|
Step 6
|
Expand Basic Settings.
|
Step 7
|
In the Radio Frequency Settings area, check the 2.4 GHz, 5 GHz, or 6 GHz check box.
The radio frequencies are checked by default. If you uncheck a radio frequency, the RF settings are disabled for that radio
frequency.

|
|
Step 8
|
In the Busy Hours area, define the start and end time of the site time zone.
Note
|
Busy hours are dependent upon the time zone of the building. You must configure a timezone under network settings for the
respective building.
|
|
Step 9
|
In the Busy Hour Sensitivity area, click the Low, Medium, or High radio button to define the threshold of Radio Resource Management (RRM) sensitivity for the busy hours interval.
|
Step 10
|
In the Enable RF Settings area, click the toggle buttons under the 2.4 GHz, 5 GHz, or 6 GHz columns to enable or disable the radio band for the respective RF setting.
The supported RF settings are:
-
Flexible Radio Assignment (FRA): FRA optimizes the radio coverage per band and determines the best role assignment for redundant radios.
-
Dynamic Channel Assignment (DCA): DCA dynamically manages channel assignment for an RF group and evaluates the assignments on a per-AP radio basis.
-
Transmit Power Control (TPC): TPC manages and transmits power for APs. It also maximizes the SNR during the reduction in interference.
-
Dynamic Bandwidth Selection (DBS): DBS monitors and adjusts the channel width to balance the performance and interference.
Note
|
-
When you disable the 2.4 GHz radio band for FRA, it automatically disables the 5 GHz radio band for FRA, and conversely.
-
When you disable the 5 GHz radio band for DCA, it disables the 2.4 GHz radio band for FRA and the 5 GHz radio band for FRA
and DBS.
-
You can individually enable the 2.4 GHz radio band for DCA and TPC; and the 5 GHz radio band for DCA, TPC, and DBS.
-
You can enable or disable the 6 GHz radio band together for DCA and DBS RF settings.
-
FRA is not supported for the 6 GHz radio band.

-
Power Level: Determines whether the power of an AP needs to be reduced. Reducing the power of an AP helps mitigate co-channel interference.
-
Power Threshold: Is the cutoff signal level used by RRM to determine whether to reduce the power of an AP.
-
RX SOP: Receiver Start of Packet Detection Threshold (RX SOP) determines the Wi-Fi signal level, in dBm, at which an AP's radio
demodulates and decodes a packet.
