An RF Group and its RF NeighbourhoodsThe optimal setting for RF for each AP is monitored by the RRM. Several APs under the RRM algorithm s are considered members of a single logical RF group, and they are under unified administrative control. Since one FP group can configure a single controller, it contains all the APs joints to develop it. A single RF group can span multiple controllers, but only one can run the RRM algorithm for all the APs present in the RF group. In addition, RF neighborhoods are formed by APs contained in one RF group organized by the RRM.

An RF group refers to a logical collection of controllers coordinating to perform the RRM in an optimized manner universally accepted. Its purpose is to calculate network performance based on per-radio. The RMM runs at a default time lap of 600 seconds. RF groups define controllers’ clusters and facilitate system-wide dynamic RF management. Access points validate messages to each other using the RF group name. An RF neighborhood in auto mode is formed automatically when access points on different controllers receive signals from validated neighbor messages with a –80 dBm or stronger signal strength. The RF group leader sends keepalive messages to each of the RF group members and collects real-time RF data
