LinkStar: DVB-RCS Topology Star Satellite Communication System

LinkStarTM is a two-way broadband satellite communications system for Internet Protocol (IP) connectivity over satellite. LinkStar consists of one or more central stations - the hub -, many remote VSATs (Very Small Aperture Terminals), and appropriate management and control subsystems. The remote VSAT - called the Return Channel Satellite Terminal (RCST) - is a small, low cost terminal designed for multimedia broadband connectivity in networks with a large number of sites.

Because of the low cost of the remote terminal, LinkStar™ is an ideal solution for enterprises and service providers (e.g., VPNs and ISPs) that need broadband IP connectivity for multimedia applications over a large geographic area. A single hub can connect up to 10,000 remote terminals, and a multi-hub LinkStar system can integrate as many as 100,000 remotes into a single network.

Product Overview

LinkStar™ is designed to offer high-throughput connectivity between a large number of remote users and one or more hubs, configured in a "star" network topology. The connectivity is asymmetric, with a large capacity outbound satellite link from the hub to the remote terminals, and many medium capacity inbound satellite links from the remotes to the hub.

The LinkStar system consists of the following:
