Abstract
Systems and methods according to embodiment of the present invention prevent or otherwise mitigate data corruption and interference that may result when a communications on-the-move transmission is blocked by a radio relay link antenna transmitting on a shared frequency band. Harmful radiation that could affect persons blocking the line-of-sight of a COTM transmission is also prevented or mitigated. According to one embodiment of the present invention, if a building or other obstruction blocks the line-of-sight between a COTM antenna and a target satellite, the transmission will automatically cease, preventing or minimizing any potential interference that can occur, such as the interference to a radio relay link antenna operating atop a building. Similarly, persons who may have been in the line-of-sight will not be subjected to harmful radiation. COTM transmission remains offline until free line-of-sight is re-established.
