    5-0 out of 5 stars Read "a different" book before this one.
    Otherwise it might be somehow confusing. This book is a must for professionals as another reviewer stated but it is not very suitable as the first book on UMTS technologies. This book serves best as supplementary reading. For example new-beginner readers might get confused talkink about SIP at the first chapter before explaining W-CDMA and core-network layout. Anyway, this book contains wealth of information on UMTS technologies and warmly recommended for serious readers.

    3-0 out of 5 stars Informative but not lucid
    Its a good book for starters and people getting to know the subject of wcdma and umts. But, the language is very bland and looks more of an ieee paper. Recommended for people who are indireclty associated with umts or similar products.

    3-0 out of 5 stars Useful compilation of standards, if you need them
    If you like to read standards or have to in the course of your work, this book offers a useful and succinct compilation. Other than that, there is nothing to recommend this book as it does not help improve your understanding. Then again, this is not the kind of book which people who do not have to work with standards will want to read.

    There is a short chapter on cdma2000 at the end.

    5-0 out of 5 stars Not for newbies, must for pros
    This book delivers exactly what it promises: a profound, compact and clear description of WCDMA for UMTS. The reader is expected to understand quite advanced concepts of mobile communications, hence it is not a good book for managers who want to know what 3G is all about nor for undergraduate students who want to learn cellular system basics. It is an excellent book for experienced network planners, protocol designers or research engineers, for example, who want to move from 2G to 3G. Simple test: if you don't know what are Erlang-B, orthogonal codes or layered protocol architecture, you want to study them first from another book.

    2-0 out of 5 stars umts
    With UMTS you must read what you can get - unfortunately what you can get is not aleays what you want - so with this book. Although the authors seem well informed, they are not god communicators - their explanations are alternatively trivial or incomprehensible, their diagrams, in most cases copied slavishly from the specifications, explain nothing. Perhaps this book is useful as a reference after the subject is comprehended. Comprehension does not lie here. ... Read more

    5-0 out of 5 stars A non-commonly found textbook on Digital Image Processing
    I've been a senior researcher in Image Processing for more than 20 years, and my opinion of the book Digital Image Processing of Gonzalez and Woods, is that it is significantly superior to current books on image processing. The contents of the books are in the mainstream of work in this field, and the level of coverage is complete and written at a level that makes it an ideal textbook for seniors and first-year graduate students. The experience of the authors shows through in the way the material is presented and illustrated. The complementary web site is an outstanding teaching aid.

    5-0 out of 5 stars A good text book in image processing class
    A good book, clear and easy to understand, and it is also easy to implement the algorithms mentioned in the book into a real world program. I used it as a text book in image processing class. Compared to other books in image processing, this book is a clear winner. The only drawback is the price. Other thing to remember is that this book is old enough in the ever-progressed image processing and computer graphic field.

    3-0 out of 5 stars Needs some enhncements
    The book is fairly good but it lacks of examples

    5-0 out of 5 stars Low Price Edition
    On this site, there are already good reviews of this book.
    So I would like to post only a comment on the "Low Price" or "International" or "Indian" edition:

    IT IS VERY VERY CHEAP and LOW QUALITY

    The pages are almost transparent. While reading a face of a page, you can guess what is written on the other face. Definitely annoying.

    5-0 out of 5 stars Serious Image Processing for Students and Practitioners
    This volume covers the waterfront of image processing from a reasonable introductory level. Refreshingly, it is much more than a cookbook. The authors pay attention to the physical principles that imaging and image manipulation are based on. With many quality images and examples, there is much for the less mathematically inclined to cut their teeth on while brushing up on their advanced math skills. The inclusion of many well chosen problems makes the book a valuable volume in a student's library. The book's associated web-site is a major bonus for the reader. I did find that some of the figure captions were challenging to interpret but the problem does not seem pervasive. Overall, I liked the book. It is a valuable addition to the image processing literature and to the image processing textbook selection. ... Read more

    This book is in awesome shape, I used it for an online course, so i have never carried in a book bag. No markings, and very very minimal corners bent.

    5-0 out of 5 stars Interesting and real world scenarios
    I teach technical writing at a community college and frequently switched textbooks until I discovered Mike Markel's. It is well organized, gives 8 measures of excellence in technical writing that students quickly grasp, has very up-to-date scenarios that prompt critical reading and writing and the online quizzes and resources are the frosting on the cake. This book is a great tool for educators, students and absolutely anyone who wishes to write in a professional manner.

    3-0 out of 5 stars Well written, over priced common sense.
    The information in the book as well as the scenarios presented are well put. The writing is adequate for the subject. Overall, though, I feel the cost of the book exceeded the value. Much of the information in the book is common sense.

    4-0 out of 5 stars Technical Communication--Mike Markel
    I am using this for my course in technical writing at the University level. It gives a very thorough look at tech writing, and its exercises help emphasize ethics, collaboration, and working with the Web. All of these are important in the world of business that many students will be entering. Although I could not possibly cover the entire text in one semester, it is carefully laid out so that it is easy to emphasize the things that work best for your course. ... Read more

    4-0 out of 5 stars The DSP Bible
    As others have said, this is the DSP bible. I have worked in the field of DSP as a post-grad student, lecturer ("professor") and an R&D engineer for over 10 years now and this book is in my "must-have" collection. It is the book I learnt my DSP from; it is the book I have taught DSP from; it is a very good reference book for the practicioner.

    Having said that, I should also point out what I believe this book is not (and why it gets only 4 stars) : it is not a good book for self-learning. If this is what you are after, I recommend Rick Lyons' book "Understanding Digital Signal Processing" (five stars from me).

    If you are a mechanical engineer learning DSP, I suggest asking your local Bruel & Kjaer representative if he'll give you a copy of Bob Randall's "Frequency Analysis" published by B&K (ISBN 87 87355 07 8; "only" 3.5 stars, but 4.5 stars if you're a mechanical engineer).

    4-0 out of 5 stars On the difference between 2nd Edition and 1st Edition
    I used the author's book "Digital Signal Processing" in my college study, and I also read and cite the 1st Edition of
    "Discrete-Time Signal Processing" during my work experience. That's a very good reference. But I don't have the
    2nd Edititon.

    However, after going through the Table Of Contents of the 2nd Edition of "Discrete-Time Signal Processing", I
    think Oppenheim&Schafer did a resaonable tradeoff to reflect state of the art in DSP domain.

    They add: Discrete Cosine Transform (DCT) which is mostly used in image compression, Multirate Signal
    Processing which is used widely in modern DSP, and Oversampling and Noise Shaping Sampling for A/D and D/A
    conversion.

    In consequence, they remove: Lattice Structure, IIR Filters Design, Cepstrum Analysis (often used in speech
    signal processing) and Homomorphic Signal Processing, which are a bit sophisticated. And I guess the reason to
    remove IIR Filter Dsign is there exists many computer-aided tools on digital filter design, and made this very easy.

    3-0 out of 5 stars Ok beginners book
    This book seems to follow the disappointing (to me at least) model of many engineering texts--that being the reluctance to present new mathematical concepts/techniques. Almost every mathematical concept/technique used in this book was already covered by the prerequisite text by Oppenheim, "Signals and Systems." It would seem that a subject so entrenched with complex numbers and polynomials could be taught in such a manner that would include theorems and concepts from these well-established mathematical disciplines. Note that I did not read the chapter on Hilbert transforms, or the section on the Discrete Cosine Transform, so I cannot comment on them. I did read all other sections. The sections on random signals do introduce new concepts, but they were only put in as a quick review of concepts meant to be studied in a random processes class. On the other hand, this is a very readable book, which has proven very useful. It does present MANY new engineering concepts. If analytic function theory had been introduced, this book probably would not have room left to be as complete a reference for existing introductory DSP theory. However by avoiding the math it has limited the continuing students ability to develop insight into deeper theory, or develop new theory.

    4-0 out of 5 stars Very good reference
    This book has its share of shortcomings, but overall, it is probably the best and most complete reference on DSP. Unfortunately, it does skip a few important topics. For example, the second edition threw out the section on designing IIR bandpass and highpass filters from lowpass prototypes. This section used to be in the first edition and is VERY important, so I don't see how Oppenheim & Schafer could have justified throwing it out. They also conspicuously left out filter design based on the frequency sampling method. But in spite of these omissions, it's hard to recommend another book over this one. The one that comes closest is Mitra's.

    In the end, if you want to learn DSP and work in the field, you have to have this book, as well as the ones by Mitra, Proakis & Manolakis, Jackson, and, of course, Rabiner & Gold. If you get all those, you'll have the complete reference of CORE DSP texts.

    5-0 out of 5 stars Reference or introduction?
    I found this book to be an excellent fundamental text about DSP. But is it a good introductory book for beginners? Well, it depends... The book covers the essential topics in great depth and that means every one of its 800+ pages is packed with concepts and details and examples. The style is clear, but the amount of information can be a little overwhelming when you read it for the first time. If you have time, patience, a good maths background, the desire to master the subject, and someone to clarify your doubts, this can be the best first book on DSP you could ever buy. If you just want to learn the basics, and don't have much time or patience you should probably look elsewhere. ... Read more

    2-0 out of 5 stars this is not your book if you want hardcore technical details
    I can recommend this book to everyone who wants to get an overview on SDH/SONET capabilities and/or products but does not care for the protocol itself.

    But if you're looking for a good and correct description of the inner workings of the protocol you'd better not waste your time with this book. Check out the SDH/SONET bible: Broadband Networking: ATM, SDH and SONET by Mike Sexton and Andy Reid. It's expensive, but it's really worth the money.

    Goralski's book doesn't keep up with the promises of it's blurb. it has, like every book, some technical errors in it; errors which are IMHO worse enough not to buy this book. i wonder how this pointer-processing-example came into this book - horrors!

    ...

    5-0 out of 5 stars Easily read - full of historical and technical information !
    Goralski certainly did his research. He presents the SONET architecture in a way that most would find comfortable. I found myself knee deep in an FOA for DSL technologies beyond the NGDLC and needed SONET information FAST ! ! The book reads almost like a great novel, I can't put it down! Most books of it's size are rarely organized well, and serve mostly for technical references. Bravo for an excellant effort Mr. Goralski ! !

    3-0 out of 5 stars Good Book To Start Sonet Studies
    This is very good book for beginners, and for those who wants to understand Sonet basics, but still it very general and lacks from some shallowness.
    So for designers and network operators it will be not so useful since it's not detailed enough.

    1-0 out of 5 stars Don't buy e-books...
    The content of the book, "SONET" is rather good: it covers history, architecture, equipment, lots of technical and implementation details. However, don't buy the e-book, consider the printed version. The rating really should be 0 stars, but 0 is not allowed...

    The e-book version is difficult to read, and the reader is cantankerous, lacks ALL of the advantages of a printed book, and has NO electronic advantages: it's bound to the PC it's loaded to, and cannot be moved. If your PC crashes, you're cooked. Plus, you can't return it if you find it's not the right book for you. I'll never buy another e-book!

    5-0 out of 5 stars An accurate, well-aimed work
    As an author of technical books myself, I am always looking for titles that tell the story of a particular technology in a comprehensive, clearly-written and standards-oriented fashion. Walter Goralski's books do this and do it well. I own all of his titles, and the reason I like them (besides the author's sense of humor) is the fact that they are written around the standards that govern the telecommunications industry. Many companies interpret the standards and the terminology in different ways, which is fine - that's how they are designed. Unfortunately, this sometimes leads to differences of opinion about meanings or interpretations. Walter sticks to the standards, however, always ensuring the availability of a literary technological benchmark.

    I strongly recommend the book. ... Read more

    The authors of Voice over IP Fundamentals--three packet-voice specialists at Cisco Systems--initiate their exploration of next-generation technologies for supporting conversations across large distances: the switched telephone network as implemented on large (intercontinental) and small (building and enterprise) scales. They then point out problems with the old way of doing things and illuminate the standards and regulatory conditions that have made Internet telephony attractive. Signaling System 7 (SS7) gets particularly insightful coverage, with ample graphical support for the clear, fact-rich, example-laden prose.

    The authors do a great service for readers by breaking packet telephony into its component technologies and explaining each one carefully. Coverage of the various protocols that enable voice over IP, particularly H.323 and Session Initiation Protocol (SIP), is simultaneously clear and deep. The same goes for media gateway protocols and various schemes for translating sounds into digital signals and back again, while retaining maximum clarity. There's even some practical material; concluding chapters diagram Cisco router configurations for voice traffic and flesh out solutions with case studies.

    You'll like this book if you need to implement a voice over IP system and know more about IP than you do about traditional voice telecommunications. The patient and detailed explanations of traditional telephony concepts and voice over IP protocols will mesh nicely with your existing data communications knowledge, enabling you to make wise design and product decisions. --David Wall

    Covered topics: The Public Switched Telephone Network (PSTN), signaling specifications (including Bell System, ISDN, and Signaling System 7), the basics of Internet Protocol (IP), modulation and compression of voice, Quality of Service (QoS), H.323, Session Initiation Protocol (SIP), and gateway protocols. Business considerations of Internet telephony are also addressed. ... Read more

    5-0 out of 5 stars Very good book on VoIP fundamentals
    This book is the one to read if you want to know something about the basics of Voice Over IP and the protocols which are involved like H.323. It also gives you an introduction to the POTS ( plain old telephony service ) standards. So, if you are new to VoIP and want to read about it from the ground, buy this.

    But it is not the right choice if you are searching for preparation material for the cisco #640-647 cvoice exam. For that exam you also have to know something about VoFR and VoATM, which is not covered deeply enough here.

    2-0 out of 5 stars Difficult book to read and understand
    Although this book is but 15 chapters and 336 pages long it took me an incredible amount of time to read through it due to the complexity with which it was written. I've read several Cisco Press books in the same time it took to read this one! Further, I found myself asking the question over and over again, "If this book is about the fundamentals of Voice over IP and is 'A Systematic Approach to Understanding the Basics of Voice over IP', why is it difficult to grasp even the 'basics' as presented by the authors?" As stated in a previous review, the authors have a great understanding of the topics, however, like my Theory of Operating Systems instructor, they do not do well in 'dumbing' down that information to me, a layperson in this field. This book was definitely written by VoIP engineers for VoIP engineers, not for beginners like myself.

    2-0 out of 5 stars Best suited for Telephony engineers
    Strong Points: -The people who wrote it are definitely knowledgeable: They have loads of information about almost every topic they discuss -Chapter organization: the chapters are well organized as far as the order in which to expose a reader to the topics, building up to the next. Weak Points: -In almost every chapter, the author(s) frequently mention or compare the topic being discussed with an actual Cisco product. While many people agree they make good products, including myself, this book should be about the VoIP as a standard (as the title implies), not Cisco's products. -The author(s) explain most topics by throwing tons of (or too much) information at the reader, including exceptions to the rule - all in the same sentence. Some of the key points are not even mentioned or elaborated on, while the author goes to point out small or insignificant details. -While discussing the history of Telephony and VoIP technology, the use of acronyms is unavoidable, but the author(s) overuses them to the extreme. At times, there are synonym acronyms that the author(s) will use randomly and interchangeably in the same chart, diagram or sentence; this is highly confusing. Also, there is no glossary, so you have to waste time flipping back through the pages to look up acronyms they spelled out once. Many acronyms are not even defined - they are just mentioned as casual talk to define other acronyms (so have your internet browser ready). -The author(s) frequently define topics and acronyms sections or chapters after they are first mentioned. This is also very confusing and frustrating. -The book is filled with charts and graphs. Most of them you really have to study to understand because they use many little pictures for which there is no legend, and some you flat our need an electrical engineering degree to understand.

    3-0 out of 5 stars Worth Reading, But of Limited Use
    I've had the Davidson book on the shelf for about a year and finally picked it up for a careful read to help me prepare of Cisco's CVOICE exam. While the book is useful toward that end, I recommend it only cautiously.

    No doubt part of the problem is mine; by background includes extensive data but very little voice experience. I found the topic Signaling System 7 and similar topics to be slow reading, and I questioned the value of the IP tutorial. A reader with the inverse of my background may have exactly the opposite experience.

    This book is unusually dense with acronyms, even for a technical book. The nature of the topic makes acronyms unavoidable, but I felt the lack of a glossary was a serious deficiency. I frequently found myself flipping back and forth through the book to decode an acronym to no avail. Thorough readers might want to construct their own glossary with index cards.

    I also had the sense, especially toward the end of the book, that I was getting less of an explanation of the technology than a simple compendium of features. This was especially evident in those thin sections on the Session Initiation Protocol, the Simple Gateway Control Protocol, the Media Gateway Control Protocol, and the Virtual Switch Controller. I found the sections on the H.323 Protocols and Quality of Service more useful and complete.

    Given the ambitious scope of the book, I believe the author could have provided a more readable and understandable treatment with six or seven hundred pages rather than the three hundred plus provided. Still, I find my understanding of the subject to have increased substantially. It is a fact that there are few alternatives. I give the book a qualified recommendation. Read it slowly and carefully, mastering acronyms as you go, to maximize its value.

    2-0 out of 5 stars Fragmentation is necessary because of serialization delay
    Fragmentation is necessary because of the time it takes to output bits in large frames on slow serial links. This time is called serialization delay and it is relevant for low-speed interfaces where delay-sensitive voice packets might need to wait a long time while a long frame is pushed out the interface, at say, 64 Kbps. Propagation delay is not the issue. This seems like a very basic telecommunications 101 issue that the authors should not have gotten wrong. ... Read more

    4-0 out of 5 stars Good collection of concepts
    This book has a very good collection of most of the concepts related to RFID and is very useful especially for beginners in RFID. I gave only 4 stars as I was dissappointed not to see any examples for any or almost all the concepts explained. For what it costs, I think it makes sense to add some examples liked to some important concepts.

    5-0 out of 5 stars Great book for understanding the concepts and applications
    If you are an Engineer looking to understand the history, technical aspects, implementation, standards and details of RFID systems, this book provides an excellent introduction for you.

    The chapters are well laid out and paced. The author explains the most common devices and systems available in the market, their technology and concepts quite well. Most of the RFID related standards have been covered along with relevant examples. The author covers such things as the hardware design specifications for devices, software requirements, and some basic RF concepts that are required to understand Transponder and Receiver designs.

    If you need specifics about recent products however, you might want to research for other sources of information because this book does not cover vendors and products in detail. For readers without technical background, the book introduces the concepts well; but some content might not be relevant because of the [technical] nature. ... Read more

    2-0 out of 5 stars A textbook for college business majors (only?)
    If you want a general IT book then don't even think about buying this one, despite its title. This is a textbook for college business majors, and looks at things from the business angle.

    The book is less suitable for non-student readers. It is geared for use by a lecturer who can draw attention to the important concepts underlying the field of IT, and can steer students to useful supplementary material.

    The book races across the surface of the whole field of IT. The authors have packed in a lot of material, but at a cost.The explanations may be good enough for students to answer a quiz about the various buzzwords, but there is not enough space here to cover anything in depth. The students, and you, may be left without a clear idea of what the words really mean.

    At the other end of the scale, the book struggles to make plain the broad sweep of IT concepts. Although the authors try hard, ideas tend to get lost amidst the large number of factoids.

    One book is never going to be enough to cover all of IT.Your choices are to be more selective about which area you want to learn about, to pick a book which is more clearly aimed at being a simple overview, or to buy this book and work really hard at following up its leads to other material to fill in the gaps. ...

    2-0 out of 5 stars Content seemed great, but not explained in detail
    When I first bought this book, I was very hopeful. The book seemed to cover a lot of relevant material, in a concise fashion. When I tried to read it however, I found it a little bit too much on the concise side. I have read very complicated books with a lot of math before, and I could follow them easier than this "easy" writing style. Almost every subject is covered in other books in more detail and better. Sometimes it's nice to have a simpler book which is an introduction, and that is what I was hoping for, but this just didn't do it for me.I donated the book to the library,as I felt I would never really get too much out of it. This didn't stop me from buying Mr. Razavi's "Design of Analog CMOS ICs " and I liked his tutorial in the IEEE Phase Lock Loop book he edited.I know he can do a better job.

    4-0 out of 5 stars Easy to read
    As a hardware design engineer, I am currently pursuing an 'economy' 900 MHz frequency hopped data modem design. I have limited experience with >200 MHz designs and found this book very useful in conveying techniques used at these higher freqs. Straight.. to the point discussions.. in which every sentence actually says something and instills insight. I esp found the sections on freq synthesis and oscillators to be informative. It's also a good reference to break out for descriptions of all the modulation techniques. However, I am still searching for that one text that performs in-depth analysis on the ever present / nebulous 'carrier recovery' and 'bit recovery' blocks.

    4-0 out of 5 stars My impressions of RF Microelectronics by Behzad Razavi
    I have read large sections of this book and have been pleasantly surprised by the care and attention to detail taken with the description of RF design concepts as well as the mathematics used to clarify the issues.

    The mathematics in particular seems to be free from errors, used only when necessary and does not contain such large jumps that the reader has to spend much effort trying to follow. All in all it is one of the best texts I have ever come across in this field of engineering

    5-0 out of 5 stars Excellent RF circuit design book.
    This book will help analog circuit designers who always wanted to learn what is going on the RF front. Most of the books on RF circuits are outdated and uses only discrete solutions.

    5-0 out of 5 stars Great book that fully serves two purposes!
    If you are looking for a book on Wireless LAN security, this is it. If you are considering the CWSP certification and want a great resource to help you prepare, this is also it. This book is not a study guide, regardless of the title. It IS a fantastic book on WLAN security, what it is, what the challenges are, what the responses should be, and how to implement them. That is also can help you prepare to sit the CWSP exam is a bonus provided by the "real-world" nature of that exam. If you are a WLAN implementor or an administrator, you need to get this book and read it cover to cover. It misses NOTHING!

    5-0 out of 5 stars Excellent resource and CWSP study guide
    This is an excellent study guide for the Certified Wireless Security Professional (CWSP) exam # PW0-200 covering all of the CWSP exam objectives in detail. This guide is filled with useful information and resources to help any organization identify the most common security holes hackers use to gain access into wireless networks and this book offers plenty of illustrations and ideas to help you secure those holes. I attended the official five-day CWSP training class as well and I have found this book to be a great study aid while preparing to take the CWSP exam. As a security professional specializing in wireless network design, implementation, and security remediation services this book has also been a great resource to recommend to my clients since I have found that it helps a layman understand the technology and the threats much better than the majority of other books and magazine articles supposedly addressing Wi-Fi security issues.

    5-0 out of 5 stars Another Great Book...just one question though!
    The Devinator does it again with a superbly written book. However, did anyone notice the review questions for Chapter4??
    The chapter talked about DOS and the questions were about Encryption? Is this a typo or was that intentional?

    5-0 out of 5 stars Technical editor's comments
    I spent many, many hours going over the CWSP Official Study Guide. I feel like Devin Akin did an awesome job of authoring it. This book was developed to help people attain the Certified Wireless Security Professional certification but I use it whenever I need a definitive answer on questions related to wireless security.

    A ton of research was put into making sure all types of wireless security products were covered and I think you'll benefit not only from the challenge of the CWSP exam but also from the knowledge you'll gain while studying for it. I can certainly vouch that undertaking this complex subject has definitely helped my career in the IT industry. Getting the CWNA and CWSP certifications could do the same for yours.

    5-0 out of 5 stars Wireless Security Bible - AMEN!
    I have read three other wireless security books and they all basically [stunk]. Some of them had three or four good chapters, but they also had a lot of "fluff" material and just did not cover the material in a logical manner. This is by far is best wireless security book published to date. Even more important than being a study guide, the book will become your permanent reference book when deploying solutions in the real world.

    The book covers a wide range of wireless networking security solutions including 801.x, 802.11i, DES, 3DES, AES, WEP, WPA, TKIP, PPTP & IPSec VPNs, wireless VLANs, EAP, EAP-TLS, LEAP and EAP-TTLS. It covers numerous Layer 2, Layer 3 and even Layer 7 solutions.

    The guide also has a great section on wireless security auditing tools. In addition there are several chapters that discuss the implementation of security policies and why corporations need wireless security policies in their company handbook.

    Although this book is the best wireless security reference book available, I would still highly recommend that you take the CWSP class which is about 80% lab with about 35 hours hands-on with the equipment. The guy who writes the tests for Planet3Wireless is the Marquis de Sade of test creators. He is sadistic, but bottom line is that I was forced to learn and understand the material and concepts. Hands-on experience combined with intense self study from this study guide will enable you to pass the CWSP test.

    But regardless of whether you plan on getting certified or not, this book will be your Wireless Security Bible. ... Read more

    4-0 out of 5 stars A good basic introduction to telecom tech
    I read this book while I was a legal intern at the FCC to try to learn the tech side of the telecom world. I knew policy, but I had no idea how the telephone network actually worked. This book gives a great basic grounding in the technology of telecommunications-switches, routers, time division multiplexing, and everything else.

    Luckily, basic is exactly what I needed. The "tell it to me like I'm a two-year-old" approach might be frustrating for some advanced readers. I found myself skipping some of the sections on the Internet because it was too elementary for me.

    Also, if you're going to read it, make sure you get the latest edition of this book. Technologies change fast, and some of the sections are bound to become out-of-date very quickly.

    Once you have the tech side down, you can pick up the regulatory policy side by reading The Telecommunications Regulation Handbook available for free from the World Bank. It's just as basic as Dodd's book, but is better read if you know how the technology works. Get these two under your belt, and you'll be ready to work at your local friendly telecom regulatory agency.

    5-0 out of 5 stars Great Overview Of Telecom Technology
    The Essential Guide to Telecommunications is probably one of the most well written and useful telecom books you will find..

    Annabel Z. Dodd does a great job in capturing a snapshot of the current telecom industry, in all of its different flavors. You will find technical overviews of numerous telecom technologies and transport methods. These include business telephone systems, circuit switching, local and long distance networks, cable, wireless, cellular and PCS, paging, Voice Over IP, satellites, broadband services, DSL, T-1's, ISDN, ATM, and much, much more.

    Dodd's writing is understandable and enjoyable to read. Even those with little or no technical knowledge should be able to understand the text. The author seems to assume that the reader has only a minimal amount of technical knowledge, but does know something about the telecom industry in general. This is the perfect book for telecom salespeople who want to learn more about the products and services they are selling, or for those who just want to keep up-to-date on the latest in telecom technology.

    This book not only gives you explanations of how various telecom technologies work, but compares them side-by-side from both technical and practical (business) points of view.

    Where and when does using a wireless network make sense? What type of fiber offers the most capacity? How many T-1's are in a T-3? You will find the answer to all of these questions and more in The Essential Guide to Telecommunications. I highly recommend it.

    4-0 out of 5 stars Good Intro/Overview of the Telecom world
    I just finished reading this book and overall found it to be very informative. It covers a general overview of everything from the Telecommunications Act of 1996 to telecommunications around the world. Landline, wireless, and internet are all covered along with the technologies that make them work. With that being said, this book will NOT make you an expert in telephony or any specific area of telecommunications. It is however, a great start.

    The one problem I had with the book was numerous grammatical errors. I found that in some cases I had to mentally disassemble and rebuild a sentence to understand what was trying to be said.

    I would (and have) recommend this book to a coworker and/or friend getting started with telecommunications.

    5-0 out of 5 stars Number one Telecom Intro Book
    Magnificent! Perfect example of a Technology book everyone can relate too. After finishing this one, I was desperately looking for any other technology book written by this author, couldn't find any. Looking forward to find more books from this Author..

    4-0 out of 5 stars My first book on this subject: Very good
    I bought this book with a little bit of apprehension. As I don't know much about telecommunications I thought it was going to be too hard a reading. It came out pretty good. I can say that after reading it I got a good broad picture of most of the subjects treated.
    Maybe the only inconvenience is that on its own it isn't enough to give a full understanding of the whole thing. I am already thinking of buying another book to further my knowledge. It also starts stright ahead with terms and names that will be clarified only later on in the book. Still I think it is a wonderfull book for the first step. ... Read more

    Book Description

    From leading WorldCom engineers--expert guidance on how to plan for SIP implementation
    Session Initiation Protocol (SIP) has gained tremendous market acceptance since it became an official IETF Internet communications standard in 1999. SIP is the technology that makes it possible for multimedia communications sessions on the Web--ones that allow voice, video, chat, interactive games, and others to run all at the same time. Now that the deployment of real SIP networks is about to take off, two leaders of the commercial rollout deliver complete guidance on this exciting new technology. Geared to IT and networking professionals and decision-makers at Internet service providers (ISPs), as well as networking (NSPs) and application (ASPs) service providers, this book helps readers sort through the available vendor offerings and services to discover how to integrate and maximize SIP's power across their networks.

    our new shinning star SIP in IP Telephony , book is nearly perfect to demonstrate the capabilities of SIP , good to follow inlink RFCs .

    5-0 out of 5 stars An Updated Holistic view of SIP
    A highly recommended book for newcomers to SIP as well as SIP experts. What I liked about the book was updated information on supplementary SIP technologies like PINT, SPIRITS, security et al. It has a very brief yet pertinent introduction to such areas. A very good companion to 'Understanding SIP'.

    5-0 out of 5 stars An Outstanding Book on SIP
    I'll keep it short and sweet. I am one of the authors of SIP and
    of many of its related technologies that are discussed in
    this book. As such, I am frequently asked by people how they
    can quickly understand the benefits of SIP technology, why
    it is important to them, and what it can enable. The answer is
    simple - read the Sinnreich/Johnston book. The book helps you
    understand how SIP, its extensions, and related technologies
    all fit together, and why SIP is revolutionizing communications.
    This is a fabulous piece of work, written by two recognized
    leaders. I highly recommend it.

    5-0 out of 5 stars Wonderful!
    This book is wonderful because this is not a textbook for SIP protocol itsself but is a book representing what SIP being characterized and how different from other voip protocols and what we can do using SIP focusing to the INTERNET COMMUNICATION not just voice over IP nor video over IP. This book is very helpful when we systems engineers propose our customer what additional applocation services can be provided by the system using SIP.

    5-0 out of 5 stars Must Read -- This book explains the "why" of SIP services
    I've been involved in the development of the SIP specification for several years, and currently co-chair the Internet Working Groups overseeing its continued evolution. I'm closely involved with the application of SIP to next-generation mobile phone networks. Between standards work and speaking on SIP frequently at trade shows and conferences I've seen a lot of SIP books and tried to explain SIP to many people. Most of the books on SIP cover the dry technical details of the specification and implementations. This book, "Internet Communications Using SIP" goes into an entirely different realm.

    Henry Sinnreich and Alan Johnston are two of the most knowledgeable authorities and notable figures in the SIP world. I expected a lot from them them. They've greatly exceeded my expectations, doing a surprisingly good job of explaining WHY the SIP protocol works the way it does, WHAT sort of advanced services it is making possible, and HOW service providers can use it to enrich their business offerings.

    This book is an absolute "must read" for anyone in the industry, especially for people familiar with traditional telephony who are trying to design, market, or implement new telecom services of any kind. If you haven't read this book and Gonzalo Camarillo's new SIP book, don't argue with the old-timers on the SIP mailing lists -- they're likely to just tell you to "RTFB" . . . and this is one of the books they're referring to. ...

    5-0 out of 5 stars Best introductory book I've seen
    This is easily the best introductory book I've run across. It covers a wide range of topics in a manner that is conversational rather than dry and boring. It's an easy read and they make some very complicated subject matter very easy to understand. I was constantly amazed at how the material sprang off the page. Some outstanding historical material as well -- excellent overview of where the phone system came from.

    4-0 out of 5 stars Best introductory communications text I've seen.
    This book is easily the best introduction to voice and data communications I've seen. I wish I had this when I first got into the business 10 years ago! Jargon isn't used until after it's introduced, text is plain and easy to read, and illustrations are clear and informative. My only quibbles are the index could be better, and a larger glossary would be very nice. Also, it's not quite as up to date as I had hoped it to be; for example, it talks about V.34 as a pending standard, and no mention is made at all of V.90. Nevertheless, at $65, this 900 page book is well worth the price.

    2-0 out of 5 stars Confusing and Incorrect
    I puchased this book, in addition to many other telecom books and found this to be one of the worst ones. Not only is the information useless it is written in a diffucult to understand fashion. I recommend that you do not waste corporate money of this book.

    But right after that I have to say that I can't read more than 10 pages in a row without finding a glaring error. For example, the term "jitter" is defined twice in two pages. Why? Plenty of typos, some of the illustrations look like the postscript monster ate them, and the 1,000 pages could easily be condensed to 500-600 by getting rid of redundancy.

    For example, the difference between analog amplifiers and digital repeaters is defined around 5 times in the first 300 pages (with more or less the same illustration at least two of those times). So, yeah, I get the concept now and couldn't forget it if I wanted to, but I didn't need to be told so many times.

    All that said, if I would recommend this book to anyone new to telecom, but advise them to be gentle critics or keep their red pens handy.

    I am a senior engineer for network security operations. I bought "Voice and Data Communications Handbook, Fourth Edition" (VADCH:4E) to gain a general understanding of communications technologies beyond the LAN. Although the book mentions all of the systems which interested me, I was not satisfied with the manner in which they were covered. VADCH:4E is better than Ross' "Telecommunications Technologies" but inferior to Green's "Irwin Handbook of Telecommunications." Nevertheless, I'm still looking for an author who delivers the goods on voice and data communications essentials.

    VADCH:4E's table of contents is sure to impress; it mentions T carriers, VPNs, X.25, Ethernet, Token Ring, FDDI, SMDS, Frame Relay, ISDN, ATM, DSL, SS7, LNP, Cellular/PCS, WAP, 3G Wireless, SONET/SDH, and other key telecom systems and concepts. Unfortunately, I rarely finished a chapter with a good grasp of the material. I desperately searched for clues to questions I felt were key to understanding each technology. Rather than launching into an extended discussion of each system, I would have preferred hearing exactly how each technology works, with comparison to other technologies. More is not better if the "more" isn't helpful!

    VADCH:4E is advertised as being "straightforward and jargon-free." This approach supposedly appeals to management types. In reality, the book swings wildly from mind-numbing grade-school-level analogies to material only understood with outside references. A 1074 page book needs to pick a writing style and stay the course. Otherwise, it alienates both nontechnical and technical readers. (Incidentally, technical readers may wonder why the authors believe Windows screen savers contribute to LAN traffic; see page 674 to read this odd claim.)

    On a positive note, VADCH:4E consistently offered useful information on the history and business rationale for many telecom systems. Many of the connectivity diagrams were excellent. (These were usually offset by cheesy "clip-art" type graphics elsewhere, unfortunately.) VADCH:4E also includes descriptions of the framing formats for most telecom transmission systems.

    Overall, I don't recommend reading a book this large if it doesn't answer the key questions I expect readers to ask. While I'm more familiar with telecom basics after reading VADCH:4E, I still hope another book makes more sense of the telecommunications environment. ... Read more

    3-0 out of 5 stars It's got lots of maths...
    But as an undergrad with GPA 5.8 (~distinction), this book really doesn't explain to ME the maths in an engineering context. For example, Chapter 3, with Orthonormal/Orthogonal signals, had me completely left in the dark as to why, as part of my job as a microelectronic engineer, I would want to orthonormalise a bunch of signals, even though the introductory paragraph goes:

    "Orthogonal representations of signals are of general importance in solving many engineering problems. Two of the reasons this is so are that it is mathematically convenient to represent arbitrary signals as a weighted sum of orthogonal waveforms, since many of the calculations involving signals are simplified by using such a representation and that it is possible to visualize the signal as a vector in an orthogonal coordinate system..."

    It then shows me some square waves that are apparently "orthonormal" and proceeds to dive straight in from there with the maths. In my subject we wrote a matlab program to show the orthonormalised version of a bunch of exponential signals (t^n where n=0..5); now /those/ final waveforms helped me understand better, but still..

    Personally I find a lot of the maths quite ugly (orthonormalisation is just an example that could have been explained better), which I guess is the nature of the subject. But then maths isn't really my strength (I get Credits for my maths subjects) - and perhaps other readers find this book more inspiring. I have talked about this book with fellow students and I can only conclude (personally) that students with only an average ability/interest in maths will perhaps struggle with some of the proofs and find themselves "just remembering".

    Perhaps this is simply a property of the subject in general, in which case I'm not as smart as I think I am, but I haven't read any other books to compare. The author clearly knows his stuff, but I don't - I study 5 other subjects full time and I do some contract work. It seems he has forgotten that things aren't necessarily as obvious to the reader as they are to him. Actually, it seems this is the case with my current lecturer also, so I'm really not liking "Signals and Systems" at the moment.. especially since my copy of this book I [bought] AUD for was stolen before I really had a chance to go through it.

    Lots of detail, but probably too much. If this is you're only recommended text, go to your lectures. This book appears to be the "algebra of signals", and no more.

    Theoretically, the flow of explainations is Okay. The problem is that it contains too much material for one semester course(for an introductory couse), too much math and examples. It also lacks a CAD package such asmatlab and simulink to support the book. The package becomes a must for acurrent textbook nowadays. More clear concepts rather than too much mathexamples and more practical application examples are hopeful.

    Overall this books is only okay.It emphasizes formulas and procedure way too much.Concepts are short, if concepts are explained at all.Basically, it lacks the necessary theory.
