Abstract:
A range between a first wireless device and a second wireless device is estimated using a first mechanism based on messages transmitted over a first communication channel. The first communication channel is associated with a first radio access technology capability of the wireless devices. One or more metrics indicative of an accuracy of the range estimates provided by the first mechanism are obtained. A second mechanism to estimate a range between the first wireless device and the second wireless device may be implemented in favor of the first mechanism when the metric fails to satisfy a criterion. The second mechanism is based on unicast messages transmitted over a second communication channel. The second communication channel is associated with a second radio access technology capability of the wireless devices and may be the same as, or different from, the first communication channel.
Abstract:
Disclosed are methods, devices, systems, apparatus, servers, computer-/processor-readable media, and other implementations, including a method of estimating a range between a first wireless device and a second wireless device that includes obtaining, at the first wireless device, first information related to a first broadcast message transmitted by the first wireless device, and obtaining, at the first wireless device, second information related to a second broadcast message transmitted by the second wireless device, with the second broadcast message including at least some of the first information. The method also includes determining the range between the first wireless device and the second wireless device based, at least in part, on the first information and the second information.
