SuperLink is a VSAT based service
that uses communications satellites for establishing point to
multipoint connectivity forming a network in a Star Topology.
The central site or the Hub forms the focal point of the network.
SuperLink system is based on
the Hughes Network Systems (HNS) Integrated Satellite Business
Network (ISBN) and uses Time Division Multiplexing (TMD) to
communicate with multiple remote sites in the network. A high
speed TDM carrier is broadcast from the Hub site and is received
by each remote in the network. The information that is meant
for a particular remote is identified by a unique header. The
remotes communicate with the Hub using burst carriers. The basic
access mechanism for the remote to Hub communication is Time
Division Multiple Access (TDMA). There is a significant difference
in the size of the Hub and the remote antennas. The expensive
satellite bandwidth is effectively shared by a number of sites
thereby driving down the operating cost of the network. The
connection between the remote and the Hub is not always “ON”.
The Burst is transmitted on pre-determined frequencies whenever
there is a requirement.
SuperLink is ideal for establishing
LAN/WAN connectivity to support various mission critical applications
at a fraction of a cost for a point to point always-on SCPC
link. Some of the applications that are being successfully delivered
via SuperLink include point
of sales, inventory control, enterprise networking, basic Internet
access, SCADA, video conferencing, video broadcast etc.
SuperLink is being offered
by Supernet since 2000 thereby enabling its customers to reach
far flung hard to reach locations in a cost effective manner.
The communications satellite, located at 35,000 km above the
surface of the earth, acts as a repeater and bounces the high-frequency
microwave signals between the hub and the remote and vice-versa.
