What is satellite communication? How has it brought revolutionary changes in the field of communication in the world? Explain?

Explanation

Communication through satellites which emerged as a new area in communication technology is called satellite communication. It has brought revolutionary changes in the field of communication in the world. Artificial satellites are successfully deployed in the earth.s orbit to connect even the remote corners of the globe with limited onsite verification. These have rendered the unit cost and time of communication invariant in terms of distance. This means it costs the same to communicate over 500 km as it does over 5,000 km via satellite.
