Abstract: The system includes a computer server receiving data representative of the temperature of the cabin and including a database containing, for the aircraft, a predetermined cycle of regulation of the temperature of the air of the cabin; a ground pre-conditioned air unit including: a pre-conditioned air generator and a control module; and a user interface connected to the computer server and transmitting a control signal to the control module; and the control module, upon receiving the control signal, controlling the pre-conditioned air generator, according to the predetermined cycle, which is modulated depending on the data. This system makes it possible to control the temperature of the cabin in real time, so as to correctly disinfect it.

Abstract: A control unit and a method for controlling a wireless data transmission between a wireless terminal and access points of a communications network in a transportation device, as well as a computer program for executing the method. The wireless terminal is assigned to two or more of the access points in such a way that one communications channel is available between the wireless terminal and the access points for wireless data transmission between the wireless terminal and the access points. A control unit is used, in the case of transmission from the access points towards the wireless terminal, to select at least one of the access points for wireless transmission to the terminal and/or in the case of transmission from the terminal towards the access points, to determine a message for further use in the communications network based on the messages received from the terminal by the access points.

Abstract: In a method for generating a digital key in a first communication device and in a second communication device, the first communication device transmits a first electromagnetic signal to the second communication device, which extracts the digital key from the received first electromagnetic signal. The second communication device transmits a second electromagnetic signal to the first communication device, which likewise extracts the digital key from the received second electromagnetic signal. A direct signal component, transmitted on a direct signal path between the first communication device and the second communication device, of the first electromagnetic signal and of the second electromagnetic signal is attenuated.

Abstract: Configurations of security settings of an access point arranged on board an aircraft. An exemplary embodiment of a method for configuring security settings of an access point arranged on board an aircraft for the authentication of mobile terminals comprises: receipt of flight-related security data from a mobile terminal via a configuration interface of the access point; and configuring of security settings of the access point in a configuration mode based on the flight-related security data so that automatic authentication of preconfigured mobile terminals for access to the access point is possible.

Abstract: A method for mutual monitoring of mobile network nodes of a network, wherein each network node continuously monitors the presence of neighboring network nodes of a certain group of network nodes, the particular network node checks whether it receives beacon data packets, which are sent from the neighboring network nodes at regular time intervals, from the neighboring network nodes over an interface. The relative proximity of the network nodes to each other is monitored without requiring a network infrastructure. The network comprising mobile network nodes is suitable for all applications in which spatial proximity between related members of a group is to be monitored, wherein the group members may be persons, animals or objects.
