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:
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 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 - continued below ...
