Understanding Smart RF and Channel Width
Extreme Campus Controller Smart RF can ensure that the operating channel width does not conflict
with radio band compliance limitations. Your channel width selection is considered when determining
the optimum channel width, but it is not guaranteed. Extreme Campus Controller Smart RF uses data
from the Neighbor Report to determine the best channel width. If your selected channel width is
restricted by radio band compliance, Smart RF selects the next lower channel width. The minimum
width is 20 MHz.
Important
If the channel plan does not include a channel width that meets compliance restrictions, the
radio channel is disabled.
Smart RF runs the assessment for best channel while considering your desired channel width. The
highest channel width (160 MHz) is selected by default for 5 GHz and 6 GHz radios. To allow Smart RF
to determine the best possible channel width without you providing a desired width, select 160 MHz
and Smart RF will automatically reduce the width as appropriate to configure the optimum width,
provided that the AP model supports 160 MHz.
Note
Imported configurations previously set to Auto automatically convert to 160 MHz and are
reduced appropriately.

Configuring a Channel Plan
If ACS or Smart RF is enabled you can define a channel plan for the AP. Defining a channel plan enables
you to control which channels are available for use during an ACS or Smart RF scan. For example, you
may want to avoid using specific channels because of low power, regulatory domain, or radar
interference.
• For 2.4 GHz Radio nodes, select one of the following:
◦ 3 Channel Plan — ACS scans the following channels: 1, 6, and 11 in North America, and 1, 7, and 13
in the rest of the world.
◦ 4 Channel Plan — ACS scans the following channels: 1, 4, 7, and 11 in North America, and 1, 5, 9,
and 13 in the rest of the world.
◦ Auto — ACS scans the default channel plan channels: 1, 6, and 11 in North America, and 1, 5, 9, and
13 in the rest of the world.
◦ Custom — If you want to configure individual channels from which the ACS or Smart RF selects
an operating channel, select Configure. The Add Channels dialog is displayed. Select the
