5.0 out of 5 stars
Superb account of LTE, January 13, 2010
This review is from: LTE and the Evolution to 4G Wireless: Design and Measurement Challenges (Hardcover)
This book is an extremely well written account of LTE, with the emphasis on the design and implementation of the air interface physical layer.
Chapters 1 to 5 give the reader a clear, concise account of the 3GPP specifications for LTE. Unusually for a telecommunications book, the material is extremely well written and easy to read, indicating a lot of care by the editor and authors. The information is quite densely packed and really requires previous knowledge of 3G, but is probably the most effective account of LTE that I have so far read.
My one suggestion for improvement lies in chapters 4 and 5, where I would have appreciated some use cases to illustrate how the different procedures and network elements interact. But this is not an important issue, and does not affect my overall rating.
The book really comes in to its own in chapters 6 and 7, which cover material relevant to design and implementation that lies outside the scope of the specifications. Especially valuable was a 60 page account of the characterisation and measurement of the transmitter and receiver, reinforced by signal analyser plots that illustrate what the main signal impairments actually look like. A concluding chapter describes the enhancements that are being made in LTE-Advanced, to meet the ITU's requirements for 4G.
Because of the material in chapters 6 and 7, this book will be especially valuable to those who are working on the lower parts of the LTE physical layer. However I would wholeheartedly recommend it to anyone who requires a clearly written introduction to LTE.

5.0 out of 5 stars
Very clear explanation of LTE, January 21, 2011
This review is from: LTE and the Evolution to 4G Wireless: Design and Measurement Challenges (Hardcover)
I'm a radio frequency engineer, tasked with design and optimization of the link between the phones and the towers. This book is exactly what I needed to understand LTE. I highly recommend it to others who might have the same need. The only suggestion I would make is for a chapter describing the limitations of LTE, like for example:
- that no one is doing voice on it yet, why not?, and how will it handle e911 calls?
- problems with the backhaul;
- problems of creating eNodeB's (who is really going to pay for X2 links between every tower and its neighbors? Not likely to happen in my opinion, so maybe the eNodeB implementations won't be all that different from the standard BSC);
- how to handle frequency planning (subband segmentation) and capacity at the network edges;
- how to optimize handoffs;
- problems with MIMO deployment (cannot put 4 more antenna per sector on most towers--failed structurals--in addition to existing networks' antennas, which won't be going away anytime soon, maybe dualpole antennas, so what benefits can be realized under these circumstances?)
- some info about vendors' implementations if possible
But despite my remaining questions, the information that was in this book is pretty clearly explained. It is after all intended for a different audience, the component design engineers working on the board level to build and certify the system.
