11. A method for channel selection, the method comprising:
determining a time period when channel traffic for a current operating channel is below a threshold, wherein the current operating channel is a non-DFS channel;
determining a channel score for each of a plurality of Dynamic Frequency Selection (DFS) channels based on local channel statistics information during the determined time period, wherein the local channel statistics information comprises data relating to scans of sub-channels within one or more channels, wherein the channel score for each of the one or more channels comprises a sum of a weighted score for each sub-channel within the one or more channels, and wherein the weighted score for each sub-channel is weighted in accordance with its bandwidth;
determining a best DFS channel based on evaluating the determined channel scores;
triggering one or more wireless devices in a wireless network to switch to the best DFS channel at the time period; and
running in-channel channel availability check for the best DFS channel, and using the best DFS after the in-channel channel availability check is complete.
