Abstract
Multiple smart meters periodically measure strengths of detected signals generated by fixed position wireless devices. A centrally located location determining system receives this data, and correlates received strengths of the signals generated by the specific fixed position wireless devices with the physical locations of the measuring smart meters. Periodically, updated signal strengths are received, and stored correlations are replaced with updated correlations. Strengths of signals generated by fixed position wireless devices are received from a mobile computing device, as measured by the mobile device. The location determining system compares the signal strengths received from the mobile computing device to the most current strengths of signals of the same fixed position wireless devices, as measured by multiple smart meters, so as to perform triangulation and determine the physical location of the mobile device.
