Wi-Fi is “short for wireless fidelity and is meant to be used generically when referring of any type of 802.11 network, whether 802.11b, 802.11a, dual-band, etc. The term is promulgated by the Wi-Fi Alliance.” Wi-Fi networks consist of transmitting specific radio waves to wirelessly connect computers to each other, to the Internet, or to wired networks. “The signals can be picked up by specially enabled notebook computers (through either built-in or added-on network components). Computer manufacturers offer notebook computers with built-in

A Wi-Fi hotspot is created by installing an access point to an internet connection. The access point transmits a wireless signal over a short distance — typically covering around 300 feet. Most access points have an integrated Ethernet controller to connect to an existing wired-Ethernet network. When a Wi-Fi -enabled device, such as a Pocket PC, encounters a hotspot, the device can then connect to that network wirelessly. Most hotspots are located in places that are readily accessible to the public, like airports, coffee shops, hotels, book stores and campus environments. While some hotspots are free, the most robust public Wi-Fi networks are provided by private internet service providers (ISPs) that charge a fee for users to connect to the internet.

A Wi-Fi network can connect computer’s together to share such hardware and software resources as printers and the Internet. That means everyone patched can share stored files, photos, and documents and print them out on a single printer attached to one desktop computer—all without unsightly cables. In a home or home office, using Wi-Fi equipment, your wireless network gives you the ability to share a single high-speed broadband cable or DSL connection. A Wi-Fi network can easily be expanded to ten users or more. Wi-Fi networks
