Satellite internet is wireless internet beamed down from satellites orbiting the Earth. It’s a lot different from land-based internet services like cable or DSL, which transmit data through wires. Since it’s the only internet service that’s available nationwide, satellite internet is often the only way to get online for many rural homes and businesses, although it does still come with a few disadvantages (more on that later).
HughesNet and Viasat are the two primary residential satellite internet providers in the US. In the near future, Starlink (from SpaceX) and Project Kuiper (from Amazon) will also offer satellite internet service.
