Satellite TV. This article may be considered science
fiction, just like Arthur C. Clark once had a scientific vision
about 3 satellites orbiting the earth in geostationary orbits to
make global communications possible. Everything in this article
is merely a scientific vision and an extrapolation of current
technologies into the future.

What would be the future of href="http://www.dish-network-satellite-tv.ws/">Satellite
TV? That may seem to be a difficult question, but
extrapolating what we know about the past into the future and
some educated guesses, we may very well end up with a reasonable
picture of what the future of satellite TV looks like. The
future of satellite TV will be guided by these properties:

Receive and Transmit
Equipment Size and
Costs
Satellite Capacity and Coverage
Antenna
Size
New Technologies

1 Receive and Transmit

What would be possible if you could not only receive, but also
transmit? And in the same bandwidth as you receive? That would
change the whole world. It is possible now to use the satellite
for Internet purposes, but in a very simple and inefficient way.
You receive via satellite, but transmit via phone. Upload
capacity is completely limited by the dial up connection.

The idea of being able to transmit to a satellite from your home
is new and will probably one day be reality. At the moment
companies can use satellites to connect offices all over the
country via satellite. Bandwidth is limited, or very expensive.
Another problem for home use is the size of the href="http://www.dish-network-satellite-tv.ws/">satellite
dish. At least 4 foot for small bandwidth and up to 10 feet
or even more for higher bandwidths. In point 3 this bandwidth
issue is explained in more detail.

2 Equipment Size and
Costs

Your satellite equipment at home may seem small, but it is small
because all it has to do is receive. Transmitting requires
different equipment. Not so much in the house, but on the roof
at the antenna there is need for a relative big transmitter.
Also these are still pretty expensive and for domestic use just
not affordable.

In the future this will change. Equipment
will get smaller, and cheaper. Eventually when satellites are
able to relay much more data than now (see point 3), having
10.000.000 transmitters on the ground won't be a problem.

3 Satellite Capacity and Coverage

This will always be the bottle neck of satellites; how much data
can they relay and how small an area can they cover. A satellite
has multiple dishes and each dish can cover a part of the earth;
small parts like just one state or big parts like the whole
continental United States.

In the future satellites will be
able to relay much more data, and cover much smaller areas.
Especially the smaller coverage areas will be important. Having
full capacity available for just a small area means higher
bandwidth available for a small amount of people. Especially in
urban areas it will be great to have a satellite cover just one
neighborhood.

4 Antenna Size

This is a very important issue. Small antennas of 18 inches
already exist, but these can receive only. The opening angle of
an antenna like this is too big to get enough signal power to
reach the satellite. In the future however, antennas will get
better and eventually small antennas can be used to transmit to
the satellite.

5 New Technologies

This will be the really interesting part. New technologies may
open up possibilities that are never heard of before.

Imagine watching a movie in 3D, you sitting on your couch but
watching a show as if you are in the audience when the TV show
was recorded. You're not really having a TV at home anymore, but
a 3D entertainment room. (for those of you who like StarTrek, a
not so strange idea). Normal Satellite TV will still be
available of course.

In the future href="http://www.dish-network-satellite-tv.ws/">Satellite TV
will open up so many possibilities that it is hard to imagine
what our lives will be like in 30, or even just 20 years from
now. To give an idea of how fast things are going. 50 years ago,
there was nothing in space that was made by humans. Now there
are even satellite graveyards (specific orbits where obsolete
satellites are "parked"). The possibilities of satellite TV
technology are growing faster every year. What took 10 years to
develop 30 years ago is now done in 2 years.

href="http://www.dish-network-satellite-tv.ws/">Satellite TV
is one of the driving forces for satellite technologies because
the need to please million of subscribers is much stronger than
the need to please the relative limited needs of communications
for commercial purposes. The future of satellite TV is so
bright, that a supernova would pale in comparison!
