Do Huawei APs support automatic power adjustment? How do they implement it? Why cannot automatic power adjustment implement high-density access

4

Huawei APs support automatic power adjustment. An AP detects neighboring APs and reports neighbor information including the AP channel and receive power. The AC calculates the optical power based on the neighbor information.

Automatic power adjustment enables user access in certain scenarios. Automatic power adjustment reduces signal interference between APs, but it cannot meet the requirements of high-density access. High-density access is restricted by not only signal interference but other factors such as STA transmit power, AP load balancing, and the maximum number of users on an AP.

Automatic power adjustment cannot meet user access requirements in high-density coverage scenarios
Automatic power adjustment enables user access in certain scenarios. This mechanism reduces the interference from an AP to surrounding APs. Service requirements in a high-density access scenario cannot be met by simply adjusting an AP's transmit power. In high-density access scenarios, services are affected by signal interference and other factors, such as the transmit power of APs, AP load balancing, and access capacity of an AP.

Mechanism of automatic transmit power adjustment for APs
APs support automatic adjustment of the transmit power, and the adjustment mechanism is similar to AP channel calibration. In AC+Fit AP networking, when an AP goes offline, the AC adjusts the power of neighboring APs to compensate for the coverage hole.

Do APs support power adjustment and what is the power adjustment mechanism
Power adjustment is similar to channel adjustment. When an AP goes offline, the AC adjusts the power of neighboring APs to compensate for the coverage hole.

How does an AP adjust the rate
When signal quality becomes bad, an AP changes the modulation mode to reduce the transmission rate. This also reduces the bit error ratio.
