Basically how it works is that you have to listen for radars using the channel, and if you hear one, you have to get off the channel within a certain number of milliseconds. But DFS systems don't switch channels in response to other Wi-Fi networks, nor do they switch channels in order to optimize aggregate bandwidth.
