Performing round trip time ranging using fewer than all addresses of a wireless device

A computing device comprising:

• a processor;
• and
• a computer-readable storage medium having stored thereon multiple instructions that implement an energy conserving round trip time (RTT) ranging system and that, responsive to execution by the processor, cause the processor to perform acts including:
• receiving a source address list from an application on the computing device, the source address list identifying multiple source addresses with which the application desires the computing device to be RTT ranged;
• identifying two or more source addresses on the source address list that are used by a single wireless device to communicate management frames;
• generating a source address set identifying multiple sources addresses with which the computing device is to be RTT ranged, the generating comprising including only one of the two or more source addresses in the source address set;
• and
• performing wireless RTT ranging with the single wireless device using the selected one of the two or more source addresses but fewer than all of the two or more source addresses, the performing wireless RTT ranging with the single wireless device including communicating multiple frames to the wireless device and receiving multiple frames from the wireless device.

A method comprising:

• receiving a fast initial link setup (FILS) beacon from a single wireless device;
• determining whether a multiple basic service set identifier (BSSID) support field in the FILS beacon is set to indicate that the single wireless device supports multiple BSSIDs;
• determining, from a BSSID field in the FILS beacon in response to the multiple BSSID support field being set to indicate that the single wireless device supports multiple BSSIDs, multiple source addresses used by the single wireless device;
• selecting one of the multiple source addresses;
• and
• performing, by the computing device, wireless round trip time (RTT) ranging with the single wireless device using the selected one of the multiple source addresses but fewer than all of the multiple source addresses used by the single wireless device to communicate management frames, the performing wireless RTT ranging with the single wireless device including communicating multiple frames to the wireless device and receiving multiple frames from the wireless device.
