Designing and Deploying 802.11n Wireless Networks (eBook)

As the final 802.11n wireless LAN standard is ratified, thousands of companies are beginning to plan their deployments, many are already moving forward based on the stable Draft 2 standard. However, 802.11n is very different from legacy 802.11a, 802.11b and 802.11g wireless standards, and deployment requires new knowledge and techniques. In this book, leading wireless expert Jim Geier systematically presents all the information and guidance enterprise IT professionals and managers need to deploy 802.11n successfully and achieve maximum performance and business value. Drawing on his extensive experience with real-world 802.11n deployments, Geier covers the entire project lifecycle: planning, design, installation, testing, and support. He offers practical, how-to guidance for deploying in enterprises without existing wireless infrastructure, as well as migrating from legacy 802.11x wireless networks. Part I of this book focuses on the underlying concepts that must be understood before deploying an 802.11n wireless network. Part II focuses on the latest 802.11 standard itself, including current medium access and physical layers, 802.11n functionality, and other current updates, such as 802.11r.

Gain a practical understanding of the underlying concepts of the 802.11n standard and the methodologies for completing a successful wireless network installation Practical, start-to-finish guidance for successful deployment of 802.11n wireless LANs With the ratification of the 802.11n wireless LAN standard, thousands of companies are moving rapidly toward implementation. However, 802.11n is very different from legacy 802.11a, 802.11b, and 802.11g wireless standards, and successful deployment requires new knowledge and techniques. In this book, leading wireless expert Jim Geier systematically presents all the information and guidance that network architects, engineers, administrators, and managers need to maximize the performance and business value of new 802.11n networks. Drawing on extensive experience with real-world 802.11n deployments, Geier guides you through the entire project lifecycle: planning, design, installation, testing, monitoring, and support. Each phase of wireless LAN deployment is organized into clearly defined steps, and multiple case studies and hands-on exercises show how to apply each technique. You'll find practical guidance for deploying in enterprises without existing wireless infrastructure, as well as migrating from legacy 802.11a, 802.11b, or 802.11g networks. For convenient reference, Geier also provides an extensive, up-to-date wireless networking glossary.
