This section describes the following configuration tasks:

„

Disabling or re-enabling RF load balancing

„

Assigning radios to load balancing groups

„

Specifying band preference for RF load balancing

„

Setting strictness for RF load balancing

„

Exempting an SSID from RF load balancing

RF load balancing is the ability to reduce network congestion over an area 
by distributing client sessions across the MAP with overlapping coverage 
in the area. It allows you to provide the same client experience as if there 
were one nearby MAP with sufficient capacity, even when the total 
demand of nearby clients exceeds the capacity of a single MAP.

For example, in an auditorium or lecture hall, there may be a substantial 
number of clients in a relatively small amount of space. While a single 
MAP may be sufficient for providing an RF signal to the entire area, more 
MAPs are required in order to deliver enough aggregate bandwidth for all 
of the clients. When additional MAPs are installed in the room, RF load 
balancing allows the client sessions to be spread evenly across the MAPs, 
increasing the available aggregate bandwidth by increasing the number 
of MAPs.

RF load balancing is enabled by default. In addition, RF load balancing is 
done on a per-radio basis, rather than a per-MAP basis. For radios that are 
managed by a given radio profile, MSS automatically assesses which 
radios have overlapping coverage in an area and balances the client load 
across them.
