Satellite Modem - Applications

Applications

Satellite modems are often used for home internet access.

There are two different types, both employing the Digital Video Broadcasting (DVB) standard as their basis:

• One-way satmodems (DVB-IP modems) use a return channel not based on communication with the satellite, such as telephone or cable.

• Two-way satmodems (DVB-RCS modems, also called astromodems) employ a satellite-based return channel as well; they do not need another connection. DVB-RCS is ETSI standard EN 301 790.

There are also industrial satellite modems intended to provide a permanent link. They are used, for example, in the Steel shankar network.
