Usage Guidelines

Usage Scenario

After the air scan period is configured using the scan-period command, an AP continuously scans surrounding radio signals in the configured period. After the period expires, the AP reports the collected information to an AC or server. The information is used for radio calibration, smart roaming, spectrum analysis, WLAN location, or WIDS data analysis.

In spectrum analysis scenarios, to obtain enough sampling data, it is recommended that the scanning interval be set no more than 10 seconds and the scanning duration to 100 ms.

Precautions

A longer air scan period indicates more collected data and a more accurate data analysis result. However, if the air scan period is set too large, WLAN services are affected. You are advised to use the default value.

Example

# Set the air scan period to 80 ms for APs.
