Abstract
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.
