Sirius radio or a more general satellite radio just came out a few years ago. If you have never heard or heard of satellite radio, this article is a lucky break. In this article you will find out what satellite radio is working and how it works.
What is satellite radio?
As the name suggests, satellite radio uses satellites and related equipment to transmit radio waves to car or home radios. The concept gained momentum in 1992 when the FCC neglected a radio frequency radio called Digital Audio Radio Service (DARS). Five years later, Sirius Radio and XM Satellite Radio purchased a license from the FCC and both companies began to place the pieces to start broadcasting.
Traditional radio waves can only travel 35 to 45 miles before they die. The signaling of satellite radio services covers more than 20,000 miles on Earth's surface. Programming on satellite radio is subscriber-based, that is, a monthly fee to give you a signal from the satellites. But most satellite radio services are commercially free, so you do not have to worry about channel leakage. Channels include music, talk radio, sports events, kids programs and news.
The Who's Satellite Radio
There are currently three major players in the satellite radio game: Sirius Radio, XM Satellite Radio and WorldSpace. Sirius radio extends to North America, including continental USA, Canada and Alaska. XM provides services in the continental United States WorldSpace develops coverage in other parts of the world (Asia, Africa, Europe and South America) and is strictly the most ambitious for customer coverage (4.6 billion potential customers on 5 different continents). Each company uses different satellite technologies and methods to provide services within their own territory.
Satellite receivers, such as car receivers and home stereo appliances, are being sold in a number of consumer electronic stores and become standard equipment in new cars. Traditional radios can not receive satellite radio, so service delivery usually involves purchasing a receiver, although there are some kits that allow the compatibility of conventional radio-satellite radio-controlled radios.
Due to the different technologies used by companies, customers are not compatible with any company. For example, if you subscribed to the XM, but then want to switch to the Sirius radio, you will need to receive a new Sirius-compatible receiver. Some satellite television companies include satellite radio services in their channel packets and can receive broadcast via the satellite receiver of the television.
How does satellite radio work?
This is the cool part. Music, talk shows, sports events, etc. Digitally recorded in a studio after which the message is encoded. The encoded signal is transmitted to ground stations by satellites (Sirius radio in New York, XM based DC). The satellites then transmit the signal to receivers in the car or at home. Customers include chips that decode the signal and play stereo. In urban areas where higher buildings block signals from satellites, terrestrial transmitters or transmitter units are used to resubmit the signal, eliminating dead space.
XM uses two satellites to cover the continental United States with the flag. The Sirius radio uses three satellites to create a satellite constellation. Their pitch ensures that each satellite at one time spends about 16 hours in the United States and that there is always at least one satellite in the United States at a given time. WorldSpace satellites broadcast three signals to increase their territory, which they can cover with their three satellites. All three companies are available to make available satellites if one of their satellites stops.
Satellite radio technology looks like it's here. Ideal for those who live in places where normal radio reception is poor or for those who are willing to pay monthly without having to listen to commercials. There is a good chance that soon every new car will buy satellite radio and will be more and more home. I just discovered the basics. Definitely worth the time to find out more about what some companies offer.
