What is the minimum adjustment value of radio power for Huawei indoor APs (supporting 2.4 GHz and 5 GHz frequency bands) and outdoor 802.11n APs (supporting only the 2.4 GHz frequency band)

9

The radio power of Huawei APs can be adjusted automatically and manually. APs automatically adjust the radio power to the optimal value based on calculation. The minimum value for manual adjustment is 1 dBm.

Whether the WLAN supports the concurrent dual-band
From V200R001C00 to V200R002C02, the device supports only the 2.4G frequency band but does not support the 5G frequency band. Starting from V200R003C00, the AR201VW-P and AR207VW support both 2.4 GHz and 5 GHz frequency bands but cannot work on the two frequency bands simultaneously. Starting from V200R005C30, the AR510 series can work on 2.4 GHz and 5 GHz frequency bands simultaneously. Starting from V200R006C10, the AR503GW-LM7 can work on 2.4 GHz and 5 GHz frequency bands simultaneously.

Configure 2.4 GHz and 5 GHz radios
Configure 2.4 GHz and 5 GHz radios. In most cases, wlan-radio 0 or radio 0 indicates the 2.4 GHz radio, and wlan-radio 1 or radio 1 indicates the 5 GHz radio. When configuring 2.4 GHz and 5 GHz radios, bind the corresponding radio profiles and service sets. To switch or disable a radio, delete the radio profile and service set bound to the radio. Note: 1. For Fat APs: - Radio profiles: must be added for 2.4 GHz and 5 GHz radios in V200R003, and network types must be selected accordingly. However, this process is not required in V200R005 and later versions. - Service sets: must be created for 2.4 GHz and 5 GHz radios, and be invoked by wireless networks separately. 2. For ACs: - Radio profiles: must be added for 2.4 GHz and 5 GHz radios in V200R003, and network types must be selected accordingly. However, this process is not required in V200R005 and later versions. - Different radios can reuse a service set. 3. The AP2010DN supports only one radio. Change the radio frequency by running the ap id radio 0 command.

Can Huawei 802.11n APs automatically switch between 2.4 GHz and 5 GHz
Huawei 802.11n APs cannot automatically switch between 2.4 GHz and 5 GHz frequency bands. Switching is performed manually.

Minimum granularity for radio power adjustment on indoor settled 802.11n APs
Huawei APs support automatic and manual radio power adjustment. The granularity for automatic adjustment depends on the calculation result for achieving optimal performance. The minimum granularity for manual adjustment is 1 dB.
