I am getting huges net and I have a few questions.?

Someone in my family has got a psp. Could they go on the internet with the hughes net with that. Do we need a router or how does it work. Also someone has got iphone and labtop. Can they go on with that also? Also I heard something bout bandwith I have no idea what that means. If you could explain that be good. When I mean go on the internet I mean by wifi. Any other helpful information would be great. Thanks.
