Abstract: Some demonstrative embodiments include apparatuses, systems and/or methods of performing a Time of Flight (ToF) measurement. For example, a first wireless device may include a controller to perform a Time of Flight (ToF) measurement procedure with a second wireless device; and a radio to communicate with the second wireless device a ToF frame including a first time value of a Time Synchronization Function (TSF) of a sender of the frame to indicate a beginning time of a ToF measurement period, and a second time value of the TSF at transmission of the ToF frame.

Abstract: Fine Timing Measurement (FTM) Burst Management during Time-of-Flight (ToF) measurements in a wireless network separates FTM traffic from other traffic activity using two distinct Media Access Control (MAC) addresses and by coordinating access availability durations between FTM activity and other traffic. Communication stations save power by powering down receive paths between FTM frames. A communication station arranged for FTM Burst Management comprises physical layer circuitry and processors to use a first MAC address for FTM procedure signals, and a second MAC address that is distinct from the first MAC address for data and traffic signals other than FTM procedure signals, and exchange FTM procedure signals with the Access Point (AP) during scheduled FTM burst access availability periods using the first MAC address, and exchange other data and traffic signals with the AP during other access availability periods using the second MAC address.
