Satellite radio is a type of radio broadcasting that uses satellites to transmit audio signals. Unlike traditional radio, which relies on terrestrial towers, satellite radio provides a wider coverage area, allowing listeners to enjoy a consistent signal even in remote locations. Listeners typically subscribe to a satellite radio service, which offers a variety of channels featuring music, news, sports, and talk shows. Popular providers include SiriusXM, which offers numerous programming options and the ability to listen in vehicles, homes, and on portable devices.
