The help of Satellites

Satellites helps earth and everyone on it to communicate to others around the world. According to the article "How Satellites work", it states that, "modern communications satellite receives the radio signal and sends it back down to Earth stronger than it was received. This process is called "amplification" of the radio signal. In addition to amplifying the signal, a communications satellite also typically converts the radio from one frequency to another so that the signal getting sent down is not confused with the signal being sent up." Meaning that it helps spread the word around without going around. It is the way we listen to the radio, watch television, get internet and etc. Without satellites we would have no technology today or be very behind in technology upgrade. If we didn't have satellites I believe everyone will be more active and less time sitting down being lazy.
