Radiokommunikációban refers to the field of radio communication. This encompasses the transmission and reception of information through the use of radio waves, which are a form of electromagnetic radiation. Radio waves travel at the speed of light and can propagate through space, the atmosphere, and even some solid objects.

The fundamental principle of radio communication involves generating radio waves at a transmitter, modulating them with information such as voice or data, and then broadcasting them. At the receiving end, a radio receiver captures these waves, demodulates them to extract the original information, and then presents it to the user. This process is facilitated by antennas, which are essential for both transmitting and receiving radio waves.

Radio communication has a vast array of applications. It is crucial for broadcasting, enabling radio and television services to reach wide audiences. It is also fundamental to mobile telephony, allowing for wireless conversations. Other key uses include radar systems for detection and navigation, satellite communication for global connectivity, wireless networking (Wi-Fi), and amateur radio for hobbyist communication. The frequencies used for radio communication are allocated and regulated by international bodies to prevent interference and ensure efficient use of the radio spectrum.
