The AIR-CT5520-K9 Cisco 5520 Wireless LAN Controller comes with a range of advanced wireless features that enable IT administrators to deploy and manage large-scale wireless networks with ease. Here are some of the advanced wireless features that the controller provides:

• RF Profiles: The controller allows you to create RF profiles to define radio settings and features, such as transmit power levels, channel width, and load balancing. RF profiles can be applied to individual access points or groups of access points to optimize wireless performance and improve network capacity.
• WLAN Groups: You can create WLAN groups to apply common settings and policies to multiple wireless networks. This feature simplifies the management of multiple wireless networks and helps to ensure consistent configuration across the network.
• FlexConnect: The FlexConnect feature enables access points to function in standalone mode when they lose connection to the controller. This feature is useful in branch office deployments and allows access points to continue providing wireless connectivity even when the connection to the controller is lost.
• Mesh Networking: The controller supports mesh networking, which enables access points to form wireless backhaul links with each other to extend wireless coverage without the need for wired connections. This feature is useful in outdoor deployments or areas where running cables is not practical.
• Adaptive wIPS: The controller provides an adaptive wireless intrusion prevention system (wIPS) that can detect and prevent unauthorized wireless access and attacks. This feature can help to ensure the security and integrity of wireless networks and prevent data breaches.
• ClientLink: ClientLink is a feature that improves the performance of wireless clients by optimizing the radio signal to match the client's capabilities. This feature can help to ensure that wireless clients receive the best possible performance and improve the user experience.

By providing advanced wireless features, the AIR-CT5520-K9 controller helps to simplify the management of wireless networks and improve their performance and reliability. IT administrators can use these features to optimize wireless performance, ensure network security, and provide a high-quality wireless experience to users.

The AIR-CT5520-K9 Cisco 5520 Wireless LAN Controller provides Quality of Service (QoS) and traffic management features that enable IT administrators to optimize wireless network performance, prioritize critical applications, and ensure a consistent user experience. Here are some key features:

• QoS policies: The controller can be configured to apply QoS policies to different types of traffic, such as voice, video, and data. These policies prioritize traffic based on its importance and ensure that critical applications receive the necessary bandwidth.
• Bandwidth management: The controller provides bandwidth management features that enable IT administrators to allocate bandwidth to different user groups, applications, and devices. This helps to prevent network congestion and ensure that critical applications have the necessary bandwidth.
• Load balancing: The controller provides load balancing features that help to distribute network traffic across multiple access points. This ensures that the network is evenly distributed and avoids congestion on individual access points.
• Application visibility and control: The controller provides application visibility and control features that allow IT administrators to monitor and manage application usage on the network. This enables administrators to identify and prioritize critical applications, and limit bandwidth usage of non-critical applications.
• Smart network analysis and optimization: The controller provides real-time analysis and optimization features that automatically adjust the network to provide optimal performance. This helps to ensure that the network is always operating at peak efficiency, and provides a consistent user experience.

By providing QoS and traffic management features, the AIR-CT5520-K9 controller helps to optimize wireless network performance, prioritize critical applications, and ensure a consistent user experience. IT administrators can use these features to manage and control network traffic, and ensure that wireless networks are optimized for efficient and reliable data delivery.
