6. The word ‘ Communication ’ comes from Latin word ‘ Communico’ - meaning ‘ share ’ . It is communication more than anything else which has been responsible for the shrinking of time and distance and with the development of space technology time and distance have lost their conventional meaning, permitting men and women all over the world to share their experiences, frustrations and successes. Present day the world has become a GLOBAL VILLAGE . Man is in a shrinking Globe and expanding Universe . Society is often described as essentially people in communication - Communication in simple terms is nothing but discriminating response to a stimulus. The " quickness of the response " is increasing in leaps and bounds day by day.

8. In the past few decades, persons and institutions have been progressively unsettled by the rapid pace of social and technological changes brought about by Communications (telephony, TV etc.). In earlier times the world around us seemed more stable and major changes in values, institutions and technology evolved more slowly. It took centuries for the Middle Ages to become the Renaissance , yet many of us have experienced major technological revolution in one life time in the last century.
9. Many technological reversals have been seen like the telephone which should have been on the wired network has become wireless, while the TV which was wireless now works on cable. Many individual spheres of working have become almost universal, like education has come to the drawing room from school and colleges, sectors like banking, medicines, hospitals etc which were location specific are available on net. There is tremendous convergence and fusion of communications, computers and associated technology in the present era.

11. We are presently getting on the crest of the third wave which is INFORMATION & COMMUNICATION REVOLUTION more appropriately termed as ‘IT ’ -Information Technology, the first being agriculture & the second being ‘Industrial Revolution’. As we become increasingly networked, our worlds will grow smaller and bigger simultaneously.

18. Before one goes ahead with communication satellites, it will be quite important & relevant to talk about latest arrival on the communication technology scene: the INTERNET & THE WEB. Internet the new incarnation of mass communication is becoming quite popular. Internet the parasite which has almost eaten away the host - the telecom channels, is influencing our every sphere of life.
19. Internet which we know today has come to Asia a couple of years back and in 2000 to India also will play an important role at least till 2015 AD. The internet provides a vast array of services and acts like a multimedia system, information resource and ways to perform work and engage in commerce. It has an estimated 600 million users which gets doubled every year. The safest prediction is that by 2015 the Internet, as we know it, will no longer exist. There will just be the Net a ubiquitous, broadband data dial-tone provided by a cable telephone, wireless or satellite operators.
20.
21. The changes won't occur in isolation, but they will be going on simultaneously, resulting in unpredictable, unanticipated synergy. In turn, this will lead to truly profound changes in society & the present technological paradigm. To help all these & to spread the net at a faster pace even to inaccessible & remote places Satellite Communication plays a major role, besides the conventional terrestrial links, optical links etc., which cater to cities and larger population bases owning to the economics.
22. Having talked about INTERNET let us come back to space communications. The most popular one is going to be: MOBILE PERSONAL COMMUNICATIONS

The telecom sector has grown very rapidly and we have a strong committed to make the benefits of telecom reach the masses through indigenous efforts. We look forward to Indian scientists and engineers like you to make this happen.
