Abstract
The wireless communications system includes a plurality of wireless communications devices, with each device type having a known latency profile associated therewith. A wireless device detector includes a controller for cooperating with a transceiver for transmitting a plurality of device finding signals to a target wireless communications device. The target wireless communications device transmits a respective reply signal for each of the device finding signals. Also, the controller generates an observed latency profile for the target wireless communications device based upon the transmission of device finding signals and the received reply signals therefor, determines a propagation delay based upon the observed latency profile and the known latency profile, and estimates a range to the target wireless communications device based upon the determined propagation delay.
