Abstract: This disclosure provides systems, methods and apparatus for establishing and maintaining network connections based on ranging information. In one aspect, a wireless device is configured to identify one or more candidate access points (APs) within a vicinity of the wireless device, and exchange fine timing measurement (FTM) frames with candidate APs to determine respective distances between the wireless device and each of the candidate APs. In some aspects, the exchange of FTM frames may be performed when the wireless device is not associated with any AP. In some other aspects, the exchange of FTM frames may be performed when the wireless device is already associated with an existing AP, for example, to determine whether a roaming condition is satisfied. The wireless device then selects one of the candidate APs, based at least in part on the FTM frames, and associates with the selected candidate AP.

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 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: 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: 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.
