Satellite Radio
(Communication)
What Is Satellite Radio?
Satellite radio is often considered one of the biggest improvements in
broadcasting since the introduction of the FM band. Satellite radio is
also called subscription radio or pay-radio because it is only available
trough subscription to one of the satellite radio providing companies.
Satellite radio follows a concept similar to cable television by
providing a very wide range of programs which are not available in the
traditional FM or AM format for a fee.
Satellite radio uses satellites to deliver radio programs to
subscribers. The radio signal is broadcasted from Earth based stations
to communicational satellites, which then redirect the signal to
satellite radio receivers. The radio signal is broadcasted by
communication satellites to a much larger area than traditional
terrestrial radio antennas.
For example, satellite radio is available al across the continental area
of the United States. Satellite radio is available now in most parts of
the world trough services provided by companies like WorldSpace (in
Europe, Asia and Africa), Sirius and XM Radio (in North America). The
radio signal you receive using satellite radio is digital, which means
that it is always clear and static-free, which is one of the great
advantages of satellite radio. Another great thing about satellite radio
is that it is almost completely commercial-free.
To begin listening to satellite radio you will need the actual satellite
radio (also known as tuner or receiver), a satellite radio antenna
(which is often incorporated in the satellite radio) and a subscription
to the service you choose. There are several types of satellite radio
from which you can choose. One of them is the dedicated car or home
radio, which play trough your car or home stereo.
A second option is the plug-and-play radio, which can be used in your
car, as well as in your home by paying a single subscription. Your third
option is the portable radio, which has rechargeable battery, a built-in
antenna and you can listen to it wherever you go using headphones. The
radio signals offered by different satellite radio companies are
proprietary, which means that you will need different hardware for
receiving, decoding and playback, depending on your subscription.
Each satellite radio receiver has its own serial number called Radio ID.
When you get your subscription, you will also get an activation code for
your receiver. Besides the actual radio programs, satellite radio
transmits metadata that contains the name of the artist, the title of
the song or program, as well as the name of the channel. This makes it
easier for you to decide which channel to listen to and which program to
choose.
Satellite radio services provide the subscriber with more than 100
programs that vary in content from rock and jazz to rap and classical
music. But satellite radio’s utility reaches far beyond listening to
your favorite music without the interruption of those annoying
commercials.
Satellite radio also offers exclusive sports programs, cultural and
educational shows, news and talk-shows. Some of the celebrities that
have moved their shows from free radio to satellite radio include Howard
Stern, Opie and Anthony, Bob Edwards and Martha Stewart. Unlike
terrestrial radio, satellite radio is not affected by bad weather or
even calamities.
At first, many people wondered why they should pay for radio if they can
get it free. However, satellite radio attracts more and more people
every year due to its great advantages: no commercials, extensive reach,
theme programs and exceptional quality of sound
