Is Satellite Internet Service a Good Option?

By Bob Rankin

If you live in a rural area, your Internet access options may be limited. DSL and cable internet service are not available in many thinly-populated areas. Forget about 4G and even 3G cellular access. For many rural residents, Internet access boils down to a choice between miserably slow dial-up and satellite Internet access. Read on learn about the pros and cons of satellite internet service…

How Does Satellite Internet Service Work?

Satellite Internet is a wireless communications technology. At the user’s end, a satellite modem is connected to a dish antenna. Signals are transmitted between the user’s dish and a satellite relay station up in the sky. The satellite relays data to the ISP (Internet Service Provider) dish back on the ground; from the ISP’s hub, Internet traffic is carried via traditional terrestrial cables. There are pros and cons to satellite Internet.

On the plus side, satellite Internet can reach remote areas where no other type of Internet access can go. Satellite Internet is moderately fast; consumer data plans range up to 15 Mbps. (For comparison, see my related article What is The Fastest Internet Connection?) But there are limitations on the quality of satellite Internet.

The biggest is latency – the delay between sending a data packet and getting a reply. Latency can be a problem for interactive applications such as VoIP (internet calling), video chat, and online gaming. Streaming video may stutter due to buffering delays. Latency is higher in satellite Internet systems because the data signal must travel tens of thousands of miles to the satellite, down to the ground, and then back the same route again.

The geostationary communication satellites that are used for satellite Internet service are about 22,230 miles above the Earth. So your actual data path is four times that, or over 89,000 miles. So even at the speed of light (186,000 miles per second) that round-trip transmission takes almost half a second (500 ms). That’s a noticeable span when doing anything in “real time” such as playing a game, or having a voice conversation. This half-second satellite latency is imposed by the speed of light, but additional network latency can add to the problem of slow or stuttering performance.

  1. These latency times are crazy! Send the signal through subspace or with quantum entanglement so that they are near instantaneous!

  2. Basically, the satellite is a good alternative for rural homes or businesses since they have the slowest internet services due to wired services have a hard time to reach them. That’s where the part of satellite services becomes perfect since this internet service doesn’t need cords. It would use a dish to transmit the data to its internet providers which is perfect for rural areas as we’ve mentioned earlier. I’ll refer this to my youngest brother since he’s living in the old country home with our parents. This should help me get better and more regular updates from them. Thanks!

  3. A friend got WildBlue and is extremely happy. All he had before was AOL dialup with a flaky phone line. He has no complaints.
