Item description for WiMax Explained; System Fundamentals by Lawrence Harte...
This book explains the functional parts of a WiMax system and its basic operation. You will learn how WiMax can use base stations to provide high speed data connections that can be used for voice, data and video services to distances of over 30 km. The original WiMax system was designed to operate at 10-66 GHz and it had to change to offer broadband wireless access (BWA) in the 2-11 GHz frequency range. To do this, the WiMax standard includes variants (profiles) that use different combinations of radio channel types (single carrier -vs- multicarrier), modulation types, channel coding types to provide fixed, nomadic or portable services. WiMax can provide multiple types of services to the same user with different QoS levels. For example, it is possible to install a single WiMax transceiver in an office building and provide real time telephone services and best effort Internet browsing services on the same WiMax connection. To do this, WiMax was designed to mix contention based (competitive access) and contention free (polled access) to provide services which have different quality of service (QoS) levels. You will learn about WiMax protocols and how they are designed to allow for point to point (PTP), point to multipoint (PMP) and mesh networks. Operators can use the mesh configuration to allow it to link base stations without the need to install or lease interconnecting communication lines. Some of the services WiMax operators can provide include leased line, residential broadband, commercial broadband and digital television (IPTV) services. WiMax can use radio channel bandwidths that can vary from 1.25 MHz to 28 MHz and data transmission rates can exceed 155 Mbps. The types of data connections on WiMax radio channels include basic (physical connection), primary (device control), secondary (configuration) and transport (user data). You will learn about the typical range for WIMAX systems and how to extend the range of WIMAX systems through the use of directional antennas. Some of the most important topics featured include: . The Functional Parts of WiMax Systems . Basic WiMax Operation . The Types of WIMAX Services . Data Transmission Rates . WIMAX Industry Standards . WIMAX Technology Evolution . Protocols Used in WiMax . Physical and Logical Channel Types . The Different Types of WIMAX Devices . Basic Security Operation

Dont Publish a Book that has not been Edited for Typos and Grammatical Errors Jul 7, 2008
One would think that if someone bothered to publish a book, they could at least hire a student to read it through and correct basic typos and grade school level grammatical errors. These are on almost every page. This is pathetic!
Apart from that, for a 10,000 foot level overview of the technology, this book does the job. Having now read it, I would not buy it given another choice, as it does not provide enough technical detail, and does not tie the various parts of the technology discussion together sufficiently.
WiMax explained well at the system level Jan 22, 2008
This book is a good explanation of WiMax for a technical person new to the technology that appreciates a clear and crisp description of a broad set of technical WiMax topics, or for a non-technical person needing to understand the WiMax technology to a good level of detail after a quick read. I would not recommend it for someone looking for WiMax specifications in detail for protocol, circuit or product design (I would suggest going to the IEEE specification for that or email me for recommendations). But for anyone becoming involved in WiMax, particularly at a system, networking, deployment, or operations level, this book provides good solid information. The illustrations I found to be good for this level, and the information is timely. I am happy with my purchase and at this price it has met my current needs and expectations.
Excellent. Starts with what you know and builds technically. Oct 21, 2007
I needed to get up to speed on WiMax and quick. I bought a few books but this one was clearly the best. It's a straight forward "explaination" of WiMax starting with "What is WiMax" to Service Flows.
It starts with technical information that I already understood and clearly added/combined/modified technical details to develop a logical and technical explaination of what WiMax. It's at the right technical level. It stops short of all the protocol details (however many of those are existing and I know them) that bogs down a lot of technical books. There's nothing worse than pay $50 for a book and getting 20 pages of overview and then 150 of standards which I could have gotten for free online.
This book definately gave me the right technical information sprinkled with illustrations that were SIMPLE to understand. The figures are clear and relate directly to the explainations. It saved me a lot of time by getting me up to speed quick so I now have a good understanding of the WiMax system.
One more praise for this book...The index is really well done. I'm not sure what it is, but when referring back to this book for information when I'm working, I find it easily in the index. They must be doing something right. Most technical books have me just flipping through the book to find information becuase the index doesn't help get you to the specific item you need.
Painfully basic and filled with grammatical errors Oct 16, 2007
This book is written as if for someone that has no communications experience and is filled with grammatical errors. It appears it has not been proof read. The figures are almost laughable and of little to no use. Save your money, perform a one minute google search and you will be $15.00 ahead.
