Abstract:
1. A computer-implemented method for determining a wireless access point location, the method comprising: receiving, by one or more computing devices, session data from at least one mobile device, wherein each instance of the received session data includes one or more global positioning system (GPS) data points, one or more sensor data points, and one or more WiFi scan data points, wherein the one or more WiFi scan data points are associated with one or more wireless access points (WAPs); and calculating, by the one or more computing devices, a location of at least one of the one or more WAPs using at least a portion from each of the received one or more global positioning system (GPS) data points, the one or more sensor data points, and the one or more WiFi scan data points; wherein the location of the at least one of the one or more WAPs is calculated based at least in part by calculating a path for each instance of session data in a selected subset of session data, determining which instances of the selected subset of session data have an error greater than a predetermined error threshold based on a distance between the calculated paths for each instance of session data, and filtering out from the selected subset of session data those instances of the selected subset of session data for which the determined error is greater than the predetermined error threshold.
