Review on Satellite Communication

Abstract

Satellites are specifically made for telecommunication purpose. They are used for mobile applications such as communication to ships, vehicles, planes, hand-held terminals and for TV and radio broadcasting. They are responsible for providing these services to an assigned region (area) on the earth. The power and bandwidth of the satellites depends upon the selected size of the footprint, complexity of the traffic control protocol schemes and cost of ground stations. A satellite works most efficiently when the transmissions are focused with a desired area. When the area is focused, then emission does not go outside that designated area and thus minimizing interference to other systems. This leads more efficient spectrum usage.
