Abstract: Techniques for exchanging secure FTM messages are disclosed. An example of a wireless transceiver system for providing a secure Fine Timing Measurement (FTM) exchange includes a memory and a processor configured to obtain a initial-secure-token value and a secure-token-response value via an out-of-band signal, generate a FTM Request message including the initial-secure-token value, a transmitter to send the FTM Request message to a responding station, and a receiver to receive a FTM Response message including the secure-token-response value from the responding station, such that the at least one processor is configured to determine a Round Trip Time (RTT) value based at least in part on the FTM Response message.

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.

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.

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 initiating wireless station may transmit an initial FTM request message comprising one or more fields to a responding wireless station specifying an indefinite duration for a requested session to transmit FTM messages to the initiating wireless station.

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.

Abstract: Techniques for estimating a position of an observing station are disclosed based on capturing, at the observing station, a first and a second FTM message exchanged between a first messaging station and a second messaging station. At the observing station, a first time of arrival of the first FTM message and a second time of arrival of the second FTM message may be determined. Based on contents of one or more FTM messages, a first transmission-related time associated with the first FTM message and a second transmission-related time associated with the second FTM message may be obtained. The position of the observing station may be estimated based on (1) a position of the first messaging station, (2) a position of the second messaging station, (3) the first time of arrival, (4) the second time of arrival, (5) the first transmission-related time, and (6) the second transmission-related time.

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.
