Wi-Fi refers to the current industry standard for wireless LANs (Local Area Networks), which provide users high-speed mobile Internet access without the inconvenience of cords and cables. Wi-Fi is based on the 802.11b platform, developed and supported by the Institute of Electrical and Electronics Engineers (IEEE).
Wi-Fi networks consist of access points that generate transmissions of a specific radio frequency designated for such use. The signals can be picked up by laptop computers and other mobile devices (through either built-in or added-on network components). As a result, users gain Internet connectivity at up to 50 times faster than with a standard dial-up modem. Major computer manufacturers now offer notebook computers with built-in Wi-Fi capability, and any standard notebook computer can be made Wi-Fi-enabled by simply plugging in an appropriate Wi-Fi network card (PCMCIA card).
Wi-Fi connects you to the Internet without the restriction of wires, cables or fixed connections. Wi-Fi gives you freedom to change locations — and to have full access to your files, office and network connections wherever you are. No other networking technology used to set up a small home or SOHO network provides the convenience or mobility of a Wi-Fi network. That's because other methods, including standard wired Ethernet networks and phone line and power line-based networks, all require a connection via wire or cable.
