Data Sheet

Intelligent RF Management

The Cisco Wireless LAN controller network module comes equipped with embedded software for

adaptive real-time RF management. The Centralized wireless Solution uses Cisco’s patent-

pending Radio Resource Management (RRM) algorithms that detect and adapt to changes in the

air space in real-time. These adjustments create the optimal topology for wireless networking in

much the same way that routing protocols compute the best possible topology for IP networks.

Cisco RMM creates an intelligent RF control plane for self-configuration, self-healing, and self-

optimization of the wireless (Figure 10).

Specific intelligent RF capabilities managed by the Cisco Wireless LAN controller include:



Dynamic Channel Assignment—802.11 channels are adjusted to optimize network

coverage and performance based on changing RF conditions.



Interference Detection and Avoidance—The system detects interference and recalibrates

the network to avoid performance problems.



Load Balancing—The system provides automatic load balancing of users across multiple

access points for optimum network performance, even under heavy load.



Coverage Hole Detection and Correction—RMM software detects coverage holes and

attempts to correct them by adjusting the power output of access points.
