Wireless communication

 

Wireless communication, or sometimes simple wireless transmission, transfers information or energy between two or more points, and these points are not connected by a conductor. Common wireless technologies use radio waves. With radio waves, the distance can be very short. For example, the distance of Bluetooth is only a few meters, and the distance of deep-space radio communication can reach millions of kilometers. It includes various types of fixed, mobile and portable applications, including two-way radios, mobile phones, personal digital assistants (PDAs) and wireless networks. Other examples of radio wireless technology applications include global positioning system units, garage door openers, wireless computer mice, keyboards and earphones, earphones, radio receivers, satellite TV, broadcast TV, and cordless phones. Some of the less common ways to achieve wireless communication include the use of other electromagnetic wireless technologies, such as the use of light, magnetic or electric fields, or sound.

In the history of communication, the word wireless has been used twice, with slightly different meanings. It was originally used in a radio transmission and reception technology around 1890, such as wireless telegraphy, until the new word radio replaced it around 1920. This term reappeared in the 1980s and 1990s, mainly to distinguish digital devices that do not have wires for communication, such as the examples listed in the previous paragraph and digital devices that require wires or cables. In the 2000s, this became its main application due to the advent of technologies such as mobile broadband, Wi-Fi, and Bluetooth.

Wireless operation allows services such as remote communication, which are impossible or impractical to use wires. This term is commonly used in the telecommunications industry to refer to telecommunications systems (such as radio transmitters and receivers, remote controls, etc.). It uses some form of energy (such as radio waves, sound energy) to transmit information without using wires. In this way, information is transmitted over short and long distances.
