Book Description
As the telecommunication and information field expands and becomes more varied, so do publications about these technologies and industries. This book is a first attempt to provide a general guide to that wealth of English-language publications -- both books and periodicals -- on all aspects of telecommunication. It is a comprehensive, evaluative sourcebook for telecommunications research in the United States that brings together a topically-arranged, cross-referenced, and indexed volume in one place. The information provided is only available by consulting a succession of different directories, guides, bibliographies, yearbooks, and other resources. On the one hand, it is a directory that describes in detail the major entities that comprise the American telecommunication research infrastructure including federal and state government offices and agencies, and private, public, and corporate research institutions. On the other hand, it is a bibliography that identifies and assesses the most important and useful reference and critical resources about U.S. telecommunication history, technology, industry and economics, social applications and impacts, plus policy, law and regulations, and role in the global telecommunication marketplace. No existing guide covers all of these aspects in the depth and detail of this volume.

Book Description
Faxed is the first history of the facsimile machine—the most famous recent example of a tool made obsolete by relentless technological innovation. Jonathan Coopersmith recounts the multigenerational, multinational history of that device from its origins to its workplace glory days, in the process revealing how it helped create the accelerated communications, information flow, and vibrant visual culture that characterize our contemporary world. Most people assume that the fax machine originated in the computer and electronics revolution of the late twentieth century, but it was actually invented in 1843. Almost 150 years passed between the fax’s invention in England and its widespread adoption in tech-savvy Japan, where it still enjoys a surprising popularity. Over and over again, faxing’s promise to deliver messages instantaneously paled before easier, less expensive modes of communication: first telegraphy, then radio and television, and finally digitalization in the form of email, the World Wide Web, and cell phones. By 2010, faxing had largely disappeared, having fallen victim to the same technological and economic processes that had created it. Based on archival research and interviews spanning two centuries and three continents, Coopersmith’s book recovers the lost history of a once-ubiquitous technology. Written in accessible language that should appeal to engineers and policymakers as well as historians, Faxed explores themes of technology push and market pull, user-based innovation, and "blackboxing" (the packaging of complex skills and technologies into packages designed for novices) while revealing the inventions inspired by the fax, how the demand for fax machines eventually caught up with their availability, and why subsequent shifts in user preferences rendered them mostly passé.

Book Description
Towards location aware mobile ad hoc sensors A Systems Engineering Approach to Wireless Information Networks The Second Edition of this internationally respected textbook brings readers fully up to date with the myriad of developments in wireless communications. When first published in 1995, wireless communications was synonymous with cellular telephones. Now wireless information networks are the most important technology in all branches of telecommunications. Readers can learn about the latest applications in such areas as ad hoc sensor networks, home networking, and wireless positioning. Wireless Information Networks takes a systems engineering approach: technical topics are presented in the context of how they fit into the ongoing development of new systems and services, as well as the recent developments in national and international spectrum allocations and standards. The authors have organized the myriad of current and emerging wireless technologies into logical categories: * Introduction to Wireless Networks presents an up-to-the-moment discussion of the evolution of the cellular industry from analog cellular technology to 2G, 3G, and 4G, as well as the emergence of WLAN and WPAN as broadband ad hoc networks * Characteristics of Radio Propagation includes new coverage of channel modeling for space-time, MIMO, and UWB communications and wireless geolocation networks * Modem Design offers new descriptions of space-time coding, MIMO antenna systems, UWB communications, and multi-user detection and interference cancellation techniques used in CDMA networks * Network Access and System Aspects incorporates new chapters on UWB systems and RF geolocations, with a thorough revision of wireless access techniques and wireless systems and standards Exercises that focus on real-world problems are provided at the end of each chapter. The mix of assignments, which includes computer projects and questionnaires in addition to traditional problem sets, helps readers focus on key issues and develop the skills they need to solve actual engineering problems. Extensive references are provided for those readers who would like to explore particular topics in greater depth. With its emphasis on knowledge-building to solve problems, this is an excellent graduate-level textbook. Like the previous edition, this latest edition will also be a standard reference for the telecommunications industry.
