Abstract
A system for the distribution of radio-frequency signals includes a main unit associated with at least a first radio communication set, at least a remote unit associated with at least a second radio communication set installed in a preset area, for the radio coverage of the area, and a communication channel associated with the main unit and with the remote unit, wherein the main unit (2) and the remote unit have analogue modulation elements of the signals to be sent on the communication channel. The remote unit includes at least a selective amplification unit associated with the second radio communication set and having analogue/digital conversion elements of the signals coming from the main unit, through the communication channel, and/or of the signals coming from the second radio communication set, digital filtering elements of the digital signals coming out of the analogue/digital conversion elements and amplification elements of the signals coming from the main unit, through the communication channel, and/or of the signals coming from the second radio communication set.
