Internet via satellite (also known as Satellite Internet) is a method of using Internet as a means to link a satellite. It recommended a system of access in places where not served by cable or telephone, as rural or remote areas. In a city represents an alternative to the usual, to avoid bottlenecks because of the saturation of the conventional lines and a bandwidth limited.

The signals reach the satellite from the ground station by the “make up” and sent to earth from the satellite by the “downlink”. To avoid interference between the two beams, the frequencies of both are different. The bottom beam frequencies are higher than the downlink because the higher the frequency produced greater attenuation in the signal path, and therefore it is preferable to transmit more power from the earth, where available energy is higher. To keep ahead of the downlink channels interfere with each other, are used polarizations different. Within the blocks there are satellite called transponders, which are tasked to receive, exchange and transmit frequencies of the satellite, so that the information sent from the base to reach the receiving antennas.

First note that the diameter of the dish is a function of the coverage area (footprint or footprint) of the satellite to give us access to the Internet. The surface of the antenna is a parabolic of revolution; all waves in parallel to the main shaft bearing are reflected and end up in the spotlight. Focus is centered on the parabolic. HughesNet is one of the best satellite internet providers in the present.
