Abstract:
An access point (AP) includes a transceiver to service wireless client traffic on wireless channels within a channel bandwidth. The AP services wireless client traffic in a first channel bandwidth and sets a receiver bandwidth to include the first channel bandwidth and a second channel bandwidth initially not available for servicing wireless client traffic. Concurrent with servicing the wireless client traffic in the first channel bandwidth, the AP searches the second channel bandwidth for any interference signal. If no interference signal is found in the second channel bandwidth, the AP declares the second channel bandwidth free of interference.
