Synchronous FM

DIGIDIA has the complete solution for the transmission of FM programs through a network of FM transmitters using the same channel for a dedicated coverage area. The proposed system allows to synchronize all the FM transmitters within the same SFN (Single Frequency Network) cell, in order to avoid interferences when switching from one area (covered by one transmitter) to another one, like along the motorways for instance.
