Abstract: In an example embodiment, a wireless device is operable to advertise a policy on the inclusion of the wireless device in a radio frequency map. For example, the wireless device may transmit a signal comprising a field in an extended capabilities information that indicates whether mapping of the wireless device is permissible. As another example, the wireless device may perform certain actions, such as changing media access control address, changing transmit power, and/or vary response times to prevent accurate mapping of the location of the wireless device.
