Cisco 2100 Series Wireless LAN Controllers

This product has been retired. Please contact sales to discuss replacement products.

The Cisco® Wireless LAN Controllers work in conjunction with Cisco access points and the Cisco Wireless Control System (WCS) to provide systemwide wireless LAN functions. As a component of the Cisco Unified Wireless Network, the Cisco 2106 Wireless LAN Controller presents network administrators with the visibility and control necessary to effectively and securely manage business-class WLANs and mobility services, such as voice, guest access, and location services.

Because the Cisco Wireless LAN Controllers 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 greater performance with 5x the throughput and unprecedented reliability using 802.11n and Cisco’s Next-Generation Wireless Solutions and Cisco Enterprise Wireless Mesh.

The Cisco 2106 Wireless LAN Controller (Figure 1) supports up to six lightweight access points, making it a cost-effective solution for multi-controller architectures typical of enterprise branch deployments. It may also be used for single controller deployments for small and medium-sized business environments. The Cisco 2106 Wireless LAN Controller provides eight Ethernet ports, two of which can provide power directly to Cisco lightweight access points.
