Cisco 5520 IEEE 802.11ac Wireless LAN Controller - 2.40 GHz, 5 GHz - 2 x Network (RJ-45) - Ethernet, Fast Ethernet, Gigabit Ethernet - Rack-mountable AIR-CT5520-K9-RF

The Cisco 5520 Wireless Controller provides centralized control, management, and troubleshooting for high-scale deployments in service provider and large campus deployments. It offers flexibility to support multiple deployment modes in the same controller: for example, centralized mode for campus, Cisco FlexConnect™ mode for lean branches managed over the WAN, and mesh (bridge) mode for deployments where full Ethernet cabling is unavailable. As a component of the Cisco Unified Wireless Network, this controller provides real-time communications between Cisco Aironet® access points, the Cisco Prime™ Infrastructure, and the Cisco Mobility Services Engine, and is interoperable with other Cisco controllers.
