The intelligent data transmission radio system IFD 3230 can be used for point-to-point or
point-to-multipoint communication applications.
The IFD 3230 consists of a base station and up to 15 mobile units. The data sent from the base station is received by all the mobile units, each automatically verifying the data and processing if applicable.
This wireless data transmission system has been used successfully in marshalling yards, where the pushing and shunting of locomotives is not automated, but is manually done by the locomotive operator who receives from the signal box the desired speed, which is displayed on his mobile unit.
