Step 2084 includes generating, through the impedance adaptation circuit, an output RF signal in response to the input RF signal. Step 2086 includes generating, in response to the output RF signal and by means of a guided wave launcher, an electromagnetic wave guided along a surface of a transmission medium, in which the electromagnetic wave propagates along the surface of the transmission medium without requiring an electrical return path, and where the transmission medium is opaque to optical signals. Step 2088 includes generating a mismatch signal based on the output RF signal, where the mismatch signal indicates an impedance mismatch of the guided wave launcher. Step 2090 includes generating one or more control signals in response to the mismatch signal. Step 2092 includes adjusting, in response to one or more control signals, one or more adjustable circuit elements of the impedance matching circuit, where the adjustment facilitates the reduction of the impedance mismatch of the guided wave launcher to compensate for changes impedance of the guided wave launcher that result from the change in climatic conditions in an area of the transmission medium.
[0306] In various embodiments, the impedance adaptation circuit is configured as a Pi network, an L network or a T network and the one or more adjustable circuit elements may include an adjustable capacitor, an adjustable inductor and / or a transformer tunable. The one or more adjustable circuit elements may include a plurality of adjustable circuit elements, wherein the one or more signals
Petition 870190094101, of 9/19/2019, p. 177/263
171/206 control devices include a plurality of control signals and each of the plurality of control signals controls a corresponding of the plurality of adjustable circuit elements.
[0307] Although, for the sake of simplicity of explanation, the respective processes are shown and described as a series of blocks in Figure 20K, it must be understood and recognized that the claimed matter under discussion is not limited by the order of the blocks, since some blocks can occur in different orders and / or simultaneously with other blocks in relation to what is represented and described here. In addition, not all illustrated blocks may be required to implement the methods described here.
[0308] Turning now to Figures 21A and 21B, block diagrams are shown illustrating non-limiting example modalities of a 2100 waveguide system for launching hybrid waves in accordance with various aspects described here. The waveguide system 2100 may comprise probes 2102 coupled to a sliding or rotating mechanism 2104 that allows probes 2102 to be placed in different positions or orientations relative to an outer surface of an insulated conductor 2108. Mechanism 2104 may comprise a coaxial supply 2106 or other couplings that allow the transmission of electromagnetic waves by probes 2102. Coaxial supply 2106 can be placed in one position on mechanism 2104 so that the path difference between probes 2102 is half a wavelength or some multiple multiple
Petition 870190094101, of 9/19/2019, p. 178/263
172/206 odd of the same. When probes 2102 generate opposite phase electromagnetic signals, electromagnetic waves can be induced on the outer surface of isolated conductor 2108 which has a hybrid mode (such as an HEn mode).
[0309] Mechanism 2104 can also be coupled to a motor or other actuators (not shown) to move probes 2102 to a desirable position. In one embodiment, for example, the 2100 waveguide system may comprise a controller that directs the engine to rotate probes 2102 (assuming they are rotating) to a different position (for example, east and west) to generate waves devices that have a horizontally polarized HEn mode as shown in a 2200 block diagram of Figure 22. To guide electromagnetic waves to the outer surface of insulated conductor 2108, the 2100 waveguide system may further comprise a tapered horn 2110 shown in Figure 21B. The funnel horn 2110 can be coaxially aligned with the insulated conductor 2108. To reduce the cross-sectional dimension of the funnel horn 2110, an additional insulation layer (not shown) can be placed on the insulated conductor 2108. The additional insulation layer can be similar to the tapered insulation layer 1879 shown in Figures 18Q and 18R. The additional insulation layer may have a tapered end that faces away from the tapered horn 2110. The tapered insulation layer 1879 can reduce an initial electromagnetic wave size launched in accordance with a HE11 mode. As the electromagnetic waves propagate towards
Petition 870190094101, of 9/19/2019, p. 179/263
173/206 to the tapered end of the insulation layer, the HEn mode expands until it reaches its full size, as shown in Figure 22. In other embodiments, the 2100 waveguide system may not need to use the tapered insulation layer 1879 .
[0310] Figure 22 illustrates that HEn mode waves can be used to mitigate obstructions, such as rainwater. For example, suppose that rainwater caused a film of water to surround an outer surface of insulated conductor 2108 as shown in Figure 22. Let us further assume that water droplets have accumulated on the bottom of insulated conductor 2108. As illustrated in Figure 22, the water film occupies a small fraction of the total HEn wave. Also, having horizontally polarized HEn waves, the water droplets are in a less intense area of the HEii waves, thus reducing losses caused by the droplets. Consequently, HEn waves experience much smaller propagation losses than Goubau waves or waves that have a mode that is firmly coupled to the isolated conductor 2108 and, thus, greater energy in areas occupied by water.
[0311] It is submitted that the waveguide system 2100 of Figures 21A and 21B can be replaced by other waveguide systems of the disclosure under discussion capable of generating electromagnetic waves having an HE mode. For example, the waveguide system 18 65 'of Figure 18W can be configured to generate electromagnetic waves having an HE mode. In one embodiment, two or more MMIC 1870 of the 1865 'waveguide system can be configured to generate waves
Petition 870190094101, of 9/19/2019, p. 180/263
174/206 electromagnetic opposites in order to generate polarized e-fields, such as those present in an HE mode. In another modality, different pairs of MMIC 1870 can be selected to generate HE waves that are polarized in different spatial positions (for example, north and south, west and east, northwest and southeast, northeast and southeast, or other subfraction coordinates). In addition, the waveguide systems of Figures 18N to 18W can be configured to launch electromagnetic waves that have a HE mode in the core 18 52 of one or more modalities of the 1850 cable suitable for the propagation of HE mode waves.
[0312] Although HE waves may have desirable characteristics for mitigating obstructions in a transmission medium, it is assumed that certain wave modes that have a cutoff frequency (for example, TE modes, TM modes, TEM modes or combinations of them) may also exhibit waves that are large enough and have polarized e-fields that are orthogonal (or approximately orthogonal) in relation to a region of an obstruction allowing its use to mitigate the propagation losses caused by the obstruction. The 2070 method can be adapted, for example, to generate such wave modes from a lookup table in step 208 6. Wave modes that have a cutoff frequency that exhibits, for example, a wave mode greater than the obstruction and polarized e-fields perpendicular (or approximately perpendicular) to the obstruction can be determined through experimentation and / or simulation. Since a combination of parameters (for example, magnitude, phase, frequency, wave mode (or modes), positioning

175/206 spatial, etc.) to generate one or more waves with cutoff frequencies that have low propagation loss properties is determined, the parametric results for each wave can be stored in a lookup table in a system memory. waveguide. Similarly, wave modes with cut-off frequencies that exhibit properties that reduce propagation losses can also be generated iteratively using any of the search algorithms previously described in the process from steps 2082 to 2084.
[0313] In relation now to Figure 23, a block diagram of a computing environment is illustrated according to several aspects described here. To provide additional context for various modalities within the modalities described in this document, Figure 23 and the following discussion are intended to provide a brief overview of a suitable 2300 computing environment in which the various disclosure modalities under discussion can be implemented. Although the modalities have been described above in the general context of computer executable instructions that can be executed on one or more computers, those skilled in the art will recognize that the modalities can also be implemented in conjunction with other program modules and / or as a combination of hardware and software.
[0314] Program modules generally comprise routines, programs, components, data structures, etc., that perform particular tasks or implement particular abstract data types. Furthermore, experts in

It should be noted that any functions and features described here in connection with the operation of a processor can also be performed by a processing circuit.
[0316] The terms first, second, third and so on, as used in the claims, unless clarified otherwise in the context, are intended for clarity only and do not indicate or otherwise imply any order in time. For example, a first determination, a second determination and a third determination do not indicate or imply that the first determination must be made before the second determination, or vice versa, etc.
[0317] The illustrated modalities of the modalities here can also be practiced in computing environments

In this regard, tangible or non-transitory terms in this document as applied to storage, memory or computer-readable media must be understood as excluding only transitory signs that propagate by themselves as modifiers and not renouncing everyone's rights. means of storage, memory or computer readable that are not just transitory signals that propagate by themselves.
[0320] Computer-readable storage media can be accessed by one or more local or remote computing devices, for example, via access requests, queries or other data recovery protocols, for a variety of operations with respect to information stored in the medium.
[0321] The media typically incorporates computer-readable instructions, data structures, program modules or other structured or unstructured data into a data signal, such as a modulated data signal, for example, a wave carrier or other transport mechanism, and comprise any means of delivering or transporting information.

For the 2302 computer, the drives and storage media accommodate the storage of any data in a suitable digital format. Although the description of computer-readable storage media above refers to a hard disk drive (HDD), a removable magnetic floppy disk and removable optical media, such as a CD or DVD, should be recognized by those skilled in the art. other types of storage media that are readable by a computer, such as, for example, zip drives (zip drives), magnetic cassettes, flash memory cards, cartridges and the like, can also be used in the example operating environment and, moreover, that any of these storage media may contain instructions executable by computer to carry out the methods described herein.

185/206 [0333] 0 Wi-Fi can connect to the Internet from a sofa in a residence, a bed in a hotel room or a conference room at work, wirelessly. Wi-Fi is a wireless technology similar to that used in a cell phone that allows these devices, for example, computers, to send and receive data indoors and outdoors; anywhere within the range of a base station. Wi-Fi networks use radio technologies called IEEE 802.11 (a, b, g, n, ac, ag, etc.) to provide secure, reliable and fast wireless connectivity. A Wi-Fi network can be used to connect computers to each other, to the Internet and to wired networks (which can use IEEE 802.3 or Ethernet). Wi-Fi networks operate on unlicensed 2.4 and 5 GHz radio bands, for example, or with products that contain both bands (dual band), so that networks can provide real performance similar to Ethernet networks basic lOBaseT cables used in many offices.
[0334] Figure 24 presents an example 2400 model of a 2410 mobile network platform that can implement and explore one or more aspects of the disclosed discussion matter described in this document. In one or more embodiments, the mobile network platform 2410 can generate and receive signals transmitted and received by base stations (for example, base station devices 1504, macrocell location 1502 or base stations 1614), central office (for example, example, central office 1501 or 1611) or transmission device 101 or 102 associated with the matter under discussion. Generally, the 2410 wireless network platform can comprise components, for example,
Petition 870190094101, of 9/19/2019, p. 192/263
186/206 nodes, gateway, interfaces, servers or disparate platforms that facilitate packet switching (PS) traffic (for example, internet protocol (IP), Frame Retransmission, asynchronous transfer mode (ATM)) and circuit switching (CS) (for example, voice and data), as well as generation of control for wireless network telecommunication. As a non-limiting example, the 2410 wireless network platform can be included in telecommunications carrier networks, and can be considered carrier-side components as discussed elsewhere in this document. The mobile network platform 2410 comprises gateway node (s) CS 2422 which can interact with CS traffic received from legacy networks such as 2440 telephone network (s) (e.g. public switched telephone network (RPTC) or public terrestrial mobile network (PLMN) or a signaling system network 7 (SS7) 2470. The circuit switching gateway node (s) 2422 can authorize and authenticate traffic (e.g. voice) arising from these networks.In addition, the gateway node (s) CS 2422 can access mobility data, or roaming, generated by the SS7 2470 network, for example, mobility data stored in a registry visitor location (VLR), which can reside in memory 2430. In addition, the gateway node (s) CS 2422 interacts with traffic and signaling based on CS and node (s) PS 2418 gateway. As an example, on a 3GPP UMTS network, the CS 2422 gateway node (s) can be perceived at least in part to the gateway GPRS support node (s) (GGSN). It must be recognized that the functionality and
Petition 870190094101, of 9/19/2019, p. 193/263
187/206 the specific operation of the CS 2422 gateway node (s), PS 2418 gateway node (s) and 2416 service node (s) are provided and dictated by radio technology (s) used by the 2410 mobile network platform for telecommunication.
[0335] In addition to receiving and processing CS switching traffic and signaling, the PS 2418 gateway node (s) can authorize and authenticate PS-based data sessions with served mobile devices. Data sessions may comprise traffic, or content (s), exchanged with networks external to the 2410 wireless network platform, such as 2450 wide area network (s), 2470 corporate network (s) and network (s) 2480 service providers that can be incorporated into a local area network (LAN), and can also interact with the 2410 mobile network platform through the PS 2418 gateway node (s). It should be noted that 2450 WAN and 2460 corporate network (s) can incorporate, at least in part, one or more service networks as an IP multimedia subsystem (IMS). Based on the radio technology layer (s) available on 2417 technology resource (s), the 2418 packet switching gateway node (s) can generate contexts packet data protocol when a data session is established; other data structures can also be generated that facilitate the routing of data in packets. To that end, in one aspect, the PS 2418 gateway node (s) may comprise a tunnel interface (e.g., network termination tunnel (TTG) gateway (s) 3GPP UMTS (not shown)) that can

188/206 facilitate communication in packets with disparate wireless network (s), such as, for example, Wi-Fi networks.
[0336] In 2400 mode, a 2410 wireless network platform also comprises service node (s) 2416 which, based on the layer (s) of radio technology available in the resource (s) ) of technology 2417, conduct the various streams in packets of data streams received through the gateway node (s) PS 2418. It should be noted that for resource (s) of technology 2417 that depends (m) essentially of CS communication, the server node (s) can deliver traffic without dependence on the gateway node (s) PS 2418; for example, the server node (s) may at least partially incorporate a mobile switching center. As an example, on a 3GPP UMTS network, the 2416 server node (s) can be incorporated into the service GPRS support node (s) (SGSN).
[0337] For radio technologies that exploit packet communication, the 2414 server (s) on the 2410 wireless network platform can run numerous applications that can generate multiple streams or data streams in disparate packets and manage (for example, time, queue, format, ...) these flows. These application (s) may comprise supplementary features for standard services (for example, provisioning, billing, customer service, ...) provided by the 2410 wireless network platform. The data strings (for example , content (s) that are part of a voice call or data session) can be routed to the PS 2418 gateway node (s) for authorization / authentication and initiation of
Petition 870190094101, of 9/19/2019, p. 195/263
189/206 a data session, and up to service node (s) 2416 for communication thereafter. In addition to the application server, the 2414 server (s) can comprise a utility server (s), a utility server can comprise a provisioning server, an operations and maintenance server, a security that can implement at least in part a certification authority and firewalls, as well as other security mechanisms and the like. In one aspect, the security server (s) ensures communication served over the 2410 wireless network platform to ensure network data operation and integrity in addition to authorization and authentication procedures that gateway node (s) CS 2422 and the gateway node (s) PS 2418 can be put into practice. In addition, the provisioning server (s) may (s) provision services from external network (s) such as networks operated by a disparate service provider; for example, WAN 2450 or Global Positioning System (GPS) network (s) (not shown). The provisioning server (or servers) can also provision coverage over networks associated with the 2410 wireless network platform (for example, deployed and operated by the same service provider), such as the distributed antenna networks shown in Figures 1 (s ) that intensify wireless service coverage by providing more network coverage. Repeater devices, such as those shown in Figures 7, 8 and 9, also enhance network coverage in order to enhance the subscriber service experience through the UE 2475.
Petition 870190094101, of 9/19/2019, p. 196/263
190/206 [0338] It should be noted that the 2414 server (or servers) may comprise one or more processors configured to provide at least partially the 2410 macrorede platform functionality. To that end, one or more processors may execute instructions for code stored in memory 2430, for example. It should be recognized that the 2414 server (s) may comprise a 2415 content manager that operates in substantially the same manner as described earlier in this document.
[0339] In example mode 2400, memory 2430 can store information related to the operation of the 2410 wireless network platform. Other operational information may include provisioning information from mobile devices served over the 2410 wireless platform network, databases subscriber; application intelligence, pricing schemes, for example, promotional rates, flat rate programs, coupon campaigns; technical specification (or specifications) consistent with telecommunication protocols for operating layers of radio technology, or triggered wireless; and so on. The 2430 memory can also store information from at least one between 2440 telephony network (s), 2450 WAN, 2470 corporate network (s) or SS7 2460 network. In one aspect, the 2430 memory can be, for example, example, accessed as part of a data storage component or as a remotely connected memory store.

195/206 (north, south, west and east, as well as combined directions in degrees, minutes or other suitable orientation metric).
[0348] The communication device 2500 can use transceiver 2502 to also determine proximity to a cell phone, WiFi, Bluetooth® or other wireless access points by detecting techniques such as the use of a received signal strength indicator (RSSI) and / or arrival time (TOA) measurements of the signal or flight time (TOF).

Petition 870190094101, of 9/19/2019, p. 202/263
196/206 [0350] In the specification under discussion, terms such as, for example, storing, storing, storing data, storing data, database and substantially any other information storage component relevant to the operation and functionality of a component refer to memory components or entities embedded in memory or components comprising memory. It will be recognized that the memory components described herein may be volatile memory or non-volatile memory, or may comprise both volatile and non-volatile memory, as an illustration, and not limitation, volatile memory, non-volatile memory, disk storage and memory storage. In addition, non-volatile memory can be included in read-only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable ROM (EEPROM) or flash memory. Volatile memory can comprise random access memory (RAM) that acts as an external cache memory. As an illustration and not a limitation, RAM is available in many forms, such as synchronous RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), SDRAM improved (ESDRAM), DRAM Synchlink (SLDRAM) and RAM RAM direct (DRRAM). In addition, the memory components disclosed of systems or methods herein are intended to comprise, without limitation, these and any other suitable types of memory.
[0351] Furthermore, it will be noted that the matter under discussion may be practiced with other computer system configurations comprising
Petition 870190094101, of 9/19/2019, p. 203/263
197/206 single-processor or multi-processor computer systems, minicomputing devices, mainframe computers, as well as personal computers, portable computing devices (eg PDA, phone, smartphone, watch, tablets, netbooks, etc.), industrial or consumer electronics programmable or microprocessor-based, and the like. The illustrated aspects can also be practiced in distributed computing environments where the tasks are performed by remote processing devices that are connected through a communications network; however, some, if not all, aspects of the disclosure under discussion can be practiced on standalone computers. In a distributed computing environment, program modules can be located on both local and remote memory storage devices.
[0352] Some of the modalities described here may also employ artificial intelligence (AI) to facilitate the automation of one or more features described here. For example, artificial intelligence can be used on the optional training controller 230 to evaluate and select candidate frequencies, modulation schemes, MIMO modes and / or guided wave modes in order to maximize transfer efficiency. The modalities (for example, in connection with the automatic identification of acquired cell sites that provide maximum value / benefit after addition to an existing communication network) can employ various AI-based schemes to carry out various modalities From
Petition 870190094101, of 9/19/2019, p. 204/263
198/206 same. In addition, the classifier can be used to determine a classification or location priority for each cell in the acquired network. A classifier is a function that maps an input attribute vector, x = (xl, x2, x3, x4, ..., xn), with a confidence that the input belongs to a class, that is, f (x ) = confidence (class). This classification can employ an analysis with a probabilistic and / or statistical basis (for example, factoring in the utilities and costs of analysis) for the prognosis or inference of an action that a user wants to be automatically performed. A support vector machine (SVM) is an example of a classifier that can be employed.
SVM operates by finding a hypersurface in the space of possible entries, in which the hypersurface tries to divide the triggering criteria for non-triggering events. Intuitively, this makes the correct classification for testing data that is close to, but not identical to, training data. It is possible to employ other targeted and undirected model classification approaches comprising, for example, naive Bayes, Bayesian networks, decision trees, neural networks, fuzzy logic models and probabilistic classification models providing different patterns of independence. The classification as used here is also inclusive of statistical regression that is used to develop priority models.
[0353] As will be readily recognized, one or more of the modalities may employ classifiers that are explicitly trained (for example, via
Petition 870190094101, of 9/19/2019, p. 205/263
199/206 generic training), as well as implicitly trained (for example, by observing UE behavior, operator preferences, historical information, receiving extrinsic information). For example, SVM can be configured via a learning or training phase within a module for selecting particularities and classifiers / builders. In this way, the classifier (s) can be used to automatically learn and perform various functions, including, but not limited to, determination according to predetermined criteria whose acquired cell locations will benefit from a maximum number of subscribers and / or whose acquired cell sites will add a minimum value to the existing communication network coverage, etc.

As an example, a component can be, but is not limited to, a process running on a processor, a processor, an object, an executable, a thread of execution, instructions executable by a computer, a program and / or a computer. As an illustration and not a limitation, both an application running on a server and the server can be a component.

200/206 component can be located on a computer and / or distributed between two or more computers. In addition, these components can run from various computer-readable media having various data structures stored there. Components can communicate via local and / or remote processes, such as, for example, according to a signal having one or more data packets (for example, data from one component interacting with another component on a local, distributed system and / or over a network, such as the Internet with other systems via the signal). As another example, a component can be a device with specific functionality provided by mechanical parts operated by a set of electrical or electronic circuits that is operated by a software or firmware application run by a processor, where the processor can be internal or external relative to the device and runs at least part of the software or firmware application. As yet another example, a component can be a device that provides specific functionality through electronic components without mechanical parts, the electronic components can comprise a processor to run software or firmware that confers, at least in part, the functionality of the electronic components. Although several components have been illustrated as separate components, it will be recognized that multiple components can be implemented as a single component, or a single component can be implemented as multiple components, without departing from the example modalities.

205/206 [0362] In addition, a flowchart can include a start and / or continue indication. The start and continue indications reflect that the steps presented can optionally be incorporated into, or used in conjunction with, other routines. In this context, beginning indicates the beginning of the first stage presented and may be preceded by other activities not shown specifically. In addition, the indication continue reflects that the steps presented can be performed multiple times and / or can be followed by other activities not shown specifically. Furthermore, although a flow chart indicates a particular ordering of steps, other orderings are also possible as long as the principles of causality are maintained.
[0363] As may also be used in this document, the terms operably coupled to, coupled to and / or coupling include direct coupling between items and / or indirect coupling between items via one or more intervening items. These intervening items and items include, but are not limited to, junctions, communication paths, components, circuit elements, circuits, function blocks and / or devices. As an example of indirect coupling, a signal conducted from a first item to a second item can be modified by one or more intervening items by modifying the shape, nature or format of information in a signal, whereas one or more elements of the information in the signal are, however, conducted in a way that can be recognized by the second item. In another example of indirect coupling,

206/206 an action on the first item may cause a reaction on the second item as a result of actions and / or reactions on one or more intervening items.
[0364] Although specific modalities have been illustrated and described here, it should be recognized that any provision that achieves the same or similar purpose can be substituted for the modalities described or shown by the disclosure under discussion. The disclosure under discussion is intended to cover any and all adaptations or variations of various modalities. The combinations of the above modalities, and other modalities not specifically described here, can be used in the disclosure under discussion. For example, one or more features of one or more modalities can be combined with one or more features of one or more modalities. In one or more modalities, the particularities that are positively recited can also be negatively recited and excluded from the modality with or without replacement by another structural and / or functional particularity. The steps or functions described with respect to the disclosure modalities under discussion can be carried out in any order. The steps or functions described with respect to the disclosure modalities under discussion can be carried out alone or in conjunction with other stages or functions of the disclosure under discussion, as well as from other modalities or from other steps that were not described in the disclosure in discussion. In addition, more than, or less than, all the features described with respect to a modality can also be used.
