System and method of gathering WLAN packet samples to improve position estimates of WLAN positioning device
First Claim
1. A device for estimating the position of itself in response to gathering WLAN packets, said device comprising:
- a radio module for receiving at least one WLAN packet addressed to at least oneWLAN access point (AP), the radio module not receiving WLAN packets transmitted from the at least one WLAN AP while receiving the at least one WLAN packet addressed to the at least one WLAN AP, wherein the radio module omits transmission logic, thereby causing the device to be a receive-only device incapable of WLAN transmission;
extraction logic for extracting information from said at least one WLAN packet addressed to at least one WLAN access point (AP) not presently in range of the radio module to identify the at least one WLAN AP receiving the at least one WLAN packet; and
logic to cooperate with a WLAN-based positioning system to estimate the position of the device based at least in part on the information extracted from the at least one packet which identifies the at least one WLAN AP.

Abstract
Systems and methods of gathering WLAN packet samples to improve position estimates of WLAN positioning device. A device estimates the position of itself in response to gathering wireless signal information from WLAN access points (APs). The device includes a WLAN radio module for receiving WLAN signals transmitted by WLAN APs in range of said device, extraction logic for extracting information from said received WLAN signals to identify the WLAN APs, and logic to cooperate with a WLAN-based positioning system to estimate the position of the device based at least in part on the extracted information identifying the WLAN APs in the range of said device.
