Satellite Radio—Music Everywhere
by Anonymous
The US Federal Communications Commission (FCC) in 1992 allocated a spectrum in the "S" band for nationwide broadcasting of satellite-based Digital Audio Radio Service (DARS). Total four companies applied for a license to broadcast over that band. In 1997, two of the four companies were given licenses. CD Radio (now Sirius Satellite Radio) or Sirius Radio and American Mobile Radio (now XM Satellite Radio) paid more than $80 million each to use space in the S-band for digital satellite transmission.
Let’s see how Satellite Radio works. Working of Satellite Radio is quite simple. Ground stations transmit information to the satellites, Satellites bounce the information down to radio receivers on earth, and Radio receivers receive and unscramble or decode the digital data signal, which contains up to 100 channels of digital audio.
Literally, we all have been enjoying great music on radio since years. There is a vast array of radio stations in the country providing music to suit almost everyone. At home, at office and even our cars we have our favorite radio stations. But when you travel too far away from the source station, the signal breaks up and fades into static. Most radio signals can only travel about 30 or 40 miles from their source. On long trips that find you passing through different cities, you might have to change radio stations every hour or so as the signals fade in and out.
Now, imagine a radio station that can broadcast its signal from more than 22,000 miles (35,000 km) away and then come through on your car radio with complete clarity. You could drive from Tacoma, Washington, to Washington, D.C., without ever having to change the radio station! Not only would you never hear static interfering with your favorite tunes, but also the music would be interrupted by few or no commercials. And that is the beauty of the Satellite Radio.
