What Are the Requirements for a Radio to Join a Load Balancing Group?

What Are the Requirements for a Radio to Join a Load Balancing Group?

The capabilities of an AP are 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 are connected to more STAs whereas other APs are connected to a few STAs. To solve this problem, load balancing is used. In load balancing, AP radios in a hotspot area are added into a group. When 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 new 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 radio type in a load balancing group is decided 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, radio signal collision occurs. To minimize collisions, APs in a hotspot area must be configured with different channels.
    • To detect channel collision, check the configured channel and actual channel of the radio.
  • The load balancing group still has the capability to carry radios.
    • 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 the limited and fixed channels. Therefore, the number of radios in a load balancing group is limited.
