The Future of Satellite TV

If you have Dish Network or thinking about getting it or another
satellite TV service, it's good to know what the future holds
for satellite TV. So, here's a glimpse into the future.
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 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:
1. Receive and Transmit 2. Equipment Size and Costs 3. Satellite
Capacity and Coverage 4. Antenna Size 5. 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 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 Dish Network or Satellite TV
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 and are used by satellite TV providers
such as Dish Network, 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 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.
Dish Network and 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!
