Satellite radio history:

Satellite radio is more than a decade-old idea. In 1992, the US

The Federal Communications Commission (FCC) has allocated spectrum

"S" band (2.3 GHz) for satellite based broadcasting

Digital Audio Radio Service (DARS). Only four companies have requested a

grants permission to music. The FCC has granted permissions

of these two companies in 1997. CD radio (now Sirius Satellite Radio) and

American Mobile Radio (now XM Satellite Radio) paid over $ 80 million

in the S-band for digital satellite transmission. The first satellite radio launched by XM on September 25, 2001, followed by Sirius on July 1, 2002.

There are currently three spatial radios:

    Sirius Satellite Radio
    XM Satellite
    Radio
    WorldSpace Satellite Radio

The importance and significance of satellite radio:

We all have favorite radio stations,

radios that move between each other when working and working on duty

and around the city. But if it is too far from the source station, a

the signal becomes torn and becomes static. Most radio signals are only approx

or 40 miles from their source. On long journeys that are moved

in different cities, you may want to change the radio stations every hour or so that the signals fade

and who. Now imagine a radio station that emits a distance of over 22,000 miles (35,000 km) and then becomes fully transparent on your car radio. You could drive

almost hundreds of miles without ever having to change the radio station! No

would only hear you statically disturb your favorite melodies, but

the music is limited or no commercial breaks.
