Abstract
Disclosed are processes, devices and systems for exchanging messages between devices in support of measuring ranges between devices. In one particular implementation, a first wireless transceiver device may transmit one or more fine timing measurement (FTM) messages to a second wireless transceiver device, and receive a message acknowledging receipt of at least one of the one or more FTM messages. The first wireless transceiver device may authenticate the received message as being transmitted from the second wireless transceiver device.
