I have been moving our less AP dense buildings to 40 Mhz channels. In the dorms, I stick with 20 Mhz, unless there is little to no CCI when I do my testing. I see RADAR events, but they are sparse. I definitely see an improvement with the 40 Mhz channels and keeping users connected and happy in our academic areas.
