Cisco Unified Wireless Location-Based Services
Introduction
With integrated location tracking, enterprise wireless LANs become more valuable as a corporate
business asset. By identifying and tracking the location of wireless users, companies can improve the
accuracy of WLAN planning and deployment to optimize ongoing network performance, enhance
wireless security, and improve both the usefulness and value of important business applications.
Location tracking provides visibility and control of the RF environment, and helps IT staff deploy
wireless networks that are easier to manage and deploy.

This chapter discusses the location-aware Cisco Unified Wireless Network (UWN). It focuses primarily
on design considerations but mentions topics meriting special consideration during deployment as well.
These areas are described in brief and references are made to a comprehensive white paper entitled Wi-Fi
Location-Based Services: Design and Deployment Considerations, which contains in-depth discussion
and analysis. This white paper is available at the following URL:
