Available in PDF, EPUB and Kindle. Book excerpt: Long before the Arab Spring and its use of social media demonstrated the potent intersection between technology and revolution, the Mexican Revolution employed wireless technology in the form of radiotelegraphy and radio broadcasting to alter the course of the revolution and influence how political leaders reconstituted the government. Radio in Revolution, an innovative study of early radio technologies and the Mexican Revolution, examines the foundational relationship between electronic wireless technologies, single-party rule, and authoritarian practices in Mexican media. J. Justin Castro bridges the Porfiriato and the Mexican Revolution, discussing the technological continuities and change that set the stage for Lázaro Cárdenas's famous radio decree calling for the expropriation of foreign oil companies. Not only did the nascent development of radio technology represent a major component in government plans for nation and state building, its interplay with state power in Mexico also transformed it into a crucial component of public communication services, national cohesion, military operations, and intelligence gathering. Castro argues that the revolution had far-reaching ramifications for the development of radio and politics in Mexico and reveals how continued security concerns prompted the revolutionary victors to view radio as a threat even while they embraced it as an essential component of maintaining control.

Download or read book Software Defined Radio written by Walter H.W. Tuttlebee and published by John Wiley & Sons. This book was released on 2003-04-11 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Software defined radio (SDR) is one of the most important topics of research, and indeed development, in the area of mobile and personal communications. SDR is viewed as an enabler of global roaming and as a unique platform for the rapid introduction of new services into existing live networks. It therefore promises mobile communication networks a major increase in flexibility and capability. SDR brings together two key technologies of the last decade - digital radio and downloadable software. It encompasses not only reconfiguration of the air interface parameters of handset and basestation products but also the whole mobile network, to facilitate the dynamic introduction of new functionality and mass-customised applications to the user's terminal, post-purchase. This edited book, contributed by internationally respected researchers and industry practitioners, describes the current technological status of radio frequency design, data conversion, reconfigurable signal processing hardware, and software issues at all levels of the protocol stack and network. The book provides a holistic treatment of SDR addressing the full breadth of relevant technologies - radio frequency design, signal processing and software - at all levels. As such it provides a solid grounding for a new generation of wireless engineers for whom radio design in future will assume dynamic flexibility as a given. In particular it explores * The unique demands of SDR upon the RF subsystem and their implications for front end design methodologies * The recent concepts of the 'digital front end' and 'parametrization' * The role and key influence of data conversion technologies and devices within software radio, essential to robust product design * The evolution of signal processing technologies, describing new architectural approaches * Requirements and options for software download * Advances in 'soft' protocols and 'on-the-fly' software reconfiguration * Management of terminal reconfiguration and its network implications * The concepts of the waveform description language The book also includes coverage of * Potential breakthrough technologies, such as superconducting RSFQ technology and the possible future role of MEMS in RF circuitry * Competing approaches, eg all-software radios implemented on commodity computing vs advanced processing architectures that dynamically optimise their configuration to match the algorithm requirements at a point in time The book opens with an introductory chapter by Stephen Blust, Chair of the ITU-R WP8F Committee and Chair of the SDR Forum presenting a framework for SDR, in terms of definitions, evolutionary perspectives, introductory timescales and regulation. Suitable for today's engineers, technical staff and researchers within the wireless industry, the book will also appeal to marketing and commercial managers who need to understand the basics and potential of the technology for future product development. Its balance of industrial and academic contributors also makes it suitable as a text for graduate and post-graduate courses aiming to prepare the next generation of wireless engineers.

Download or read book That s the Way It Is written by Charles L. Ponce de Leon and published by University of Chicago Press. This book was released on 2016-09-09 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever since Newton Minow taught us sophisticates to bemoan the descent of television into a vast wasteland, the dyspeptic chorus of jeremiahs who insist that television news in particular has gone from gold to dross gets noisier and noisier. Charles Ponce de Leon says here, in effect, that this is misleading, if not simply fatuous. He argues in this well-paced, lively, readable book that TV news has changed in response to broader changes in the TV industry and American culture. It is pointless to bewail its decline. "That s the Way It Is "gives us the very first history of American television news, spanning more than six decades, from Camel News Caravan to Countdown with Keith Oberman and The Daily Show. Starting in the latter 1940s, television news featured a succession of broadcasters who became household names, even presences: Eric Sevareid, Walter Cronkite, David Brinkley, Peter Jennings, Brian Williams, Katie Couric, and, with cable expansion, people like Glenn Beck, Jon Stewart, and Bill O Reilly. But behind the scenes, the parallel story is just as interesting, involving executives, producers, and journalists who were responsible for the field s most important innovations. Included with mainstream network news programs is an engaging treatment of news magazines like "60 Minutes" and "20/20, " as well as morning news shows like "Today" and "Good Morning America." Ponce de Leon gives ample attention to the establishment of cable networks (CNN, and the later competitors, Fox News and MSNBC), mixing in colorful anecdotes about the likes of Roger Ailes and Roone Arledge. Frothy features and other kinds of entertainment have been part and parcel of TV news from the start; viewer preferences have always played a role in the evolution of programming, although the disintegration of a national culture since the 1970s means that most of us no longer follow the news as a civic obligation. Throughout, Ponce de Leon places his history in a broader cultural context, emphasizing tensions between the public service mission of TV news and the quest for profitability and broad appeal."
