How does IP work over satellite?
speaking, Internet traffic transmitted over satellite works no differently than
transmitting it over terrestrial lines. The best way to think about it is to view
satellites as a digital highway in the sky. While there have been some questions raised
about the theoretical limits on speeds at which Internet traffic may be transmitted over
satellites, practical experience by NSIS-VSAT Services and the major Internet carriers
confirms that speeds which are required by ISP's can be carried over satellites without
any appreciable slowing of response times or any decrease in the data rates.
be concerned with security issues?
Carrying IP traffic over satellites poses
the same degree of security risks as sending it over a terrestrial connection. If security
is a concern, then you can use encryption, a process of electronically altering a signal
from its original condition to prevent unauthorized use. There is no encryption on the
satellite links but there are a variety of companies which can provide encryption software
for the traffic. This is a common practice for banking and credit card and sales
transactions over the Web.
|Why do I
care where my traffic lands?
The network of interconnected computers which
form the Internet is comprised of thousands of smaller networks or access roads. However,
the backbone or major 'roads' are maintained by four major providers, all of whom are
committed to routing IP traffic as quickly as possible. Your data packets will get to
their destination eventually no matter where they land. However, they will get there
faster with fewer lost packets and delays if they are routed directly onto the backbone.
speeds do satellites offer?
All services include simplex or duplex, balanced
or asymmetric links from 64kbps to 45 Mbps. Higher rate services are also possible in
selected coverage areas.
|How do I
determine the right speed for my service?
The data rates which are available
over satellite are the same as you find for terrestrial links. If you currently use a 128
kbps link, then the same link can be established over the satellite. One of the key
advantages of the NSIS-VSAT Services service is the ability to easily increase the data
rate of the service (in 64 kbps increments) as required to keep up with the end-user
|How does a
satellite connection compare to terrestrial links?
Satellites are ideal for
areas hampered by inhospitable geography or where the terrestrial infrastructure is poor.
In many parts of the world, they can provide the only truly reliable means of access to
the Internet. Even in developed parts of the world, satellites are often an attractive
alternative because they are distance insensitive. In other words, your costs do not
change depending on where you are located or your proximity to the U.S. backbone.

What equipment do I need?
In addition to
your server or LAN dial up equipment, you will need a router, a modem and a transceiver, a
combination 'transmitter' and receiver. In addition, you will need a satellite antenna or
dish, basically a parabolic antenna which collects and focuses satellite signals.
sell, install and service the satellite equipment?
Yes, we do sell and
install equipment. We can also provide a list of suppliers and equipment integrators
and we insist on all equipment meeting our performance specifications.
recommend specific vendors?
Depending on your requirements, we are happy to
recommend vendors with whom we have worked and who meet our performance standards. Some of
the vendors have in-country representatives or recommended integrators, who can help
specify and install your system.

Do you provide traditional IP services along with space
segment and teleport services?
Through our partners, we can help with
obtaining domain name service and IP addresses. We can also point you in the right
direction for web page hosting and design, security products and consulting services.
I go for customer service and access problems?
Where you go for help depends
on the nature of the problem. Lines of demarcation will be clearly spelled out in your
contract, and start-up and operating procedures will be furnished.
In general, the backbone service provider continuously monitors the links to the ISP's
and corporate users, and can determine if there are any problems in passing IP traffic to
or from the remote location. NSIS-VSAT Services employs a team of engineers who are
responsible for monitoring the satellite and teleport systems, including satellite
performance, teleport equipment performance and terrestrial interconnects. Both NSIS-VSAT
Services and the backbone provider maintain continuously staffed control centers which can
quickly isolate problems to the user end, the network, or the satellite link and teleport.

|Licensing & Regulatory
What about licensing issues?
responsible for obtaining any necessary licenses and complying with any relevant local
regulations. We can provide general information on the licensing requirements for the use
of satellites in particular countries, or can help direct you to the appropriate local
authority for further information.
