INSAT 3C to offer LinkStar satellite service over India, Nepal, Bangladesh and Bhutan
Derived from a press release from ViaSat: 18th Aug 2005
Viasat are supplying a LinkStar broadband network to HCL Comnet Ltd, a subsidiary of HCL Technologies, for shared hub network services in India.
HCL Comnet will be offering network services, from low-rate point-of-sale data to broadband virtual private networks and Internet access, to about 100 sites already with planned expansion to 500 sites in the next three years. LinkStar VSAT options for network access and bandwidth management make it an efficient choice for all types of applications.
The HCL Comnet shared hub services are targeted at banks, stock brokers,
and gaming applications that need fast access and low-rate transactional
data, as well as enterprise customers looking for high-speed, secure
client-server connections.
“The flexible bandwidth allocation and bandwidth-on-demand feature of the
LinkStar system will find use in emerging applications like interactive
distance education, backup for landline connectivity using VSAT, and
Internet services to remote locations,” said HCL Comnet vice president Mr.
S. Barathy.
The addition of the LinkStar satellite network by HCL Comnet adds to previous ViaSat installations of Skylinx and StarWire mesh networking systems, as well as a 9-meter ViaSat antenna at the hub in Voida UP.
INSAT 3C 15.4m solar array,
Two C band transmit antennas, each 2m dia. One C band receive antenna
0.7m dia.
ViaSat dynamic bandwidth allocation increases or decreases data rates
on-the-fly to adjust to each customer and use the available satellite
bandwidth in the most efficient way.
Nine MHz of transponder capacity on the INSAT 3C satellite will carry the
network traffic. Data rates will begin at 256 on the inbound and 4.4 Mbps on
the outbound (hub to remotes). The system can support up to 3.3 Mbps uploads
from remote sites and up to 45 Mbps downloads from the hub.
The advantages of the LinkStar VSAT system can be traced to its versatility.
The system is cost-effective for a full spectrum of applications, from low
speed, quick-turnaround retail transactions to broadband multimedia
applications. The LinkStar system can operate in a proprietary configuration
from ViaSat or according to the DVB-RCS international standard.
