The stations are capable of switching their operating frequency channel 
dynamically when roaming between Access Points RLMs that have been 
configured to use different radio channels.
Using different channels enables you to optimize wireless performance, 
assigning different frequency channels to neighboring Access Points RLMs. 
Multiple frequency configurations may prove very useful in environments 
where:
A high concentration of wireless stations are operational.
The stations experience a performance decrease in terms of network 
response times as a result of the collision avoidance protocol (for more
