A satellite orbits at an altitude of 22,300 miles above the earth, the altitude that cause it to stay in a fixed position relative to the rotation of the earth. This is called as a Geostationary orbit.
In satellite communications a ground station on the earth will send and receive signals from the satellite. The signals will have propagation delays ranging between 0.5 to 5 seconds due to the distances involved. The transmission frequency will normally be in the ranges of 10 to 15 GHz with a transmission speed in the range of 1 to10Mbps. GEOs can cover as much as a third of the earth's surface.
Satellite Internet services can be used in locations where physical Internet access is not available and in devices that move frequently.
Internet access via satellite is available in most parts of the globe, including remote areas like forests and to ships at sea.
