A regulatory domain profile provides configurations of country code, calibration channel, and calibration bandwidth for an AP.
- A country code identifies the country to which AP radios belong. Different countries support different AP radio attributes, including the transmit power and supported channels. Correct country code configuration ensures that radio attributes of APs comply with laws and regulations of countries and regions to which the APs are delivered.
- A calibration channel set limits the dynamic AP channel adjustment range when the radio calibration function is configured. Radar channels and the channels that are not supported by STAs are avoided.
- 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. Different calibration bandwidths support different calibration 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.
