The Very Small Aperture Terminal (VSAT) is a satellite communications system that is used to connect remote sites to International hubs in order to access the internet or share data within a company system. Satellites are used when a terrestrial solution is not conceivable and when it is also not possible to connect two points directly with antennas, because they are too far and it is not possible see each other. In this case, the better way is to have a satellite connecting the two points, it works like a mirror, it reflects the signal from sender to receiver and back.<\/p>\n

The satellite can only cover a part of the world, like we see in the image this below:<\/p>\n

Commercially talking, we have different products (different bands of frequency). It depends on the needs of the customer.<\/p>\n

\u2013 C-Band: (Frequency range 3-6GHz) It is the most stable solution with the highest average of network availability. The antennas dishes are also the biggest ones (from 1.8 meters to 3.6 meters). This is the perfect solution for big projects.<\/p>\n

\u2013 Ku-Band: (Frequency range 14-16GHz) For this one, we propose 3 different types of antenna.<\/p>\n
