There are no satellites in modern households, unless one considers teenagers, who generally orbit around the house without ever really being seen 'in' the house and more often than not seem to be dwelling in outer space. Without being in the house, satellites played and continue to play an important role in our homes.
Artificial satellites that are specially designed for communication are known as communication satellites. Satellites can have many applications such as TV and Radio Broadcasting, communication with ships, planes, submarines, and hand held satellite cell phones.
A tv guide can help us find what programmes are going to be on which day and at what time, but how are so many channels and programmes broadcast across the world? There must be some way to send all this information. Satellite TV is one of these ways.
Cable TV sends its signal through actual cables, while satellite TV sends the signal from a dedicated satellite orbiting the earth. Today, paid satellite TV services are digital signal broadcasts. This signal is captured by a dish antenna and transmitted to the TV.
Cell phones are ubiquitous today but are not satellite phones. Most places that are connected with landlines and cellular networks do not need to rely on satellite communications. However, places that are unconnected and locations such as ships or planes can only be contacted through satellite communication.
