Wi-Fi and the Bad Boys of Radio

Book Description
At 36,000 feet, Wi-Fi converts our airline seats to remote offices. It lets us read email in airports, watch video in coffee shops, and listen to music at home. Wi-Fi is everywhere. But where did it come from? Wi-Fi and the Bad Boys of Radio takes us back to when the Internet was first gaining popularity, email took ten minutes to load up, and cell phones were big and unwieldy. But Alex Hills had a vision: people carrying small handheld devices that were always connected. His unwavering purpose was to change the way we use the Internet. After being a teenage "ham operator" and bringing radio, TV and telephone service to the Eskimos of northern Alaska, Dr. Hills led a small band of innovators to overcome "the bad boys of radio" - the devilishly unpredictable behavior of radio waves - and build the network that would become the forerunner to today's Wi-Fi. "I know of no one so capable of telling the Wi-Fi story and explaining so clearly how the technology works. Alex Hills is certain to capture the public imagination with this new book." Jim Geier, Principal Consultant, Wireless-Nets, Ltd. and Wi-Fi author "Alex Hills has contributed to the developing world and to developing advanced wireless technology at one of the world's most tech-savvy universities. Working on both frontiers, Dr. Hills pioneered wireless Internet and launched a revolution in the way the world communicates. His story of how we "cut the cord" begins in a place where there were no cords to begin with -- remote Alaska." Mead Treadwell, Lieutenant Governor of Alaska and former Chair, United States Arctic Research Commission Alex Hills is Distinguished Service Professor of Engineering & Public Policy and Electrical & Computer Engineering at Carnegie Mellon University. Dr. Hills is frequently invited to speak at conventions, conferences, university seminars, corporate training sessions, and community events. His talks, with their vivid stories and clear explanations of technology, have been well-received by audiences throughout the United States and in more than twenty foreign countries. An inventor with eleven patents, Dr. Hills can write and speak in technical jargon. But in his writing, as in his talks, he speaks to everyone -- technical specialists and the public alike. People of all backgrounds have been fascinated by his contributions to Scientific American and IEEE Spectrum magazines -- articles that explain technology in a style that is clear to any reader.

Book Description
An accessible, comic book-like, illustrated introduction to how the internet works under the hood, designed to give people a basic understanding of the technical aspects of the Internet that they need in order to advocate for digital rights. The internet has profoundly changed interpersonal communication, but most of us don't really understand how it works. What enables information to travel across the internet? Can we really be anonymous and private online? Who controls the internet, and why is that important? And... what's with all the cats? How the Internet Really Works answers these questions and more. Using clear language and whimsical illustrations, the authors translate highly technical topics into accessible, engaging prose that demystifies the world's most intricately linked computer network. Alongside a feline guide named Catnip, you'll learn about: • The "How-What-Why" of nodes, packets, and internet protocols • Cryptographic techniques to ensure the secrecy and integrity of your data • Censorship, ways to monitor it, and means for circumventing it • Cybernetics, algorithms, and how computers make decisions • Centralization of internet power, its impact on democracy, and how it hurts human rights • Internet governance, and ways to get involved This book is also a call to action, laying out a roadmap for using your newfound knowledge to influence the evolution of digitally inclusive, rights-respecting internet laws and policies. Whether you're a citizen concerned about staying safe online, a civil servant seeking to address censorship, an advocate addressing worldwide freedom of expression issues, or simply someone with a cat-like curiosity about network infrastructure, you will be delighted -- and enlightened -- by Catnip's felicitously fun guide to understanding how the internet really works!

Book Description
As we all know by now, wireless networks offer many advantages over fixed (or wired) networks. Foremost on that list is mobility, since going wireless frees you from the tether of an Ethernet cable at a desk. But that's just the tip of the cable-free iceberg. Wireless networks are also more flexible, faster and easier for you to use, and more affordable to deploy and maintain.The de facto standard for wireless networking is the 802.11 protocol, which includes Wi-Fi (the wireless standard known as 802.11b) and its faster cousin, 802.11g. With easy-to-install 802.11 network hardware available everywhere you turn, the choice seems simple, and many people dive into wireless computing with less thought and planning than they'd give to a wired network. But it's wise to be familiar with both the capabilities and risks associated with the 802.11 protocols. And 802.11 Wireless Networks: The Definitive Guide, 2nd Edition is the perfect place to start.This updated edition covers everything you'll ever need to know about wireless technology. Designed with the system administrator or serious home user in mind, it's a no-nonsense guide for setting up 802.11 on Windows and Linux. Among the wide range of topics covered are discussions on: deployment considerations network monitoring and performance tuning wireless security issues how to use and select access points network monitoring essentials wireless card configuration security issues unique to wireless networks With wireless technology, the advantages to its users are indeed plentiful. Companies no longer have to deal with the hassle and expense of wiring buildings, and households with several computers can avoid fights over who's online. And now, with 802.11 Wireless Networks: The Definitive Guide, 2nd Edition, you can integrate wireless technology into your current infrastructure with the utmost confidence.
