Abstract: Disclosed are techniques for performing ranging operations between an access point and an unassociated mobile device. The techniques can include receiving, at an access point, a broadcast probe request from a mobile device unassociated with the access point. In response to receiving the probe request, it can be determined that the mobile device is capable of performing ranging operations including inspecting the received broadcast probe request. The access point can send a ranging request to the mobile device.
