Speaker 1: with today's question, how does satellite internet operate? Let's imagine
Speaker 1: that you live way out in the middle of nowhere,
Speaker 1: or you're working at a site that's completely disconnected from
Speaker 1: the rest of the world, say in the middle of
Speaker 1: a giant national park, or a desert or a massive
Speaker 1: forest or something like that. How do you access the
Speaker 1: Internet in a situation like this? There are no cell
Speaker 1: phone towers for hundreds of miles. There's no DSL lines
Speaker 1: or cable access running along the street. Really, your only
Speaker 1: option is to look up in the sky and reach
Speaker 1: for a satellite. In fact, satellite internet access is really
Speaker 1: your only option. It's ideal for rural internet users who
Speaker 1: want broadband access, people camping in national forests, and anyone
Speaker 1: who's working in a jungle or a desert that's far
Speaker 1: from normal Internet access points. Satellite internet does not use
Speaker 1: telephone lines or cable systems, but instead uses a satellite
Speaker 1: dish for two way upload and download data communications. Upload
Speaker 1: speed is about one tenth of the five kill a
Speaker 1: bit per second download speed. Cable and DSL have speeds
Speaker 1: that could be ten times or more higher than that,
Speaker 1: but if you've got nothing, five kill a bits per
Speaker 1: second looks pretty good. There are several companies today offering
Speaker 1: satellite Internet access and you Usually the equipment consists of
Speaker 1: first a satellite dish approximately two ft by three ft second,
Speaker 1: two modems, one for up link and one for down link,
Speaker 1: and then some coaxial cables between the dishes and the modem,
Speaker 1: and a cable that connects to your computer. The key
Speaker 1: installation planning requirement is a clear view to the south
Speaker 1: that means no trees getting in the way, since the
Speaker 1: orbiting satellites are usually tending to be over the equator area,
Speaker 1: and like satellite TV, trees and heavy rains can affect
Speaker 1: reception of the Internet signals. Two way satellite internet usually
Speaker 1: uses Internet Protocol multicasting technology, which means up to five
Speaker 1: thousand channels of communication can simultaneously be served by a
Speaker 1: single satellite. I P multicasting sends data from one point
Speaker 1: the satellite to many points at the same time. By
Speaker 1: sending data in compressed format, compression reduces the size of
Speaker 1: the data and the bandwidth, allowing so many people to
Speaker 1: share that same connection. In some rural areas, there's also
Speaker 1: hybrid systems where the data comes down via satellite, but
Speaker 1: the up link is served with a normal dial up modem.
Speaker 1: This sometimes can reduce the cost and improve response times
Speaker 1: for the connection. So if you're in a rural area
Speaker 1: or a truly remote area and you want broadband access
Speaker 1: to the Internet, satellite Internet maybe a good option. In fact,
Speaker 1: it may be your only option for more on this
