Abstract: 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.

Abstract: 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.

Abstract: An active antenna device, a network device, an access point equipped with the network device and a plurality of distributed active antenna devices form components of a communication system. The active antenna device contains an antenna unit, an amplifier unit and a control unit, wherein the amplification of the amplifier unit is controlled by the control unit according to an instruction from a management unit located in the network device. The devices achieve a low handover frequency whereas rendering the communication less vulnerable to contentions and/or interference than in the conventional systems.

Abstract: A route monitoring system for a vehicle includes at least one camera, disposed at the route end, for recording video data relating indirectly or directly to a route section on which the vehicle travels, at least one display device for displaying the recorded video data, and a control device which indirectly or directly communicates with the at least one camera and the at least one display device. The control device is configured to display the video data recorded by the camera on the display device. The control device communicates with a vehicle control and/or operations command/control system for operating the vehicle and receives data from the vehicle control and operations command/control system, which data allow the respective vehicle location to be determined. The video data device is configured such that it displays the video data of the at least one camera on the display device depending on the respective vehicle location.

Abstract: A railway vehicle-side communication device for a railway vehicle for communicating with a trackside communication device. The trackside communication device has at least two communication modes, namely, a first communication mode having a first data transfer rate and a second communication mode having a second data transfer rate that is higher than the first data transfer rate. The railway vehicle-side communication device has a switch-over element setting the second communication mode in or in the vicinity of a station for communicating with a station-side communication device and setting the first communication mode outside of a station for communicating with a track-side communication device.
