Abstract
A system to determine a location of a signal emitting device is provided. First, second, and third data is received from at least one movable communication device. Each of the first, second, and third data include a unique identifier of the signal emitting device, a signal strength of a signal received by the at least one movable communication device from the signal emitting device, and a location of the at least one movable communication device when it received the signal. Each of the first, second, and third data include different locations of the at least one movable communication device. A location of the signal emitting device is computed based at least in part on the received first, second, and third data.
