The core of the dynamic channel adjustment algorithm is the iterative exhaustive algorithm, iterating all possible "AP-channel" combinations, and finally selecting a set of optimal combinations.

The goal of the TPC algorithm is to select an appropriate transmit power to meet the coverage requirements of the AP.

The minimum interference threshold means that the interference strength to the neighbor is very low, the interference is acceptable, and the two APs are not aware of each other and can simultaneously transmit messages.

If the interference of the neighbor is less than the minimum interference threshold, determine whether to reduce the transmit power according to the difference between the two.

False

After Layer 3 roaming is performed, the VLAN IDs in the service set of APs are changed.

If the VLAN IDs before and after roaming are the same, the STA roams at Layer 2.

Layer 2 roaming indicates that STAs roam within the same subnet.

Layer 3 roaming indicates that STAs roam between different subnets.
