How Does Satellite Internet Work?

Just as the name suggests, satellite internet is gaining access to the internet through the use of satellite technology. There are three major components to satellite internet equipment: two modems, the satellite itself, and coaxial cables that run between the two.

According to NetworkReviews.Net the signal for your satellite internet begins at the hub belonging to the internet service provider. Then, the signal is sent into the sky by a very large satellite dish. The signal will then be relayed to your personal home satellite dish. The coaxial cables mentioned earlier will be connected to the satellite dish and they will carry the signal from the dish to your router. Finally, the signal will reach your computer- and you have internet.

Multitasking Technology of Internet Protocol (IP)

Typically, satellite internet service provider companies use what is called an internet protocol multitasking technology. Generally, dial-up internet service is unable to handle large amount of bandwidth at one time. However, satellite internet service providers, with the use of internet protocol multitasking technology, are able to serve approximately five thousand users on one satellite all at the same time. Also, the IP multitasking technology compresses information files in order to ensure that more data can be sent out at the same time.

Satellite Internet Service Requirements

There are only a few very simple requirements when it comes to satellite internet service. First, you need to have the equipment that was mentioned earlier: personal satellite dish, two modems, and coaxial cables to connect the two. Next, you must have a view of the southern sky that is free and clear of obstacles such as power lines, trees, etc. You will need to ensure that your personal satellite dish has a clear communication line between the satellite dish that is orbiting in space- this guarantees that you get the best connection possible for the relay of the signal to your equipment.

Pros and Cons to Satellite Internet Service

One of the pros of satellite internet service is that those who are constantly moving or live in an area where cable isn’t yet available can easily have satellite internet. Also, the connection speed of satellite internet service is around ten times faster than dial-up.

As with anything, there are some negatives when it comes to satellite internet service. First, though it is true that satellite internet has faster loading speeds than dial-up, it is still slower than cable internet. Also, there is more limitations in the amount of traffic that satellite internet can handle, as opposed to cable internet service. This means that during the peak internet traffic hours, you will have much slower internet speeds. Also, weather conditions, such as fog and clouds create a barrier between your home satellite dish and the one that is orbiting in space and can therefore affect your internet connection.

So, when trying to decide whether or not satellite internet service is for you, weigh the pros and cons. You must decide if you are going to be willing to put up with those negatives that come with satellite internet service. Of course, keep in mind if you live in an area where cable internet is not available, satellite internet is a much more desirable option than dial-up internet.
