When numerous APs broadcast within a given area, they introduce the possibility of heightened radio
interference, especially if some or all of them are broadcasting on the same radio channel. If the
interference becomes too great, then the network administrator must open his AP configuration options
and manually change the channel to one that no other AP is using (or at least a channel that has a
lower level of interference) in order to give the connected stations a minimum degree of interference.
Dynamic channel selection frees the network administrator from this task by letting the AP do it
automatically. The AP can scan the area around it looking for the channel with the least amount of
interference.
In the 2.4 GHz spectrum, each channel from 1 to 13 is broken up into discrete 22 MHz segments that are
spaced 5 MHz apart. Channel 1 is centered on 2.412 GHz while channel 13 is centered on 2.472 GHz.
