Abstract
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.
