LTE for UMTS - OFDMA and SC-FDMA Based Radio Access Review

LTE for UMTS - OFDMA and SC-FDMA Based Radio Access
Average Reviews:

(More customer reviews)
LTE is the next evolution of wireless communications. I have to state at the outset that as a former COO of NYNEX Mobile and one of the proponents of CDMA in the 1980s, I find that LTE is merely a natural progression of what was started almost a quarter century ago. LTE does not deliver any major technical advances, it implements them. OFDM has been around for almost fifty years in some form as has been the MIMO antenna configuration. LTE is the natural progression to an all IP fabric, a vision that Irwin Jacobs and those at Qualcomm in the 1980s had envisioned.
The authors of this book have achieved a very useful product which has a great demand. They have managed to write about LTE in a highly structured yet simple and direct manner. They cover all of the key issues at a level of detail which is perfect for those seeking to get updated as well as those who are starting out. This book is NOT a technical dissertation of LTE or wireless. If you have the expertise it fills out the edges, if you do not it will enlighten you.
The authors move through the book in a logical manner and at no point did I find them speaking down to the reader or making a presentation over simplistic. In a sense this is an overview but in a sense it is also a well composed detailing of LTE.
Unlike many of the other books I have seen on similar topics, this does not have the feel of some overused power point presentations with words interspersed. The flow of ideas is superb.
I would strongly recommend this book to anyone seeking to get a feel for the details of LTE.

IP for 4G Review

IP for 4G
Average Reviews:

(More customer reviews)
Currently, various telecom operators throughout the world are involved in building out 3g mobile systems. But a so-called 4g has been mooted by various parties. What is this 4g? And what might be the prospects of running the Internet Protocol over it? Wisely explores these questions in this recent book (2009).
The tone is somewhat informal, which may not be to some readers' tastes, so you've been warned.
Much of the book summarises many details about current 3g and wireless LANs. It is definitely a technical discussion. But part of the value that Wisely provides the reader is he steps back from the hugely verbose descriptions of many wireless schemes. To an engineering reader, enough operational details are given for you to appreciate the gists of the systems.
From a business standpoint, the key value might be in the final chapter. Assessments are offered for future mobile services and systems. Though scattered thru the book are other related observations. We see that some previous predictions by telecos have been awry. Notably that SMS was originally intended for diagnostics by telecom engineers, yet it has grown immensely as a popular mass mode of communication and a huge revenue source.
Another observation is that 4g, at least initially, might not involve IPv6. The latter keeps getting pushed further into the future. So if you are devising an IP over 4g application, you might design for IPv4, at least for the initial years of deployment.
Things have changed since I reviewed another book on 4g, 2 years ago, 4G Roadmap and Emerging Communication Technologies (Universal Personal Communications). That text had much to say on Digital Rights Management. In contrast, Wisely omits this topic. Possibly because the intervening time has led to an overall deprecation of DRM.
One thing that Wisely chronicles well is how the current telecos face a conundrum. They want 4g to be a major new revenue stream. But if they offer IP over 4g, there is a danger that they will be reduced to dumb pipes, just supplying commodity access to the Internet. Whereupon Internet based services like search engines and auction sites might garner most of the profits, as they have done with fixed Internet access. The telecos don't want to end up like the ISPs! Hence the possible rise of walled gardens with restricted access.
How will all this play out?

Mobile WiMAX: A Systems Approach to Understanding IEEE 802.16m Radio Access Technology Review

Mobile WiMAX: A Systems Approach to Understanding IEEE 802.16m Radio Access Technology
Average Reviews:

(More customer reviews)
This is a textbook and it seems to me that it's meant to be used in a classroom environment. That being said, it's not as dry as many that I had when I was in school.
After the preface and introduction the book launches into sixteen and a third pages of abbreviations and you need to spend some time with these pages as the abbreviations are used throughout the book.
There are twelve chapters here: Chapter 1: Introduction to Mobile Broadband Wireless Access. Chapter 2: WiMax Network Architecture. Chapter 3: IEEE 802.16m Reference Model and Protocol Structure. Chapter 4: IEEE 802.16m System Operation and State Diagrams. Chapter 5: The IEEE 802.16m Convergence Sub-Layer. Chapter 6: The IEEE 802.16m Medium Access Control Common Part Sub-layer Part 1 and Chapter 7 is Part 2. Chapter 8: The IEEE 802.16m Security Sub-Layer. Chapter 9: The IEEE 802.16m Physical Layer Part 1 and Chapter 10 is Part 2. Chapter 11: Multi-Carrier Operation. And lastly Chapter 12: Performance of IEEE 802.16m and 3GPP LTE-Advanced.
There you have it, a list of the chapters in this book. I'm no expert, not even a novice. I got this book for my nerdy brother who eats this stuff up. But I agreed to review the book and I sincerely hope that if you're interested in it, that the information I gave you above will help you.

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.

This book was one of the earliest books on LTE, the new cellular wireless standard that is expected to be commonplace in the next few years. This book is very good for people interested in learning about LTE from a systems architecture standpoint. It covers the EPS and SAE aspects of the system. It explains about the evolved packet core which is integral to the LTE system and also the newer and simpler network elements that constitute the overall LTE eco-system. For those interested in obtaining a deeper understanding of the protocol changes and such, I would recommend the following book by Erik Dahlman titled 3G Evolution, Second Edition: HSPA and LTE for Mobile Broadband.

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

As the author indicates at the beginning of the book, "From GSM to LTE" provides a comprehensive overview of this evolution of modern wireless technologies, in a single concise but comprehensive format accessible to anyone with a prior background in communications theory. It is a plus that the author avoids the mathematics behind these standards, instead focusing on the "how and why" of all the technical components of GSM, GPRS/EDGE, WCDMA/UMTS, and LTE, without going into the mind-numbing detail of the actual technical standards, which are nonetheless cited for those who wish to refer to them to actually implement these technologies. The book also has chapters on IEEE 802.16 (WiMax), IEEE 802.11a/b/g/n (WLAN), and Bluetooth, but I have not yet read them.

IP Design for Mobile Networks Review

IP Design for Mobile Networks
Average Reviews:

(More customer reviews)
Cisco Press has published many technical books about their products and about networking in general. But this book is a little atypical in that it seems to have far more detailed content. Also and perhaps pleasantly to some readers, the level of detail is not about an exhaustive explanation of the features of some Cisco product. You could construe this book as a timely discourse on numerous industry efforts at the intersection and integration of mobile networking (which is effectively equivalent to the use of cellphones) and the Internet.
One topic bruited about is the use of femtocells to improve cellular reach; especially inside buildings. Three methods are given - WiMax, UTMS and cdma2000. A chapter gives a detailed scrutiny of the latter.
For the Internet, there is much about IPv6. It seems far easier to handle cellphones and the movement of these via IPv6 than shoehorning the problem into IPv4. The reader might be struck by the idea that this, finally, could be what drives a large scale deployment of IPv6.
We also see that within IPv6, advances have been made. There are details of an improved next generation IPv6. Chapter 4 seems to be a key section of the book. Titled "An IP Refresher", it does not just cover the usual beginner's stuff about v4 and v6, but delves into cutting edge material.
Later portions of the book also explain how the 3G and 4G cellphone levels might evolve and tie into the Internet. The text is a useful complement to these recent offerings on 4g - IP for 4G by Wisely, and 4G Roadmap and Emerging Communication Technologies (Universal Personal Communications) by Kim.

As a newcomer to standardisation work, this book has proven invaluable and my only regret is that it wasn't available when I first started work on LTE about a year ago. The book has saved me hours of tedious scouring of standards text. In this respect it is valuable both for people who are in telcos management and need an overview of LTE, as well as standards engineers who are well acquainted with the topic as it will prepare them for a more in-depth look into LTE.
Some highlights include:
1. A great introductory overview of the evolution to 4G, impartial and technically sound.
2. An in-depth analysis of the physical layer of LTE. The details include state-of-the-art simulation results and highlight the technical achievements that make the promised transfer rates and quality of service possible. The results are preceded by background theory. I found the parts on OFDM and MIMO as key enablers particularly succinct and useful. Some abstract terms, such as the notion of control channels and antenna ports, are explained in a lucid and easy-to-follow way, showing you not just what LTE mandates, but also why it is designed the way it is and what the engineering drivers behind it are.
3. An overview of higher layers, more than enough to understand how the layered paradigm is implemented in LTE.
4. The consistency of the book throughout. In my opinion you rarely see books with so many contributing authors that flow as well as this one does. Clearly, a lot of effort went into maintaining a unified style and approach, and it was well worth it.
The editors-authors are active contributors to 3GPP standardisation, and so are most of the contributing authors (with some input from academia), representing many different companies. The book therefore has a unique quality of being impartial while coming straight from the source. While only a couple of pages long, the final chapter examines the future evolution of LTE: LTE-Advanced. Thoroughly recommended.

Overall, I am pleased with its content. It is clearly written. The topics are covered in a nice way that is comprehensive. The treatment of topics is balanced. Some topics are overemphasized but that may be necessary for people who are beginners in the field.
Many books are available in this field, but I believe this one is very comprehensive, especially emphasizing wimax and Lte technology no other book has done.

LTE for 4G Mobile Broadband: Air Interface Technologies and Performance Review

LTE for 4G Mobile Broadband: Air Interface Technologies and Performance

Working in 4G / WiMAX for last two years as part of team for launching the 1st Commercial Mobile 4 G network in Baltimore/Washington DC and being responsible for the 1st trail test bed in Arlington, I am always in look for 4 G materials and books.
This is one of the best books so far I have come across regarding the 4th Generating Mobile networks. The 400 plus pages are a power house of sheer knowledge and explanations regarding the 4th generation and LTE. The books covers almost every subject matter starting from the basic network architecture to the advance topics like Channel coding, MIMO, Scheduling, H-ARQ, P-Control, signaling details, so on and so forth. One of the best chapters I like is the Chapter 16 i.e. Page 409 to 425, where Interferences, cell edge, frequency reuse and loading is discussed. I believe that these are the must know topic for anyone who is going to design the Future LTE and 4th generation networks. The point I especially liked is the diagrams. The book has adequate diagrams which are clear and precise that describes the text in perfect supplement. There are also a lot of mathematical expressions which not only proves the detail explanations but also show the full command of Author of the subject. As said, the topics are well explained and we do not need any more details but never the less there is a detail list of references at the end of each chapter.
For me it is kind of hard to find a short coming of book as it is so well written and the author is a SME. We could have an extra cherry on the cake by have some more treatment of the IP / network regarding the LTE and 4th generation by beefing up the chapter regarding the network architecture and protocol. For marketing and management staff, I talked to they would like to have more of an extended summary in start of chapters without technical details. Last but not least, in due time it will be interesting to see how the real networks data compares out to the chapter 19 regarding the LTE performance and verification. I am sure both will be in perfect accordance.

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).
