How Do Cell Phones Work

A very basic look at how cell phones work.

This book explains sounds waves, radio waves, and other key science ideas behind the technology of cell phones. The title discusses the parts of a cell phone as well as the path a call travels, and the social significance and future of cell phones.

Your fifth grader probably uses a cellphone most of the time. But does he/she know how it works? This picture book is an informative read that boosts your child’s technological advantage. It’s recommended that your child harvest as much knowledge about the world as possible. Go ahead and grab a copy of this picture book today.

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.

Most people carry a cell phone everywhere they go! But how do these everyday items work? This fact-filled title uses leveled text and bright photos to introduce the uses of cell phones, explore how they work, and consider what they might be like in the future. Diagrams help identify parts and explain how the phones work, while a question asks readers to think more deeply about the subject.

Here are some of the inventions that have made life easier. This book discusses information on cell phones, movies, computers and robots. How did these technological advancements begin and how did they evolve? Who invented them and how do they help improve daily living? You’ll know the answers to these questions once you start reading!

Comprehensive introduction to cell phone culture and theory.

Just as the automobile radically changed people's lives at the beginning of the 20th century, so too has the revolution in online services (including blogging, podcasting, videogaming, shopping, and social networking) and cell-phone use changed our lives at the turn of the 21st century. In addition, many other services, activities, and devices—including the Palm Pilot, the BlackBerry, the iPod, digital cameras, and cell cameras—have been made possible by the combination of these two technologies. Whereas the automobile allowed people for the first time to work in cities and live comfortably in the suburbs, extending the long commute beyond the limits previously circumscribed by public transportation, the Internet and cell phone allow us to interact with others from around the world—or a few hundred miles—from where we work or live, giving rise to the telecommuting phenomenon and allowing us to stay in touch with friends and families in the new virtual environment. As Hanson demonstrates in her new book, these technologies enable us to work and play 24/7, anytime, anywhere. What does this mean for us as individuals and for society as a whole? What are the social implications of this technological revolution that we have witnessed in the short span of about 20 years? Do people of different generations use these technologies in the same ways, or do they adopt them to support their communication habits formed at different times of their lives? How does the illusion of control provided by these technologies affect the way we think about what is meaningful in our lives? Hanson examines the wide-ranging impact of this change. How do individuals posting their viewpoints on the Internet affect democracy? Is it possible to ever completely prevent identity theft over the Internet? How permanent is information stored on the Internet or on a hard drive? Do cell phones change the way people think about privacy or the way they communicate with others? Does email? Do videogames teach new social principles? Do cell phones and the Internet change traditional communication behaviors and attitudes? Hanson discusses these crucial issues and explores to what extent individuals do have control, and she assesses how social and governmental services are responding to (or running from) the problems posed by these new technologies.
