Introduction
Satellite Internet services are used in locations where terrestrial Internet
access is not available (such as rural areas) and and in mobile areas (such as
vessels).
Satellite Internet connects the computer to the Internet service provider
through a satellite orbiting miles above the earth. It doesn't require telephone
lines. Computer user
received internet communications through a satellite dish.
Satellite connections come in two forms :
-
One-way satellite
You use both a dial-up and a satellite modem for this kind of connection. As
it name implies, only communicates with the Internet in
one direction i.e. you can download information from the Internet at high
speed via satellite, but you do not send it via the satellite. The return
channel for uploading data to the Internet in a one-way satellite broadband
installation is often by ISDN line or dial-up modem.
First, you connect to the Internet via your dial-up modem. When you click on a
link to view a different Internet page, the process really begins. While
normally your request would go directly to the web server, with Satellite
Internet it is actually sent to your provider's Network Operations Center (NOC) and the
NOC forwards the request to the web server.
The web server sends back the page to NOC which transmits it to the
satellite which bounces it back to be picked up by the satellite dish mounted
on your house. The data is then sent through the dish into the satellite
modem, which translates it for your computer. The entire process from
requesting the page to receiving the page takes no more than one-half of one
second.
The limitation : Because one-way satellite solutions operate in only one direction (i.e. the
satellite dish can receive data but not send it), you still need to maintain
your dial-up modem or ISDN connection to be able to request information from
the Internet. This means that if you have only one phone line, your phone-line
is tied up while you are accessing the Internet. Furthermore you still need to
pay for a dial-up or ISDN account with your Internet service provider.

two-way satellite
Two-way satellite broadband uses a satellite dish to both send and receive
data
With two-way service, the process is the same except you no longer use a
dial-up modem and instead have an always-on connection just as you would with
Cable Internet or DSL.
Why Satellite Internet Access?
Satellite internet access is a connection that outpaces all others for Internet
speed, it also affords you unparalleled convenience and flexibility with your
Internet service. This latest form of Internet
service can revolutionize how you work at home or at your office,
or even when you’re on the road for business or on vacation for pleasure.

With satellite internet access, you create one of the fastest internet
systems possible by establishing a link between a modem on your computer,
a dish outside your building like you would use for satellite television
or radio, and the distant satellite itself orbiting the planet thousands
of miles up in space. It’s a connection that promises the future in
Internet speed, accessibility, and convenience in the present. What’s
more, you can also add private information networks and phone services to
many of these satellite Web systems.
One of the most fascinating and attractive features of this form of
Internet is its convenience. Using a satellite to pick up your Internet
opens up a world of options for you. Your satellite dish can be attached
to any vehicle or structure you can imagine almost. Try your pickup truck,
your RV, or your trailer, not to mention your office, home, automobile, or
boat. The options are limitless, as are the uses for this type of Internet
service. Internet dishes could be used for everyday personal and business
use, as well as special occasions such as emergency events and one-time
promotions. When you think satellite dish, you imagine a tangle of wires
and impossible set up instructions. Not so with these dishes. You can have
them shipped in a matter of days and set up in a matter of minutes.
For big industrial strength jobs, satellite internet providers can set
up what they call their “big dish” systems, which provide the strongest
and most high-tech capabilities available. These can bring you abilities
up to 512Kbps uploads and 2Mbps downloads. Such a system could include
equipment like the VSAT Systems Satellite, a high-end service that can
provide what no other Internet hook up can provide.
Of course, shop around when you are about to make such a significant
decision for your professional and personal life. Satellite hook up is not
for the faint of heart and can represent a significant investment. But if
you need these capabilities, there is no better way to acquire them. Just
make sure to speak with a qualified Internet provider and their satellite
specialists to gauge your requirements. |
