SYSTEM AND METHOD FOR DETERMINING SIGNAL SOURCE LOCATION IN WIRELESS LOCAL AREA NETWORK

摘要

A system and method locates a wireless local area network (WLAN) signal source. A wireless LAN signal as an RF signal is propagated from a WLAN signal source at a fixed, known location to a plurality of receivers having unsynchronized clocks. The time-of-arrival is measured at each receiver and the timing relationship from the fixed, known location of the signal source is used to relate time-of-arrival measurements from a signal arriving from an unknown location.
