A data transmission system contains a transmitting and/or receiving unit on a track side and a transmitting and/or receiving unit on a vehicle side. Accordingly, the transmitting and/or receiving unit on the vehicle side contains at least one transmitting and/or receiving element on the vehicle side which is mounted in the region of a track vehicle door. The unit is covered by the track vehicle door and separated from the rail track when the track vehicle door is closed and remains uncovered by the same when the track vehicle door is open.

Data transmission system

A radio communication system has a base station and one or more antennas, each of the one or more antennas connects with a radio frequency port of the base station through an RF connection. Direct current and/or low frequency (DC/LF) signals are transmitted to an antenna via the RF connection corresponding to the antenna. The radio communication system further has an identification module at the antenna side, adapted to give an indication for identification of the antenna when receiving the DC/LF signals from the RF connection. Accordingly, the information exchange between the base station and a more or less intelligent 'identification unit' in the antenna is performed to allow identification of the antenna from the base station side and further allow diagnosis of the cable link.
