Broadcasting digital radio via satellite is not something new
and concepts of doings this have been with us for a few years. From the early
days of satellite radio, companies like Dish Network have offered digital audio
channels as part of their programs. The breakthrough in popularity of satellite
radio, however, happened just recently, when the technology became more
permissive. Satellite radio was very rare on moving locations, such as boats or
cars, mostly because there was the need for some expensive equipment – a
tracking dish. This was a strong deterrent which kept satellite radio quite
unknown by the general public. Today, however,
one can receive digital audio satellite broadcasts by using a small,
GPS-like antenna. This greatly increased the feasibility of the satellite radio
systems and more and more vehicle owners began considering satellite radios as
a good source of music and news.
The birth
of satellite radio in the United States
When the U.S. Federal Communications Commission (FCC) allocated
a spectrum in the "S" band (2.3 GHz) for the broadcasting of digital
radio services in 1992 no one thought the amplitude that the system would take
in the future. From the initial Digital Audio Radio Service (DARS) things
progressed until two companies were given licenses to broadcast digital radio
in 1997. These two were American Mobile Radio (today known as XM Satellite
Radio) and CD Radio (presently called Sirius Satellite Radio). The fact that
satellite radio is nationwide makes it a very attractive media channel, both
for commercial and non-profit organizations. The two companies that initiated
the development of satellite radio saw the huge potential it had, since it
wasn’t confined by the limitations of other terrestrial broadcasters.
Benefits
of using satellite radio
Here are some of the most noteworthy benefits of having a
satellite radio system :
·
No more
geographical limitations – since the radio program is broadcast through a
satellite you don’t have to switch radio stations every time you leave a
certain coverage area.
·
The
digital quality of the satellite radio has some amazing benefits on its own.
There are no noise disturbances that were traditional to FM and AM broadcasts.
The transmission is crystal clear and satellite radio receives some valuable
points when broadcasting quality is concerned.
·
Analog
radio stations simply cannot broadcast the full range of sounds available
through digital satellite radio.
·
Both XM
Radio and Sirius Radio can be picked up on all the US territory and they are
also available in some parts of Canada and Mexico.
Satellite
radio technology
Each of the major satellite radio services uses its own
equipment to broadcast the signal to their clients. The competition is tight
and customers have to “pick sides” in order to benefit from satellite radio
broadcasting. You have to choose your preferred company and purchase adequate
receivers for that particular company.
Both XM Radio and Sirius Radio provide their clients with different ways
of receiving their services. The field where most competition takes place is in
the negotiation with the major automobile manufacturers. Both XM Radio and
Sirius Radio have deals with the auto industry giants in order to offer their
services and equipment as optional on the car models they produce. Other
partnerships were created with audio equipment manufacturers, who now offer
satellite radio transceivers and matching headsets. The most recent shock in
the satellite radio universe was caused by the production of portable MP3
player-like satellite radio receivers.
The future
development of satellite radio
One of the main problems of satellite radio was addressed by the
main satellite radio broadcasters. Since you need to be in the line of sight of
the satellite to receive the transmission, different problems appeared with
mobile satellite radio receivers, especially when different landscaping objects
blocked the direct transmission. To solve this, land based devices were
installed in order to eliminate the lack of direct satellite transmission.
Another interesting aspect related to satellite radios is that they approached
their service offers from a different perspective than traditional radio
broadcasters. Instead of airing commercials they charge a subscription fee. For
many people, this is actually the best alternative, since they get an almost
100% content broadcast (whether it’s music or talk shows) without the 10-12
minutes per hour of annoying commercials. In most cases, the monthly
subscription for satellite radio is of around $12.
