Satellite radio is an entertainment medium that broadcasts digital signals through geostationary satellites. These satellites orbit the Earth in a synchronized pattern, which allows for a radio signal to be received and rebroadcast from any location.
It is a subscription-based service that allows subscribers to receive a vast number of channels. These channels typically include music, news, talk and sports programming.
Unlike traditional radio, which is a broadcasting system that requires a large antenna to transmit signals over a wide area, satellite radio uses small radio receivers to decode the digital signals transmitted by geostationary satellites. This system is known to offer a clearer signal and greater dynamic range than traditional radio.
The main players in the satellite radio market are Sirius and XM. These companies launched in 2001 and 2002, respectively, with a focus on exclusive content. WorldSpace, a company founded in the 1990s that served Africa and Asia, was bankrupt in 2009.
A radio that is “satellite ready” will automatically pick up the signal of one of the major satellite providers. This means that you can listen to your favorite stations anywhere in the United States without having to worry about being out of reception range.
There are many different types of satellite radio receivers. These range from a simple head unit that can be installed in your car to a portable receiver that can be carried into the house or even used outside of your vehicle.
Sirius XM has also introduced an optional backseat TV service that lets you watch television shows while listening to your favorite radio stations. This service works with several automobile manufacturers, and can be activated by simply pressing a button on the vehicle’s remote control.
