Abstract
A method, device and system are disclosed for geo-locating a device. In one embodiment, a first wireless transmitter/receiver pages a second wireless transmitter/receiver to establish a communication. A plurality of packets transmitted by the first wireless transmitter/receiver and transmitted by the second wireless transmitter/receiver are received by a wireless receiver. The reception time of packets transmitted by the first wireless transmitter/receiver and the second wireless transmitter/receiver is recorded. A time delay based at least in part on the recorded reception times of each packet is calculated, and a location of the second wireless device based on the calculated time delay is determined. A target location of the second wireless transmitter/receiver is determined based on a plurality of the determined locations of the second wireless transmitter/receiver.
