The ZyXEL NXC-8160 Wireless LAN Controller is the central component of ZyXEL's unique "Interference-Free" architecture, while the NWA-8500 802.11a/g Ultra-thin Wireless Business Access Point is a high-performance dual 802.11a/b/g Wireless Access Point that interoperates with NXC-8160.
The unique solution enables the signals on the same channel to be transmitted through every access point in the system without the co-channel interference that plagues other WLAN solutions. Clients only need to associate with the controller once in order to move within the channel blanket without experiencing inter-AP handoffs. As a result, different WLAN security settings will have no impact on its speed; that is, the zero-delay roaming functionalities can retain its outstanding "always-connected" performance even with the most sophisticated encryption and authentication mechanisms applied.
Simply put, the solution provides the flexibility, performance and simplicity required by enterprises to support data, video and voice (VoWLAN) applications in ubiquitous WLAN deployments. The 8-port controller can be used individually or in combination with multiple controllers to meet the needs of crowded enterprise environments of any size or kind.
