Abstract
A location-tracking system that includes multiple detector units that are deployed in a region of interest. The detector units receive uplink signals from wireless terminals that are active in the region, and measure the strengths of the received uplink signals. The system computes the locations of the terminals based on the measured signal strengths and the known locations of the detector units. The location-tracking system receives and analyzes downlink signals from one or more of the base stations of the wireless network. The detector unit uses the downlink signal to recover and synchronize to the timing of the wireless network's air-interface. Based on the extracted uplink allocations, and having synchronized with the air-interface, the system is able to distinguish between the uplink signal components originating from each terminal, and thus compute the location of each terminal.
