Background Technology and Hardware Ubuntu Edunet is a private communication network based on satellite technology. The lesson or presentation is transmitted from the studio in Randburg to the satellite as a compressed digital video signal. This broadcast is addressed only to the classrooms that are selected and ready to receive it.
Students watch a large television screen.
No terrestrial lines are involved. A dedicated video channel between the studio and the sites is provided by the geo-stationary Intelsat 704 communications satellite. The footprint of Intelsat 704 covers the entire South and Southern Africa region. Ubuntu Edunet can be of service anywhere in and around South Africa. Gilat Communication Engineering which specialises in satellite communication, supplies the interactive software, the hardware for remote sites and the hub.
