    摘要： A method and system for determining a position of a rail-bound vehicle on a railway is disclosed. The apparatus comprises: a transmitter and receiver for wireless communication with at least one base station arranged at a predetermined position in the vicinity of the railway; a measurement device to determine a distance to the at least one base station based on measurements of the radio signals of the wireless communication in the phase domain; and a controller arranged to determine a present position of the vehicle on the railway based on the distance. A control system/method for controlling rail-bound vehicles in a railway system, and/or an internal or external system related to such rail-bound vehicles, using such position determination is also disclosed.

    摘要： Wireless communication systems for a vehicle, such as a train, are disclosed. In an embodiment, the wireless communication system includes a communication unit, an antenna, a power cable, a data transferring path, and a protective shield. The communication unit is arranged inside the vehicle. The antenna is provided on or above an exterior metal surface, such as the roof, of the vehicle. The power cable and the data transferring path connect the antenna and the communication unit. The protective shield is made of a conductive material, and is electrically and mechanically bonded to the exterior metal surface of the vehicle. The protective shield includes a cavity for accommodating the antenna, and at least one waveguide aperture extends through the protective shield and into the cavity.

    摘要： A method for identifying a source of error in a communication network including at least one client configured to be connected to a base station is disclosed. The at least one client is arranged on a vehicle repetitively moving in a predetermined area. The method includes the steps of: collecting signal quality data from the at least one client for an extended time period when moving in the area, the signal quality data including a plurality of data entries; determining a position in the area at which each of the data entries was collected and a time at which each of the data entries was collected; identifying an anomaly in the signal quality data, by comparing newly collected signal quality data with previously collected data. A source of error may be determined from the time and position when the signal quality data having an anomaly was collected.

    摘要： A vehicle communication system is disclosed, for use on e.g. trains, ferries and busses. The system includes an internal local area network (LAN) arranged within the vehicle; at least one antenna for wireless communication with external wide area networks (WAN) outside the vehicle; and a data communication router for providing data communication between said internal LAN and said external WANs. The data communication router includes a plurality of modems for communication with said external WANs, a subscriber identity module (SIM) pool including a plurality of SIMs, and a controller capable of periodically assigning SIMs within said SIM pool to any one of said modems. Hereby, a very efficient use of the modems and SIMs is obtained, leading to a less costly system and a more efficient communication.

    摘要： A method and system for a wireless communication system for a moving vehicle having a plurality of carriages is disclosed. The system comprises at least one internal network onboard said vehicle and at least one router, connected to the internal network and to at least one exterior mobile network, wherein the internal network comprises a plurality of network switches, connected together by cables, wherein the network switches are Power over Ethernet (PoE) switches. In at least one of the network switches it is determined if an input power received from a power supply is below a minimum power level. In case it has been determined that the input power level is below the minimum power level, power is received as Power over Ethernet from at least one of the other network switches, and the switch continues at least part of the network switch operation also when powered by the at least one other network switch.

    摘要： A system and method for providing wireless data communication between a wireless communication system in an aircraft and a stationary communication server outside the aircraft are disclosed. The wireless communication system includes a plurality of antennas, and a router in the aircraft configured to transmit and receive wireless data communication to and from a stationary communication server outside the aircraft through at least one ground base station via at least one of the plurality of antennas. The plurality of antennas includes at least one omnidirectional antenna and at least one directional antenna. The router includes a control unit configured to restrict the wireless data communication to solely occur through the at least one directional antenna the when the current altitude of the aircraft is determined to be above a predefined altitude threshold value.
