Hi, I'm Robin Higgins and this is what is C-band. Okay, so the C-band is a portion of the electromagnetic spectrum and it ranges from 4 gigahertz to 8 gigahertz. Okay, so what does that use? What does that mean, what is that used for? Well, basically, this is the chunk of the electromagnetic spectrum though a bunch of different satellites are on. So these satellites have a bunch of different functions that make all of our lives much easier including some WiFi, cordless phones and weather radar systems. This will also include some cable TV. And so it's main competitor or alternative is the KU-band and that spans from 11.2 gigahertz to 14.5 gigahertz and the KU-band basically is just different satellites. Because if you have too many satellites trying to get on the same frequency, you're not going to be able to get the signals, you're not going to be able to pick it up, there's going to be too much noise. So you have to assign the different frequencies that everyone is going to use to make sure the signal comes in clearly and so these bands are pretty equivalent. Sometimes people say the KU-band is more sensitive to bad weather which of course is anything that can really effect how a satellite would be able to communicate with Earth so that includes you know heavy clouds or raining or snow or anything that's basically going to block that signal from space to get back down t use to bring us our delicious delicious television. Alright, I'm Robin Higgins and this is what is the C-band.
