Fundamentals of WiMAX: Understanding Broadband Wireless Networking ReviewI 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.Fundamentals of WiMAX: Understanding Broadband Wireless Networking Overview
