11n and 11ac Parameters

Parameters Description
11n Supported Displays whether 802.11n is supported.
11ac Supported Displays whether 802.11ac is supported. This field appears only for 802.11ac slave radios on slot 2.

Clean Air

Parameters Description
Clean Air Capable Displays the CleanAir capability of the access point. Whether the access point is CleanAir capable.
Clean Air Admin Status Displays the Status of the CleanAir admin that you can enable or disable. The default is disabled.

Antenna Parameters

Parameters Description
Antenna Type Internal or external antenna type.

RF Channel Assignment

Parameters Description
Current Channel Displays the channel number of the access point.
Channel Width Set the RF channel assignment method to Custom, and select one of the following channel widths:
  • 20 MHz—Enables the radio to communicate using only 20-MHz channels. Choose this option for legacy 802.11a radios, 20-MHz 802.11n radios, or 40-MHz 802.11n radios that you want to operate using only 20-MHz channels. This is the default value.
  • 40 MHz—Enables 40-MHz 802.11n radios to communicate using two adjacent 20-MHz channels bonded together. The radio uses the primary channel that you choose from the Assignment Method drop-down list as well as its extension channel for faster throughput. Each channel has only one extension channel (36 and 40 are a pair, 44 and 48 are a pair, and so on). For example, if you choose a primary channel of 44, the Switch would use channel 48 as the extension channel. If you choose a primary channel of 48, the Switch would use channel 44 as the extension channel.
  • 80 MHz—Enables the radio to communicate using 80-MHz channels. This option is supported only for 802.11ac capable radios. 802.11ac channelization uses four adjacent 20-MHz channels. From the drop-down list you can select the primary channel and based on the available channel pairing, appropriate secondary 20-MHz and secondary 40-MHz extension channels can be configured for the radio.
Note    To select the channel width as 80-MHz, 802.11ac support must be enabled in WIRELESS > 802.11a/n/ac > High Throughput (802.11n/ac).
Assignment Method Assignment method that you can choose:
  • Global—Use this setting if you set the channel of the access point globally by the Switch.
  • Custom—Use this setting if you set the channel locally. Choose a channel from the drop-down list.
Note   

The assignment method should be left at the global setting to enable the Switch to dynamically change the channel number based Radio Resource Management (RRM) directives.

Tx Power Level Assignment

Parameters Description
Current Tx Power Level Displays the transmission power level of the access point. Tx Power Level indicates the maximum power.
Note    The power levels and available channels are defined by the Country Code setting and are regulated on a country-by-country basis.
Assignment Method Assignment method that you can choose:
  • Global— Use this setting if you set the transmit power of the access point globally by the Switch.
  • Custom— Use this setting if the transmit power of the access point is set locally. Choose an option from the drop-down list.

Note
The assignment method should be left at the global setting to enable the Cisco WLC to dynamically change the transmit power level based on the Radio Resource Management (RRM).
