Patent ID: 8694034

Claim:
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.
