Wireless gear touches our lives in surprising ways. It’s not just computers and phones these days there’s wireless in everything from TVs and audio systems to planes, trains, and automobiles. To help you wrap your mind around the expanse of wireless, we take the time in this Part to lay out a vision of the wireless world. We talk
about where you find wireless and what flavor of wireless you can expect to find in each device and place. Then we spend some time looking at the nitty-gritty details about the standards and certifications — explaining key concepts like 802.11 and Wi-Fi — so that you’ll understand
exactly which pieces of wireless gear work together, and which don’t. We also review the pieces and parts that make up a wireless network. If you’ve already got a wireless network in place, you can skim through this quickly it’s always there for you to refer back to if you want. Finally, we review the equipment and services you need to connect your wireless networks to the Internet. Don’t underesti-mate the importance of this step — the value of your net-works increases exponentially as they are connected to other networks.
