Cisco Cisco Wireless LAN Controller Module

The Cisco wireless LAN (WLAN) controller module (WLCM) is designed to provide small and 
medium-sized businesses (SMBs) and enterprise branch office customers 802.11 wireless networking 
solutions for Cisco 2800 and Cisco 3800 series integrated services routers (ISRs) and Cisco 3700 series 
routers. The Cisco WLAN controller module enables Cisco ISRs and Cisco 3700 series routers to 
manage up to six WLAN access points (AP) and simplifies deploying and managing wireless LANs. The 
operating system manages all data client, communications, and system administration functions, 
performs Radio Resource Management (RRM) functions, manages system-wide mobility policies using 
the operating system security (OSS), and coordinates all security functions using the OSS framework. 
The Cisco WLAN controller module works in conjunction with Cisco Aironet lightweight access points, 
Cisco Wireless Control System (WCS), and the Cisco Wireless Location Appliance to support 
mission-critical wireless data, voice, and video applications.

The Cisco 2801 integrated services router does not support the Cisco WLAN controller module.
