DVB-RCS Network Overview

A DVB-RCS VSAT network is a satellite-based communications system that provides interconnection between users who are exchanging real time (and non-real time) applications based on several data types (e.g. text, voice, images, video etc…). There are two transmission paths, the Forward Channel from a centralized Hub location to the remote location and a Return Channel from the remote location to the central Hub.

The DVB-RCS VSAT system underwent final standardization by the European Telecommunications Standards Institute (ETSI) in 2000. The standard calls for a forward link based on a DVB/MPEG-2 data format and a return link using Multi-Frequency – Time Division Multiple Access (MF-TDMA) scheme, allowing a two-way exchange of data. The DVB/MPEG-2 format carries from 1 Mbps up to 45 Mbit/s in the forward link and the MF-TDMA scheme allows from 64 kbps up to 4 Mbps per carrier.

A recent revision of the DVB-RCS standard added support for the new DVB-S2 transmission standard, including adaptive coding and modulation features. Support for these features are incorporated in Advantech Wireless’ products.
