Abstract: Techniques for establishing a fine timing measurement (FTM) session of infinite duration between wireless devices is provided. A method according to these techniques includes generating, at a first wireless device, a first request to establish an FTM session with a second wireless device using an FTM protocol, the first request comprising one or more session parameters having a value indicative that the first wireless device is requesting the FTM session have an infinite session duration, receiving one or more FTM measurement messages from the second wireless device, and sending a second request to the second wireless device requesting that the FTM session be terminated.

Abstract: Techniques for context aware connections to a wireless network are disclosed. An example of an apparatus for wireless communication includes a first interface configured to receive neighbor report information from one or more wireless nodes, a processing system configured to generate a beacon frame, generate a neighbor report based on the received neighbor report information, a second interface configured to output the beacon frame for transmission, and output the neighbor report as an unsolicited frame after outputting the beacon frame.

Abstract: Techniques for providing a secure Fine Timing Measurement (FTM) exchange between two wireless transceivers are disclosed. An example of a method according to the disclosure include transmitting a protected FTM range request message with a Dialog Token of a FTM frame, receiving a protected FTM range report message from a station, wherein the protected FTM range report message includes FTM information, and authenticating the station based at least in part on the FTM information included in the protected FTM range report message.

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.
