Abstract: An access point in a wireless network communicates wirelessly with one or more client devices over a channel that includes a plurality of subchannels. Radar is detected on a first subchannel of the plurality of subchannels. It is determined to puncture the first subchannel, based on the detecting the radar on the first subchannel and based on one or more puncturing factors. The first subchannel is punctured, the puncturing comprising muting one or more subcarriers on the first subchannel.

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.

Abstract: In one embodiment, a method is performed. An access point (AP) device may communicate signaling relating to a client device allocation for a location-related measurement. The AP device may transmit a trigger frame. The AP device may receive a response to the trigger frame from a client device. The response may include an uplink orthogonal frequency division multiple access (OFDMA) transmission. A location-related measurement of the client device may be determined based on the response to the trigger frame.

Abstract: In one embodiment, a method is performed. A first wireless access point (AP) device may generate a timing synchronization frame. The timing synchronization frame may include a target beacon transmission time (TBTT) associated with the first wireless AP device. The first wireless AP device may transmit the timing synchronization frame to a second wireless AP device. The first and second wireless AP devices may be synchronized using the timing synchronization frame.
