How Does Satellite Internet Work?

For people who live a good distance from a phone company or cable provider, there is still hope if you wanted to get a broadband internet access just like everyone else. Thanks to satellite internet, it is now possible to get high speed internet access even if you live in a more remote area. Mobile satellite internet is also very useful for people on-the-go who want to access the net. How is it possible? And what is the difference between satellite and other types of high speed internet access?

Satellite internet is more expensive and it's not that easy to install. Usually, your provider's technician will take care of installing the device. There are three kinds of satellite internet access.

  • One-way multicast – is more similar to a one-way terrestrial return. This kind of satellite internet access includes interfaces to a public switched telephone network. An internet connection is not required, but many applications include a File Transfer Protocol (FTP) server for data broadcast.
  • One-way with terrestrial return – These are satellite internet systems that employ traditional dial-up access to the internet, with outgoing data traveling through a regular telephone modem, but with downloads happening via satellite at a speed comparable to other broadband internet access.

  • Two-way satellite access – This type of connection sends user-requested data (like a web address) from an orbiting satellite to a hub, and then to the Internet. The satellite dish must be perfectly positioned to prevent interference with other satellites. Also, power management needs to be used to adjust the amount of transmission power to compensate for conditions like the changes in climate.

Satellite Internet is generally popular in areas that other choices like cable or DSL internet are not available, such as rural areas. Check availability of various internet providers to see what your technology options are.
