FM radio

What is fm radio in phone?

The Radio feature in smartphones allows users to listen to radio broadcasts directly on their devices without a separate radio receiver. This feature utilizes the built-in hardware components of the smartphone such as the antenna and the radio tuner to receive and decode radio signals.

The "Radio" feature in smartphones refers to the device's ability to receive and playback radio broadcasts in the FM (Frequency Modulation) and AM (Amplitude Modulation) bands. This functionality is made possible through the integration of a radio tuner chip within the smartphone's hardware architecture.

The radio feature operates by leveraging the smartphone's built-in antenna to capture the electromagnetic waves transmitted by radio stations. These waves carry the audio signals decoded and amplified by the radio tuner chip to listen to the broadcast content through the device's speakers or connected headphones.

FM (Frequency Modulation) Radio

FM radio is the most commonly used band for music and talk radio broadcasts.

It delivers superior audio quality and less susceptibility to interference compared to other bands.

FM radio stations broadcast in the frequency range of 87.5 MHz to 108 MHz with a channel spacing of 200 kHz.

AM (Amplitude Modulation) Radio

AM radio is primarily used for news, sports, and talk radio broadcasts.

It has a lower audio quality than FM but can transmit over longer distances.

AM radio stations broadcast in the frequency range of 530 kHz to 1700 kHz, with channel spacing of 10 kHz or 9 kHz, depending on the region.

Shortwave Radio

Shortwave radio is used for long-distance radio communication and international broadcasts.

It operates in the frequency range of 3 MHz to 30 MHz.

Some smartphones may support shortwave radio reception, although it is less common than FM and AM.
