Radio transmission is the process of sending information through electromagnetic waves. These waves carry audio, video, or data signals over distances without the need for physical connections. The information is modulated onto a carrier wave, allowing it to be transmitted through the air to receivers. At the receiving end, antennas capture the radio waves and convert them back into usable signals. This technology is used in various applications, including AM and FM radio, television broadcasts, and cellular communication. Radio transmission enables wireless communication, making it essential for modern connectivity.
