Can Huawei WLAN devices automatically select channels with higher quality

3

Huawei APs support automatic channel selection. However, in large-scale AP deployment, channels are planned before deployment. Changing one AP's channel will cause channel switching on other APs, affecting wireless services on the entire network. Therefore, automatic channel selection is not recommended.

Channel planning for WLAN devices
There are limited non-overlapping channels on the 2.4 GHz frequency band. If channels of neighboring APs conflict, channel interference occurs and user access experience is degraded. You are advised to plan channels as follows: - Make an AP channel plan before performing data configurations. You are advised to manually configure AP channels. Automatic channel adjustment is not recommended. - If channels of neighboring APs from other vendors conflict with those of Huawei APs, negotiate with the vendors to change overlapping channels. - Use spatial staggered channels to increase network capacity. - Channels of neighboring APs are staggered. For example, the 2.4 GHz radio channels are deployed in a fixed sequence of 1-6-11-1-6-11. - The 5 GHz frequency band is preferred when it is allowed. On the 5 GHz frequency band, non-overlapping channels in HT20 mode include channels 149, 153, 157, 161, and 165.

How to configure channels and power for WLAN devices
Configure radio channels and power for WLAN devices manually or by configuring radio calibration. -Manual configuration Take the configuration on the AC as an example. Users can adjust the channel and power using the channel 20mhz xx and power-level commands.

Version selection and requirements for the WLAN device upgrade
How do signal measurement tools calculate the SNR? Does a higher SNR value indicate a better signal quality
The SNR value obtained using a signal measurement tool is not the actual SNR on a network adapter. The tool obtains the SNR value by comparing the detected signal strength with a predefined noise value (-96 dBm for example). A high SNR value does not indicate a good signal quality because the high SNR may be caused by interference signals. The signal quality should be evaluated by the SNR and signal to interference ratio (SIR).
