Abstract:
According to an embodiment, a method of estimating a location of an access point is provided. The method includes storing a first and a second sample respectively received from a first and a second mobile device, both samples including a location of their respective mobile devices, an access point identifier from the access point, and a value corresponding to a signal strength of a signal from the access point measured at their respective mobile device. A first and second platform profile is selected based on characteristics of the respective first and second mobile devices. The cells of a matrix are populated with probabilities based on mobile device locations, the signal strength values and platform profiles based on platform profiles associated with mobile devices. Finally, the location of the access point is estimated based on the matrix.
