SATELLITE RADIO
satellite radio.pptx (Size: 431.01 KB / Downloads: 75) Introduction Satellite radio is an analogue or digital radio signal that is relayed through one or more satellites and thus can be received in a much wider geographical area than terrestrial FM radio stations. While in Europe many primarily-FM radio stations provide an additional unencrypted satellite feed, there are also subscription based digital packages of numerous channels that do not broadcast terrestrially, notably in the US. In Europe, FM radio is used by many suppliers that use a network of several local FM repeaters to broadcast a single programme to a large area, usually a whole nation. Many of those have an additional satellite signal that can be heard in many parts of the continent. System design Satellite radio uses the 2.3 GHz S band in North America and generally shares the 1.4 GHz L band with local Digital Audio Broadcasting (DAB) stations elsewhere. It is a type of direct broadcast satellite and is strong enough that it requires no satellite dish to receive. Curvature of the earth limits the reach of the signal, but due to the high orbit of the satellites, two or three are usually sufficient to provide coverage for an entire continent. Satellite Radio Units Not unlike an mp3 player or GPS, a satellite radio receiver is a small LCD display that is wired to an antenna that receives the satellite signal. There are models for your car, your home or your boat, or to carry with you, but all are basically the same. Can get home stereo receivers that are satellite-ready and will show you the satellite program information on its display. There are also a wide array of cars and trucks that come with radio satellite capabilities built in. The Delphi satellite radio was the first unit produced to receive the signals, but lots of manufacturers are producing them now. Satellite Radio Channels The breadth of programming available on satellite radio is what makes it so outstanding. For sports fans, almost every single game of most major leagues is broadcast live. For news junkies, numerous international outfits have satellite channels, delivering up-to-the-minute information and analysis. If you love to laugh, the exclusivity of some of the comedy channels and the uncensored nature of their content will have your sides splitting in no time. Advantages of satellite radio One of the great advantages of satellite radio is the fact that the programs are not interrupted by commercials. Satellite radio tuners receive, along with the actual radio programs, an influx of metadata that consists of information regarding song title, artist, radio program and radio channel. Satellite radio programs also offer information about local traffic and weather conditions. Satellite radio is great for you especially if you travel a lot. Disadvantages of Satellite Radio Satellite radio can broadcast over an enormous range. Many people enjoy the service for its very specific music genre channels, talk radio channels featuring politics and sports, and few or no commercial interruptions. Satellite radio does come with a few disadvantages, however. Non-Local Signal Limitations Signal Interruptions Receiver Purchase Subscription Fee |
