A Guide to Understanding High Speed Internet Access
Satellite Internet involves a complex set of technologies that can be explained using a simple triangle analogy.
Positioned at the triangles peak is the geostationary satellite which is located 22,000 miles above the Earth’s equator. On the bottom of the triangle, one of the points represents the satellite at the home or business and the other point represents the communication center of the satellite Internet provider. The lower points on the triangle receive and send information to the geostationary satellite and therefore high speed satellite Internet for customers becomes possible. The signals have so far to travel when sent or received which is incredible when you see how fast satellite Internet is.
Explore what satellite Internet providers can offer.
Understanding the customer’s 2-way satellite dish
Unlike the satellite dished of our past, modern dishes are not an eyesore. Most Internet satellite dishes are dark grey and only 28” x 26” (about the size of a small briefcase). Using a mount pole, a professional installer will mount the satellite dish on or near the home.
The two-way satellite dish must have a clear view of the southern sky and bust not have trees of buildings that are in the way of this view. Through cable, the dish is connected to a modem inside the home or building. In order to connect to satellite Internet, the user must connect the computer to the modem. The user gains high speed Internet access as the modem translates the data.
About the geostationary satellite
Internet service is provided to thousands of customers from the geosynchronous satellites that are placed by the satellite Internet companies to orbit around the Earth at 22,000 miles above the equator. The satellite orbits around Earth at the same speed the Earth rotates because of the high placement. As a result, the satellite never appears to be moving and is therefore “geosynchronous.” Through this type of orbit, we as satellite users have the ability to point our dish at one particular satellite and never have to change the angle. Because of this, satellite dishes are able to point to the same satellite and receive continuous signal.

About the satellite dish at the Internet provider’s communication center
The satellite Internet service provider has a satellite at their facility that sends and receives signals from the orbiting satellites. At this communication center, the provider is then able to give its customers high speed Internet access.
