HughesNet delivers high speed Internet over satellite (not over your telephone line) so you can surf and talk at the same time. A phone line is not even required to have HughesNet! A certified installer will connect your computer to a satellite modem and link it to a satellite dish that's typically mounted on the roof of your home. The satellite dish sends and receives information (i.e., email, Web pages, files) over the Internet and delivers it your computer as super fast speeds.
