    METHOD OF TRACKING, MONITORING TRACKING SYSTEM AND TRACKER The present invention relates to a method of tracking devices, in particular displaceable devices, a tracking monitoring system and a tracker or tracking devise.
    Now tracking devices and systems are commonly know per se. Many of these know systems are GPS based, meaning thal they may not always be operable within buildings. While this circumstance does not necessarily hamper many public applications, it yet at least commercially is regarded a disadvantage when it comes © finding objects that are generally stored more or less deep within buildings where GPS may not be contacted. Other tracking systems are also known amongst which systems using telephone masts. Other, somewhat less widely known systems utilise the so-called long range radio transmitter system (LoRa). The LoRa system is maintained by a communications provider, e.g. a national telephone and communications company or institute and in practice forms a so called Wide Area Network (WAN). Very often if not mostly provided as a so-called open network service to the public, but it may equally be set up as a closed network, While the bandwidth offered by LoraWan is very low compared to intemet, it may communicate relatively easily with wireless devices, the range per radio mast may extend up to fifteen kilometres and the power consumption of the involved tracker may be relatively low. This information may also be taken from public articles such as "Wat is Lora gigenlijk”, a.o. published at https Awww computable nlfartikelfopinie/maobility/5776778/1500028wat-is-lora- gigenfijlchtml, on June 13, 2018. The article mentions various potential applications amongst which tracing a bicycle. Specific information as to the nature of the LoRa network may e.g. be taken from the leaflet "Lora van KPN - Connectiviteit voor Internet of Things", a.0. published at hitps//decplayernl/27 14987 3-Lora-van-kpn-connecliviteit- voor-internet-of-things.hitml, it is known that also with the LoraWan so-called geolocation may be performed, e.g. from the business web-site hips//zakelijdorim. kpn.comflora-forum-16fora- geolocation-8855/index3.himl, where the latest. The LoRa communications provider,
    by way of Rick §,, 7 months ago from 10 sept. 2018 advises fo utilise geolocation only for outdoor applications, incidentally, the provider further explains that accuracy for gealocating static objects is 60 meters.
    The present invention sets oul to yet satisfacionly provide a solution to this apparently widely felt, yet commercially most relevant problem of indoor tracking of objscls, in particular in an economic yet reliable manner. The invention also has for an object to securs that power consumption remains low and that the tracking device, La. it's power source, as used in such system, still remains sufficiently long lasting for commercial application. Yet goals of the present invention are to have the costs of the device relatively low despite the above desired high traceability quality, and to have the tracking device fitting a minimalistic envelope, so as to secure widespread use of such a device, Le. to enable application thereof also info smaller devices to be tracked such as small screwing or drilling sguipment.
    One such the example of the relevancy of indoor tracking of objects is provided by the business case of so called stack-carts (Dutch: "stapslwagen”), and the so denoted flower cart (Duich Bloemenkar), These are the most used means for transport of plants and flowers back and forth from greenhouse to trading centre and with the often vastly stretching indoor areas of flower trade centres.
    The cart as apart for transport by lorry, also used for indoor transportation by hand or towed in series by small a small tractor, should outside the flower trading centre buildings be provided with a so called key plate, sliternalively denoted lock, The key plate is a rectangular boxed key mechanism serving to safeguard and identify the cert It is thereto provided with a barcode and an RFID tag. The coding of the tag consists of a series of 26 numbers. 1 is the responsibility of the entrepreneur to have sufficient key plates in stock at the various, most visited places, since an in fact borrowed cart can not leave the trading premises without such key atlached to the cart. Carl rental is hence in fact paid by rental of key plates from, directly or indirectly, the cart owners, A draw back of this known tracking system is the key plates may be handled carslessly, e.g. by fransporiers at retuming a cart st the trade promises, in a manner that the key plate can no longer be found, while R is not returned to the owner, and should hence still be paid for. The same holds for carts that are for shorter or longer time left al a 385 greenhouse for loading flowers io be traded, The relatively expensive Rey plate withcart may be left in a corner or become destroyed without the key being returned, and without any means of finding back such key plate. Hence the transporter entrepreneur may suffer endlessly ongoing costs while no functional profit may be gained.
    In a project which the Inventor denominated as “SmartLoc’, the name referring both io the lock and the location, a solution to the above problem has been devised which unlike presently known tracking systems, enables tracking of the lock in a versatile manner, both in the open and within buildings such as the greenhouses and trade centres, and even within separate chambers such as cooling cells. The lock or key plate, in fact the node included therein is thereto provided with an active tracking system, using a known per se LoRaWAN IoT {Internet of Things) solution as discussed above. Additionally the node is provided with a WIFI protocol] stack for assessing local WIFt and Will access points information. In accordance with a system and method utilising such node, location information is determined using either one or both of assessed WiFi and LoraWAN gateway information. in such active node system the use of a ballery is required. One solution in accordance with the invention fo enable long battery life while still utilising a relatively small battery package involves a measure not to have the system in continuous operation, but rather to configure the device so that itis in most of the time in a 20 called slesp or low power modus, For position determination vast numbers of solutions may be encountered. In the present solution however low energy useage is of such importance that a new, low energy solution has been developed.
    28 Examples of such existing solutions of position determining solutions include non-pre published WQ2010060854 and pre-published US20180081717, with the latter examplifying the use of LoRa communication in positioning applications. The concept of the latter disclosure is disclosed as to have a powered module in communication with a receiver. The module, provided with a GPS module, is to receive a location request data packet from the receiver and to provide a location response data packet to the receiver. A micro-controller of the module periodically tums on its data communication assembly into receive mode in order to listen to a signal that may be being transmitted from the receiver. If no siognal is present, the microcontroller returns to sleep in order to conserve power. This publication does not deal with the above explained indoor positioning problem. In that respect the international publication
    WO20198060954 teaches the use of a wireless electronic device, e.g. in the form of a tag, Le. the device forming a tracking device, to emit a scan message.
    Ons example provided is sending a Wi-Fi probe request.
    This emission of a scan message is tc search for nearby electronic devices supporting it's wireless communication protocol, § denominated so called listening agent devices, Such listening agent device may be formed by installing a listening agent software application on a Wi-Fi modem or WIFI router device.
    Listening agent devices may send a probe response to the tag or wireless slectronic device or tracker, indicating their listening capability by inserting a predetermined listening agent identifier in the form of a binary sequence into a vendor specific information element (VSIE) of the probe response.
    The present invention seeks to yet further simplify the location concept, while maintaining the desired features of indoor and outdoor funclionality, low power consumption and minimal envelope.
    The present invention thersin in fact proposes fo 18 utilize environmental power, at least proposes that the tracker device is smbodied a passive device, Le. al wake up merely acting as a receiver of environmental wireless signals, in fact collecting an instantaneous environmental wireless signal signature, and passing on the data thus collected to a central computer for establishing positional information from the data packet! sent out by the tracker device, The invention thus recognizes and implements that environmental signal data is often present in abundance, at least may be used as a basis for position determination.
    This circumstance offen even holds on board of ships, Espedially in the later case but also on board of other vehicles such as trucks, rather than dispatching the collected data via LoRa, the data may also be sent via mobile device such as a mobile phone having allowed the installation of an application, so called app for such purpose.
    Also, in the present invention Wi-Fi is not used for despatching messages, i.e. the data packsts received from or representing the surrounding broadcast.
    Wit may according to the present invention be used by way of a mesh network, the concept of which is known per se, as an alternative and-or addition to a Lora facility on the device for relaying the data packages to the central computer.
    Known device is intrusive of nature, i.e, it actively and purposely sends a probe to Wi devices Into it's environment and expects to receive information in response thersto. #t then uses the BSSID or MAC ID in order to engage or act in response.
    Often data, eg. scan history is then send over WIEL which is not desired according to the present & invention, e.g. for reason of a requirement to login to a WIFI device.
    In fact a log of the data received in time is then dispatched over WIFL The latter is not preferred since if requires permission or to be logged In. in the invention the tracking device by way of a probe merely listens to the brosdoast of WiFi stations and dispatches the resulls of the probe, thereby using the known per se BSSID or Binary station Identifier and RSS! received.
    Sending of custimised data packages may in the invention be accomplished using one of LoRa, narrow band IOT or a commercial carrier network, including a cellular network, such as those of KPN, Sigfox and LTE-M.
    A disadvantage of such latter may he that logging in is required.
    In principle no use is made of a WIFI gateway of which the BSSID and RSS! fingerprint is assessed.
    Also, it is recognised by the present invention that establishing a WiFi] connection over a WIFE! device does not allow a vast multitude of tracking devices to be monitored as further desired by the invention, e.g. for low cost, yet commercial inventory tracking with a masive amount of tracking devices.
    Much more nodes are required in the commercialiy operable, at least aimed and inverted system of tracking and also the distance over which these devices are to be tracked is much larger that allowed by a WIFI device, which typically is within domestic range.
    A tracking device according to the invention typically, by way of redundancy, at least as a means of maximising the transmission of data packages is hence equipped with more than one type of communicating technology.
    Yet, the system and method of invention by it's nature accomplishes very low power consumption.
    Should however a battery after some considerable period of time become depleted, the microcontroller is equipped with a battery monitoring system and warning system, for emitting a warning system sufficiently in advance, in practice e.g. two months before expected full depletion of the otherwise normally small battery to the system.
    in a wifi mesh the tracking device may be woken up and briefly contacts & closest WIFI beacon for a very brief connection, hence the system may use the wifi mesh as a replacement of LoRa.
    Yet, for despatching over wireles net, LoRa, or commercial providers such as SIGFOX may be used.
    Normally it uses a point in last instance one can make an own network.
    During probe taking, the tracking device may identify a beakon.
    In that case the beacon may become the primary point of relay.
    In the probing, the tracking device passively listens to other users of the radio spectrum, more specifically to gateways, Le access points, since these are stationary, The information collected at the probe is collected in a small database or record as if were and may be completed with any GPS information that might be simultaneously received during such wake up. in a container boat, likely there is a if one beakon or own wifi gateway is provided a wifi-sccess then, especially with the customised and limited data package, a tracker device may use an existing WIFI mesh to arrive at the one, allowed wifi acces point.
    A self learning character of the system of the invention holds that once a data package af an environmental scan or probe has been registered, it may be provided or corrected with location information, either manually through personal knowledge of the instantaneous location of the device at the time of data, with GES information received in conjunction with the same data pakage at a later stage, or with matching location information from a Google map and database of WIE] access points.
    The invention will now by way of example be explained in mors detail with reference to figures: FIGURE 1 is a schematic representation of locating system in accordance with the invention; FIGURE 2A and 2B respectively set forth a pholographic and schematic representation of a LoRa node LN and it's components; FIGURE 3A and 3B respectively set forth a schematic representation of LoraWAN gateway LGW and a photographic representation of a small additional LoRaWAN gateway; FIGURE 4 is an example of a mapped representation of LoRaWAN galeways in 38 a smart location network system in accordance with the present invention;

    FIGURE © is an example of a dala set relating to a WIFI scan as may be performed in accordance with the invention for the purpose of locating a Lora Node LN and it's coupled, to be located device:
    Figure 10 illustrates an extended and versatile embodiment of the inventedmethod and system of tracking.
    In accordance with representation in FIG 1, the design of the “SmariLos" solution, is made up of several components: - 8 low-power, Lora node LN; - LoRaWan a gateway LWG - an internet provider ITC, in this example KPN, - @ {Web} Server 8; - a client application, such as a Website WS and / or App.
    MA The LORA node LN will at certain predetermined times, for example every hour return from a slesp mode.
    For position determination, the node LN has a GPS module and / or a WIFI protocol stack, Through the wireless protocol stack, first the surroundings are scanned for active AP's, Le.
    Access Points.
    From this scan, the node selects thres strongest APs.
    The WIFI protocol stack is solely used for mapping of the WIFI environment, There is no data transfer via the wireless protocol stack.
    When present, the GPS module is consulted a maximum number of times per day, for example, consulted twice a day and is allowed a maximum amount of time, for example three minutes, fo determine a position.
    With such measures the energy consumption is restricted.
    The node will now transmit the data via Lora, Subsequently, the node will, via the LoRaWAN gateway, communicate this information to the network.
    The gateway will via the Internet and a suitable lot provider exchange the data, The data is thenprocessed in a central (database) server, for example in accordance with the table in FIG 9, Received Wi-Fi scans will be compared with Wi-Fi data from the database.
    From this comparison 8 position is determined.
    When actual GPS data would have been & recsived, such data will be leading for the position determination, Simultaneously, the corresponding WiFi scan data will be stored in the database.
    The system has thus been made self-learning.
    In this project of application if is slected to is restricted to use “The Things Network" as IoT service provider, if here concerns a fres/open network which, unlike paid commercial networks such as KPN networks, simply may be used without costs for an application of location determination according to the invention.
    By installing IcT Gateways at customers, the coverage and the capacity of the oT network will increase.
    In accordance with the representation in Figures ZA and 2B, the Lora node LN, shown in Fig. 28 with a configuration identification Config ID, and in popular sense also referred to as the tracking device, consist of a small, in fact central, preferably RISC based microcontroller MUC with a WIFI protocol stack, a GPS module GPS and of a LORA transceiver TRC.
    In favourable embodiment, the microcontroller is equipped with a Wi-Fi protocol stack and holds sufficient YO to couple a GPS module and a Lora transceiver.
    In the in Fig. 2B provided example the Lora transceiver TRU is adapted to the European standard Lora 868 Mhz, and embodied here as a standard processor, which is at least compatible with the Sx1278 standard, so that it is possible to exchange data via most of the EU loT providers, in other words is operable with the EU Lora channels at 868Mhz.
    A tracker for world wide application will be embodied with communication facilities at multiple frequencies.
    The central microcontroller in this example controls the Lora transceiver via 120 and is in accordance with preference also responsible for the Lora protocol, including the AES encryption.
    The SmariLoc Node LN, ie. the node LN according to the invention, for the latter uses the Arduino port of the LMIC framework (LoraWAN-in-C). The software that controls the LoraWan protocol is based on an open implementation of IBM.
    The GPS module is provided with a processor which has both a GPS, Glonass, and Galileo support.
    The GPS module is read via the serial port of the central processor.
    The various components are compactly constructed, which makes them relatively simple in many applications such incorporation in a so called lock plate (Dutch: slotplaat) for flowercarts, For the eventual functionality the node LN is according to the invention provided with appropriate programming code lines, i.e. software, as may be readily set forth and applied a person skilled in the art, in other words with software which is specifically tailored to the requirements of a desired embodiment of the various modules.
    In accordance with representation in, amongst others FIG 1 and FIG 3A, the LoRaWAN gateway LGW controls the data transfer to the Internet, Such gateways may include stations located on masts for nationwide covering net work, by a communications provider OP. Such stations may be supplemented with smaller, proprietary” stations, of which, by way of example, an embodiment is represented in FIG 3B. These are lightweight, can in principle bs applied for example with a suction cup on a window of a building. The scope of such smaller channels is usually less, typically up to about 8 km. in the embodiment of the present invention, use is made of the open and costless available "The Things Network”. In this network a large number of gateways are available with which the node Lora LN according to the invention might connect. The present invention preferably extensively uses the possibility adding self-owned gateways LGW to {he network, In accordance with the invention this possibility is used to install gateways at or close to own, proprietary or frequently visited or otherwise strategic locations. The sign of the Lora node LN to the gateway LGW may in this manner additionally be used to estimate the target position e.g. the lock plate n a global manner in cases that GPS might not be available, such as is offen the case within a building. Figure 4 could form an example of such an additional coverage, by means of "own", or at least additional installations of smal! Lora stations LGW. Such, also denoted as "small" gateways, ars relatively inexpensivly available in the order of around € 300, and may be connected to the internet via a network, UTP cable or a wireless WiFi connection. The Sman Loo tracking or localization method further departs fron a hybrid system, In which also the WIFI environment is used as a location feature. WIFI is however expressly not used for communication with the Internet and also there is no communicating with the wireless network, Rather, in the localization method according to the invention, a scan is made of the available Wi-Fi access points, of the strongest three of which the MAC address is stored together with the measure of the bond orsignal strength, in other words of the so called RSS! If necessary, the differences in bond strength are also used to identify different locations within a building.
    The GPE is in the method according to the invention consulted as little as possible.
    Where a valid GFS position is determined, the corresponding WIFI scan is stored in the server databass.
    With this, the system is self-learning and strategic locations within buildings are recorded in the database with associated Wi-Fi information.
    In the method according to the present invention, when needed, use is made of the available position determination within LoraWan, which is based on the known locations of the in fact fo be nominated “large” galeway stations, Because several stations may receive the signal from a node LN a rough position determination is possible on the basis thereof.
    Depending on the number of gateways LGW, regardless af whether these belong to the LoraWan or to the selhinstalied, say small stations that receive the node LN, a more accurate position determination within the method according to the invention has been enabled.
    The method according to the invention, and thus the Smartl.oc System, uses the RSS! information of the gateway stations to calculate a weighted average position if necessary.
    This ís in the setup of the SmartLoc method and the Smartloc system, the preferably last preferred method to opt for in determining position information.
    This position determination can in doing so, in the present method and by the system be classified as to be inaccurate for location dependent or customer-specific billing of a customer for the apparent holding of a with the node LN linked object such as, for example, a flower cart.
    This situation will generally be prevented by locating additional gateways at strategic locations at setting up a closed networld, Le. a network specific for SmanLoc. it is noted that more expensive versions of the Smariloc nodes LN may use a Bluetooth facility provided thereon.
    In a mode BLE for short-range communication a option is acknowledged to improve positioning, In doing so, use is made of the fact thal, well-known Bluetooth nodes with known ID and position may placed at predetermined locations, Le, locations of which the validity is known with certainty, . The SmsrtLoc, at least Lora node LN according to the invention further allows use of a so-called "Deep Sleep’ mode, so that the node LN, in accordance with the invention, consumes extremely little energy.
    Only a necessary wake-up timer and some RAM ofthe realtime counter (RTC) in the module is used. Doing so allows the node LN to return to i's run context, Le, to find the same when if wakes up, or to allow continuation as from the point where it was before falling or going "asleep".
    inthe method according to the invention, the communication through the LoRaWan is determined by the Lora standard, The payload that is sent, is however minimized and therefore customized for SmartLoc system: this may depend on the wishes of the customer or the application take several forms. For instance, a 12-byts version, of which § bytes of so-called Lat/lon and 4 bytes for the battery voltage, a 13-byte version, of which 8 bytes of LaV/Lon and 4 bytes for the battery voltage and 1 byte which indicates whether there was a GPS fix) a 50 bytes version with 5x 10 bytes (= 8 bytes WIFI MAC address + 4 bytes RSS). In this version incidentally, in conformance with a further possible embodiment, there is no possibility whatsoever towards GPS information. A fourth example relates to an embodiment having 43 bytes, including B bytes of LaVLon, 4 bytes battery voltage, 1 byte GPS status, and 3x 10 bytes of Wi-Fi information. A fifth embodiment is also 43 byles In accordance with version 4, but with redefined coding of battery voltage.
    The thus extracted information is in accordance with the invention, incorporated in a dedicated server §, in the form of a database, Al incorporation, inter alia, the received wireless information is matched with WiFi information marked as known in the database. Another aspect of the locating method according to the invention is that the data server is provided with a self-learning algorithm for locating and establishing of Wi-Fi access locations. With that, the algorithm contains logic which ensures that there is virtually no information stored double. it is also provided, that an entry in the database is marked in a manner allowing recognition of whether the Wi-Fi location entry has been obtained by the self-learning or by manual input into the system, The manually input locations are preferred here over a matched WIFI location, Yet, it appears in practice that a very high and commercially useful degree of reliability is obtained, This certainty is in accordance with a further slgboration of the method according to the invention increased even more through a further part of the algorithm that performs a maich with customer data known in the databases. This additional match is determined by comparing the position of the node with the customer's position. Af such, the nearest customer is determined, and subsequently whether the position thereof is within a predetermined meaningful distance.
    FIG. 5 is an example of an information page out of the SmartLoc Localisation System SL, such as has been made available to a flower transportation business, provisional customer number 52833, and of which by way of trial, three of the transport carts under the responsibility of the business are equipped with a lock plate LN according to the invention.
    The figure lustrates that the three carts on certain date and Hime were located at two diferent locations represented by name. if necessary, an additional LoRaWAN gateway is installed at or near the location of a regular customer to accommodate the "SmsriLoo" nodes that will be around there.
    These lock plates can be followed via a simple web interface, and there will be a daily assessment of where or with whom these lock plates are.
    If a lock-plate provided object such as a flower cart is in between fixed, is. known locations, a relatively coarse location assessment is provided if so desired, whether or not on a separate page, of objects that are ” ikely in transport”,
    In accordance with the representation in FIG. 8, the system provides, in vet another page, an overview of nodes signed in at a network that is in this case called "The Things Network”, in this example anumber of 10 nodes.
    At predetermined times, for example every hour, the SmartLoc node LN will attempt to transmit its data to the oT network.
    In the payload, that is to say, in the transmitted data, there is present, as for example represented in FIG 7, in succession, the GPS position, 3 WIFI MAC addresses and an indication of the battery voltage.
    Yat another page of the system according to the invention provides, as shown in FIG. 8, the locations of additionally issued "internet of things {oT} Gateway stations LGW, here in a number of seven.
    So as to increase the coverage of the existing network these are posted at places strategic to application by a customer.
    For the management of the foregoing, a server is arranged on a specific network, in this example the 'Lohman-solutions.com’ network, which comprises a database such as an SQL database, a Web site, a MQTT connector, for sxample Python, and a data processor module for executing analysis.
    The database maintains a number of tables, sach with multiple of specific information for each component of the SmartLoc system, such as as a customer table, a message table, a Smartloc nodes LN table, a Wifi Location Table, and a results table.
    The desired data may be retrieved from thedatabase with appropriate queries. The following query is an example of how it is determined how many loc-plates or nodes are present at a certain location for each customer
    SELECT timestamp, at customer, description, b.customer_id, couni(a.at_customer} FROM smariplate.resulls a, smerplate plates b, smarpliais.customers ¢ WHERE a.plate_id=sb.plate_id AND ccustomer_id=a.al customer AND timestamp = (select max(timestamp) FROM smariplate. results) AND a.at distance «800 GROUP BY b customer id, af_customer; The website uses, in a potential, here elected embodiment, a Windows 2012 Server with JIS. For displaying of a map with information use is made of an open source library, which in the present case is written In the JavaScript language, The website also uses the PHP language, which works at the "server side”, and is used to relrieve 18 results from the SQL database. Because the resulls ars retrieved af the serverside, database access by the client is not required. A database with such a design is hence not directly” on the Internet. The web site in the embodiment according to the invention requires that for users, inter alia authentication is present, for a robust application of the present Smartl.oc location system SL.
    The MOTT (Message Queuing Telemety Transpor) connector, a standardised machine to machine (MZM) data transfer protocol, provides the coupling or link with the The Things Network, Through a Python script, a call back is obtained through the MOTT framework with new data from the SmariLoc Nodes involved, With this Python 28 script, in the on_message handler, the data of a SmartLoc Nods may be stored in the database. The data processor is a csleulation module which is every day at one or more predetermined times, €.¢., at 23:00 hour, initiated by a sc-called Task Scheduler. From the received massages it is derived where SmartLoc Nodes are located. For this purpose, the following algorithm is used: - ls the GPS data recently -> GPS position leading -> Position 1 - Is there a WIFI scan -> compare with WIFI data in the database > Position 2 - Position of the host gateways -> Weighted position in dependence of the received signal strength of the SmariLoc nodes -> position 3
    In order of importance, and availability position 1, position 2 and position 3, respectively, will be used for determination of the SmartLoc node SL. This algorithm, and these positions, as previously discussed, may be extended with reference to a, for example at a location disposed Bluetooth element and the scanning thereof, in the particular case where both a first position and a Wifi Scan is available, the database will be tested to see if there is already a WIFI scan present for this position, 1 not, then position 1 with associated Wi-Fi scan is added to the database.
    Figure 10 ilustrates an extended and versatile embodiment of the invented method snd system of tracking and collecting position information Pl, using a Wi-Fi Mesh network known per se as an alternative and/or in addition to LoRa, the network comprising Beacons B and using a local access point LAP to connect to the internet of things ITC; Position information PI as collected in a local database LDB may apart from e.g. GPS info be attained from the google WiFi access point database. The Wifi mesh network is in one embodiment used if no LoRa is available. Through brief contact between WIFI beacons B the data packet may be handed over without burdening the mesh of beacons or i's capacity, until a local WIFI access point is reached which transfers the package fo the ITC. Buch local access point may be formed by a device positioned thereto at a certain convenient location, and provied with an app Tor franferring the package. For instance in a truck, a mobile phone associated with the truck, e.g. that of the driver, may form a local access point LAR, in that if has installed an app for dala package relay, hence has expressly provided permission to use i's connection with the infernst. It may be clear that by the nature of the WIFI mesh no such use is made of the WIFI devices that form a beacon in the mesh, In such mesh system and method, a closest WIFI beacon is briefly connected for relaying the data package. H it indicates to be occupied, loaded or unavailable, a second closest beacon js contacted, which in tum contacts further beacons B until a beacon forming a local access point is found.
    At the server §, a local database of locations is automatically developed by gach package this received via the ITC. If an environmental fingerprint is registered without a GPS signal being sent together with if, the location may be manually input to the database. Alternatively, using a self Isarning feature and program provided to the server, position information may be added at a later stage 1 the same scan data is 38 received in conjunction with a GPS system, which is sometimes not available.
    Alternatively a google database containing amongst others MAC adresses of WIFI gate ways is used to retrieve or else approximate a certain location by executing a matching operation using MAC adresses and signal strength.
    As a result position information Pi is eventually delivered to MA or WE, based on a self learning, at least filling database of locations.
