Abstract
A signal conditioner (SC) and method for communicating via a shared transport medium (STM) between a BTS and remote antenna entity (RAE). A first SC connects to the BTS and a second SC connects to the RAE. Each SC connects to a cable modem or BPL modem that interfaces to the STM. The first SC receives an RF signal carrying an analog baseband signal (ABS) representing digital signals for multiple communication channels. The first SC generates a CDS based on power level measurements of the ABS, and then transmits the CDS to the second SC via the STM. The second SC recovers the CDS, converts the CDS to another ABS, generates an RF signal carrying the other ABS, and transmits this RF signal to the RAE for transmission away from the RAE. The first SC and second SC also facilitate communication of a CDS from the RAE to BTS.
