Definition of Wireless Internetby Emilio Corsetti
In its simplest form, a wireless Internet connection allows access to the Internet over airwaves. A user with wireless Internet needs no hard-wired connection. The advantages are many: several computers can share a single Internet connection;users can access the Internet from any point within range of the signal; in some cases entire neighborhoods access the Internet via wireless, greatly reducing infrastructure costs.
In most home environments, wireless Internet access requires that at least one computer act as a hub. This computer will be directly connected to the Internet through cable, DSL or similar service. For a computer to serve as an Internet hub, that computer must also be connected to a wireless router.
A wireless router broadcasts the Internet connection and controls and sequences the sending and receiving of data packets.
In public locations such as airport terminals or coffee shops, laptop users with wireless connections can connect to the Internet via a hot spot. A hot spot is basically the access point from where the wireless signal is broadcast.
The fastest connections right now are 802.11a and 802.11g, which provides connections with a maximum speed of 54mbps.
The term Wi-Fi is often used interchangeably with wireless Internet.
