Abstract
A computing device initiates wireless RTT ranging communication with a wireless device by specifying a source address (e.g., a MAC address or BSSID) of the wireless device in frames sent to the wireless device. The computing device determines situations in which a wireless device is using multiple source addresses. If a wireless device is using multiple source addresses, the computing device performs wireless RTT ranging with the wireless device using less than all (e.g., a single one) of the multiple source addresses. The computing device performs wireless RTT ranging with less than all of the source addresses used by the wireless device because the distance between the computing device and the wireless device is the same regardless of which of the multiple source addresses the wireless device is using.
