ViaSat LinkStar Satellite Internet
LinkStarT is the highest
performance, star-based VSAT system for service providers, ISPs, and
corporate network managers who are seeking a system based on DVB
standards. LinkStar's edge is in its dynamic bandwidth allocation
that makes it more efficient and faster than other TDMA systems.
Terminals can transmit data to the network hub at speeds up to 1.15
Mbps, with data downloads of up to 60 Mbps, satisfying
bandwidth-intensive applications using IP data.
LinkStar offers several benefits:
- The highest return channel rate
on the market
- Rate-based operation that
increases your data throughput
- Guaranteed information rates for
each network location
- Lower-cost terminals because
fewer hardware components are needed and volumes increase as
markets expand
- DVB standards based for
compatibility worldwide
LinkStar can operate over C- or
Ku-band frequencies, and is scalable to small or large networks. A
Web-based NMS makes it simple to operate and easy to configure.

The DW4020 terminal is a
self-hosted, stand-alone unit that provides an integrated
broadband LAN solution to Windows, UNIX, Linux, MAC, and other
platforms running IP over Ethernet. The DW4020 is completely
self-contained, requiring no external PC to host any functions. It
performs many of the functions of a typical IP router, thereby
eliminating the need for a separate external router. Router
functions performed by the unit include IP routing using RIPV1,
RIPV2 or static IP addresses, DHCP Server (assignment of IP
addresses on the local LAN), Network Address Translation (NAT),
and Firewall using filters.
Key features include:
- Ethernet-based
- Operating System (OS)
independent
- Scalable
- Self-hosted
- Stand-alone terminal
The DW4020 terminal can achieve a
receive throughput of 2.0 Mbps or more over the satellite per TCP
session with an aggregate throughput of greater than 6.0 Mbps. In
addition, by implementing the Hughes Performance Enhancement Proxy
(PEP) feature, the number of TCP handshakes is reduced and the
user data is compressed. This feature minimizes latency over the
space link and accelerates the throughput performance so that data
can be delivered quickly to the user.
The DW4020 terminal provides
broadband access to multiple users connected to the same satellite
terminal and supports two-way connectivity between the remote
units and the World Wide Web. Adding new remote units is a simple
task with this scalable solution. As a business grows, terminals
can be quickly installed at new locations.
With DIRECWAY, corporate
intranets can be extended to remote locations without raising
concerns about security. The DIRECWAY network incorporates
multiple security mechanisms, conditional access and encryption to
ensure the privacy of all your information.
