Describe the process of data transmission with radio waves, microwaves, and infrared in wireless communication technology.

Question

Accepted Answer

In wireless communication, information is sent through signals that travel in the form of waves. Radio waves travel through the air and are used for Wi-Fi, mobile networks, and radio broadcasting - they can carry data over both short and long distances depending on frequency and power. Microwaves are higher-frequency waves used for satellite communication and long-distance point-to-point links, generally requiring a clear line of sight. Infrared signals use light waves just below visible light, work only over very short distances, are usually blocked by walls or obstacles, and are commonly used for remote controls and some short-range device communication.
