Abstract
Systems and methods are described herein for determining the presence of radar signals within the 5 GHz band using an active communications channel and a portion of the channels adjacent to the active channel. The access point radio may collect the bandwidth of the active and adjacent channels concurrently to avoid having to tune to each channel separately. Further, the radar scanning and a portion of the active channel processing may be completed simultaneously to improve access point utilization.
