Satellite radio is broadcast over clear, static-free digital signals from orbiting satellites. It offers a wide variety of programming, including music, news, talk and sports programs. Many channels are free of commercials and can be streamed directly from a portable receiver.
How it Works
A digital signal from a satellite is transmitted to a special antenna on your home, car or portable radio. The antenna receives the radio program, which is then played back through a speaker.
The sound quality of satellite radio is comparable to that of a CD player, but it is much more powerful. A digital compression process allows the service to transmit more sound with less bandwidth.
How It Works
In 2008, Sirius and XM Satellite Radio merged to form one company, Sirius XM. This merger was designed to avoid bankruptcy and to offer more programming choices to consumers.
Until 2007, XM was the only major satellite radio provider in the United States and Canada. It operated two geostationary satellites in elliptical orbits that provided coverage throughout North America and parts of Canada.
Sirius partnered with several automobile manufacturers to create a service that enables drivers to listen to a variety of Sirius stations while driving in their vehicles. The Sirius Backseat TV service was also launched in 2007.
The service is available for most cars equipped with a factory-installed satellite radio tuner. It can be used to listen to Sirius and XM radio stations in your car, as well as streaming music or video from your home. It can also be controlled by your car’s navigation system or a SiriusXM-enabled app on a mobile device.
