Satellite internet works similarly to satellite TV. It begins with an internet service provider sending satellites up into space to orbit around the earth. That ISP then relies on a signal routed through one of those satellites in low- or high-Earth orbit and a receiver dish that picks up that signal. The receiver is typically placed on your home or business in a spot with as unobstructed access to the sky as possible. You’ll connect a modem to that dish to translate the incoming signal into a workable internet connection.
