ABSTRACT:
A system and method of transmitting and receiving RF service signals between a base transceiver station (BTS) of a wireless communication system and subscriber units within a structure. In the forward link, the system demodulates the RF service signal from a BTS to recover a digital service signal; conditions the digital service signal for transmission via the powerline of a structure; and modulates an RF carrier with the digital service signal to generate the RF service signal for wireless transmission to subscriber units within the structure. In the reverse link, the system demodulates the RF service signal from subscriber unit(s) to generate a digital service signal; conditions the digital service signal for transmission via the powerline; and modulates an RF carrier with the digital service signal to generate the RF service signal for transmission to the BTS. Another embodiment eliminates the modulation of an RF carrier with the digital service signal to generate an RF service and vice-versa at the BTS.
