Product Overview

Main Features
  • 4400 Series WLAN Controller for up to 12 Cisco lightweight APs
Cisco® wireless LAN controllers are ideal for enterprise wireless LAN deployments and provide system-wide wireless LAN functions, such as security policies, intrusion prevention, RF management, quality of service (QoS), and mobility. They work in conjunction with Cisco 1000 Series lightweight access points and Cisco Wireless Control System (WCS) Software to support business-critical wireless applications. From voice and data services to location tracking, WLAN controllers provide the control, scalability, and reliability that IT managers need to build secure, enterprise-scale wireless networks-from branch offices to main campuses

Cisco wireless LAN controllers smoothly integrate into existing enterprise networks. They communicate with Cisco 1000 Series lightweight access points over any Layer 2 (Ethernet) or Layer 3 (IP) infrastructure using the Lightweight Access Point Protocol (LWAPP). This emerging IETF standard helps ensure that communication between access points and wireless LAN controllers remains secure, and it enables important wireless LAN configuration and management functions to be completely automated for cost-effective wireless LAN operations.

Cisco wireless LAN controllers enable enterprises to create and enforce policies for an end-to-end wireless LAN system that supports business-critical applications. Multiple WLAN Controllers automatically discover each other and seamlessly coordinate WLAN services across themselves. In this way, Cisco wireless LAN controllers work together as a single, seamless system to deliver a scalable WLAN network with thousands of APs. From voice and data services to location tracking, Cisco wireless LAN controllers provide the control, scalability, and reliability that IT managers need to build secure, enterprise-scale wireless networks.

The Cisco 4400 Series Wireless LAN Controller is designed for medium to large size facilities the 4402 with two Gigabit Ethernet ports comes in configurations that support 12, 25, and 50 access points. The 4402 provides one expansion slot that can be used to add enhanced functionality in the future, such as VPN termination and other capabilities. In addition, each 4400 WLAN Controller supports an optional redundant power supply to ensure maximum availability.

All Cisco WLAN controllers come equipped with embedded software for adaptive real-time RF management. The Cisco WLAN system uses patent-pending Radio Resource Management (RRM) algorithms that detect and adapt to changes in the air space in real-time. These adjustments create the optimal topology for wireless networking in much the same way that routing protocols compute the best possible topology for IP networks.
