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.
