Cisco 5520 Controller Key Attributes - Cisco 5520 Deployment Manual

and the adoption of Wi-Fi in service provider networks enabling new business models require wireless networks to provide larger
AP scale, client scale, and higher throughput.
The Cisco Unified Wireless Network Software Release 8.1 addresses these key challenges. Release 8.1 delivers the new Cisco 5520
wireless controller with support for 20 Gbps throughput, 1500 APs, and 20,000 clients to ensure better performance and scale for
business critical networks.
The following table captures some of the key hardware capabilities of this new platform.
