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, an initial FTM request message may be transmitted from a first wireless transceiver device to a second wireless transceiver device comprising one or more parameters indicative of a request for transmission of FTM messages in a particular format.
