Chapter 9 Wireless Table 43 Configuration > Wireless > DCS (continued) LABEL DESCRIPTION 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. 5-GHz Channel Selection Method Enabling this forces the AP to select a non-DFS channel. Select how you want to specify the channels the NWA3000-N series AP switches between for 5 GHz operation. Select auto to have the NWA3000-N series AP automatically select the best channel. Apply Reset Select manual to select the individual channels the NWA3000-N series AP switches between. Select channels from the Available channels list and use the right arrow button to move them to the Channels selected list. Click Apply to save your changes back to the NWA3000-N series AP. Click Reset to return the screen to its last-saved settings. 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. 124 NWA3000-N Series User's Guide

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.

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.
