History Of Wireless

Important new insights into how various components and systems evolved Premised on the idea that one cannot know a science without knowing its history, History of Wireless offers a lively new treatment that introduces previously unacknowledged pioneers and developments, setting a new standard for understanding the evolution of this important technology. Starting with the background-magnetism, electricity, light, and Maxwell's Electromagnetic Theory-this book offers new insights into the initial theory and experimental exploration of wireless. In addition to the well-known contributions of Maxwell, Hertz, and Marconi, it examines work done by Heaviside, Tesla, and passionate amateurs such as the Kentucky melon farmer Nathan Stubblefield and the unsung hero Antonio Meucci. Looking at the story from mathematical, physics, technical, and other perspectives, the clearly written text describes the development of wireless within a vivid scientific milieu. History of Wireless also goes into other key areas, including: The work of J. C. Bose and J. A. Fleming German, Japanese, and Soviet contributions to physics and applications of electromagnetic oscillations and waves Wireless telegraphic and telephonic development and attempts to achieve transatlantic wireless communications Wireless telegraphy in South Africa in the early twentieth century Antenna development in Japan: past and present Soviet quasi-optics at near-mm and sub-mm wavelengths The evolution of electromagnetic waveguides The history of phased array antennas Augmenting the typical, Marconi-centered approach, History of Wireless fills in the conventionally accepted story with attention to more specific, less-known discoveries and individuals, and challenges traditional assumptions about the origins and growth of wireless. This allows for a more comprehensive understanding of how various components and systems evolved. Written in a clear tone with a broad scientific audience in mind, this exciting and thorough treatment is sure to become a classic in the field.

Since the discovery of electromagnetic waves less than 150 years ago, the application of wireless communications technology has not only revolutionized our daily lives, but also fundamentally changed the course of world history. A Brief History of Everything Wireless charts the fascinating story of wireless communications. The book leads the reader on an intriguing journey of personal triumphs and stinging defeats, relating the prominent events, individuals and companies involved in each progressive leap in technology, with a particular focus on the phenomenal impact of each new invention on society. Beginning at the early days of spark-gap transmitters, this tale touches on the emergence of radio and television broadcasting, as well as radio navigation and radar, before moving on to the rise of satellite, near-field and light-based communications. Finally, the development of wireless home networks and the explosive growth of modern cellular technologies are revealed, complete with a captivating account of their corresponding company histories and behind-the-scenes battles over standards. For those wishing to peek behind the magic curtain of friendly user interfaces and clever engineering, and delve further into various processes underlying the ubiquitous technology we depend upon yet take for granted, the book also contains special “TechTalk” chapters that explain the theoretical basics in an intuitive way.

In 1873 Scottish physicist James Clerk Maxwell first advanced the idea that there might be electromagnetic waves that were similar to light waves, a startling concept to the scientists of his day. About 13 years later, German physicist Heinrich Hertz demonstrated in his laboratory that electromagnetic radiation did indeed exist. But it was not until after Hertz's death that a young Italian named Guglielmo Marconi got the idea for a practical communications system based on Hertz's work. Marconi was surprised and disappointed that the Italian government was not interested in his newly discovered wireless communications system, and thus he took his equipment to England. From that point on, the wireless became identified with Britain. From these beginnings, wireless radio became the basis of a revolution that has resulted in the satellite communications of today. This history first looks at Marconi's invention and then explores its many applications, including marine radio, cellular telephones, police and military uses, television and radar. Radio collecting is also discussed, and brief biographies are provided for the major figures in the development and use of the wireless.

A new look at the early history of wireless communication. By 1897 Guglielmo Marconi had transformed James Clerk Maxwell's theory of electromagnetic waves into a workable wireless telegraphy system, and by 1907 Lee de Forest had invented the Audion, a feedback amplifier and oscillator that opened the way to practical radio transmission. Fifteen years after Marconi's invention, wireless had become an essential means of communication, as well as a hobby for many. This book offers a new perspective on the early days of wireless communication. Drawing on previously untapped archival evidence and recent work in the history and sociology of science and technology, it examines the substance and context of both experimental and theoretical aspects of engineering and scientific practices in the first years of this technology. It offers new insights into the relationship between Marconi and his scientific advisor, the physicist John Ambrose Fleming (inventor of the vacuum tube). It includes the full story of the infamous 1903 incident in which Marconi's opponent Nevil Maskelyne interfered with Fleming's public demonstration of Marconi's syntonic (tuning) system at the Royal Institution by sending derogatory messages from his own transmitter. The analysis of the Maskelyne affair highlights the struggle between Marconi and his opponents, the efficacy of early syntonic devices, Fleming's role as a public witness to Marconi's private experiments, and the nature of Marconi's "shows." It also provides a rare case study of how the credibility of an engineer can be created, consumed, and suddenly destroyed. The book concludes with a discussion of de Forest's Audion and the shift from wireless telegraphy to radio.

Behind the Wireless tells the story of women at the BBC in the 1920s and 30s. Broadcasting was brand new in Britain and the BBC developed without many of the overt discriminatory practices commonplace at the time. Women were employed at all levels, except the very top, for instance as secretaries, documentary makers, advertising representatives, and librarians. Three women held Director level posts, Hilda Matheson (Director of Talks), Mary Somerville (Director of School Broadcasting), and Isa Benzie (Foreign Director). Women also produced the programmes aimed at female listeners and brought women broadcasters to the microphone. There was an ethos of equality and the chance to rise through the ranks from accounts clerk to accompanist. But lurking behind the façade of modernity were hidden inequalities in recruitment, pay, and promotion and in 1932 a marriage bar was introduced. Kate Murphy examines how and why the interwar BBC created new opportunities for women.

This textbook takes a unified view of the fundamentals of wireless communication and explains cutting-edge concepts in a simple and intuitive way. An abundant supply of exercises make it ideal for graduate courses in electrical and computer engineering and it will also be of great interest to practising engineers.

This mathematics based book has the purpose of explaining Faraday's lines of force in mathematical terms. One would need a good grasp Faraday's theories, basic physics, and mathematical algebra to fully comprehend the arguments put forth.

Wireless technology has become deeply embedded in everyday life, but its impact cannot be fully understood without probing the contributions of the Italian inventor Guglielmo Marconi (1874-1937), who ushered in the beginning of wireless communication. Marconi produced and detected sound waves over long distances, using the curvature of the earth for direction, and laid the foundations for what we know as radio—the original mobile, voice-activated, and electronic media community. Timothy C. Campbell demonstrates that Marconi’s invention of the wireless telegraph was not simply a technological act but also had an impact on poetry and aesthetics and linked the written word to the rise of mass politics. Reading influential works such as F. T. Marinetti’s futurist manifestos, Rudolf Arnheim’s 1936 study Radio, writings by Gabriele D’Annunzio, and Ezra Pound’s Cantos, Campbell reveals how the newness of wireless technology was inscribed in the ways modernist authors engaged with typographical experimentation, apocalyptic tones, and newly minted models for registering voices. Wireless Writing in the Age of Marconi presents an alternative history of modernism that listens as well as looks and bears in mind the altered media environment brought about by the emergence of the wireless. Timothy C. Campbell is associate professor of Italian at Cornell University.
