ABSTRACT:
A system and method for determining if a first and second device are co-located includes first and second sensors for receiving a sample signal. Each sensor is coupled to the first and second devices. The first and second devices each responsively generate a first and second signal representing the sampled signal. Also included is a transmission device located at the first device for transmitting the first signal to the second device and a receiving device located at the second device for receiving the first signal from the first device. Finally, a signal analysis device determines if the first and second devices are co-located.
