Cisco's standalone, integrated or modular wireless WLAN controllers ensure smooth performance, enhanced security, and maximum network availability. Integrate existing enterprise networks for advanced management capabilities and performance; these devices communicate with Cisco Aironet LAPs (lightweight access points) over any Layer 2 (Ethernet) or Layer 3 (IP) infrastructure and are responsible for handling functions throughout the system. New surplus Cisco Aironet WLAN controller devices are available through MULTI-LINK and we encourage you to contact us to find out how much you can save with a pre-owned WLAN Controller.
