Requirements for a radio to join a load balancing group

The access capability of an AP is limited. If a large number of STAs exist in a hotspot area, the user deploys multiple APs in this area to meet requirements of the STAs. In this case, certain APs may be connected to multiple STAs whereas other APs to only a few STAs, resulting in imbalance. To solve this problem, load balancing is used. In load balancing mode, AP radios in a hotspot area are added to a group. When the load is unbalanced in the group, STAs are automatically associated with lightly loaded AP radios but not heavily loaded radios.

The requirements for a radio to join a load balancing group are as follows:

- A radio can join only one load balancing group.

- The newly added radios must be of the same type as other radios in the load balancing group.

Radios in a hotspot area must be of the same type. Otherwise, load balancing cannot be achieved.

The type of radios in a load balancing group is determined by the type of the first added radio.

- The channel of a new radio must be different from channels of other radios in the load balancing group.

If the channel of a new radio is the same as channels of other radios in the load balancing group, a radio signal collision occurs. To improve coverage areas and minimize collisions, APs in a hotspot area must be configured with different channels.

To detect channel collisions, check the configured channel and actual channel of the radio.

- More radios can be added to a load balancing group if it is not full.

In a load balancing group, radios must be configured with different channels and all these radios must be of the same type. In addition, radios of the same type support limited and fixed channels. Therefore, the number of radios in a load balancing group is limited.
