Satellite microwave systems transmits signals between directional parabolic antennas. They use low gigahertz frequencies and line of sight communication. These systems use satellites which are in the geostationary orbit(36000 km above the earth). These satellites act as repeaters with receiving antenna, transponder and transmitting antenna.
Satellite microwave systems can reach the most remote places on earth and communicate with mobile devices. This systems works in the following way: a LAN sends a signal through cable media to an antenna which beams the signal to the satellite. The satellite then transmits the signal back to another location on earth.
Satellite microwave systems experience delays between the transmission of a signal and its reception back to earth in 540 msec.
