  • Patent number: 11202172
    Abstract: Disclosed is a system for managing indoor positioning data of a site having a plurality of zones. The system comprises a plurality of sensors, forming at least one sensor network, operable to collect positioning data of the at least one communication device visiting the site and the plurality of sensors. The at least one sensor network comprises an exit point for forwarding the collected positioning data based on at least a pre-determined time and a status of the least one communication device. The system also comprises a processing unit having a positioning module for determining spatial position of the at least one communication device, a site-map module for calibrating installation positions for the plurality of sensors, a network configuration module for configuring the at least one sensor network to collect and forward the positioning data, and an analytics module for determining aggregated analytics data based on the determined spatial position.

  • Patent number: 9578617
    Abstract: A system for measuring in an anonymous manner one or more spatial positions of one or more user devices within a region, wherein the system includes a wireless arrangement for receiving signals from the one or more user devices for determining the one or more spatial positions of the one or more user devices, wherein the wireless arrangement is operable to receive one or more user identification codes from the one or more user devices, wherein the one or more user identification codes include N bits; the system is operable to apply a mapping function to map the one or more user identification codes to form one or more corresponding secondary identification codes by decreasing an entropy of the one or more user identification codes by K bits; and the system is operable to modify the one or more corresponding secondary identification codes by increasing entropy of the one or more corresponding secondary identification codes by M bits.

  • Publication number: 20160171547
    Abstract: Disclosed are system and method for providing targeted advertising within a retail premises having a plurality of zones, each of the plurality of zones is associated with a retail context. The system and method comprise identifying spatial positions of portable communication devices associated with consumers in the retail premises and determining paths traversed by the portable communication devices within the retail premises by identifying sequences in which zones are visited by the portable communication devices. The identification of sequences is based on the spatial positions and dwell-time of the portable communication devices. The paths include retail contexts of the zones visited by the portable communication devices. Further, the system and method comprise selecting advertisement to be displayed, via at least one of a plurality of digital signages arranged in the retail premises, based on change in counter of the retail contexts of the paths.

  • Patent number: 9167554
    Abstract: The present disclosure provides a method and system for tracking one or more portable communication devices in a radio communication network in a facility. The system comprises two or more sensors and a server. Each of the two or more sensors is configured to record a radio signal strength corresponding to each of one or more radio signal probes from each of the one or more portable communication devices, by utilizing a corresponding media access control address of each of the one or more portable communication devices. The server is configured to determine a location coordinate of each of the one or more portable communication devices using the recorded radio signal strengths and an adaptive supervised machine learning system. A learning cycle of the adaptive supervised machine learning system is configured to initiate when a variation in one or more technical attributes of the radio communication network in the facility is detected.

  • Patent number: 9063208
    Abstract: A method and a system for accurately positioning an electronic device located in an indoor area, generates a request signal for determining the indoor location of the device, and sends the signal to a server coupled to the device through a network. The request signal contains certain parameters pertaining thereto, including the signal strength, and the information of the cell towers through which the device sent the signal. The server uses the signal parameters to determine information pertaining to an approximate spatial position of the device, and sends and information to the device. Multiple positioning algorithms are embedded in the computing hardware of the device, and the device executes these algorithms to determine the exact indoor location thereof.
