Internet Connection Types - CompTIA A+ 220-1201 - 2.7

These days, you can be almost anywhere on Earth and have access to the internet. We're able to get that access thanks to satellite networking where we are communicating from Earth to a satellite and back down to Earth again. Since we are launching a satellite into space to provide this type of connectivity, the relative cost of

satellite networking is a bit more expensive than something that you might use terrestrially. But that additional cost does provide a very functional connection. It's very common to see 100 megabits down and five megabits up when you're using a satellite network connection. This is perfect for remote sites and places where it may not be

possible to get a traditional form of internet connectivity. One of the challenges we've traditionally had from satellite networking is that we have to send this signal so far into space and back down to Earth again that it adds additional latency to the connection. Traditionally, we've seen systems have about a quarter of a second up and a

quarter of a second down. So, there's about half a second latency just to be able to send packets up to the satellite and back down again. The newer Starlink connections are a little closer to Earth and therefore the latency numbers are a bit smaller. Starlink advertises around 25 to 60 milliseconds of latency, but

even they're working to bring those numbers even lower. Satellite networking isn't without its faults. Of course, we have the concern of being able to see the satellite. So, our connection between us and that satellite needs to be a line of sight. We might also have connectivity problems if a large storm comes through. We refer to that type of
