(More customer reviews)In his last public speech, noted Nobel Prize winner and leading Manhattan Project member Isidor Isaac Rabi said, "Science, for its progress, its understanding and so on, depends so much on truth and on clarity. And the question is: Are we living in a society where truth and clarity are an important element of our culture?" We placed Rabi's thought-provoking statement on the third page of our book because it so clearly expresses what we, as authors, strove to accomplish.
In any technical book, nothing is more important than accurate, factual information, or in Rabi's words - technical truth. Unfortunately, particularly in introductory books, inadequate scope, oversimplification, and shallow or incorrect definition and explanations of key technologies deny readers the factual understanding they invest their time to learn.
And, if accuracy is paramount, clarity ranks a close second in terms of desirable introductory technical book attributes. Books comprehensible only by scholars or technologists with existing in-depth knowledge and mathematical prowess, are of little help to business people and individuals that make up the majority of those who must use today's advanced technologies.
The principal objective of our updated book remains to provide a reliable, comprehensive introduction and insightful perspectives into all modern telecommunications services and underlying technologies. A second objective-no less important than the first-is to employ a presentation style easily understood by government and commercial telecommunications planners, managers, users, and professionals who do not have the time to sift through multiple publications, complex formulae, and mathematics only to be forced to draw their own conclusions regarding technology, performance, and market alternatives.
We treat all important telecommunications services and technologies, but the quantity of information is limited to that needed for complete understanding. In addition, rather than just addressing topics individually, expert interpretations provide a valuable grasp of "bottom line" relationships among emerging services, technologies, and industry standards.
Simplicity of presentation style does not sacrifice the ability to familiarize readers with industry terminology and essential concepts-which is often the case with introductory material. To accomplish this, we systematically present basic definitions as part of explanations of larger concepts. This equips readers not only with terminology, but also with rationale behind real-world applications, a tremendous advantage for thorough understanding and memory retention.
In this respect, perhaps the feature of the original "The McGraw-Hill Telecommunications Factbook" contributing most to its popularity and effectiveness is the rich array, quality and clarity of its figures. Using over 240 figures, the new book goes far beyond simply identifying and defining panoplies of services and technologies. Inimitable technology taxonomy charts form the basis for uncommonly clear explications that fully apprise readers of essential differences and the practical advantages among alternative technology options.
The appearance of such a book could not have been more timely. The mushrooming rate of introduction of new technologies has created an enormous need for technically literate employees and a critical shortage of such workers in the United States. Since current laws limit the use of immigrants, many businesses are pursuing aggressive US recruitment and intensive training programs. Because many of the rapidly appearing new technologies are more complex than their predecessors, new and more efficient learning techniques and tools are a necessity. In this regard, we honestly believe our book has established new plateaus of pedagogical excellence.
We are proud of the fact that readers with no prior engineering or mathematical backgrounds, with only vague perceptions of what analog or digital electronic signals might be, can pick up our book, and gain a practical appreciation of telecommunications fundamentals; acquire a familiarity with industry standard terminology; and end up with working understandings of complex capabilites like DS1/DS3 (T1/T3) asynchronous multiplexing; SONET synchronous multiplexing; modulation schemes used in some of the most advanced digital subscriber link (DSL) and cellular wireless services; insights into the most successful and valuable Internet technologies; and, countless other pivotal telecommunications technologies that can bolster the success of nearly every enterprise, and indeed all industrialized nations.
We believe that imparting substantive explanations of telecommunications technologies is markedly different than the practice of simply heralding, "headline-grabbing", "bell and whistle" features of new technologies - which is all that is offered in superficial introductory manuscripts.
But, beyond salutary effects that telecommunications has on companies or nations, are more personal benefits. In fact, telecommunications is the technology most directly related to man's highest faculty and his most sublime activities: namely, his acquisition of information, the thoughts by which he interprets and postulates new ideas and conclusions, and the exchange of his thoughts with others to refine and iterate the process. There is no question that telecommunications greatly augments both the potential quality and the timeliness of these powerful and uniquely human abilities.
In truth, what modern agricultural and grocery-product transportation and distribution technologies do for men's stomachs is analogous to what telecommunications technologies do for men's minds. And with the pace of new technology advancement approaching the "speed of light through fiber cables", the possibilities are exciting and perhaps unbounded. Acquire the book and read on - the fun is just beginning!
