Odilile Ayodele: The Political Economy
of Mobile Telephony in South Africa

The Political Economy of Mobile Telephony in South Africa

Mtn, Vodacom and the State

"A wondrous story of scientific endeavor-probing the great ice sheets of AntarcticaFrom the moment explorers set foot on the ice of Antarctica in the early nineteenth century, they desired to learn what lay beneath. David Drewry provides an insider's account of the ambitious and often hazardous radar mapping expeditions that he and fellow glaciologists undertook during the height of the Cold War, when concerns about global climate change were first emerging and scientists were finally able to peer into the Antarctic ice and take its measure.In this panoramic book, Drewry charts the history and breakthrough science of Radio Echo Sounding, a revolutionary technique that has enabled researchers to measure the thickness and properties of ice continuously from the air-transforming our understanding of the world's great ice sheets. To those involved in this epic fieldwork, it was evident that our planet is rapidly changing, and its future depends on the stability and behavior of these colossal ice masses. Drewry describes how bad weather, downed aircraft, and human frailty disrupt the most meticulously laid plans, and how success, built on remarkable international cooperation, can spawn institutional rivalries.The Land Beneath the Ice captures the excitement and innovative spirit of a pioneering era in Antarctic geophysical exploration, recounting its perils and scientific challenges, and showing how its discoveries are helping us to tackle environmental challenges of global significance"--

Array Beamforming Enabled Wireless Communications

Routledge Library Editions: Broadcasting

Behind the Tube (1990) tells the story of the unseen foundation of modern radio, TV and cable - the technology that enables programming to reach an audience. It charts the evolution of this technology in all its facets - technical, personal, economic and social.

A History of Broadcasting Technology and Business

Behind the Tube

Broadcast Transmission Engineering Practice (1992) contains a wealth of technical knowledge and practical experience, as well as detailed guidance on how to initiate, supervise and bring transmission engineering projects to fruition.

Discover the exciting world of software-defined radio (SDR) through this hands-on, beginner-friendly introduction. Whether you’re a hobbyist interested in exploring the airwaves, a student learning about wireless communications, or an engineer looking to prototype RF designs, Practical SDR will help you master the fundamentals of software-defined radio. You’ll build virtual radio receivers on your computer, then extract audio from real AM and FM signals; learn how amplitude modulation works by building an AM radio; understand signal filtering by crafting clean FM reception; and grasp complex topics like IQ sampling. You’ll use the intuitive GNU Radio Companion interface to create working radio systems piece by piece, then move on to building functional AM and FM receivers, and even design your own radio transmitter. Along the way, you’ll learn how to: <ul><li>Manipulate radio frequencies from 1 MHz to 6 GHz</li><li>Use filters and gain control to extract clear signals from noise</li><li>Maximize your SDR’s performance by choosing the right antennas and RF hardware</li><li>Process complex, real-time IQ data to demodulate actual radio signals</li><li>Build a flexible, virtual radio testing environment on your computer</li></ul> This isn’t just another theory book. Practical SDR bridges the gap between basic tutorials and advanced applications, providing a solid foundation for diving into modern wireless systems like Wi-Fi, Bluetooth, and cellular communications. Some projects require SDR hardware, such as a HackRF One, and a compatible antenna.

"This book sets out to investigate the political, technological, and environmental dimensions of architecture at a moment when buildings began to interact with the emergent medium of radio. More especially it explores Cold War Berlin, through the Haus des Rundfunks, occupied by the Soviet forces on the Eastern side of the city"--

A historical and theoretical account of the city of Berlin from the intertwined perspectives of architecture, environmental, and media studies. In 1945, having occupied German territory, Soviet troops made two strategic moves: they dismantled the Deutschlandsender III radio transmission tower, the single tallest structure at the time in Europe, and they seized the Haus des Rundfunks in West Berlin, a monumental building designed by Hans Poelzig. These moves were crucial both symbolically and technically, as together they sparked what would become a veritable radio war between the Eastern and Western blocs during the Cold War. In Radio-Activities, Alfredo Thiermann Riesco investigates this spatial conflict as he interrogates the political, technological, and environmental dimensions of architecture at a time when buildings began to interact with the remote transmission of information. By its very nature, the medium of radio promised to evaporate the intrinsic material aspect of architecture; in fact, it did no such thing. By way of transscalar analyses, Thiermann Riesco pays particular attention to Berlin’s buildings, walls, transmission towers, factories, research institutions, and territorial organizations during the Cold War period, which enabled the production, reproduction, and transmission of sonic-based content across the divide of the Iron Curtain. In doing so he reveals underresearched continuities between politics, technology, media, and architecture, in the process reframing notions of national and transnational boundaries. A timely and fascinating study, Radio-Activities brilliantly interrogates the status and agency of buildings during a period—not unlike today’s—of increasingly hyperconnected, ubiquitous, and invisible modes of coexistence.

"With the exponential growth in indoor wireless communication, the necessity for novel technologies to manage the escalating data traffic becomes increasingly paramount. This chapter delves into the potential of hybrid systems as a viable solution to surmount the prevailing limitations in wireless communication. Initially, it provides a comprehensive overview of existing communication mediums, encompassing wireless communication RF communication, optical communication, and Visible Light Communication (VLC). Subsequently, the discussion pivots towards the intricacies and obstacles within VLC, exploring potential solutions to these challenges. Emphasizing the pivotal role of hybrid systems in optimizing indoor wireless communication networks, this chapter elucidates the constructive collaboration between various communication technologies to meet the evolving demands of modern communication infrastructures."--
