Dynamic Channel Selection
22.1  Overview
This chapter discusses how to configure dynamic channel selection on the NWA.
Dynamic channel selection is a feature that allows your NWA to automatically 
select the radio channel upon which it broadcasts by scanning the area around and 
determining what channels are currently being used by other devices.
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. This can make accessing the network potentially 
rather difficult for the stations connected to them. 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 interferrence) in order to give the connected 
stations a minimum degree of cross-channel interference.
