Little would have our ancestors thought that communications as a whole would develop at such a rapid pace that today we have been blessed with all-round connectivity anywhere in the world. The growth of communication has really reached its benefits to all major spheres, keeping the entire globe connected together. It is only due to the progress made in the field of communication that different nations could develop close affinities with one another and live in peace.

It has been a prolonged journey from ancient times when messages could hardly be exchanged in time, resulting in loss for everyone. But communication gradually progressed making it a little more convenient to communicate with each other through use of non-electric means. However, it was the invention of telecommunication that really enabled us to transmit messages from one place to another. Today, it has gained extensive access with the inclusion of electric means like telegraph, telephone and internet.

Mobile and wireless communications are involved in providing voice and data communication to cell phones and internet terminals. While first and second generation cellular systems are already in place, 3G and 4G systems are on the pipeline to achieve further higher data rates. Mobile and wireless communication is also serving as the subject for research for students on topics like social effect of mobile communication.

It is the advancement made in satellite technology that really revolutionized the communication world with satellite dishes dotting the landscape everywhere and satellite wireless phones and Internet services providing solutions to link remote geographical locations, connecting every nook and corner of the universe.

Telecommunication networks link different terminal users with each terminal in the network, with a separate identity, sending and receiving messages like in computer and internet networks.

The advancement of communications has taken place at such a fast pace that the present generation cannot think of being without any of them. The technology has come to be part and parcel of almost every day-to-day activity, be it in educational institutions, business houses, sports, arts or various forms of entertainment.

Direct Broadcast via Satellite (DBS) delivers satellite television service where satellite TV providers use satellites on the ground and in orbit. Communication Satellite is an artificial satellite commissioned in space to facilitate telecommunication functioning.
