How Does Wireless Internet Work?

Wireless internet allows computers, mobile phones, PDAs etc. to send and receive data via the internet without the use of any physical connection between the device and the network.

The technology behind wireless internet is similar to mobile phones. Radio frequency signals exchange information between the device and the base station, or access point, which then relays the data via the wired infrastructure to and from the Internet.

If you are thinking about setting up a wireless internet connection at home you will need some kit to do this. You will also need a broadband connection to feed into this kit. Typical home setups usually use a wireless modem or wireless access point to generate the WIFI signal around the house. Computers in other rooms of the house also require wireless access hardware to pick up the signal generated by the access point / modem.

The working of a wireless internet is simple and all it requires is a net, a location and most of all your equipment. Let's see this working with the help of an example. XYZnet has its own antennas situated in a particular county, which is connected straight to the main line out to the internet. These antennas usually function on a 2.4 Ghz frequency, which in turn permits XYZnet to transmit an internet connection up to 10 miles from every antenna. Every customer in this locality must have an antenna, radio and a computer, so that they are able to receive/transmit back to XYZnet. This connection provides you with live 24 hours a day, 7 days a week and most of all the weather does not affect your connection in any way.
