dca-channel bandwidth
Function
The dca-channel bandwidth command configures the calibration bandwidth.
The undo dca-channel bandwidth command restores the default calibration bandwidth.
By default, the calibration bandwidth is 20 MHz.
Usage Guidelines
Usage Scenario
The 5 GHz frequency band has richer spectrum resources. In addition to 20 MHz channels, APs working on the 5 GHz frequency band support 40 MHz and 80 MHz channels. Larger-bandwidth channels mean higher transmission rates. However, at least three channels are required in radio calibration to achieve the optimal calibration effect. When configuring the calibration bandwidth, ensure that enough calibration channels are available for use.
You can use the dca-channel bandwidth command to configure the calibration bandwidth and the dca-channel channel-set command to configure calibration channels as prompted.
Configuration Impact
When the calibration bandwidth is changed, the device recalculates the calibration channels.

When configuring 40 MHz or 80 MHz calibration bandwidth, check whether channels of the corresponding bandwidth exist under the country code.
