In this fascinating history of the portable radio, Michael Schiffer shows how this invention is as American as apple pie. Along the way, he tells how technology has responded to consumer preference, how corporate "cryptohistory" has made us believe the Japanese invented the radio, and how the spread of the portable radio mirrors that of other technologies. More than 400 photographs make this book both a definitive resource and a delightful browse.

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 chang...

Did you know . . . that portable radios were first envisioned in 1890 science fiction?; that the first 3boom boxes2 were made in the 1920s?; that personal portables first appeared in the 1940s?; that the first transistor radio was manufactured in Indianapolis, not Tokyo? In this fascinating history of the portable radio, Michael Schiffer shows how this invention is as American as apple pie. Along the way, he tells how technology has responded to consumer preference, how corporate 3cryptohistory2 has made us believe the Japanese invented the radio, and how the spread of the portable radio mirrors that of other technologies.

This book covers the fundamental principles behind the design of ultra-low power radios and how they can form networks to facilitate a variety of applications within healthcare and environmental monitoring, since they may operate for years off a small battery or even harvest energy from the environment. These radios are distinct from conventional radios in that they must operate with very constrained resources and low overhead. This book provides a thorough discussion of the challenges associated with designing radios with such constrained resources, as well as fundamental design concepts and practical approaches to implementing working designs. Coverage includes integrated circuit design, timing and control considerations, fundamental theory behind low power and time domain operation, and network/communication protocol considerations.
A timely overview of a complete spectrum of technologies specifically designed for public safety communications as well as their deployment as management In our increasingly disaster-prone world, the need to upgrade and better coordinate our public safety networks combined with successful communications is more critical than ever. Fundamentals of Public Safety Networks and Critical Communications Systems fills a gap in the literature by providing a book that reviews a comprehensive set of technologies, from most popular to the most advanced communications technologies that can be applied to public safety networks and mission-critical communications systems. The book explores the technical an...
