Abstract
Disclosed are methods, systems and devices for obtaining a range between devices based, at least in part, on an exchange of wireless messages. For example, wireless devices may obtain measurements of range based, at least in part, on an exchange fine timing measurement (FTM) messages. In one implementation, a message transmitted from a first wireless transceiver device to a second wireless transceiver device may comprise one or more parameters indicative of a range between the first wireless transceiver device and the second wireless transceiver device, or a range between the first wireless transceiver device and a third wireless transceiver device other than the second wireless transceiver device.
