Signal Traffic
The contributors to Signal Traffic investigate how the material artifacts of media infrastructure--transoceanic cables, mobile telephone towers, Internet data centers, and the like--intersect with everyday life. Essayists confront the multiple and hybrid forms networks take, the different ways networks are imagined and engaged with by publics around the world, their local effects, and what human beings experience when a network fails. Some contributors explore the physical objects and industrial relations that make up an infrastructure. Others venture into the marginalized communities orphaned from the knowledge economies, technological literacies, and epistemological questions linked to infrastructural formation and use. The wide-ranging insights delineate the oft-ignored contrasts between industrialized and developing regions, rich and poor areas, and urban and rural settings, bringing technological differences into focus. Contributors include Charles R. Acland, Paul Dourish, Sarah Harris, Jennifer Holt and Patrick Vonderau, Shannon Mattern, Toby Miller, Lisa Parks, Christian Sandvig, Nicole Starosielski, Jonathan Sterne, and Helga Tawil-Souri.

Empires of Entertainment
Empires of Entertainmentintegrates legal, regulatory, industrial, and political histories to chronicle the dramatic transformation within the media between 1980 and 1996. As film, broadcast, and cable grew from fundamentally separate industries to interconnected, synergistic components of global media conglomerates, the concepts of vertical and horizontal integration were redesigned. The parameters and boundaries of market concentration, consolidation, and government scrutiny began to shift as America's politics changed under the Reagan administration. Through the use of case studies that highlight key moments in this transformation, Jennifer Holt explores the politics of deregulation, the reinterpretation of antitrust law, and lasting modifications in the media landscape.
Holt skillfully expands the conventional models and boundaries of media history. A fundamental part of her argument is that these media industries have been intertwined for decades and, as such, cannot be considered separately. Instead, film, cable and broadcast must be understood in relation to one another, as critical components of a common history.Empires of Entertainmentis a unique account of deregulation and its impact on political economy, industrial strategies, and media culture at the end of the twentieth century.

Broadband communications via high-altitude platforms
In this book, the authors provide a thorough overview of the state of the art in high-altitude platform (HAP) enabling technologies, addressing recent research activities and results. In addition, the book explores the enabling technologies and economics of HAP-based communication systems, including issues related to aeronautics, applications and business modelling, as well as future trends. Furthermore, the authors discuss broadband wireless communications from HAPs, the operating environment, and advanced communication techniques for efficient radio link resource management. Similarly, the authors complement radio frequency (RF) dominated issues with free space optical communications in the HAP operating environment, focusing on physical and networking layers. Finally, the book addresses the multiple HAP constellations planning procedure and discusses the networking implications of using multiple HAPs. Key Features: Focuses on placing HAPs in the perspective of current and future broadband wireless communication systems Offers an overview of the constraints affecting HAP-based broadband communications Provides a thorough overview and state of the art of the HAP enabling technologies, including recent research activities and future directions Examines the operating environment, advanced communication techniques for efficient radio link resource management, and suitable antennas Addresses multiplatform constellations, presenting the multiple HAP constellation planning procedure and discussing the networking implications of using multiple HAPs This book will be of valuable interest to researchers and practitioners in the areas of wireless communications, satellite communications and high-altitude platforms, and development engineers involved in the design and development of HAP systems.

Behavioral Modeling and Predistortion of Wideband Wireless Transmitters
Covers theoretical and practical aspects related to the behavioral modelling and predistortion of wireless transmitters and power amplifiers. It includes simulation software that enables the users to apply the theory presented in the book. In the first section, the reader is given the general background of nonlinear dynamic systems along with their behavioral modelling from all its aspects. In the second part, a comprehensive compilation of behavioral models formulations and structures is provided including memory polynomial based models, box oriented models such as Hammerstein-based and Wiener-based models, and neural networks-based models. The book will be a valuable resource for design engineers, industrial engineers, applications engineers, postgraduate students, and researchers working on power amplifiers modelling, linearization, and design.

Future Telco : successful positioning of network operators in the digital age
\"This book examines the extensive changes in markets, technologies and value chains that telecommunication companies are currently confronted with. It analyzes the crossroads they have reached and the choices that now need to be made - to be a bit pipe or a trendsetter of digitalization. Based on an analysis of the key challenges for telcos, the book derives future market scenarios and puts forward recommendations for how they can successfully position themselves. It proposes a framework based on seven \"levers,\" which addresses concrete measures in each step of the value chain, ranging from technology, IT and processes, to innovation, marketing and sales issues. The book discusses the current challenges and provides both general recommendations and concrete solutions. Respected experts illustrate innovative strategic and technical trends and provide insights gained in real-life transformation projects. Recent developments in the areas of regulation, product development, competition between over-the-top (OTT) providers and telcos, as well as technical innovations like 5G, SDN/NFV, LEO satellites and MEC are discussed. Accordingly, practitioners, managers and researchers alike will benefit from the book's wealth of examples and up-to-date insights\"--Publisher's website.

Financing information and communication infrastructure needs in the developing world : public and private roles
Over the past ten years, private-sector-led growth has revolutionized access to telecommunications. Every region of the developing world benefitted in terms of investment and rollout. This revolution would have been impossible without government reform and oversight. Advanced information and communication infrastructure (ICI) are increasingly important to doing business in a globalizing world. Governments, enterprises, civil society, workers, and poor populations in the developing countries need more affordable access. This report proposes strategies that governments can carry out to attract private investment and ensure the continued evolution and spread of information and communication infrastructure. These strategies encompass more than sector policy alone, for investment decisions are based on a wide range of factors including, for example, the roles played by financial sector development and the broader investment environment. The strategies also include potential public sector investments that can catalyze ICI rollout in subsectors where the private sector is not prepared to intervene on its own.
