1. A method for wireless data transmission, the method including the steps of:
(a) configuring a first terrestrial transmitter to transmit first terrestrial signals at a satellite signal frequency along
a first wireless transmission path to a user location, the satellite signal frequency comprising a frequency allocated for
direct satellite signal transmissions from a satellite along a satellite signal path to the user location for reception within
a satellite signal receiving window at the user location; and
(b) configuring the first terrestrial transmitter to transmit at a terrestrial transmission power level to produce useable
terrestrial signals at the user location, the useable terrestrial signals resulting in terrestrial input signals at a satellite
receiving antenna at the user location that are below an interference level with respect to satellite input signals resulting
from the satellite signals received at the satellite receiving antenna within the satellite signal receiving window at the
user location.
