If a microwave radio link is set up transmitting to a telecommunications satellite in a high, geostationary orbit and the satellite receives the microwave signals, converts them and transmits them back to earth, large distances can be covered without the use of cables.
Si un faisceau hertzien est dirigé vers un satellite de communication stationnaire sur orbite haute, satellite qui reçoit, transforme et renvoie les signaux hertziens vers la terre, il est possible de franchir de grandes distances sans utiliser le câble.
