    摘要: A method for wireless communication between a moving vehicle and remote servers through at least one external mobile network. A router in the moving vehicle is configured for receiving and transmitting wireless data to and from both an aggregation server, using aggregated communication over at least two separate links, and at least one other stationary communication server, using non-aggregated communication over a single link. The router is further accessible by a plurality of client devices onboard the moving vehicle. At least one selection rule is provided in the router for selecting whether to use aggregated or non-aggregated communication, and a determination is made, upon a request from a client device to communicate with one of said remote servers, whether one of the at least one rules applies; and if so selecting to use aggregated communication via the at least one other communication server for communication based on the determination.

    摘要: A wireless communication system for an evacuated tube transportation system, wherein the evacuated transportation system comprises a tube or tunnel which is at least partly evacuated to provide a low-pressure within the tube/tunnel, and a guiding structure to guide a moving capsule along the tube/tunnel. The wireless communication system comprises a plurality of base stations arranged on the inside of the tube/tunnel, distributed along the length of the tube/tunnel, and connected together in a backbone communication path, the communication path further being connected to an exterior network, enabling communication with at least one stationary communication server outside the tube/tunnel, and wherein the moving capsule comprises a router for communication with said base stations.

    摘要: A method and device for wireless communication between a mobile router in a moving vehicle, such as a train, and an external wireless network is disclosed. The external network includes a plurality of base stations distributed along a vehicle path of travel in compliance with a WLAN standard. The method includes: setting a current value for a timeout parameter within the WLAN standard to a default maximum value exceeding a maximum propagation time between neighboring base stations along the vehicle path; determining when at least one mobile router is within the range of a first base station; determining a roundtrip time for communication between the first base station and the mobile router of the mobile router being most distant from the first base station; setting, in case this roundtrip time is significantly lower than the current value, a new current value in dependence on the roundtrip time.

    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 router network connected to a plurality of antennas, wherein the router network is configured to transmit and receive wireless data communication to and from a stationary communication server outside said aircraft through at least one ground base station via said antennas. The router network includes a plurality of connectivity nodes being physically separated and distributed within the aircraft, the connectivity nodes being connected to each other via a bus, and each connectivity node including a control unit, at least one modem, and preferably a plurality of modems, and a connection to at least one of the antennas. Further, each antenna is connected only to one of the connectivity nodes.
