Abstract
A method for estimating a location of a target Wireless Local-Area Network (WLAN) device includes obtaining relative locations of three or more WLAN devices. Respective distances are measured between each of the WLAN devices and the target WLAN device. The location of the target WLAN device is estimated based on the locations of the WLAN devices and on the measured distances, wherein measuring a distance between a WLAN device and the target WLAN device includes: exchanging WLAN signals, detecting a first leakage signal by a receiver of the WLAN device, detecting a second leakage signal by the receiver of the target WLAN device, calculating time differences between a time a WLAN signal was sent and a time a leakage signal was detected, and subtracting the time differences one from the other to obtain a time-of-flight that corresponds to the distance between the WLAN device and the target WLAN device.
