Applied Data Communications: A Business-Oriented Approach Review

Applied Data Communications: A Business-Oriented Approach

I just finished a course on data communications at a local college. Since I knew absolutely nothing about the topic. I had nowhere to go but up. Mr Goldman's book is very readable and is chock filled with charts, checkoff lists and such that I will use when I get into the IT field. His objective to get the reader to think in terms of applying the material rather than memorizing it. He suceeds. Does he have any other related works out there? I'll buy them.

Anywhere: How Global Connectivity is Revolutionizing the Way We Do Business Review

Anywhere: How Global Connectivity is Revolutionizing the Way We Do Business
Average Reviews:

(More customer reviews)
This book hits the pluses and provides an optimistic view of emerging connectivity, but it's weak on addressing the downsides and reality of it. So, I'll begin by pointing out a few things this book overlooks. Then I'll sum up what it addresses.
What the author doesn't tell you
First, there's the productivity cost. It's huge. I used to carry a cell phone everywhere. Now, I don't use one. In fact, I rarely answer my regular telephone. Sometimes, I unplug it for hours at a time.
I don't like being interrupted, especially when I'm trying to do something productive. A business that inflicts constant connectivity on its employees has a highly distracted workforce. Ms. Green makes it sound as though the Twitter-averse among us are like the e-mail-averse of times past. But this is an apples to oranges comparison.
Second, there's the attention cost. E-mail is asynchronous. Texting and tweeting are "immediate response" activities. Can anyone who's chained to a frequently-interrupting device really pay attention to any worthwhile activity? Any technology that interrupts you simply because it can is just too costly, unless you aren't the kind of person who does anything that matters.
Third, there's the subscription cost. If you have a mobile data plan, ask yourself what you are really getting for all that money. If it's just interruptions and the ability to send/receive throwaway photos, then it might not be all that good. For a business, a mobile data plan may be essential. But how many people are paying $99 a month or more for something that they probably would not miss if they stopped using it? If you have one of these plans, is it making your life better or is it an addiction?
A fourth problem is the devices are insanely small. It's not convenient to carry around a pair of reading glasses just so you can take a phone call. I have a PocketPC that I don't use because I can't read the screen in daylight at all, and indoors I need reading glasses to read it. The manufacturer's solution to this problem was to make the next generation even smaller.
Ms. Green also indicates that older folks just don't get it and will eventually be replaced by their hipper, more tech-savvy younger counterparts through retirement. What she overlooks is the reason older people are far less adoptive of this technology than younger people is presbyopia. We have reams of data showing that humans need larger fonts as we age. That's just the way it is. When the devices are explicitly designed for people under 25 and consequently exclude people beyond a certain age, the adoption rates by age are quite predictable.
So, we have some huge barriers to "anywhere" connectivity. For the vast majority of us, it just isn't workable. Does that mean we aren't going to see vastly increased connectivity that is far more mobile than today? No. But it does mean the connectivity needs to serve the users rather than make them servile to it, and it must not rely on unreadable screens or gadgets that seem designed expressly to annoy the users. Until those requirements are met, connectivity will fall far short of its potential.
What the author does tell you
Ms. Green addresses this topic of ubiquitous connectivity in 250 pages. The book consists of four Parts:
Part I: Welcome to Anywhere. This consists of three chapters, and in these she outlines and describes the "Anywhere Revolution." I think these three chapters give the reader a good feel for where we're eventually heading and why.
Part II: The Anywhere Consumer. This consists of three chapters, and in these she presents four basic category of consumer. I'm not sure about these categories. I have fit into three of them at one time or another, and don't see where I fit presently.
I don't have her research data, but it seems to me there is a fifth category that has a higher population than the other four combined. I call it "Annoyed Consumer." We get tired of Windows memory problems, crap that pops up when you're trying to type, screens we can't read, interruptions we don't want, high bills from service providers, and just a host of usability issues. We are not amused.
Part III: The Anywhere Enterprise. This consists of two chapters. I think it needs a third. Ask hiring managers about what bugs them today, and you are going to hear "Kids texting during interviews." There is a difference between productive connectivity and counterproductive connectivity. The author doesn't explore this, at all. A chapter on how businesses can properly address this difference seems essential to me.
For example, do you really want your sales people texting during a sales call instead of focusing on that customer? Of course not. But at the same time, it would be wonderful for a sales person to be able to answer a question for the customer to close the sale. Shortening the sales cycle can accelerate revenue, and that's generally a good thing. Insulting a customer through rude behavior, however, is generally not advantageous. The rudeness factor is a big problem with today's so-called "hip generation" and it's something business needs to be able to rechannel into positive behaviors.
Part IV: Profiting from Anywhere consists of four chapters. In these chapters, the author basically says you need to max out your anywhere quotient as fast as you can. This isn't quite the way things really are. Companies that still operate on paper processes and/or have very low connectivity do need to modernize. And some companies that are current with technology, processes, and connectivity do need to be working on upgrading as the bar rises. But these are the outliers on the bell curve.
Most of us would do well to assess, based on the information presented here, and plan for staying reasonably current. I think this book is helpful toward this purpose, because it gives a good view of what is coming. But the real challenge for profit-minded businesses is going to be properly restraining connectivity to the scope of the business.
A couple of years ago, we were in the midst of blogomania. The big advice was that businesses must blog or die. Following this advice has proven to be a colossal waste of resources for most businesses, and in 2010 this realization even dawned on some business journalists. Blogs and banality have come to be synonymous, with few exceptions.
Facebook appears to have peaked out and to now be declining in its influence and popularity. People can take only so much blather, meaningless detail, and banality before wanting to have a life.
Similarly, companies can divert only so many resources to nonproductive activities before seeing their customer service, productivity, and profitability slide. The issue isn't one of having enough connectivity. It's one of having the right connectivity.
A solution seeking a problem generally does more harm than good to a business. If a business has a problem that specific types of connectivity can solve, then it needs to look at adopting those kinds of connectivity. And quickly, before the problems metastasize. But a business must also look at the potential risks involved with that adoption and develop a plan that properly addresses those risks. Otherwise, the cure might be worse than the disease.
The SWOT analysis (Strengths, Weaknesses, Opportunities, and Threats) is a core business tool for evaluating new ventures, proposed projects, and other things a business might wish to evaluate. I think if the author had used this framework for Part III and Part IV, the book would have been far more useful.
An important point the author drives at again and again is every business must look at the connectivity issues that are here now and the ones that are emerging. I think this book definitely helps identify and define many key issues in that arena.

Making Things Talk: Practical Methods for Connecting Physical Objects Review

Making Things Talk: Practical Methods for Connecting Physical Objects
Average Reviews:

(More customer reviews)
When I first heard about this book, I assumed it was about projects for speech synthesis. When I read the details on the publisher's site I was somewhat disappointed - talking meant communications in this case. However, I ordered it anyway and was quite delighted by the results. The book is well illustrated, well written, and contains 26 very interesting projects. If you are teaching networking to high schoolers or even to college students, these projects might make interesting case studies to drive home some of the points being studied.
There is one thing I would caution you on though. Don't expect the lead-you-by-the-hand electronics-heavy methodology of most other project books. This book - although apparently targeted at electronics hobbyists - goes into painstaking detail on hardware needed and assembly. However, it oddly assumes the reader doesn't need much coaching on the Processing programming language or PHP. Of course, this book would be an unwieldy tome if tutoring on those subjects were included, but just be warned that you'll need some outside sources if you are not already familiar with either of these languages. The following is the list of contents of the book along with the names and locations of the 26 included projects.
1. The Simplest Tools
2. The Simplest Network
Project 1 - Monski Pong
Project 2 - Wireless Monski Pong

Building electronic projects that interact with the physical world is good fun. But when devices that you've built start to talk to each other, things really start to get interesting. Through a series of simple projects, you'll learn how to get your creations to communicate with one another by forming networks of smart devices that carry on conversations with you and your environment. Whether you need to plug some sensors in your home to the Internet or create a device that can interact wirelessly with other creations, Making Things Talk explains exactly what you need. This book is perfect for people with little technical training but a lot of interest. Maybe you're a science teacher who wants to show students how to monitor weather conditions at several locations at once, or a sculptor who wants to stage a room of choreographed mechanical sculptures. Making Things Talk demonstrates that once you figure out how objects communicate -- whether they're microcontroller-powered devices, email programs, or networked databases -- you can get them to interact. Each chapter in contains instructions on how to build working projects that help you do just that. You will:

Make your pet's bed send you email
Make your own seesaw game controller that communicates over the Internet
Learn how to use ZigBee and Bluetooth radios to transmit sensor data wirelessly

Handbook of Mobile Communication Studies Review

Handbook of Mobile Communication Studies
Average Reviews:

(More customer reviews)
This is a book of thirty two independent chapters written by some of the leaders in mobile communication studies by MIT Press, a leader in ethnographic titles devoted to technology.
The chapters span research in countries and regions including Ghana, China, Mexico, Northern Africa, the Arab Gulf States, New Zealand, Japan, Singapore, Israel, India, the Philippines, Indonesia and South Korea. The editor, James E. Katz, heads the Center for Mobile Communication Studies at Rutgers University.
The focus is not on mobile technology, but how it is used by people based on primary research.
The authors are largely university researchers or researchers in mobile carrier labs. Included are well known mobile ethnographers Jan Chipchase and early prognosticators on technology adoption such as Harold Rheingold and Sherry Turkle.
Much of this type of research is conducted within companies with mobile business interests, and is never published. The value of the book is as a guide to university mobile research centers, who is publishing publicly in the field, in which journals, and at which conferences.
Every essay is fascinating, readable, and extensively footnoted.
The first section is Digital Divides and Social Mobility: studies of feature phone use in developing countries. The second is Sociality and Copresence: studies of dimensions of the always connected individual and group. The third section, Politics and Social Change includes specific studies on democracy, civil society and social change driven by individual and group use of mobile technology. The last section is Culture and Imagination: including studies of mobile gaming, courtship and family dynamics in India, music, and even mobile applications to spiritual mysticism in the Philippines.
I look forward to more books in this format on the topic, published every 2-3 years. Mobile society is a critical worldchanging topic, and moves quickly.

Ok, I admit I have not read it yet. But it's because I can't get my copy back! I loaned the book to the science teacher at my son's school, and asked her to take a look to see what she thought. She liked what she saw, and gave it to a 3rd grader who loves science to see if he liked it and could understand it. He did, so much so that he begged to keep it to finish! Clearly it's a hit! I bought another copy for the school to keep in the science class. And eventually, I and my 4th grader will get our copy back to read!

Their buzzes, beeps, bells, and tunes have disrupted countless classes, movies, and meals; public auditoriums now have signs posted prominently asking people to turn their cell phones off; cities such as Santa Fe have banned their use in automobiles. But these little connection gadgets have become ubiquitous because they are so useful many would blanch at the thought of losing their cell phone. Cell phones are useful because of the science, technology, and design that are blended to make them function.
In this work, authors Michele Sequeira and Michael Westphal help young people explore this now-commonplace, socially important gadget that connects today s youth with their friends. The underlying science and technologies, and some of the history that has influenced the development of cell phones, are discussed. Emphasis is given to building science and technology concepts through simple analogies with commonplace items and ideas.

For some reason I thought this would be a "direct from RF to baseband" OFDM receiver design book, including example circuitry, etc.. Instead it does not cover any RF modulation/demodulation issues, other than to show a block diagram including "RF TX" and "RF TX" (a typo, should be "RF RX"). English is choppy in spots, but completely understandable. If you are looking for lots of theory and diagrams concerning the many aspects of OFDM receiver design, this is a good book. If you are looking for anything hardware related, or even RF mod/demod issues, you will be disappointed.
