Chapter 19 AP Profile
NXC Series User’s Guide

Channel
Selection
Select the wireless channel which this radio profile should use.
It is recommended that you choose the channel least in use by other APs in the region
where this profile will be implemented. This will reduce the amount of interference between
wireless clients and the AP to which this profile is assigned.
Select DCS to have the AP automatically select the radio channel upon which it
broadcasts by scanning the area around it and determining what channels are currently
being used by other devices.
Note: If you change the country code later, Channel Selection is set to Manual
automatically.
Select Manual and specify the channels the AP uses.
Blacklist DFS
channels in
presence of radar
This field is available if 802.11 Band is set to 5G and Channel Selection is set to DCS.
Enable this to temporarily blacklist the wireless channels in the Dynamic Frequency
Selection (DFS) range whenever a radar signal is detected by the AP.
Enable DCS
Client Aware
This field is available when you set Channel Selection to DCS.
Select this to have the AP switch channels only when there are no clients connected to it. If
there is a client connected, the AP will not switch channels but generate a log. The AP tries
to scan and switch channels again at the end of the specified time interval or at the
scheduled time.
If you disable this then the AP switches channels immediately regardless of any client
connections. In this instance, clients that are connected to the AP when it switches
channels are dropped.
2.4 GHz Channel
Selection Method
This field is available when you set Channel Selection to DCS.
Select auto to have the AP search for available channels automatically in the 2.4 GHz
band. The available channels vary depending on what you select in the 2.4 GHz Channel
Deployment field.
Select manual and specify the channels the AP uses in the 2.4 GHz band.
Note: The method is automatically set to auto when no channel is selected or
any one of the previously selected channels is not supported.
Channel ID This field is available only when you set Channel Selection to DCS and set 2.4 GHz Channel
Selection Method to manual.
Select the check boxes of the channels that you want the AP to use.
2.4 GHz Channel
Deployment
This field is available only when you set Channel Selection to DCS and set 2.4 GHz Channel
Selection Method to auto.
Select Three-Channel Deployment to limit channel switching to channels 1,6, and 11, the
three channels that are sufficiently attenuated to have almost no impact on one another.
In other words, this allows you to minimize channel interference by limiting channel-
hopping to these three “safe” channels.
Select Four-Channel Deployment to limit channel switching to four channels. Depending
on the country domain, if the only allowable channels are 1-11 then the NXC uses channels
1, 4, 7, 11 in this configuration; otherwise, the NXC uses channels 1, 5, 9, 13 in this
configuration. Four channel deployment expands your pool of possible channels while
keeping the channel interference to a minimum.
