Simple and secure wireless deployment and management for small and medium-sized businesses (SMBs) and enterprise branch offices.

Product Overview

Cisco ® Wireless LAN Controller Modules (WLCMs), shown in Figure 1, 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.
Cisco is delivering higher scalability for the WLCMs. The modules manage 6, 12 or 25 Cisco Aironet ® lightweight access points and are supported on Cisco 2800, 2900 and 3800, 3900 Series Integrated Services Routers.

Cisco Wireless LAN Controllers

The Cisco WLCMs are models 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.
Because the Cisco Wireless LAN controller modules support 802.11a/b/g and the IEEE 802.11n draft 2.0 standard, organizations can deploy the solution that best meets their individual requirements. Organizations can offer robust coverage with 802.11 a/b/g or deliver unprecedented reliability using 802.11n and Cisco' Next-Generation Wireless Solutions.
