Power Management in Mobile Devices (Communications Engineering) Review

Power Management in Mobile Devices (Communications Engineering)
Average Reviews:

(More customer reviews)
This is a quite useful book for anyone who needs to deal with power consumption in portable devices, sensor networks, or other low-power applications. The book covers a broad array of topics: transistor process technology, ASIC design methodology for low-power circuits, software optimization, batteries, regulators, and displays. For the reader who is generally familiar with embedded systems, this book is a very nice quick way to catch up on what's being done in all the aspects of power-sensitive system design. While the material is not terribly deep or mathematical, some background in electrical and/or software engineering is needed to benefit from many of the discussions. A nice list of references is provided at the end of each chapter.
Cavils are mostly minor. The book is stylistically disfigured by a number of incomplete and ungrammatical sentences. Some passages read as if they were lifted directly from vendor sales collateral; it would have been nice to have the author's critical evaluation of products rather than or in addition to the vendor's marketing materials. In some of the circuit diagrams, boxes are used for resistors and/or inductors, instead of the standard symbols -- minor but irritating. The introductory chapters are somewhat awkward and repetitive, but most readers will already be familiar with the problems of power use in portable devices (that's why they are reading the book), so they don't really need this material anyway.

Sealed Lead Acid.Nickel Cadmium.Lithium Ion.How do you balance battery life with performance and cost?This book shows you how!Now that "mobile" has become the standard, the consumer not only expects mobility but demands power longevity in wireless devices. As more and more features, computing power, and memory are packed into mobile devices such as iPods, cell phones, and cameras, there is a large and growing gap between what devices can do and the amount of energy engineers can deliver. In fact, the main limiting factor in many portable designs is not hardware or software, but instead how much power can be delivered to the device. This book describes various design approaches to reduce the amount of power a circuit consumes and techniques to effectively manage the available power.Power Management Advice On:.Low Power Packaging Techniques.Power and Clock Gating.Energy Efficient Compilers.Various Display Technologies.Linear vs. Switched Regulators.Software Techniques and Intelligent Algorithms* Addresses power versus performance that each newly developed mobile device faces* Robust case studies drawn from the author's 30 plus years of extensive real world experience are included* Both hardware and software are discussed concerning their roles in power

Wi-Fi (802.11) Network Handbook Review

Wi-Fi (802.11) Network Handbook
Average Reviews:

(More customer reviews)
Covers several areas which are not found in a lot of other books. However, at many places, it assumes that the reader has some basic knowledge. Completely lacks illustrations, examples, figures. The writing style is very boring - paragraph after paragraph without any structure to these. The information presented is definitely good and useful - but you gotta keep yourself awake !
All in all, I would NOT receommend this to anybody as a first book. I began with Jim Geir's book, and found that very good begin with. Actually a lot of the examples, figures in that book helped me understand many of the concepts mentioned in this book (sometimes in even greater detail). If the authors could improve upon the boring writing style and add some pictures to explain the concepts better - this book would be much better.

The Radio Amateur's Satellite Handbook (Radio Amateur's Library;, Publication No. 232) Review

The Radio Amateur's Satellite Handbook (Radio Amateur's Library;, Publication No. 232)
Average Reviews:

(More customer reviews)
This book is essential for anyone wanting to work with the Amateur Satellites. It covers the history of various projects, explains the modes of operation, and shows the equipment needed to talk with the birds. Like all the ARRL books, it is easy to follow and clearly written. The only problem I have with the book is that it hasn't been updated since 1997. It doesn't have good information on some of the newer spacecraft. As an example, it talks about the soon to be launched Phase 3D satellite rather than talking about the now orbiting AO-40 (ex Phase 3D) and some of the problems it is having. Still, the technology and techniques are very valid and good for anyone wishing to work with space communications.
In case your are thinking this is difficult to start in, I've had success transmitting to and receiving from the International Space Station using just a handheld transceiver (Kenwood TH-D7A) and either an attic mounted or handheld directional antenna. I've also heard voice from (but not transmitted to) the OSCAR 14 satellite with this same setup. You don't need an equipment setup to rival NASA in order to start with the aspect of the Amateur Radio hobby.

Designing Audio Power Amplifiers Review

Designing Audio Power Amplifiers
Average Reviews:

(More customer reviews)
When I heard that Bob Cordell had written a book on audio power amp design, I advance-ordered it immediately. Everything I'd seen of his work over the years had been eminently coherent and elegantly conveyed. The book arrived today and is well worth the wait.
I'm going to have to be careful about how much time I spend with this, as it could easily keep me up into the wee hours and lead to an impractical day following. But everything I've sampled is accurate, concise, and a pleasure to read. Much like Floyd Toole's recent magisterial tome, Sound Reproduction, Cordell calmly but decisively demolishes flawed audio mythology at every turn. Part 5, toward the end, is itself well-worth the price of admission. The discussion on negative feedback in particular is recommended.
But the book is not all about skewering shibboleths, and dipping into to earlier chapters reveals a keen and compassionate ability to convey crucial insights into real design. The balance between the maths, simulation results, and real-world experience is well-wrought. Again, I've not read but a fraction, but the flavor comes through readily from all of the excerpts I've perused.
As well, the book appears to be astonishingly typo-free. There must be a few, but I haven't found any yet.
Having heard directly from Toole how arduous the production of his book was, the fights with incompetent editors and so forth, and the negligible compensation he's receiving, I am mightily impressed with this book, and thank Bob Cordell for expending the enormous effort it has doubtless required. And I sense a fundamental decency about the man, somehow.
Very highly recommended.

AAA and Network Security for Mobile Access: Radius, Diameter, EAP, PKI and IP Mobility Review

AAA and Network Security for Mobile Access: Radius, Diameter, EAP, PKI and IP Mobility
Average Reviews:

(More customer reviews)
If you're looking for an in depth book on AAA and it's associated algorithms, there's no match for this book. Much as I wish I was wrong and that I could replace the book I borrowed from my friend with a cheaper book, I'm afraid I'm about to be forced to shell out the [...] on AAA. And I'm only going to need it as an intermittent reference. There's no math (at least no Greek), but many of the algorithms used to underpin the subject are explained concisely and clearly. It's simply well written and more informative than anything else on the market. I'm a sales engineer and this book was written on the ideal level for me. Technical enough but also abstract enough. Good work sir!

This is a solid and well-written book for beginner and intermediate types.
I pre-orderd this book because I like Peachpit's books and I had heard so much about podcasting that I thought I'd better 'get in the game'.
I was pleasantly surprised with this book. The author goes into detail about what podcasts are, where they came from, and then each of three chapters explain how to get and listen to podcasts as well as create and publish them.
An easy read that's well put together. Hopefully this review is helpful to others.

Web Geek's Guide to the Android-Enabled Phone
Average Reviews:

(More customer reviews)
Web Geek's Guide to the Android-Enabled Phone covers Android 1.5. Since the average person has no clue what an Android-Enabled phone is, the book starts off explaining in plain English the connection between this technology and Google. Essentially, the thought is that phones are fast becoming mini-computers. Soon, your phone will be your office without an office. This need will require better methods of connecting to the Internet and flexible ways for users to get/use/create the applications that they need to do their jobs.
In this way, T-Mobile is heavy on Internet based access. It also allows the user to create or adapt applications to suit individual needs. While this aspect might be a bit beyond most users, it is a step in the right direction.
