Title: Telecommunication Specific Purpose: To inform my audience about the AT&T’s contribution to telecommunication industry. Thesis Statement: AT&T’s innovative development of the transatlantic radiotelephone and communication satellite changed communication and inspired new inventions that would shape the future of the world. INTRODUCTION I. Attention Getter: The first time I came to the United States‚ I was so excited to share the beautiful sceneries with my family that

allowed the society’s teens to have inane communications and in doing so‚ contributes to the ‘dumbing down’ of society. We spend more time corresponding with our friends on cell phones and the Internet than we do working or participating in activities which expand and challenge our minds. Our fixation with technology makes us oblivious to the social implications. Teens today are lacking basic social skills because of an absence of face-to-face communication assisted by this technology. On average

“computers” or “ice cream.” While these may be important‚ they are definitely not the most important. By far‚ satellites are the most important objects today. Most everything‚ including smartphones and computers‚ are present today because of satellites and have capabilities such as Wi-Fi and 4G because of the role satellites play. Even Socrates‚ who lived centuries before the first satellite‚ realized the importance of a view from space when he said‚ "Man must rise above the Earth…to the top of the

VSAT-VERY SMALL APERTURE TERMINAL The 1980s began the rapid introduction of new satellite services and new participants in satellite communications. Nearly 100 countries were involved in satellite communications – providing either satellite systems or satellite-based services. This decade also saw the advent of new and innovative ways to pay for the high costs of satellite systems and services‚ including lease/buy options‚ private networks (often referred to as very small antenna terminals

The bus is the part of the satellite that carries the payload and all its equipment into space. It is the physical platform that holds all the satellite’s parts together and that provides electrical power‚ navigation‚ control and propulsion to the spacecraft. The bus also contains equipment that allows the satellite to communicate with Earth‚ a kind of ’remote control’. Satellite communications spectrum The satellite transmission bands that are of interest to us are the C-‚ Ku- and Ka-bands

How does a VSAT network work? A VSAT network has three components: • A central hub (also called a master earth station) • The satellite • A virtually unlimited number of VSAT earth stations in various locations - across a country or continent Content originates at the hub‚ which features a very large -15 to 36-foot (4‚5 -11m)- antenna. The hub controls the network through a network management system (NMS) server‚ which allows a network operator to monitor and control all components

helped develop- satellites and electronics. Satellites are a major component of the space program. So‚ the space program funded research that led to major advances in the satellite technology. In addition‚ to allow increased capabilities over small space and to reduce launch cost‚ the space program was pushed to develop integrated electronic circuits. This has led to the miniaturization of electronic components. These developments have led to the launching of numerous satellites that are currently

advances that have greatly affected America such as computers‚ cell phones and even satellite services. But‚ I think the most important of all technological advances would be the space program. Without the technology gained from our space program‚ all the other items would have never happened or would have taken a lot longer to be developed. It all began in the late 1950’s with the launch of the Russian satellite Sputnik. Prior to that most Americans assumed that the United States was superior
