Introduction to 3G Mobile Communications, Second Edition Review

Introduction to 3G Mobile Communications, Second Edition
Average Reviews:

(More customer reviews)
This book is a systematic look at 3G's component parts and underlying technologies. It is not an engineering text in that there are no formulae or engineering details with respect to signalling, capacity or performance (even though network planning considerations are addressed).
It dissects 3G, starting with principles to provide an anchor.
The table of contents shows the progression in which the author deals with 3G as a collection of components, principles and protocols: Principles of Division Multiple Access, WCDMA Air Interface: Physical Layer, Modulation Techniques and Spread Spectrum, Spreading Codes, Channel Coding, WCDMA Air Interface: Protocol Stack. Network, Network Planning, Network Management, Procedures, New Concepts in the UMTS Network, 3G Services, and 3G Applications.
Because of the technical nature of this book and the level of detail given, it's best suited for readers who are familiar with the technical underpinnings of TDMA, CDMA or GSM. The writing is clear and augmented by numerous illustrations, and each chapter ends with a list of references. The references are a strong point about this book because they are up-to-date and include books, papers and URLs.
If you are looking for engineering details this is the wrong book. If you have a background in related technologies and want to quickly get up-to-speed in 3G this is an excellent resource.

WCDMA Design Handbook Review

WCDMA Design Handbook
Average Reviews:

(More customer reviews)
Prior to the review, i would like to mention that i have over 6 years of experience in Wireless core network Product validation in GSM/UMTS; also i had read another book "UMTS" by "Javier Sanchez" & "Mamadou Thioune". Therefore i had a fair handle on the architecture and aspects of UMTS access, but my understanding was lacking a solid grounding.
I picked up this book and started reading, and it was like all the missing pieces were found, and my understanding stood on a more solid ground. To give a few examples,the coverage of the following things in the second chapte,were pivotal in plugging the gaps in my understanding.
- how to differtiate a UE in uplink as well as downlink
- principles of WCDMA physical layer - channelization & scrambling codes,soft handover,use of compressed mode & power management. These are known by any person who has a "more than casual" study of the UMTS access, but they were clearly marked as differtiators.
- Radio and data connections
- UMTS security architecture etc
What clinches the deal for me is Chapter 3 with its clear explanations of single user spreading code use, multi-user spreading code use(to mention a few) with clear diagrammatic illustrations.
The author has distilled years of experience in this book; any user who is suffciently experieced in wireless networks can pick this book up and glide across from beginning to end
This book caters to R99 UMTS networks;the only thing i wish this book had was the coverage of newer technologies - HSDPA, HSUPA and LTE.

I bought this book sometime ago because I thought that the author's previous book was well written, however I never found time to read it thoroughly.
Over past few months, I discovered that I kept going back to the book and the author's blog to look for reference (e.g. to get a better understanding on SIM card, or to calculate spectrum efficiency and cell capacity, etc.). So I decided to bring this book with me on a trip and finally read the whole book (well... almost). I have to say this is another very well written book from the author. The writing is very clear and the figures show up at where they are needed, nothing fancy, dry, or redundant. Just enough text and figures to cover the topic and I never had to re-read a section to understand the subject (like I usually do when reading a 3GPP standard).
What I liked the most about this book is that the selected areas that the author chose to dive into reflected not only his thorough understanding of the standard, but also his obvious hands-on experience. This book was not only well comprehensible, but also practical, an excellent reference to have at your desk for a wireless engineer. I look forward to read future publications from the author, either at his blog or a new book.

Fundamentals of LTE (Prentice Hall Communications Engineering and Emerging Technologies Series) Review

Fundamentals of LTE (Prentice Hall Communications Engineering and Emerging Technologies Series)
Average Reviews:

(More customer reviews)
I am an RF Engineer, tasked with optimizing the radio link between the phone and the tower (or in LTE terminology, the User Equipment and e-Node B). Admittedly, this is the first BOOK about LTE I have read. Without other perspective, I give it a 3 star rating because of how useful it will be to me in my role. This is a great reference text for LTE--detailed as it is--on the background considerations and ALL the possibilities and thought that went into the LTE standard, but it's really over my head! It has little information, probably quite understandably, about vendor implementation and how to solve practical issues. What I needed to learn from the book could be reduced to 50 pages instead of 383, that's why I'll keep it on my shelf as a reference text, just in case. But otherwise I've taken extensive notes, which is really all I need.
The author(s) is a good teacher; he keeps re-expressing relevant points previously covered at the appropriate time in each lesson, and gives good summaries at the end of each chapter. The book is thoroughly indexed, and the text of each chapter points the reader to where other matters are more fully explained in other chapters/sections. Though it has a very useful list of acronyms, about 10 important acronyms are not on the list (an oversight by the editors). But the book could really benefit (I could really benefit) from also having a glossary, it would be worth extending the page count to 400. I suggest others on my level take advantage of the authors pedagogical style and the book's index in the following manner: start with the summary at the end of each chapter and if you see something you want to dig into, then go into the chapter for more details or use the index to find the actual lesson. By this means you can extract the most information with the least investment of time. Not all books are written well enough to use (or trust) this method to cover the material. This one is.

The Definitive Guide to LTE Technology
Long-Term Evolution (LTE) is the next step in the GSM evolutionary path beyond 3G technology, and it is strongly positioned to be the dominant global standard for 4G cellular networks. LTE also represents the first generation of cellular networks to be based on a flat IP architecture and is designed to seamlessly support a variety of different services, such as broadband data, voice, and multicast video. Its design incorporates many of the key innovations of digital communication, such as MIMO (multiple input multiple output) and OFDMA (orthogonal frequency division multiple access), that mandate new skills to plan, build, and deploy an LTE network.

In Fundamentals of LTE, four leading experts from academia and industry explain the technical foundations of LTE in a tutorial style— providing a comprehensive overview of the standards. Following the same approach that made their recent Fundamentals of WiMAX successful, the authors offer a complete framework for understanding and evaluating LTE.

Topics include

Cellular wireless history and evolution: Technical advances, market drivers, and foundational networking and communications technologies
Multicarrier modulation theory and practice: OFDM system design, peak-to-average power ratios, and SC-FDE solutions
Frequency Domain Multiple Access: OFDMA downlinks, SC-FDMA uplinks, resource allocation, and LTE-specific implementation
Multiple antenna techniques and tradeoffs: spatial diversity, interference cancellation, spatial multiplexing, and multiuser/networked MIMO
LTE standard overview: air interface protocol, channel structure, and physical layers
Downlink and uplink transport channel processing: channel encoding, modulation mapping, Hybrid ARQ, multi-antenna processing, and more
Physical/MAC layer procedures and scheduling: channel-aware scheduling, closed/open-loop multi-antenna processing, and more
Packet flow, radio resource, and mobility management: RLC, PDCP, RRM, and LTE radio access network mobility/handoff procedures

3G Evolution, Second Edition: HSPA and LTE for Mobile Broadband Review

3G Evolution, Second Edition: HSPA and LTE for Mobile Broadband
Average Reviews:

(More customer reviews)
As an implementation engineer, I needed to understand in detail each and every aspect of LTE specification. My job is to design the network stack of LTE (both base station and mobile station). When I started reading 3GPP LTE specification(36 series) 4 months ago, I found several sore concepts sticking out. Then I read the first edition of this book and found several concepts cleared. However the first edition had very few pages on LTE and focused more on WCDMA.
Then came this edition. I ordered this book from Amazon and it came within 2 weeks. This book makes understanding of LTE very easy. For instance I had several doubts in the RLC spec of 3gpp. Then I read the RLC content of this book and got all my doubts cleared.
The best thing about this book is that unlike other books, the contents of this book are not directly picked up from specification. It seems the authors of the book have a good grasp of what they are writing and have spent enough time to make it easy to read. Language is very succint. Each line makes sense, is relevant and helps increase understanding of LTE.
Overall this is probably the best book for LTE(and I have read several books). The book has been written in a fluid way and the flow of thought is connected. I have still not read the book completely, but I find myself going to the book again and again(in my free time or bedtime) just because it is a pleasant read.
Cons: At $120 I could not buy the book myself and had to ask my employer to purchase it. I wish they reasonably price it so that I can get a personal copy(and be able to underline several important things).

(More customer reviews)
Its a pretty good book for those who are new to wireless and even those who'd like to learn more. It covers 1G, 2G, 2.5G and 3G wireless networks and various air interfaces used and/or are proposed for these networks. It gets over the ambiguities of various 3GPP releases and clearly describes each release (99, 2000-4, and 2000-5) and their associated network reference model. There is also plenty of good description on various 2G radio access standards (AMPS, TMDA, CDMA, GSM, WCDMA, CDMA2000) and their associated network reference models. While it doesn't have in-depth coverage of any particular wireless topic, it attempts to give a broad overview on everything wireless and provides plenty of references for readers to follow up.
