Hughes Net is what they offer via satellite, they claim it is high speed, here are some specs pulled from their website.
"HughesNet speeds are based on download speeds of up to 2.0 Mbps for HughesNet Power 200 service, 1.5 Mbps for HughesNet Power 150 service, and 1.0 Mbps for HughesNet Basic service. Actual speeds vary based on the amount of traffic on the Internet, content on a particular Website, or by the overall performance and configuration of your computer. Stated speeds not guaranteed."
I did have HughesNet about 5 years ago and let me tell you that it was a mistake, even though the actual price has come down its no faster then DSL and at times no faster then dial up. I know that Direct will let you bundle AT&T dsl with your satellite but it really only saves you $10 or $12 which is what you will spend if you keep cable internet with no tv package. So I would suggest sticking with cable high speed if its available.
