Abstract:
1. A system for measuring the quantity, type, transmission quality and visit data of a plurality of mobile communication devices within a venue, the system comprising: a plurality of sensor devices, each of the plurality of sensor devices comprising a processor, a persistent storage, and one or more radiofrequency radio receivers operating in the 2-6Ghz range; a data server comprising a processor, a database, at least one network connection, an application programming interface (API) and at least one computer program configured to receive data uploads and store the data uploads in the database; and a console application comprising a user interface and a charting function designed to create filtered charting data; wherein each of the plurality of sensor devices is configured to use one or more of the radiofrequency radio receivers to capture a plurality of WiFi protocol management transmissions from a plurality of mobile devices within range of a defined geographic area of the venue, wherein each of the plurality of sensor devices is configured to record to the persistent storage transmission data comprising each of the plurality of WiFi protocol management transmissions, and record for each of the WiFi protocol management transmissions a radio identifier for the mobile device, a transmission signal strength, and a transmission time; wherein each of the plurality of sensor devices periodically connects to the data server over a network and uploads the recorded WiFi protocol management transmissions to the data server; wherein the data server is configured to receive the recorded transmission data from each of the plurality of sensor devices and associate the recorded transmission data with a corresponding sensor device of the plurality of sensor devices; wherein the API of the data server is configured to grant access to one or more analysis and visualization tools running in the console application; wherein the console application is configured to display the venue visit data and quality information for a WiFi connection to an end-user operator; wherein the plurality of sensor devices positioned within the venue are utilized to determine a geographical location of a mobile communication device based on a statistical analysis of received signal strength at each of plurality of sensor devices using a statistical model of previously received signal strengths of overlapping coverage at the plurality of sensor devices composed of histograms recording the signal strengths of packets from a mobile device at a target location received by the plurality of sensor devices, and wherein the histograms are converted into probability distributions, wherein the probability distributions are converted into distribution vectors.
