Telecommunication involves the transmission of information over long distances using various types of waves. The waves commonly used for telecommunication include:
-
Radio Waves: Radio waves are widely used for wireless communication. They have a long wavelength and can travel long distances without significant loss of signal strength. They are used for broadcasting radio and television signals, as well as for mobile communication networks like 2G, 3G, 4G, and 5G.
-
Microwaves: Microwaves have a shorter wavelength than radio waves and are commonly used for point-to-point communication. They are used for satellite communication, microwave links for telephone networks, and wireless local area networks (WLANs) like Wi-Fi.
-
Infrared Waves: Infrared waves have a shorter wavelength than microwaves and are used for short-range wireless communication. They are used for applications like remote controls, infrared data transmission, and some wireless networking technologies.
-
Light Waves: Light waves, specifically in the form of optical fibers, are extensively used in long-distance communication systems. Fiber optic cables transmit data using pulses of light, offering high-speed and high-capacity transmission for applications such as internet connectivity, telephone networks, and cable television.
It’s worth noting that different forms of telecommunication may utilize different combinations of these waves, depending on the specific application and requirements.
