Abstract: A satellite ready building comprises a plurality of studs and satellite wires positioned adjacent to the studs having a first termination and a second termination. A connector is coupled to the second termination of the wires. The first termination is coupled through the roof or the siding of the building. Drywall is installed in the house after the wires are installed. The first termination may be installed in a radome positioned on the roof of the building.

Abstract: A method and apparatus for mitigating communications interference between satellite communications systems in different orbits is disclosed. The method comprises the steps of evaluating a geometrical relationship between a second ground station and the satellites in the second satellite constellation, and directing communications between the second ground station and the second satellite according to the evaluated geometrical relationship. In one embodiment communications are handed over from a first satellite to another satellite when the first satellite is no longer at the highest elevation angle of visible satellites. In another embodiment, handover occurs when the first satellite drops below a minimum elevation angle.
