Abstract

A terrestrial radio system for delivering to consumers data transmission services, Internet services, two-way capabilities and single-channel or multi-channel video programming, including national, regional and local television broadcast signals, as well as an apparatus and method thereof. The terrestrial radio system transmits terrestrial signals at satellite-allocated frequencies while mitigating interference with satellite signals to reuse satellite-allocated frequencies.

Claims
