Abstract
In one embodiment, techniques are employed to estimate a position of a wireless local area network (WLAN) enabled mobile device. The mobile device sniffs one or more WLAN packets destined for one or more WLAN devices other than the mobile device. Information identifying one or more WLAN APs is extracted from the one or more WLAN packets destined for the one or more WLAN devices other than the mobile device. A record of the one or more WLAN APs is generated that includes at least some of the extracted information. A WLAN positioning system (WPS) is cooperated with, to use the generated record of the one or more WLAN APs to obtain an estimate of a position of the mobile device.
Claims21
A method for estimating a position of a wireless local area network (WLAN) enabled mobile device, comprising:
- sniffing, by the mobile device, one or more WLAN packets destined for one or more WLAN devices other than the mobile device;
- extracting information identifying one or more WLAN access points (APs) from the one or more WLAN packets destined for the one or more WLAN devices other than the mobile device;
- generating a record of the one or more WLAN APs that includes at least some of the extracted information;
- and
- cooperating with a WLAN positioning system (WPS) to use the generated record of the one or more WLAN APs to obtain an estimate of a position of the mobile device.
A wireless local area network (WLAN) enabled mobile device operable to estimate a position, comprising:
- a WLAN radio module configured to sniff one or more WLAN packets destined for one or more WLAN devices other than the mobile device;
- extraction logic configured to
- extract information identify one or more WLAN access points (APs) from the one or more WLAN packets destined for the one or more WLAN devices other than the mobile device, and to
- generate a record of the one or more WLAN APs that includes at least some of the extracted information;
- and
- logic configured to cooperate with a WLAN positioning system (WPS) to use the generated record of the one or more APs to obtain an estimate of a position of the mobile device.
One or more non-transitory computer-readable media storing positioning software, the positioning software when executed operable to:
- cause a wireless local area network (WLAN) enabled mobile device to sniff one or more WLAN packets destined for one or more WLAN devices other than the mobile device;
- cause the mobile device to extract information identify one or more WLAN access points (APs) from the one or more WLAN packets destined for the one or more WLAN APs;
- cause the mobile device to generate a record of the one or more WLAN APs that includes at least some of the extracted information;
- and
- cooperate with a WLAN positioning system (WPS) to use the generated record of the one or more APs to obtain an estimate of a position of the mobile device.
