A wireless LAN controller (WLC) is a network device used to manage wireless access points in a computer network. WLCs are connected to routers and allow devices from across the organization to connect to the router via access points. WLCs are generally used in combination with the Lightweight Access Point Protocol (LWAPP) to manage light-weight access points in bulk by the network administrator or network operations center. The wireless LAN controller is part of the Data Plane within the Cisco Wireless Model.

The WLAN controller automatically handles the configuration of wireless access points. It centralizes wireless network infrastructure and handles bandwidth allocation to the access points (APs). Before the use of WLCs were widespread, APs had to handle connections individually, leading to unstable data links and poor connections. The use of WLCs solves this problem.

Benefits of WLCs

The benefits of using WLCs are as follows:

• WLCs allow for centralized AP deployment and management, simplifying network maintenance operations.
• WLCs add an additional layer of security to the network by providing central web authentication, firewall integration, and detection of rogue APs.
• WLCs allow clients to move between APs (a behavior termed as user roaming), allowing uninterrupted service.
