The Cellphone
Presenting the history of the cellular phone from its beginnings in the 1940s to the present, this book explains the fundamental concepts involved in wireless communication along with the ramifications of cellular technology on the economy, U.S. and international law, human health, and society. The first two chapters deal with bandwidth and radio. Subsequent chapters look at precursors to the contemporary cellphone, including the surprisingly popular car phone of the 1970s, the analog cellphones of the 1980s and early 1990s, and the basic digital phones which preceded the feature-laden, multipurpose devices of today.

Cell Phone Science
Their buzzes, beeps, bells, and tunes have disrupted countless classes, movies, and meals; public auditoriums now have signs posted prominently asking people to turn their cell phones off; cities such as Santa Fe have banned their use in automobiles. But these little connection gadgets have become ubiquitous because they are so useful-many would blanch at the thought of losing their cell phone. Cell phones are useful because of the science, technology, and design that are blended to make them function. In this work, authors Michele Sequeira and Michael Westphal help young people explore this now-commonplace, socially important gadget that connects today's youth with their friends. The underlying science and technologies, and some of the history that has influenced the development of cell phones, are discussed. Emphasis is given to building science and technology concepts through simple analogies with commonplace items and ideas.
