Controller-Based Wireless LAN Fundamentals: An end-to-end reference guide to design, deploy, manage, and secure 802.11 wireless networks

Introduction

Since the first Cisco Press book on the fundamentals of 802.11 networks, much has changed. Wireless local-area networks (WLAN) have grown dramatically in size and scope, creating changes for traditional wireless deployment architectures. Many of the challenges with prior generations of wireless networking designs have been greatly reduced with development of the Cisco Wireless Unified Network (CUWN) architecture. The Cisco Unified approach has allowed wireless networks to efficiently scale to meet new requirements and business needs. WLAN controllers rapidly became the dominant wireless architecture and have been standardized through the IETF Control and Provisioning of Wireless Access Points (CAPWAP) protocol. CAPWAP defines an ...
