Wi-Fi refers to the current industry standard for wireless LANs (Local Area Networks), which provide users high-speed mobile Internet access without plugging in with cords or 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 specially enabled notebook computers (through either built-in or added-on network components), enabling users to enjoy Internet connectivity at about 200 times faster than a dial-up modem. Major computer manufacturers, including Dell, IBM and Compaq, offer notebook computers with built-in Wi-Fi capability, and any standard notebook computer can easily become Wi-Fi-enabled by simply plugging in an appropriate Wi-Fi network card (also known as a PCMCIA card).
