Abstract:
In one embodiment, techniques are employed to estimate a position of a wireless local area network (WLAN) enabled mobile device. The mobile device receives one or more wireless local area network (WLAN) packets transmitted within a range of the mobile device. The mobile device extracts information from the one or more WLAN packets to identify one or more WLAN access points (APs), and caches information indicating an identity of the one or more WLAN APs and a time of detection of the one or more WLAN APs. Subsequent to the caching, a request may be received for a position estimate of the mobile device. In response to the subsequently-received request for the position estimate, the cached information is provided to a WLAN positioning system (WPS) to obtain an estimate of a position of the mobile device.
