AbstractA system and method for distribution of RF communication signals. First RF communication signals are downconverted in a first signal processing subsystem and transmitted to a second signal processing subsystem via twisted-pair cable. The downconverted first RF communication signals are upconverted at the second signal processing subsystem to provide recovered first RF communication signals, and the recovered first RF communication signals are transmitted via an antenna. Operating power for the second signal processing subsystem is provided from the signal processing subsystem, and the second signal processing subsystem determines the occurrence of an event and transmits autonomous information signals thereabout to the first signal processing subsystem.
