Load balancing between the 2.4 GHz and 5 GHz radios is considered in band steering. An AP determines the radio with which a STA preferentially associates based on numbers of access users on the 2.4 GHz and 5 GHz radios.

Check whether the number of access users on an AP exceeds the start threshold for load balancing between radios. If not, STAs can preferentially associate with the 5 GHz radio.

If the number of access users on an AP exceeds the start threshold for load balancing between radios, the AP determines the frequency band to which the STA connects based on radio load difference computed according to the formula (Number of access users on the 5 GHz radio -Number of access users on the 2.4 GHz radio/Number of access users on the 5 GHz radio x 100%).

After the number of users associated with an AP reaches the start threshold for load balancing between radios, if the value obtained based on the formula (Number of access users on the 5 GHz radio - Number of access users on the 2.4 GHz radio/Number of access users on the 5 GHz radio x 100%) is greater than the gap-threshold value, the AP preferentially associates with the STA on the 5 GHz radio.

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.
