A method and apparatus for determining a location of a wireless device within an environment. A wireless device, which is operable in a wireless communication system, comprises a transmitter for transmitting a first signal to a transponder, where the transponder operates independent of the wireless communication system. The wireless device further includes a receiver for receiving a second signal from the transponder, where the second signal includes identifying data associated with the transponder. The wireless device further includes a processor for determining a location of the wireless device within the environment or classifying the environment based at least in part upon the received identifying data.
L'invention concerne un procédé et un appareil permettant de déterminer la localisation d'un dispositif sans fil dans un environnement. Un dispositif sans fil, fonctionnant dans un système de communications sans fil, comprend un émetteur permettant d'émettre un premier signal vers un transpondeur, ledit transpondeur fonctionnant indépendamment du système de communications sans fil. Le dispositif sans fil comprend également un récepteur destiné à recevoir un second signal provenant du transpondeur, ce second signal incluant des données d'identification associées audit transpondeur. Le dispositif sans fil comprend enfin un processeur permettant de déterminer la localisation d'un dispositif sans fil dans l'environnement ou de classer l'environnement en fonction d'au moins une partie des données d'identification reçues.
