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 subsequent FTM message transmitted in response to an FTM request message may comprise at least one field indicating a time of transmission of a previous FTM message and a time of receipt of an acknowledgement message transmitted in response to the previous FTM message.
