Abstract:
Apparatuses and methods for performing multi-channel passive ranging operations are disclosed. In one example, a passive listening device may receive, on a first wireless channel, a first exchange of signals between a first wireless device and a second wireless device, and then receive on a second wireless channel, a second exchange of signals between the first wireless device and the second wireless device, the first wireless channel different than the second wireless channel. The passive listening device may determine a differential distance between the passive listening device and the first and second wireless devices based, at least in part, on the first and second exchanges of signals on the first and second wireless channels, respectively.
