What is the main goal of Radio Resource Management (RRM) in Cisco WLANs?

RRM is the automated alternative to manual channel configuration - using RRM means the WLC manages channel selection dynamically rather than requiring administrator manual input.

Cisco RRM encompasses three key automated functions - Dynamic Channel Assignment (DCA) selects optimal channels to minimize interference, Transmit Power Control (TPC) adjusts AP power levels to prevent coverage holes and excessive overlap, and Coverage Hole Detection and Correction identifies and compensates for areas with insufficient signal. These work continuously and adapt to changing RF conditions without manual intervention.

Antenna gain is a fixed physical characteristic of the antenna hardware and cannot be changed by software features like RRM.

Client roaming decisions are primarily client-driven or handled by mechanisms such as 802.11r fast BSS transition - RRM manages AP-side RF parameters, not individual client association decisions.
