Abstract: In an example embodiment, a neighbor radio/access point (AP) list is obtained. The neighbor AP list is optimized for a client that is associated with a current access point. The list may be optimized based on any one or combination of techniques, including but not limited to roaming patterns of previous clients that were associated with the current access point, radio frequency metrics, bandwidth requirements for the client, and/or any other suitable criteria. In particular embodiments, requests from the client to associate with an access point that is not on the optimized neighbor AP list may be denied.

Abstract: In an example embodiment, the orientation of a wireless device, such as an access point (AP) can be determined based on the location of neighboring wireless devices and the observed angle of arrival of signals from the wireless device at the neighboring wireless devices. For example, the angle of orientation can be determined by comparing an observed angle of arrival with the known actual angle between wireless devices. If a plurality of wireless devices measure the signal, the mean or median of the difference between observed angle of arrival of a signal from the wireless device with the actual angle for the plurality of wireless devices may be employed to determine the angular orientation.

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 map 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.
