Abstract: A device for the power adjustment of a WLAN network in a bounded space including a first WLAN module in the space, which serves to communicate with at least one second WLAN module located in the space, and at least one reference WLAN module, wherein the reference WLAN module is designed so that WLAN signals from the first WLAN module are received and a signal intensity is determined and transferred to the first WLAN module, wherein the first WLAN module is designed so the transmission power of the first WLAN module is adjusted according to the transferred signal intensity from the reference WLAN module so the received signal intensity at the reference WLAN module is less than a specified threshold value. Also disclosed is a method for the power adjustment of a WLAN network in a bounded space.

Abstract: Apparatuses, a method, and a computer program for influencing the selection of a frequency band for wireless communication with a mobile station. Disclosed is an apparatus, method, and computer program for controlling a frequency band selection for wireless communication with a mobile station in a wireless local area network—WLAN—, wherein at least a first and a second frequency band are selectable, the first and second frequency bands each having multiple transmission channels; and having a transmission circuit for transmitting at least one command to the mobile station that asks the mobile station to change from the first to the second frequency band, or vice versa.

Abstract: A method for managing a first communication connection between a first communication partner and a second communication partner. The method entails receiving a first message by the first communication partner, wherein the first message contains a command to disconnect the first communication connection. The method further entails transmitting a second message by the first communication partner to the second communication partner via a different second communication connection between the first communication partner and the second communication partner, wherein the second message contains a request to confirm the validity of the command. The method also entails disconnecting the first communication connection by the first communication partner if the first communication partner receives a third message via the second communication connection, wherein the third message contains a confirmation of the validity of the command.

Abstract: A method for authenticating a user with respect to a facility, for example, with respect to a vehicle. A signal having an item of information relating to the user is injected into skin of the user by a transmitting device. Direct contact is established between the skin of the user and a receiving device assigned to the facility, with the result that the signal is transmitted from the skin of the user to the receiving device. The user is also authenticated based on the signal received by the receiving device.

Abstract: An apparatus, a method and a computer program for a mobile device. The apparatus has a transceiver module for communication in a first mobile communication system and in a second mobile communication system and a control module to determine whether a time period until an estimated next time for replenishing an energy supply of the mobile device lies above a time threshold value. The control module uses the first mobile communication system for a data transmission if the time period lies above the time threshold value and uses the second mobile communication system for the data transmission if a connection to the second mobile communication system is available at or before the next time for replenishing the energy reserve of the mobile device.

Abstract: Apparatuses and methods for influencing the selection of a frequency band for wireless communication with a mobile station. The apparatus includes a transmission circuit that sends a beacon signal at a first transmission power in the frequency band. The apparatus also includes a recognition circuit that recognizes a connection request from a mobile station in the frequency band. The apparatus also includes a control circuit that responds to the connection request by prompting a transmission of the beacon signal at a second transmission power, which is different than the first transmission power, if the mobile station is unknown to the apparatus. Also disclosed are corresponding methods and computer programs.
