Abstract: Embodiments of a system and method for establishing a physical location of a device are generally described herein. In some embodiments a device may include a wireless device configured to communicate with an access point through the use of a wireless protocol, and to perform a method for time-of-flight (ToF) positioning that includes a three-stage fine-timing measurement (FTM) procedure that includes: a first stage for negotiating comeback timing for a next FTM exchange, a second stage that includes performing a fine timing measurement exchange and optionally negotiating the comeback timing for the next fine timing measurement exchange, and a third stage that includes reporting and polling the timestamp of the previous fine timing measurement exchange and optionally performing an additional fine timing measurement stage. In some embodiments a module in a device may determine a range between the device and the access point or the one or more network devices.
