Patent ID: 8242960

Claim:
A method of using a Wireless Local Area Network (WLAN) and satellite enabled device to infer that a reference location associated with a detected WLAN access point (AP) is not the present location of the AP, the method comprising: identifying WLAN APs detected by the WLAN and satellite enabled device; accessing a reference database to obtain a reference location associated with at least one of the WLAN APs; receiving a plurality of possible Satellite Positioning System (SPS) location solutions of the device based on satellite measurements from at least three satellites; estimating a distance between the reference location associated with the WLAN AP and each of the plurality of possible SPS location solutions; and inferring that the reference location associated with the WLAN AP is not the present location of the WLAN AP if the distance between the reference location associated with the WLAN AP and a subset of the SPS location solutions is above a predetermined threshold.
