HOW THE SATELLITE TV SYSTEM WORKS?
Satellites operate in the microwave frequency range. This allows them the bandwidths necessary to handle several television channels and thousands of voice and data transmissions simultaneously. There are two major freq bands allocated for satellite communication; C-Band and KU Band. Section 3 gives broader info about these bands. In order o understand covering areas of the satellites followings needed to be known; Bore sight Point: Since both of the satellite’s antennas are directional, they both have a pattern. The center of this pattern, where maximum gain occurs, is called the bore sight point. Effective Isotropic Radiated Power (EIRP) : The pattern of the transmitting becomes particularly important when attempting to determine the strength of a satellite signal reaching the Earth. As the transmissions leave the satellite, they form a beam that covers a specific area of the Earth. The energy levels of this beam are called Effective Isotropic Radiated Power (EIRP), and they are dist
