Patent ID: 8284103

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 a present location of the WLAN AP, the method comprising: identifying a plurality of WLAN APs detected by the WLAN and satellite enabled device; accessing a reference database to obtain a reference location associated with each WLAN AP of the plurality; receiving satellite measurements from at least two satellites; receiving a hybrid position estimate for the device, the hybrid position estimate being based on the satellite measurements and at least one of the reference locations associated with at least one of the WLAN APs of the plurality; estimating a distance between the reference location associated with at least one of the WLAN APs of the plurality and the hybrid position estimate of the device; and inferring that the reference location associated with the WLAN AP for which the distance was estimated is not the present location of the WLAN AP based on the distance between the reference location associated with the WLAN AP for which the distance was estimated and the hybrid position estimate of the device.
