1. A communication system for transferring data between a remote workstation and a computer network through an earth-orbiting satellite including a transponder operating in a frequency spectrum including a plurality of data channels, said communication system comprising:
- a central hub gateway server directly connected to a computer network, said central hub gateway server including a plurality of modems, each of said modems being respectively assigned to a particular one of said data channels,a first satellite transceiver connected to said modems, said first transceiver comprising a satellite antenna and a means for modulating the frequencies of data signals from said modems to a satellite frequency band;
a remote workstation; and
a second satellite transceiver connected to said remote workstation, said second transceiver comprising a satellite antenna and a frequency modulating means;
said first and second transceivers both transferring data to and from said satellite such that data is transferred between said computer network and said remote workstation.

Abstract
A system for remotely accessing computer networks is provided in which a central hub is connected to a computer network. The central hub may then be connected to a plurality of remote sites through an earth-orbiting satellite. Users at multiple remote sites may be connected to the central hub simultaneously through frequency management techniques.
