Abstract: A method performs synchronization in an at least partly self-organizing radio communication system with a number of mobile stations which lie across an air interface within two-way radio range. At least some mobile stations from the number of mobile stations transmit synchronization sequences, by which a part or all the mobile stations of the number of mobile stations synchronize.

Abstract: The subject matter of the invention is a process and a system for wireless transmission of infotainment components between an in-vehicle network in a vehicle and a network external to the vehicle, the in-vehicle network having a reception readiness state and an idle state and by way of a remote control of the vehicle can be shifted from the idle state to the reception readiness state. Furthermore the invention relates to a remote control for transmission of a prompt signal, the in-vehicle network by actuating an actuating element of the remote control shifting the in-vehicle network into the reception readiness state, by which infotainment components can be received from a network external to the vehicle.

Abstract: A method and arrangement for controlling a system of multiple traffic signals for regulating the traffic of vehicles is described. Traffic data is transmitted by wireless transmission to traffic data processing units assigned individually to a locally limited group of traffic signals, and each traffic data processing unit performs an analysis of the local traffic situation for the environment of the locally limited group of traffic signals up to, at the maximum, the neighboring locally limited groups of traffic signals.
