Chapter 3. How Wireless Works > Wireless Fidelity

Wireless Fidelity

When it comes to wireless networking standards, there's only one standard you're likely to run across (or to want to use in most cases): IEEE 802.11b, known more familiarly by a trademarked name, Wi-Fi. Wi-Fi is short for “wireless fidelity” and, as of the end of 2002, encompasses both 802.11b and another, faster standard called 802.11a. Macintosh users have long known 802.11b by Apple's name for the technology, AirPort.

802.11b has become the dominant wireless networking technology because in the space of a few years, tens of millions of 802.11b cards and access points have been sold, and thousands of articles have been written about it. We don't try to pick winners or losers, but we do know that 802.11b is the only wireless standard that's in wide use, is easy to set up, and has no spectrum or metering costs (unlike cell service or a few high-end business forms of wireless networking).
