Radio technology refers to the transmission and reception of electromagnetic waves to communicate information over distances. It operates by converting sound, data, or video into radio waves, which are then sent through the air. These waves can travel long distances and penetrate various obstacles, making radio a versatile medium for communication. The technology is widely used in various applications, including broadcasting, two-way radios, and cellular networks. Devices like radios and smartphones utilize radio technology to connect users, allowing for voice calls, music streaming, and data transfer. This technology has significantly impacted how people communicate and access information globally.
