Definition of Wireless Internet

by 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.

Hot spots

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.
