Wireless Networking

One great way to work “unplugged” is to maintain your network or Internet connection with wireless networking. Radio-based networking technology has advanced rapidly in recent years, and it’s being deployed in schools, universities, corporations and, oddly enough, coffee houses. Whether you’re at a client’s desk or in an overstuffed chair sipping a cafe latte, as long as you’re within hundred feet or so of a network access point, you’re online.

For a portable computer, what you’ll need is a PC-card based radio transmitter/receiver. Windows XP has built-in support for the 802.11 security and signaling protocol used in Wireless networking. The protocol ensures that the data rate is adjusted up and down as the quality of the radio signal reception varies.
