Cisco Wireless LAN Controller Modules (WLCMs) supported on the Cisco Integrated Services Routers (ISR), provide an easy to deploy, cost-effective branch office or small to medium business wireless solution. As a component of the Cisco Unified Wireless Network, the Cisco WLCMs give network administrators the visibility and control necessary to effectively and securely manage business-class wireless LANs and mobility services, such as enhanced security, voice, guest access, and context aware mobility or location services. WLCMs work in conjunction with Cisco lightweight access points and the Cisco Wireless Control System (WCS) to provide centralized wireless LAN management and monitoring.
