Frequency modulation radio (FM radio) refers to a wireless communication technology that can transmit audio signals within a specific frequency range. FM broadcasting bands generally refer to the frequency range between 87.5 MHz and 108 MHz. This frequency band belongs to the FM frequency band in radio, hence the name FM broadcast band.

The coverage area of ??FM broadcasting is much smaller than that of medium wave broadcasting. If conditions are right, the range that an FM radio transmitter can cover is usually limited to tens of kilometers or even less. Moreover, this radio wave will be blocked by reinforced concrete and other buildings, causing the signal to weaken or disappear. But at the same time, because of this characteristic, the signal quality in the FM broadcast band is relatively stable and clear, and is not susceptible to interference.

Currently, FM broadcast bands are widely used, including various types of music, news, sports, entertainment and other programs. Among them, music programs are the most popular because the FM radio band has advantages such as high sound quality and rich program content compared with other media. In addition, the radio station will also produce programs with different themes, such as current affairs commentary, psychological counseling, literary theater, TV drama translation, film music, etc., to meet the needs of the public.
