1. A terrestrial radio frequency (RF) communication system, comprising:

  • a near-end station at a fixed terrestrial location within a first cell receiving a signal having at least one first carrier frequency within a cellular frequency band from a wireless cellular communication system, the near-end station including;

    a near-end converter converting the first carrier frequency to at least one first intermediate frequency;

    a near-end channel selectivity circuit selecting one channel from the signal and converting the first intermediate frequency to at least one second carrier frequency, wherein the second carrier frequency is a non-cellular frequency, and a near-end transmitter wirelessly transmitting the selected channel having the second carrier frequency, and wherein the near-end station does not change the modulation or signalling scheme of the signal having at least one first carrier frequency; and

    a far-end station at a fixed terrestrial location within a second cell located apart from the first cell including;

    a far-end receiver wirelessly receiving the selected channel having the second carrier frequency from the near-end transmitter and converting the second carrier frequency to a second intermediate frequency, a far-end channel selectivity circuit selectively filtering the received channel and converting the second intermediate frequency to the first carrier frequency, and a far-end transmitter transmitting the received channel having the first carrier frequency, and wherein the far-end station does not change the modulation or signalling scheme of the selected channel having the second carrier frequency.
