Pure satellite links (2-way satellite connection) are available practically independent of geographical features or other infrastructure all over the earth's surface and are therefore particularly suitable for remote areas and ships. Are a problem in satellite access the still significantly higher cost, high-latency, unless the return channel is realized via the satellite, the dependence of a further means of access.
In the example of a system with geostationary satellites typical delays of 500-700 ms, which disturbs sensitive real-time applications arise. The technique enables transfer rates of 1-2 Mbit / s and more. The capacity is limited in Germany to some 10000 simultaneous users, however, should be expanded
