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 during sessions. In one implementation, an initiating wireless station may transmit an initial FTM request message to a responding wireless station wherein the initial FTM request message comprising one or more fields indicating a capability of the initiating STA to generate Range Reports.
