Abix has delivered the first phase of the Tetra voice and data communication system to ALL – América Latina Logística, which now has communications from the CCO located in Curitiba and the trains between Campinas and Embu-guaçu. The licensing (authorization to run) of trains will preferably be done through the Tetra system. With this system, the average message delivery time, which used to be 90 seconds, is now approximately 5 seconds, bringing huge productivity gains to ALL.
