Abstract: In an example embodiment disclosed herein there is described a multi-radio device which comprises a first radio that first radio comprises a transmitter, and a second radio that second radio comprises a receiver that monitors a channel to obtain data representative of a predefined channel parameter. The second radio is operable to receive a signal from the first radio that indicates when the transmitter of the first radio is transmitting. The receiver of the second radio selectively excludes data representative of a predefined channel parameter based on whether the transmitter of the first radio is transmitting.

Abstract: In an example embodiment, a channel that includes a plurality of sub-channels is sampled to detect pulses indicative of a presence of a radar signal. A frequency for the radar signal is determined. If the frequency of the radar signal maps to a selected subset of the plurality of sub-channels, the selected subset of the plurality of sub-channels are determined to be unavailable due to radar, while the remaining sub-channels remain available for use. The selected subset of the plurality of sub-channels determined to be unavailable due to radar may be selectively returned for use after the radar signal is no longer detected for a predetermined selected time period.

Abstract: In one embodiment, a method implemented on an access point of a wireless communication system includes: determining an estimate for a relative velocity between a mobile wireless client device and the access point, the mobile wireless client device communicating wirelessly with the access point over a channel; determining a channel coherence time for the channel using said estimated relative velocity; and determining a maximum aggregated frame size based on the determined channel coherence time.
