Radiovågsspektrum

Radiovågsspektrum, also known as the radio spectrum, refers to the part of the electromagnetic spectrum that consists of radio waves. This range of frequencies extends from approximately 3 kilohertz (kHz) to 300 gigahertz (GHz). These waves are generated by oscillating electric charges and can propagate through space. The radio spectrum is a finite and valuable natural resource that is allocated and managed by regulatory bodies worldwide. Different portions of the spectrum are assigned for specific applications to avoid interference and ensure efficient use. These applications include broadcasting (radio and television), mobile communications, Wi-Fi, radar, satellite communications, amateur radio, and scientific research. The behavior of radio waves, such as their ability to travel long distances, penetrate obstacles, and be modulated to carry information, makes them essential for modern communication technologies. The allocation and regulation of the radiovågsspektrum are critical for enabling a wide array of services and innovations.
