9.7 Technical Reference

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.

Enable 5-GHz

DFS Aware

Select this if your APs are operating in an area known to have RADAR

devices. This allows the device to downgrade its frequency to below 5

GHz in the event a RADAR signal is detected, thus preventing it from

interfering with that signal.

Enabling this forces the AP to select a non-DFS channel.

5-GHz Channel
