2.4 GHz Channel
Deployment
This is available when the 2.4 GHz Channel Selection Method is set 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 NWA1000 Series
uses channels 1, 4, 7, 11 in this configuration; otherwise, the NWA1000 Series 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.
Enable 5 GHz DFS
Aware
This field is available only when you select 11a, 11a/n or 11ac in the 802.11 Band field and
set 5 GHz Channel Selection Method to auto.
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 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
Selection Method
Select how you want to specify the channels the NWA1000 Series switches between for 5
GHz operation.
Select Auto to have the NWA1000 Series automatically select the best channel.
Select manual to select the individual channels the NWA1000 Series switches between.
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 5 GHz Channel
Selection Method to manual.
Select the channels that you want the NWA1000 Series to use.
Time Interval Select this option to have the NWA1000 Series survey the other APs within its broadcast
radius at the end of the specified time interval.
DCS Time Interval This field is available when you set Channel Selection to DCS and select the Time Interval
option.
Enter a number of minutes. This regulates how often the NWA1000 Series surveys the other
APs within its broadcast radius. If the channel on which it is currently broadcasting suddenly
comes into use by another AP, the NWA1000 Series will then dynamically select the next
available clean channel or a channel with lower interference.
Schedule Select this option to have the NWA1000 Series survey the other APs within its broadcast
radius at a specific time on selected days of the week.
Start Time Specify the time of the day (in 24-hour format) to have the NWA1000 Series use DCS to
automatically scan and find a less-used channel.
Week Days Select each day of the week to have the NWA1000 Series use DCS to automatically scan
and find a less-used channel.
Advanced Settings
Guard Interval Set the guard interval for this radio profile to either short or long. This option isn’t applicable
if you set 802.11 Band to 11a or 11b/g and/or choose 20 MHz channel width.
The guard interval is the gap introduced between data transmission from users in order to
reduce interference. Reducing the interval increases data transfer rates but also increases
interference. Increasing the interval reduces data transfer rates but also reduces
interference.
