Abstract:
In an embodiment, the present invention is a method for ranging which includes emitting an acoustic signal at a first frequency, monitoring for a first acoustic response signal at a second frequency, and responsive to receiving the first acoustic response signal within a predetermined amount of time, (1) calculating a first distance between a first device and a second device based on a duration between emitting the first acoustic signal and receiving the first acoustic response signal, and (2) broadcast a first message including the distance and an identifier.
