1: WiMAX Expert
I think this book gives you a little bit more that just the fundamentals of WiMax. You should read this book only if you have a decent understadings in communication theory because. If you do the topics covered in this book will make a lot more sense, otherwise you will be struggling with a lot of the concepts and acronyms.

2: WiMAX from a test users
Enjoyed the earlier chapters and how they introduced the later chapters which went into greater detail on each topic. The detailed chapters included equations, tradeoffs and examples.

3: Extensive coverage of WiMAX standards
This is an excellent starter book on WiMAX. The most useful aspect of this book is the extensive coverage of IEEE 802.16e (mobile WiMAX) PHY and MAC standards. Another very useful feature is the listing of typical system configurations used in real deployments of WiMAX. The technical chapters on OFDM, OFDMA, and space-time coding are also useful but can be found in other texts.

4: Erros and lack of details make this a poor engineering reference
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.

5: $69.99 buys you depth
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.
