1. System (1) for the distribution of radio-frequency signals, comprising:

  • at least a main unit (2);

    at least a remote unit (3);

    at least a communication channel (4) associated with said main unit (2) and with said remote unit (3);

    wherein said main unit (2) is associated with a plurality of first radio communication sets (A), wherein each first radio communication set (A) produces a respective radio-frequency signal relating to a specific frequency band and to a specific operator, said remote unit (3) is associated with a plurality of second radio communication sets (B) installed in a preset area, for the radio coverage of said area, said main unit (2) and said remote unit (3) have analogue modulation means (9, 10) of the signals to be sent on said communication channel (4), and said remote unit (3) comprises a plurality of selective amplification units (20), each of which dedicated to a specific frequency band and to a specific operator, associated with a respective second radio communication set (B) and having;

    analogue/digital conversion means (21, 22) of the signals coming from said main unit (2), through said communication channel (4), and/or of the signals coming from said second radio communication set (B);

    digital filtering means (23, 24) of the digital signals coming out of said analogue/digital conversion means (21, 22);

    amplification means (27, 28) of the signals coming from said main unit (2), through said communication channel (4), and/or of the signals coming from said second radio communication set (B);

    digital/analogue conversion means (25, 26) of the filtered digital signals.
