FM Transmitter


An FM transmitter allows a phone to broadcast music stored in its memory on FM frequencies, so that it can be tuned into a nearby FM receiver such as a a car radio.

FM transmitters are not a common feature on mobile phones, but such modern models do exist. The mobiles transmit at low power so interference with regular FM radio stations is highly likely especially in dense urban environments where most of the FM spectrum is already populated by live radio broadcasts.

Some embedded FM transmitters allow for transmitting the music details over RDS.
