Chapter 22 Dynamic Channel Selection

In this example, if the NWA attempts to broadcast on channels 1, 2, or 3 it is met with cross-channel interference from the other AP that shares the channel. This can result in noticeably slower data transfer rates, the dropping of the connection altogether, or even lost data packets.

However, if the NWA broadcasts on the otherwise empty channel 4 then there will be minimal interference and a clearer connection to the network.

To alleviate this problem of having to manually change channels every time interference crops up, you would normally need to scan the area quite often to see which channels are currently unused then set your device to use one of them. But with Dynamic Channel Selection, the NWA does this automatically.
