Satellite broadband offers two-way Internet access via satellites. Your computer, through a special satellite modem, broadcasts requests to a satellite dish that sits on top of your home or business. The dish then sends and receives signals from satellites that orbit some 22,000 miles above the equator. As long as your dish maintains a clear view of the southern sky (in the U.S.), you receive broadband Internet access.* Currently, satellite broadband is slower in both the uplink and downlink, when compared to a DSL Internet service, for example.
