CA 2713103

Embodiments of the present invention disclose a secure localization infrastructure using transmitters that can transmit messages at multiple distinct power levels throughout a community of reference points. Transmitters send messages at different power levels in a manner that every location in the system corresponds to a unique set of messages. Received messages are reported back to the localization infrastructure, which then determines location by comparing the messages reported.

Les modes de réalisation de la présente invention portent sur une infrastructure de localisation sécurisée utilisant des émetteurs qui peuvent émettre des messages à de multiples niveaux de puissance distincts dans toute une communauté de points de référence. Les émetteurs envoient des messages à différents niveaux de puissance, de telle sorte que chaque localisation dans le système correspond à un ensemble unique de messages. Les messages reçus sont rapportés à nouveau vers l'infrastructure de localisation, qui détermine ensuite la localisation par comparaison des messages rapportés.
