Abstract

System radiomóvil isofrecuencial extraction / insertion and station for radio, said system comprising a plurality of fixed relay stations distributed on an area assigned and intertwining, each comprising media station transceiver, multiplex and organs of control, receiving said relay stations radio frequency signals coming from a plurality of users, mobile within this area assigned to simultaneous redifundirlas e isofrecuencial mode. The connection between the stations are connected using a back connection in closed ring, in particular by type system insertion / extraction digital 2 mbit / s.
