What does Wireless Technology mean?
Wireless technology refers to technology that allows us to communicate without using cables or wires. Wireless technology includes RF and IR waves. RF and IR stand for radio frequency and infrared respectively. Wireless communication (or just wireless, when the context allows) is the electromagnetic transfer of information between two or more points that do not use an electrical conductor as a medium by which to perform the transfer. The most common wireless technologies use radio waves.
Wireless technology today
Local Wi-Fi networks
Wi-fi is a technology that allows tablets, video game consoles, printers, and smartphones to communicate with the Internet. Medical devices, laptops, and digital audio players also use Wi-Fi. The term ‘Wi-Fi’ emerged in the 1990s from the words ‘Wireless’ plus ‘Fi,’ which was an arbitrary second element, after ‘Hi-Fi.’ People often mistakenly interpret the term as a short form of ‘Wireless Fidelity.’
Cellular networks (mobile phone networks)
This technology allows electronic devices to communicate over long distances.“Wireless’ is a broad term that encompasses all sorts of technologies and devices that transmit data over the air rather than over wires, including cellular communications, networking between computers with wireless adapters and wireless computer accessories.”
