Chapter 10 AP Profile Table 50 Configuration > Object > AP Profile > Add/Edit Profile (continued) LABEL DESCRIPTION 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 channelhopping to these three "safe" channels. Enable 5 GHz DFS Aware 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 NWA/WAC uses channels 1, 4, 7, 11 in this configuration; otherwise, the NWA/WAC 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. 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. 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 NWA/WAC switches between for 5 GHz operation. Select Auto to have the NWA/WAC automatically select the best channel. Select manual to select the individual channels the NWA/WAC 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. Time Interval DCS Time Interval Select the channels that you want the NWA/WAC to use. Select this option to have the NWA/WAC survey the other APs within its broadcast radius at the end of the specified time interval. This field is available when you set Channel Selection to DCS and select the Time Interval option. Schedule Start Time Week Days Advanced Settings Guard Interval Enter a number of minutes. This regulates how often the NWA/WAC 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 NWA/WAC will then dynamically select the next available clean channel or a channel with lower interference. Select this option to have the NWA/WAC survey the other APs within its broadcast radius at a specific time on selected days of the week. Specify the time of the day (in 24-hour format) to have the NWA/WAC use DCS to automatically scan and find a less-used channel. Select each day of the week to have the NWA/WAC use DCS to automatically scan and find a less-used channel. 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. NWA / WAC Series User's Guide 112

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

and set

5 GHz Channel

Selection Method

manual

Select the channels that you want the NWA/WAC to use.

Time Interval

Select this option to have the NWA/WAC 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

DCS

and select the

Time Interval

option.

Enter a number of minutes. This regulates how often the NWA/WAC 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 NWA/WAC will then dynamically select the next

available clean channel or a channel with lower interference.

Schedule

Select this option to have the NWA/WAC 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 NWA/WAC use DCS to

automatically scan and find a less-used channel.

Week Days

Select each day of the week to have the NWA/WAC 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

long

. This option isn’t applicable

if you set

802.11 Band

11a

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.
