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.
