With market value expected to reach $5 billion by 2007 and the endorsement of some of the biggest names in telecommunications, World Interoperability for Microwave Access (WiMAX) is poised to change the broadband wireless landscape. But how much of WiMAX's touted potential is merely hype? Now that several pre-WiMAX networks have been deployed, what are the operators saying about QoS and ROI? How and when will device manufacturers integrate WiMAX into their products? What is the business case for using WiMAX rather than any number of other established wireless alternatives? WiMAX: Taking Wireless to the MAX examines the evolution of wireless, broadband, and the wireless broadband landscape with exhaustive coverage of technological advances and evolving topologies. It sets the tone for the journey towards untouched wireless heights - WiMAX. The author builds a complete understanding of Broadband Wireless Access (BWA) Technologies, elaborating on past developments, present needs and uses, and future trends and markets. He lays out a road map to the future and articulates present and future applications and models of BWA with focus on WiMAX. The book also provides a detailed discussion on the advanced technologies central to the existence of WiMAX. It presents strategies for building the case for WiMAX and achieving success for the different players, including service providers and equipment manufacturers.

Author(s) Doug Lowe
ISBN 0470056207
Release Date 29 May 2007

Networking for Dummies upholds the series' proletarian tradition by entertainingly explaining local area networks (LAN) to the rest of us. Written with three different-but equally "clueless in technical matters;quot;-audiences in mind, Lowe's book appeals to novice network users, novice network builder/administrators, and the managers who must finance the activities of the other two groups.

A large part of this book is devoted to user issues such as "Accessing a network drive from WordPerfect" and "What is a print job?" Other chapters explain the differences among the various network architectures and network operating systems. In addition, the book pays a lot of attention to troubleshooting, particularly for common problems.

For these reasons, Networking for Dummies makes a fine resource for people who are new to a networked environment. If you are a network administrator, you might want to get a copy (or three) of this book for the corporate library and refer it to all askers of brain-dead questions.

The book's primary shortcoming is its ignorance of Microsoft Windows NT 4.0 and Novell IntranetWare. (Coverage of NT stops at version 3.51 and coverage of NetWare stops at version 4.1.) Still, lots of organizations still run these network operating systems, and if yours is one of them, this book may fit your needs admirably.

You generally can't pick up knowledge of Cisco products casually, the way you can learn about Microsoft Windows, Unix, and other products that are more generally accessible. For this reason, Cisco: A Beginner's Guide performs a valuable service. It introduces internetworking novices to the language and fact base that underlie routers, switches, network protocols, and the rest of the Internet's infrastructure. True enough, no book can teach you everything you need to know about a subject as complex as internetworking, but this one does a great job of giving you the background you need to perform well in a class or do hands-on experiments intelligently.

The book goes heavy on prose, enabling you to slowly absorb the truth about complex systems as the author lays a foundation of knowledge and then builds upon it. Conceptual diagrams help drive home relationships among network devices, though the blueprints in the center of the book suffer from being split down the middle by the book's binding-foldouts would have been far better. This is a superb book, though, one of the best around on internetworking with Cisco. It would make an excellent first purchase for a future Cisco expert or a fine "fundamentals" reference for more accomplished network engineers. -David Wall

Topics covered: Internetworking from a theoretical standpoint, backed up by information on how Cisco products handle implementation (meaning, in part, that you get information on which Cisco lines and models are good for which jobs). Technically, readers get the goods on Cisco Internetwork Operating System (IOS), routers, switches, routing protocols, and security. There's great information on the pantheon of Cisco certifications too.
