Wireless communication is the transmission of the information signals without any physical connection, via technologies such as cordless telephones, cellular telephones or microwaves. ‘Wireless’ means any type of electrical or electronic operation that is accomplished without the use of any hard wired connection. Many of these operations may also be accomplished with the use of wires if required, while others such as long range communications are impossible or impractical to implement with the use of wires.
According to estimate, approximately more than 62 million of the people use wireless devices to access the Internet by 2003. Mobile communication has become significantly vital at a fast growing speed. Mobile phones or the notebook, PDAs, home theatre system, car or lorry, including all mobile devices have built-in technologies for the wireless communication. GSM, UMTS, Wireless LAN and GPS are only the most common services representing the complexities of the newly developed technologies.
‘Wireless’ is the most common term that is used in the industry of telecommunications refer to the telecommunications systems, for example radio transmitters and receivers, remote controls, computer networks, network terminals, and so on, using a form of energy – radio frequency, infrared light, visible light, acoustic energy for transferring the information without the use of wires, in this way, information is transferred over both the short as well as long distances.
Do not be confused with the term ‘cordless’ that is used to refer to powered electrical or electronic devices that are able to operate from a portable power source without any cable or cord for limiting the mobility of the cordless device via a connection to the main power supply.
