Abstract

A method and apparatus for location determination by a WLAN station is disclosed. The method can include a first WLAN station receiving a packet sent by a second WLAN station, deriving a channel quality metric for a channel between the first WLAN station and the second WLAN station, comparing the channel quality metric to a threshold, and calculating a distance between the first WLAN station and the second WLAN station in an instance in which the channel quality metric satisfies the threshold.
