Wireless

Wireless refers to the ability to transmit data usually through electromagnetic waves rather than through a wire connection. Wireless data can also be transmitted through infrared or laser technology for small distances. Devices such as radios, computers and mobile phones use such technology to communicate to other devices. When there is more than one device connected wirelessly, it is called a wireless network. Today’s technology is making wireless communication more frequently available. The interaction between devices and between a user and the devices is designed to be a seamless activity, so that when one connects to the web on a mobile phone wirelessly, it becomes as easy as turning on a radio by just pressing a button. Fixed wireless is found in fixed locations such as at home or in the office. Fixed wireless is only available to those within the boundaries of the wireless system. Wireless LAN (Local Area Network) uses electromagnetic waves between computers in the same network. Wireless MAN connects wireless LANs together and Wi-Fi connects the Internet to other machines.
