Book SynopsisTrade ReviewPraise for Eccentric Orbits: Named one of the “Top 10 Nonfiction Books of 2016” and one of the “20 Books That Defined Our Year” by the Wall Street Journal Named a Book of the Year 2016 by the Economist An Amazon Best Book of the Month A Hudson Booksellers’ Best Book of 2016 (Best Business Interest) “Engaging and ambitious . . . Eccentric Orbits is maximalist nonfiction, 500 pages of deep reporting put forward with epic intentions . . . a panoramic narrative, laced with fine filigree details, that makes for a story that soars and jumps and dives and digresses . . . [A] big, gutsy, exciting book.”—Wall Street Journal “Those with visions of vast satellite communications networks dancing in their heads would do well to read John Bloom’s new book on [Iridium] . . . Bloom . . . tells this story well . . . He does a good job of explaining the technology and the importance of the inventors who made the technology possible.”—Washington Post “Think of Final Cut, Steven Bach’s gripping account of the notorious movie disaster ‘Heaven’s Gate.’ Or The Smartest Guys in the Room, Bethany McLean and Peter Elkind’s chronicle of the collapse of Enron, and The Big Short, Michael Lewis’ tale of the cratering of the national economy. Eccentric Orbits . . . is a tale of ham-fisted management that’s lively enough to invite comparisons to those modern classics.”—Los Angeles Times “An exhaustive account . . . Eccentric Orbits not only offers good corporate drama, but is an enlightening narrative of how new communications infrastructures often come about: with a lot of luck, government help and investors who do not ask too many questions.”—Economist “Eccentric Orbits is a story rich in larger-than-life characters, including shady Cold War operatives and warrior-like Motorola executives . . . Bloom gives a wonderful sense of what an engineering marvel Iridium was.”—Bethany McLean, Strategy + Business (Best Business Books 2016) “An inspiring history as well as an effective business thriller . . . Bloom argues convincingly that creating and then saving Iridium was one . . . desperately difficult—and brilliant—achievement.”—New Scientist “Extensive . . . Sprawling . . . A detailed and entertaining history of the rise, fall, and rebirth of Iridium.”—Space Review “A good read.”—Marketplace “Highly engaging . . . Check it out.”—News Tribune “A prize-worthy example of the investigative genre . . . [Eccentric Orbits] has conflict and triumph on a Wagnerian scale . . . John Bloom has achieved in Eccentric Orbits an admirable balance of the human and the technological in what is at heart an age-old tale of one man’s triumph against apparently insuperable odds.”—Literary Review “An outstanding read . . . [An] inspiring story . . . Highly recommended.”—ATC Reform News “Eccentric Orbits does for the 1990s birth of the satellite phone industry what Tracy Kidder’s Soul of a New Machine did for the next-generation computer business. It’s a wild story . . . Funny, informative, exciting . . . A sprawling masterpiece of history and reporting.”—Shelf Awareness “Spellbinding . . . A tireless researcher, Bloom delivers a superlative history . . . A tour de force.”—Kirkus Reviews (starred review) “Eccentric Orbits is a remarkable work. I had known about Iridium but not about its fascinating history. John Bloom’s writing style is attractive and the level of detail is astonishing. This was a page-turner for me!”—Vint Cerf, Chief Internet Evangelist, Google “Interested in giant, head-scratching miscalculations by a great American company? The power of one man to rescue the world’s biggest deployment of low-earth satellites? A place where genius engineering meets a total lack of common sense? Then John Bloom’s book about Motorola’s multibillion-dollar debacle, Iridium, is for you. Eccentric Orbits is both a novelistic thriller and a cautionary tale, a page-turner about a reach for the heavens and a business primer on a near-fatal fall back to the earth.”—Julian Guthrie, author of The Billionaire and The Mechanic “John Bloom’s Eccentric Orbits, which tells the story of one of the most ambitious projects in the history of technology, is the most compelling book I have read in a long while. Bloom somehow coaxed the deepest thoughts and darkest secrets out of many satellite engineers, skeptical VCs, business royalty, inner-city tycoons, Italian marketers, Russian rocket launchers, Arabian princes, corporate CEOs, African leaders, Washington insiders, insurance giants, Pentagon brass, government lifers, politicians, and frustrated bankruptcy judges. This is a masterpiece of research and storytelling. If not for Bloom, one of the greatest stories of American ingenuity and bullheadedness would still lie scattered in thousands of documents and the memories of those who lived it.”—Gary Kinder, author of Ship of Gold in the Deep Blue Sea “This is a monumental piece of non-fiction, not just for the breadth and depth of the research, but for its audacity: Bloom seeks to make technology and marketing and high finance dramatic and funny and instructive of the human condition—and succeeds. Until I read this, I had always assumed that my cell phone was created by something like spontaneous combustion; like one day, it just appeared between my right hand and my ear, as if it had always belonged there. Bloom has given all of us—all billions of us—the back story on it, and what a strange, tangled, convoluted, fairly hilarious one it is.”—Jim Atkinson, Texas Monthly contributing editor “Build a better mousetrap, and the world will erect every possible obstacle to its success. That’s the sobering lesson of John Bloom’s book on the progress of a reliable, cheap, encrypted, worldwide mobile phone system to supermarket shelves. The exhilarating lesson is that it can be done if you have visionary geeks, hard-boiled veterans, retired capitalists, and the occasional eccentric rebellious bureaucrat determined to do it. This is high scientific journalism, exciting business journalism, and a rattling good tale. It even includes Nazis.”—John O’Sullivan, author of The President, the Pope, and the Prime Minister: Three Who Changed the World “Impeccably researched, and in smooth, easy prose, John Bloom interweaves fascinating historical trivia about the space race, satellites, and global communications with detail-filled personality snapshots and cringingly revealing, often disturbingly humorous, insights about the many ways big business can shoot itself in the foot.”—John Brewer, former president and editor-in-chief, New York Times Syndicate and News Service “Pacy [and] . . . worth reading, not just for the wild ride that involves secretive Saudi sheikhs, plucky terrorists, never-say-die businessmen and Bill Clinton, but also as a reminder of how vast business can be vastly dumb . . . A thrilling boom-to-boom corporate drama.”—Sunday Times (UK) “John Bloom’s account of the Iridium satellite network is more than a ripping read, it is both a commentary on the way we do technology today and a reminder of Friedrick Hayek’s observation that presumed experts and planners are the last people you want picking winners. A tale well told is a thing of delight, and John Bloom’s Eccentric Orbits: The Iridium Story does not fail.”—Quadrant (Australia) “Riveting . . . I’ve never used the term ‘tour de force’ in a book review before, but if it ever belonged in one, it is this review of Eccentric Orbits.”—800-CEO-READ

Taylor & Francis Ltd Hybrid Encryption Algorithms over Wireless
Book SynopsisThis book presents novel hybrid encryption algorithms that possess many different characteristics. In particular, Hybrid Encryption Algorithms over Wireless Communication Channels, examines encrypted image and video data for the purpose of secure wireless communications. A study of two different families of encryption schemes are introduced: namely, permutation-based and diffusion-based schemes. The objective of the book is to help the reader selecting the best suited scheme for the transmission of encrypted images and videos over wireless communications channels, with the aid of encryption and decryption quality metrics. This is achieved by applying number-theory based encryption algorithms, such as chaotic theory with different modes of operations, the Advanced Encryption Standard (AES), and the RC6 in a pre-processing step in order to achieve the required permutation and diffusion. The Rubik's cube is used afterwards in order to maximize the number of permutations.TransmisTrade Review“ In this clearly written book, Shaheen studies methods of encrypting images and video for transmission over wireless communication systems, and methodically demonstrates several encryption algorithms. This text will certainly be of interest to graduate students and researchers in the field of wireless communications.”— J. M.

Book SynopsisOffers an up-to-date description of modern multifunctional antenna systems and microwave components Compact multifunctional antennas are of great interest in the field of antennas and wireless communication systems, but there are few, if any, books available that fully explore the multifunctional concept. Divided into six chapters, Compact Multifunctional Antennas for Wireless Systems encompasses both the active and passive multifunctional antennas and components for microwave systems. It provides a systematic, valuable reference for antenna/microwave researchers and designers. Beginning with such novel passive components as antenna filters, antenna packaging covers, and balun filters, the book discusses various miniaturization techniques for the multifunctional antenna systems. In addition to amplifying and oscillating antennas, the book also covers design considerations for frequency- and pattern-reconfigurable antennas.

John Wiley & Sons Inc Wireless Connectivity
Book SynopsisWireless Connectivity: An Intuitive and Fundamental Guide Wireless connectivity has become an indispensable part, a commodity associated with the way we work and play. The latest developments, the 5G, next-generation Wi-Fi and Internet of Things connectivity, are the key enablers for widespread digitalization of practically all industries and public sector segments. This immense development within the last three decades have been accompanied by a large number of ideas, articles, patents, and even myths. This book introduces the most important ideas and concepts in wireless connectivity and discusses how these are interconnected, whilst the mathematical content is kept minimal. The book does not follow the established, linear structure in which one starts from the propagation and channels and then climbs up the protocol layers. The structure is, rather, nonlinear, in an attempt to follow the intuition used when one creates a new technology to solve a certain problem. The target audience is: Students in electronics, communication, and networkingWireless engineers that are specialized in one area, but want to know how the whole system works, without going through all the details and mathComputer scientists that want to understand the fundamentals of wireless connectivity, the requirements and, most importantly, the limitationsEngineers in energy systems, logistics, transport and other vertical sectors that are increasingly reliant on wireless technologyTable of ContentsForeword xv Acknowledgments xix Acronyms xxi 1 An Easy Introduction to the Shared

John Wiley & Sons Inc Evaluation of HSDPA to LTE
Book SynopsisThis book explains how the performance of modern cellular wireless networks can be evaluated by measurements and simulations With the roll-out of LTE, high data throughput is promised to be available to cellular users. In case you have ever wondered how high this throughput really is, this book is the right read for you: At first, it presents results from experimental research and simulations of the physical layer of HSDPA, WiMAX, and LTE. Next, it explains in detail how measurements on such systems need to be performed in order to achieve reproducible and repeatable results. The book further addresses how wireless links can be evaluated by means of standard-compliant link-level simulation. The major challenge in this context is their complexity when investigating complete wireless cellular networks. Consequently, it is shown how system-level simulators with a higher abstraction level can be designed such that their results still match link-level simulations.

Book SynopsisThe world is going mobile at an astounding pace. Estimates show 80 percent of global Internet access will take place through mobile devices by 2016. Smartphones, tablets, and handheld devices have reshaped communications, the global economy, and the very way in which we live. The revolution is an electronic nirvana: for the first time in human history we have sophisticated digital applications to help us learn, access financial and health care records, connect with others, and build businesses. But the one trillion dollar mobile industry is still relatively young. Leaders in both the public and private sectors need to figure out how to apply mobile technologies or mobile devices to optimize education, health care, public safety, disaster preparedness, and economic development. And the ever-expanding mobile frontier presents new challenges to law, policy, and regulations and introduces new tensions; one person''s idea of cautious deliberation can be another''s idea of a barrier

Duke University Press The Undersea Network
Book SynopsisNicole Starosielski examines undersea communication cable network, bringing it to the surface of media scholarship and making visible the "wireless" network's materiality. She argues that the network is inextricably linked to historical and political factors and that it is precarious, rural, aquatic, territorially entrench and semi-centralized.Trade Review“Starosielski offers a crucial intervention into theoretical conceptualizations of communications infrastructure. . . . This rich text also has profound implications for how citizens in an always-networked society and economy understand our lived realities. The Undersea Network makes us reconsider the ‘wirelessness’ of our world by admonishing us consider it in terms of its peculiar and ongoing connectedness to geographies, cultures, and politics.” -- Sara Rodrigues * PopMatters *“[A] fascinating book that is part history, part travelogue and part socio-economic memoir. . . .

[T]his book is a good read for anyone broadly interested in geography or communications.” -- Eva Amsen * Hakai Magazine *“A fascinating cultural assessment of global undersea cable networks that carry most of the world's trans-ocean Internet traffic. … Great stuff!” -- Christopher Sterling * Communication Booknotes Quarterly *"Overall, the book brilliantly brings together the global metanarrative of mass communication with the local, material, and relatively immobile specificities of this undersea network.... Starosielski is extremely successful in rewiring our wireless imaginaries of a networked world. The depth and breadth of the fieldwork conducted is noteworthy as is the production of the book itself, which contains a plethora of images, graphics, and maps." -- Rachael Squire * Transfers *"The multistranded analysis developed in the book provides a rewarding account that blends cultural history with investigative ethnography and along the way takes us to remote sites in Hawaii, Tahiti and Guam. Most importantly, Starosielski brings the infrastructure of undersea cable systems back into visibility, showing us in vivid ways what makes global communications possible." * European Journal of Communication *"The Undersea Network succeeds in introducing an environmental consciousness into one’s imagination of digital networks and the ecological, political, financial, place-based contingencies that support, interfere with and maintain our global telecommunications system. It makes cables salient. ... The Undersea Network is required reading for students of media and network archaeology, communication educators, political and environmental scientists, the history of technology discipline, and readers within the cable industries and government." -- Emily Goodmann * International Journal of Media & Cultural Politics *"If you have ever wondered why infrastructure has suddenly become a buzzword in cultural anthropology and science and technology studies, then follow the signal. That is precisely what The Undersea Network does, brilliantly redeeming the promise of multi-sited fieldwork methods to highlight the connections and disconnection–historical and present-day–among far-flung people and places.... For anyone with an interest in Pacific studies, this book has plenty to ponder." -- Robert J. Foster * Journal of Pacific History *"[A]n enthralling read for anybody with an interest in telecoms infrastructure and the way that it is presented in the media." -- Mike Conradi * Telecommunications Policy *"This is a fascinating and deeply geographical piece of media scholarship.Starosielski’s book is remarkably successful in demonstrating that the unstable materiality of the infrastructures it describes matters in all kinds of sometimes contradictory ways to those who construct these infrastructures, to those they connect, and to those who remain at a distance from their connective capacities." -- Derek P.

Duke University Press The Undersea Network
Book SynopsisIn our 'wireless' world it is easy to take the importance of the undersea cable systems for granted, but the stakes of their successful operation are huge, as they are responsible for carrying almost all transoceanic Internet traffic. In The Undersea Network Nicole Starosielski follows these cables from the ocean depths to their landing zones on the sandy beaches of the South Pacific, bringing them to the surface of media scholarship and making visible the materiality of the wired network. In doing so, she charts the cable network''s cultural, historical, geographic and environmental dimensions. Starosielski argues that the environments the cables occupy are historical and political realms, where the network and the connections it enables are made possible by the deliberate negotiation and manipulation of technology, culture, politics and geography. Accompanying the book is an interactive digital mapping project, where readers can trace Trade Review“Starosielski offers a crucial intervention into theoretical conceptualizations of communications infrastructure. . . .

[T]his book is a good read for anyone broadly interested in geography or communications.” -- Eva Amsen * Hakai Magazine *“A fascinating cultural assessment of global undersea cable networks that carry most of the world's trans-ocean Internet traffic. … Great stuff!” -- Christopher Sterling * Communication Booknotes Quarterly *"Overall, the book brilliantly brings together the global metanarrative of mass communication with the local, material, and relatively immobile specificities of this undersea network.... Starosielski is extremely successful in rewiring our wireless imaginaries of a networked world. The depth and breadth of the fieldwork conducted is noteworthy as is the production of the book itself, which contains a plethora of images, graphics, and maps." -- Rachael Squire * Transfers *"The multistranded analysis developed in the book provides a rewarding account that blends cultural history with investigative ethnography and along the way takes us to remote sites in Hawaii, Tahiti and Guam. Most importantly, Starosielski brings the infrastructure of undersea cable systems back into visibility, showing us in vivid ways what makes global communications possible." * European Journal of Communication *"The Undersea Network succeeds in introducing an environmental consciousness into one’s imagination of digital networks and the ecological, political, financial, place-based contingencies that support, interfere with and maintain our global telecommunications system. It makes cables salient. ... The Undersea Network is required reading for students of media and network archaeology, communication educators, political and environmental scientists, the history of technology discipline, and readers within the cable industries and government." -- Emily Goodmann * International Journal of Media & Cultural Politics *"If you have ever wondered why infrastructure has suddenly become a buzzword in cultural anthropology and science and technology studies, then follow the signal. That is precisely what The Undersea Network does, brilliantly redeeming the promise of multi-sited fieldwork methods to highlight the connections and disconnection–historical and present-day–among far-flung people and places.... For anyone with an interest in Pacific studies, this book has plenty to ponder." -- Robert J. Foster * Journal of Pacific History *"[A]n enthralling read for anybody with an interest in telecoms infrastructure and the way that it is presented in the media." -- Mike Conradi * Telecommunications Policy *"This is a fascinating and deeply geographical piece of media scholarship.Starosielski’s book is remarkably successful in demonstrating that the unstable materiality of the infrastructures it describes matters in all kinds of sometimes contradictory ways to those who construct these infrastructures, to those they connect, and to those who remain at a distance from their connective capacities." -- Derek P.
