Wireless LAN Controllers Improve Visibility and Control

Wireless LAN (WLAN) controllers simplify the deployment and operation of wireless networks, helping to ensure smooth performance, enhanced security, and maximum network availability.

Cisco WLAN controllers communicate with Cisco Aironet access points over any Layer 2 or Layer 3 infrastructure. They support system-wide functions that include:

• Enhanced security with WLAN policy monitoring and intrusion detection
• Intelligent radio frequency (RF) management
• Centralized management
• Quality of service (QoS)
• Mobility services, such as guest access, voice over Wi-Fi, and location services

From voice and data services to location tracking, Cisco WLAN controllers provide the control, scalability, security, and reliability you need to build highly secure, enterprise-scale wireless networks.
