Satellites orbit above the earths surface. In the year 1962, the first signals were relayed from such a communications satellite. In North America, Canada was the first country to relay TV signals in the year 1962 through its satellite named Anik 1. The use of satellites to relay TV channels, Internet broadband and radio has become very common these days. These satellites enable the signals to be relayed over a large area. This increases market penetration enabling the TV channel service providers and Internet service providers to run a more efficient and profitable business. Satellite dishes work by receiving signals from an up linking center based on earth. The up linking dish is around 10 meters in diameter and directed towards the receiving satellite. The large diameter helps improve the quality of relayed data to the receiving satellite. The satellites have a device called transponder that receives and relays back the signal to earth at a different frequency. These signals are then received by thousands of households even in the most remote places. Dish satellites are costly but in the long run, they help generate additional business because of the extra features provided and this covers up the initial cost. Satellite dishes have made it easier for households to enjoy various television channels, surf the Internet and listen to endless music channels on radio. There are fewer disruptions, better picture quality and high-speed connectivity than there used to be, so consequently the number of people opting for satellite TV is increasing every year. A number of such satellites have been launched in recent years all over the world. The demand for satellite bandwidth is increasing due to newer TV channels being launched regularly. The ever-increasing demand for broadband is also a factor. In the future, the dish satellite business is expected to grow fast and offer even better services to the consumers. The days of frequent TV interruptions and poor image quality are certainly over with this innovation in telecommunications. |
