--> Radio Resource Management allows Wireless Controller to continuously analyze the existing RF environment, automatically adjust AP power levels and channel configurations to help mitigate co-channel interference and signal coverage problems.
--> RRM uses three main algorithms to prevent interference and channel problems.
i) Transmit Power Control -- used to provide optimal AP power levels based upon AP placement and signal levels.
ii) Coverage Hole Detection -- used to increase AP Power levels in response to weak client signals.
iii) Dynamic Channel Assignment -- used to select best channel for the AP depending upon wireless network.
--> Each and every algorithm runs separately for each band ( separate for 2.4 GHZ/ 5 GHZ).
--> Each and Every Controller is configured with RF Group Name.
--> Once the RF Group is created then we need to determine which WLC should be RF Group leader.
--> RF Group leader runs Dynamic Channel Assignment and Transmit Power Control algorithms for whole group.
--> Leader configuration can be done separately per band ( 2.4 Ghz / 5 Ghz).
--> Each and Every AP will joins RF Group and Send information to other AP and Controllers.
--> Every Access Point Periodically sends information ( AP info, Controller IP, RF Group name) to its neighbors ( other AP).
--> The AP's which receive information simply forwards this to controller, now controller has total idea of RF environment.
