Satellite Networks

The use of satellite networks for data/signal transmission is the major advancement in telecommunication technology. Communication satellites have facilitated the transmission of microwave signals over very long distances. This communication covers maximum area on earth for a particular transmitter. The satellite receives data/signals from one earth station. Amplifies them and sends them to the other earth station. The earth station consists of satellite dish that functions as an antenna and communication equipment to transmit and receive data from satellites.

A number of communication satellites, owned by both government and private organisations, have been placed in stationary orbits. These satellites orbit in the space 22,400 miles above the earths surface and serve as microwave relay stations for the microwave transmitters located on the ground. Most communication satellites have multiple, independent reception and transmission devices known as transponders. Communication satellites have some interesting properties that make them attractive for many applications. In its simplest can be thought of as a big microwave repeater in the sky.





Disadvantages of satellite Network

Some of the disadvantages in the use of satellite networks are:

  • It is very expensive. It can be suitable if the organization need is huge.

  • Since the satellite transmission is all around the world, therefore, this communication is an insecure communication.

  • The satellite needs synchronization with the speed of the earth.

  • Risk of failure is high.

  • Extreme length of the transmission path between the sender and the receiver may cause delay of signals.

  • A signal delay caused by the extreme length of the transmission path between sender and receiver.
