Understanding Smart RF and Channel Width

ExtremeCloud IQ 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. ExtremeCloud IQ 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.

Smart RF runs the assessment for best channel while considering your desired channel width. The highest channel width 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.
