Channel
Selection
This is the radio channel which the signal will use for broadcasting by this radio profile.
•
DCS
: Choose Dynamic Channel Selection to have the Zyxel Device choose a radio
channel that has least interference.
•
Manual
: Choose from the available radio channels in the list. If your Zyxel Device is
outdoor type, be sure to choose non-indoors channels.
Note: The available SSID broadcast channels in the 6 GHz band are PSCs
(Preferred Scanning Channels). See
Enable DCS
Client Aware
This field is available when you set
Channel Selection
to
DCS
.
Select this to have the Zyxel Device switch channels only when there are no clients
connected to it. If there is a client connected, the Zyxel Device will not switch channels but
generate a log. The Zyxel Device 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 Zyxel Device switches channels immediately regardless of any
client connections. In this instance, clients that are connected to the Zyxel Device when it
switches channels are dropped.
2.4 GHz Channel
Selection Method
This field is available when you set
Channel Selection
to
DCS
.
Select how you want to specify the channels the Zyxel Device switches between for 2.4
GHz operation.
Select
auto
to have the Zyxel 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 Zyxel Device 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
2.4 GHz Channel
Selection Method
to
manual
.
Select the channels that you want the Zyxel Device to use.
2.4 GHz Channel
Deployment
This is available when you set
Channel Selection
to
DCS
and 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 Zyxel Device uses
channels 1, 4, 7, 11 in this configuration; otherwise, the Zyxel 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.
Enable 5 GHz DFS
Aware
This field is available only when you select
5G
in the
802.11 Band
field, set
Channel
Selection
to
DCS
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 Zyxel 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.
