Commercial FM radio operates within the frequency range of 88 to 108 megahertz (MHz), a segment of the Very High Frequency (VHF) band. This range was standardized to provide high-quality audio broadcasts, characterized by their ability to deliver clear sound with reduced interference compared to AM radio. FM, or Frequency Modulation, works by varying the frequency of the carrier wave in accordance with the audio signal, which allows for greater fidelity and a better listening experience. This band is widely utilized across the globe for various types of programming, including music, news, and talk shows, making it a cornerstone of modern broadcasting.
