Configure Smart RF Channel and Power Settings

About this task

Use the Channel and Power dashboard to refine Smart RF power settings over both 5 and 2.4 GHz radios and select channel settings in respect to the device channel usage.

Note

The Chennal and Power Settings parameters are activated only when Custom or Medium is selected as the Sensitivity setting from the Smart RF Basic dashboard.

Procedure

Select Policies > Smart RF.
A set of existing Smart RF policy list opens.
Select a Smart RF policy.
Select Channel and Power.

Refer to the Power Settings field to define Smart RF recovery settings for the selected 5.0 GHz (802.11a) or 2.4 GHz (802.11bg) radio.


5 GHz Minimum Power	Use the spinner control to select a 1 dBm to 20 dBm minimum power level for Smart RF to assign to a radio in the 5.0 GHz band. The default setting is 4 dBm
5 GHz Maximum Power	Use the spinner control to select a 1 dBm to 20 dBm maximum power level Smart RF can assign a radio in the 5.0 GHz band. The default setting is 17 dBm
2.4 GHz Minimum Power	Use the spinner control to select a 1 dBm to 20 dBm minimum power level Smart RF can assign a radio in the 2.4 GHz band. The default setting is 4 dBm
2.4 GHz Maximum Power	Use the spinner control to select a 1 dBm to 20 dBm maximum power level Smart RF can assign a radio in the 2.4 GHz band. The default setting is 17 dBm

Set the following Channel Settings for the 5.0 GHz and 2.4 GHz radios.


5 GHz Channels	Use the drop-down list box to define the 5 GHz channels used for Smart RF assignments
5 GHz Channel Width	20 MHz, 40 MHz, and 80 MHz channel widths are supported by the 802.11a radio. 20 MHz, 40 MHz, or 80 MHz operation (the default setting for the 5 GHz radio) allows the access point to receive packets from clients using 20 MHz of bandwidth while transmitting a packet using 40 MHz bandwidth. This mode is supported for 11n users on both the 2.4 and 5 GHz radios. If an 11n user selects two channels (a primary and secondary channel), the system is configured for dynamic 20/40 operation. When 20, 40, 80 is selected, clients can take advantage of wider channels. 802.11n clients experience improved throughput using 40 MHz while legacy clients (either 802.11a or 802.11b/g depending on the radio selected) can still be serviced without interruption using 20 MHz. Select Automatic to enable automatic assignment of channels to working radios to avoid channel overlap and avoid interference from external RF sources. Automatic is the default setting. 80 MHz channel is used for 802.11ac access points
2.4 GHz Channels	Set the 2.4 GHz channels used in Smart RF scans
2.4 GHz Channel Width	20 MHz and 40 MHz channel widths are supported by the 802.11a radio. 20 MHz is the default setting for 2.4 GHz radios. 20 MHz or 40 MHz operation (the default setting for the 5 GHz radio) allows the access point to receive packets from clients using 20 MHz of bandwidth while transmitting a packet using 40 MHz bandwidth. This mode is supported for 11n users on both the 2.4 Ghz and 5 GHz radios. If an 11n user selects two channels (a primary and secondary channel), the system is configured for dynamic 20 MHz or 40 MHz operation. When 20 MHz or 40 Mhz is selected, clients can take advantage of wider channels. 802.11n clients experience improved throughput using 40 MHz while legacy clients (either 802.11a or 802.11b/g depending on the radio selected) can still be serviced without interruption using 20 MHz. Select Automatic to enable automatic assignment of channels to working radios to avoid channel overlap and avoid interference from external RF sources. Automatic is the default setting

Select Add to create new area based channel settings.
The Settings window opens.

Configure the following Area Based Channel Settings for the Smart RF policy:


Name	Specify the deployment area assigned to the listed policy when deployed as a means of identifying the device's physical locations
Band	Select the radio band, either 2.4 GHz or 5 GHz, for the Smart RF policy assigned to the specified area
Channel List	Select the channels associated with the Smart RF policy for the specified area and band

Select Add to update area based channel settings.
Select to delete an existing area based channel setting.
Select Save to update channel and power settings for this Smart RF policy.
