DESCRIPTION
Select the AP's sensitivity level toward other channels. Options are High,
Medium, and Low.
Generally, as long as the area in which your AP is located has minimal
interference from other devices you can set the DCS Sensitivity Level to
Low. This means that the AP has a very broad tolerance.
If you are not sure about the number and location of any other devices in the
region, set the level to Medium. The AP's tolerance for interference is
relatively narrow.
On the other hand, if you know there are numerous other devices in the
region, you should set the level to High to keep the interference to a
minimum. In this case, the device's tolerance for interference is quite strict.
Note: Generally speaking, the higher the sensitivity level, the more frequently
the AP switches channels. As a consequence, anyone connected to the
AP will experience more frequent disconnects and reconnects unless
you select Enable DCS Client Aware.
Select this to have the AP wait until all connected clients have disconnected
before switching channels.
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.
Select how you want to specify the channels the device switches between for
2.4 GHz operation.
Select auto to have the device display a 2.4 GHz Channel Deployment field
you can use to limit channel switching to 3 or 4 channels.
Select manual to select the individual channels the device switches between.
Select channels from the Available channels list and use the right arrow
button to move them to the Channels selected list.
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 device uses channels 1, 4, 7, 11 in this configuration; otherwise,
the device 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.
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.
