The Cisco 2106 Wireless LAN Controller is a model in the Cisco Wireless LAN Controller family which includes standalone controllers, integrated controllers, and modular wireless LAN controllers that work in conjunction with Cisco switches and routers.

Cisco Wireless LAN controllers are ideal for small, mid-sized, enterprise business and service provider wireless LAN deployments and provide system-wide wireless LAN functions, such as security policies, intrusion prevention, RF management, quality of service (QoS), and mobility. They work in conjunction with Cisco lightweight access points and Cisco Wireless Control System (WCS) Software to support business-critical wireless applications. From voice and guest access services to location tracking, WLAN controllers provide the control, scalability, and reliability that IT managers need to build secure, enterprise-scale wireless networks-from branch offices to outdoor campuses.
