Cisco Wireless LAN Controllers are responsible for 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 1000 Series Lightweight Access Points and the Cisco Wireless Control System (WCS) to support business-critical wireless applications. From voice and data services to location tracking, Cisco Wireless LAN Controllers provide the control, scalability, security, and reliability that network managers need to build secure, enterprise-scale wireless networks—from branch offices to main campuses.

Cisco Wireless LAN Controllers smoothly integrate into existing enterprise networks. They communicate with Cisco 1000 Series Lightweight Access Points over any Layer 2 (Ethernet) or Layer 3 (IP) infrastructure using the Lightweight Access Point Protocol (LWAPP). These devices support automation of numerous WLAN configuration and management functions across all enterprise locations.

The Cisco 4100 Series Wireless LAN Controller is designed for medium-to-large enterprise facilities. Models that support 12, 24 or 36 access points are available. It also offers dual Gigabit Ethernet uplinks for high speed LAN connectivity with high network availability.
