Title (EN) SYSTEM AND METHOD FOR DETERMINING SIGNAL SOURCE LOCATION IN WIRELESS LOCAL AREA NETWORK
(FR) SYSTEME ET PROCEDE POUR DETERMINER L'EMPLACEMENT D'UNE SOURCE DE SIGNAL DANS DES RESEAUX LOCAUX SANS FIL
Abstract: front page image
(EN)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.
(FR)La présente invention concerne un système et un procédé situant une source de signal de réseaux locaux sans fil (WLAN). Un signal de LAN sans fil prenant la forme d'un signal RF est propagé d'une source de signal WLAN à un emplacement connu, fixe vers une pluralité de récepteurs ayant des horloges non synchronisées. L'heure d'arrivée est mesurée au niveau de chaque récepteur et la relation temporelle depuis l'emplacement connu, fixe de la source de signal est utilisée pour réaliser des mesures d'heure d'arrivée à partir d'un signal arrivant d'un emplacement inconnu.
