Usage Guidelines

Usage Scenario

After you run the scan-channel-set command to specify an air scan channel set for an AP, the AP scans channels in the channel set. The collected information is reported to the AC or server for radio calibration, smart roaming, spectrum analysis, terminal location, or WIDS data analysis.

Precautions

If the air scan channel set you specified contains all channels supported by the country code of the AP, the AP scans data on many channels but the channel scanning lasts for a long time, which may affect real-time data analysis.
If you specify a calibration channel set as the air scan channel set, the AP scans data on a few channels. This reduces the channel scanning time, increases the terminal location accuracy, and reduces burden on the device.
If you add only working channels of an AP to the air scan channel set, the AP only scans the working channels.
