Satellite radio is an entertainment medium that uses satellites to collect and beam signals to terrestrial receivers. A standard AM-FM radio in your car receives signals from ground-based transmitting towers. On the other hand, a satellite radio receives its signals from geostationary satellites in space.
A geostationary satellite always positioned over the United States can easily transmit signals over the entire country. These radios contain receivers that receive data from satellites in space. The most significant advantage of owning such a radio is that you will never go out of the range of the radio signals.
With access to near-CD quality digital audio, without static or fading signals, you will enjoy constant access to your favorite stations when driving. However, environmental or man-made obstructions can temporarily block your reception of satellite transmissions.
These devices also help you enjoy customized entertainment. This radio service is usually available upon paying a nominal monthly subscription fee along with additional charges for enjoying access to specific genres and channels. The dominant satellite radio service in the U.S. is SiriusXM.
Almost all luxury car manufacturers have included these radios as a part of the standard accessories.
Non-luxury carmakers also often offer satellite radio as an optional feature alongside other high-end car options and accessories.
