HUBLESS BROADBAND NETWORKS VIA SATELLITE

LAN INTERCONNECTIONS, VIDEOCONFERENCING, TELEPHONY, TELECOMMUNICATIONS
INFRASTRUCTURE, BROADBAND MARITIME COMMUNICATIONS AND MUCH MORE

Incorporate your networking applications, whether IP, ATM, Frame Relay, or ISDN protocols, into one high-performing network using Eutelsat’s D-SAT service. With adaptive on-demand bandwidth and advanced coding, D-SAT, a hubless VSAT system, gives you broadband connections efficiently and cost-effectively. Save on transponder costs while seamlessly connecting your networking applications, in mesh, star, or multi-star hybrid topologies. Satellite capacity is offered on a pay-per-use basis for both landbased and maritime markets. All terminals are interoperable over C- or Ku-band Fixed Satellite Service (FSS) satellites. D-SAT is ideal for telephony, emergency networks, LAN/WAN interconnection, Internet access, Intranet, videoconferencing, telemedicine, Virtual Private Networks (VPNs), and the extension of GSM networks.

SYSTEM DESCRIPTION
D-SAT can be used in a maritime or ground mobile environment, using customer-supplied stabilized platforms. System acquisition and timing is automatic, using GPS, thus allowing for turn-key mobile networking.
The D-SAT Indoor Unit (IDU) contains one integrated IP port and two optional interface ports, supporting ATM, Frame Relay, ISDN and voice services. The plug-in interface ports can be upgraded in the field.

Terminal modems can operate in an asymmetric mode, for users such as ISPs. An integrated burst modem features fast frequency hopping for both transmit and receive. The terminal includes a console interface port for unit installation and maintenance, however D-SAT is designed for stand-alone operation and requires no local operator control. Remote sites can be configured and monitored using either the over-the-air satellite connection, or by dialing-in with an external modem and analog line. The VSAT terminal includes a radio frequency transceiver (RFT) consisting of C- or Ku-band radio equipment, along with an antenna and mounting hardware.
