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.
