Satellite TV can be explained as TV broadcasts received through a satellite that is in geostationary orbit 22,000 miles above the Earth. An Earth TV station sends signals to the satellite, which are then relayed back to be received by a dish. Satellites are capable of delivering both analogue and digital services, but with the advancement in technology analogue transmissions are giving way to digital broadcasts.
In its early years satellite TV was quiet demanding in terms of the set-up costs, voluminous infrastructure and difficult lay-out. In comparison all that you need today is compact satellite dishes hovering on your rooftop.
Traditionally we have been using broadcast/terrestrial television method to broadcast signal delivery by radio waves transmitted through open space. Broadcast stations use a powerful antenna to transmit radio waves to the surrounding area. Cable TV is very similar to terrestrial television with the exception that the signal cable goes all the way to the provider where as terrestrial television goes over the air.
Both broadcast television and satellite television work wirelessly transmitting programs via radio signals. But broadcast television can work only within a limited range. Also radio signals are beamed out from the broadcast antenna in a straight line. Therefore to receive a perfect reception like you find on cable you have to be reasonably close to the antenna without too many obstructions.
Satellite television resolves the issues of range and distortion by transmitting broadcast signals from satellites orbiting the Earth. Being high up in the sky, they can cater to a lot more viewers.
