Cisco 5520 Wireless LAN Controller Deployment Guide

Introduction

This document introduces the Cisco 5520 Wireless LAN Controller (WLC), and provides general guidelines for its deployment. The

purpose of this document is to:

•Provide an overview of the Cisco 5520 WLC, and its deployment within the Cisco Unified Architecture.

•Highlight key service provider features.

•Provide design recommendations and considerations specific to the Cisco 5520 Controller.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

This document is not restricted to specific software and hardware versions.

The information in this document is created from the devices in a specific lab environment. All of the devices used in this document

started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any

command.

Product Overview

The existing Cisco 5500 series controller scales up to 500 APs, 7,000 clients, and 8 Gbps maximum throughput. The explosion of

mobile clients in enterprise empowered by bring your own device (BYOD), the deployment of wireless in mission-critical applications,

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.
