Product Description

This is the eBook version of the printed book.The Definitive Guide to WiMAX Technology
WiMAX is the most promising new technology for broadband wireless access to IP services. It can serve an extraordinary range of applications and environments: data, voice, and multimedia; fixed and mobile; licensed and unlicensed. However, until now, wireless professionals have had little reliable information to guide them. Fundamentals of WiMAX is the first comprehensive guide to WiMAX-its technical foundations, features, and performance.

Three leading wireless experts systematically cut through the hype surrounding WiMAX and illuminate the realities. They combine complete information for wireless professionals and basic, accessible knowledge for non-experts. Professionals will especially appreciate their detailed discussion of the performance of WiMAX based on comprehensive link- and system-level simulations.

Whether you're a wireless engineer, network architect, manager, or system designer, this book delivers essential information for succeeding with WiMAX-from planning through deployment.

Topics include

• Applications, history, spectrum options, technical and business challenges, and competitive technologies of WiMAX

• 802.16 standards: physical and MAC layers, channel access, scheduling services, mobility, advanced antenna features, hybrid-ARQ, and more

• Broadband wireless channels: pathloss, shadowing, cellular systems, sectoring, and fading-including modeling and mitigation

• OFDM: from basic multicarrier concepts to synchronization, PAR reduction, and clipping

• MIMO: Multiple antennas, spatial diversity, beamforming, and a cutting-edge treatment of the use of MIMO in WiMAX

• OFDMA: multiple access, multiuser diversity, adaptive modulation, and resource allocation

• Networking and services aspects: architecture and protocols for IP QoS, session management, ecurity, and mobility management

• Predicting performance using link-level and system-level simulations

• WiMAX network architecture: design principles, reference models, authentication, QoS, and mobility management

2.0 out of 5 stars Erros and lack of details make this a poor engineering reference, August 17, 2007

By	Feng Mo "citi customer" (TX USA) - See all my reviews (REAL NAME)

I was looking for a book on WiMax as a reference for designing WiMax radios. Trying to understand WiMax by reading the IEEE 802.16, 16e standards is difficult. The original 802.16-2004 standard was organized in a convoluted way. On top of that there were numerous errors, even in the mathematical formula and the critical system parameters. 16e was written as a errata and addendum to .16. Given the amount of major changes required by .16e, this format of a .16+.16e makes it almost impossible to read to gain engineering understanding. I was looking for a book that could untangle this mess and present the information in .16+.16e in a linear and logical way, if not the MAC, at least the PHYs. The Andrews book does not serve this purpose. Most of the technical details of the WiMax system are missing. For example, a WiMax radio starts with transmitting or receiving the preambles. There are hundreds of preambles in WiMax. I would expect the book to describe all these preambles for reference. It would be even better, if there are insights into the mathematical properties of these preambles for the receiver design. If you agree with my statement, just let me say that the Andrews book contains none of the details the preambles beyond saying WiMax has something called preamble. Of the limited amount of PHY details the book did contain, there are critical errors. For example, the book seems to suggest that the downlink PUSC subchannels consist of two chunks of contiguous OFDM subcarriers of 14 each. According to the 802.16/16e, the 28 subcarriers in a subchannel are scattered. For the lack of details, I feel this book serves poorly as an engineering design reference. It also serves poorly as a guide to untangle the material in IEE802.16/16e due to the lack of details and the critical errors.

4.0 out of 5 stars an engineer's book, May 15, 2007

By	W Boudville (Terra, Sol 3) - See all my reviews (TOP 10 REVIEWER)    (REAL NAME)

Andrews suggests in the Preface that the book will be suited to a wide range of people who want to learn about WiMax. From engineers to graduate students to managers and executives and others. Indeed, there are high level descriptions, scattered throughout the chapters, accessible to those without an engineering degree. But typically, these are introductory summary remarks. The bulk of every chapter is really best understood if you have that engineering background. While the author naturally desires as wide an audience as possible, this is really an engineer's book.

The overviews do show that WiMax exhibits strong advantages over the current and popular WiFi. Like having robust security protocols, including the Advanced Encryption Standard (aka Rijndael) and 3DES. Plus WiMax has terminals that possess built-in digital certificates with public and private keys and MAC addresses. Contrast this with WiFi, whose commonly used Wireless Encryption Protocol has some severe deficiencies.

Another important advantage of WiMax is how it supports extreme mobility modalities. Where you, the end user, can travel in a vehicle up to 120 kmph, and have seamless handoff between WiMax basestations.

Many chapters are highly mathematical. Indeed, one chapter on multi-antennas reads like an excursion into advanced linear algebra or matrix theory. It even evokes the Frobenius norm of a matrix, which I'd only ever seen before in a pure maths course.

Of all the chapters, maybe that which discusses Mobile IP could be the most interesting. It takes the Internet as we know it, and removes a serious current limitation to moving your machine, and having it keep connected to the Internet. Mobile IP is a cunning overlay on IPv4. While it can also be done, and much easier, in IPv6. The only problem is when the latter will start to dominate v4.

Overall, the book is a very promising pitch for WiMax deployment.

4.0 out of 5 stars $69.99 buys you depth, May 28, 2007

By	jose.r-s (Seattle, WA, USA) - See all my reviews

As of May 28 2007, if you are going to fork some money onto a WiMax book, this book should be it. The authors were smart to concentrate in explaining the technology building blocks of the standard instead of just following the structure of the 802.16 document. I have read mostly the chapters related to the PHY and I found the explanations and examples clear and to the point. Even if you are not interested in the WiMax standard per se, this book contains very good information about OFDM/OFDMA and multi-antenna techniques for broadband wireless systems. It also has a couple of chapters about link level and system level performance of WiMax that add even more depth to the book.
