The following section contains additional technical information about the features described in this 
chapter.
Dynamic Channel Selection
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.
