CHAPTER 22 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.
