CA 2649527

A secure localization method for wireless networks utilizes access point variable transmission power capability to transmit encoded localization signals at different power levels to a wireless device in the network. Based on the particular combination of encoded signals collected by the wireless device and reported back to a network controller, the location of the wireless device may be determined in conjunction with information contained in a location database.

Un système sûr de localisation pour réseau sans fil fait intervenir une variation de la capacité de puissance de transmission variable au point d'accès pour transmettre des signaux de localisation codés à différents niveaux de puissance vers un dispositif sans fil au sein d'un réseau. Il est ainsi possible, à partir de la combinaison particulière de signaux codés recueillis par le dispositif sans fil et répercutés vers un contrôleur de réseau, de déterminer l'emplacement de ce dispositif sans fil en corrélation avec les informations contenues dans la base de données de localisation.
