You are correct-a-mundo Lude. Here's from Sprints site:
"Sprint's fixed wireless technology uses a stationary 13.5" x 13.5" diamond-shaped device called a transceiver that is mounted on the outside of your home, usually on the roof.
The transceiver is pointed toward a radio transmission tower that sends and receives signals. Once the signal is received by your transceiver, it is sent to the modem and computer in your house."
Earth based.
But..... I got my T1 here with speed to fuckin' burn, so I too, am happier than a pig shit.
