Abstract
Sistema radiomobile isofrequenziale comprendente una pluralità di stazioni ripetitrici fisse (S1, S2,_Sn) distribuite su un'area assegnata e collegate fra loro, ciascuna stazione comprendendo mezzi a ricetrasmettitore (R/T), multiplex (MUX), ed organi di comando (G). Le stazioni ripetitrici (S1, S2,_Sn) ricevono i segnali a radiofrequenza provenienti da una pluralità di utenti, mobili entro la detta area assegnata, per ridiffonderli in modo simultaneo ed isofrequenziale.Il collegamento tra le stazioni è realizzato mediante una dorsale di collegamento (D) chiusa ad anello, ed in particolare mediante un sistema di tipo drop/insert (DI) digitale a 2 Mbit/s (figura 1).
