stands for "Very Small Aperture Terminal", this term refers to any small fixed satellite terminal that is used to provideVSAT dish antenna interactive or receive-only communications.

The VSAT comprises of two modules: an outdoor unit and an indoor unit.

The outdoor unit consists of an Antenna and Radio Frequency Transceiver (RFT). The antenna dish size is typically from 75 cm to 2.4 m in diameter.

The indoor unit functions as a modem and also interfaces with the end user equipment like PCs, LANs, Telephones or PABX.

They are used for a wide variety of telecommunications applications, including corporate networks, rural telecoms, distance learning, telemedicine, disaster recovery, ship-board communications, transportable "fly-away" systems, and much more.

VSATs are becoming increasingly popular, because they are a single, flexible communications platform that can be installed quickly and cost effectively to provide telecoms solutions for consumers, governments and corporations.


VoicEvolution® complements its offer by delivering VSAT based solutions in the following applications:


  • Broadband IP networks for LAN interconnections (VPN) with MPLS capability
  • Videoconferencing, VoIP telephony and Fax over IP (Bandwidth on demand)
  • Maritime communications
  • Offshore oil platforms communications (in presence of potentially explosive atmospheres)
  • Interactive Distance Learning (IDL)
  • SCADA control and monitoring in the Oil and Gas industry (in presence of potentially explosive atmospheres)

All the proposed solutions  follow the internationally adopted DVB-RCS open standard architecture for 2-way VSAT networking.

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.

A revision of the DVB-RCS standard added support for the new DVB-S2 transmission standard, including adaptive coding and modulation features.

All these advanced features are supported by the VoicEvolution® solutions.

The network consists of a central earth station Hub station, the communication satellite, and VSAT terminals at the remote sites.
