Executive Summary

This paper revisits the benefits of centralized 802.11n wireless LAN networks and describes the case for transforming the controller-based architecture to match market needs. Centralization of Wireless LANs (WLANs) delivers networks that are easy to deploy, scale, and manage. A local-mode controller-based campus environment delivers increased device scalability and an interactive multimedia experience coupled with enhanced policy to manage the full range of mobile devices. A controller-based deployment using FlexConnect technology enables multisite, lean branches to manage the increased scale of deployments without additional increase in operational complexity.
