Wireless Internet
A wireless network may be a telecommunication network or a computer network that use radio waves for communication instead of physical layers. You can say this internet by satellites or companies own boosters. Firstly the experiment of wireless network was done in university of Hawaii in 1971. This wireless network was names ALOHA net. Later in 1982 AMPS (advance mobile phone services) system was adopt in America as a standard. After that many other countries develop their cellular network, some countries follow the USA standard while some design their own network. Today’s GSM is widely used cellular network for communication. Verizon wireless is also an example of a large local area network in US

Types Of Wireless Network
Wireless network is used in many different forms. The first one is wireless LAN (local area network). Before wireless technology the LAN was configured with cables. Now the most of the LAN’s are designed keeping in mind the wireless network. To establish a wireless network, wireless network card is attached with the system. In wireless LAN radio waves are used instead of wires to transmit data and information.

GSM (global system for mobiles) is a second type of wireless network. This wireless system is categorized in three ways, switching system, base station system and support system. The mobile phones firstly connected with the base system, base system transfer this connection to support and operation system, and after this the mobile is connected with the switching system. This is mostly adopted mobile wireless system and almost all the mobile system providers used this technique. Prepaid wireless connection is mostly used in the mobiles, where you have to prepay for which you are going to used. Cingular wireless is its largest example in US.

While in computer system, the Wi-Fi system is used for wireless communication. Through Wi-Fi you can connect to the internet and other systems. The Wi-Fi system broadcast the radio waves, which can only be catch by a Wi-Fi receiver. This kind of connection is satellite internet connections. Many wireless internet providers offer many packages; select which one is suitable to you.

Another mostly used type of wireless network is fixed wireless data, in these two or more buildings are connected to shared or extend the network with out any wire. Wireless routers are also available for this purpose.
