Abstract: A transmitter for sending data packets over a time-multiplexed channel includes a time slot selector for selecting a time slot for transmitting a data packet; and a data packet position selector for selecting a data packet time position within the selected time slot, wherein the data packet time position is selected anew for at least every ith data packet. The transmitter is configured for transmitting the data packet in the selected time slot and the selected data packet position within the selected time slot. A method for transmitting data packet is also disclosed. Furthermore, a receiver, a method for receiving data packets and a computer program are additionally described.

Abstract: A data transmission device has a data transmitter and a wake-up receiver. The data transmitter is activable to change from an idle state into an operating state and to execute a data transmission with a communication partner in the operating state. The wake-up receiver is implemented to be ready to receive an initiation signal during the idle state of the data transmitter and to activate the data transmitter in response to the initiation signal. The wake-up receiver is further implemented to extract data transmission information from the initiation signal to determine a time for activating the data transmitter depending on the data transmission information or to activate the data transmitter such that the data transmitter executes the data transmission depending on the data transmission information.

Abstract: A device for determining a device position, which includes a receiver for receiving signals of a plurality of transmitters and a determiner for determining reception powers of the signals of the plurality of transmitters. The device further includes a provider for providing transmitter positions of the transmitters on the basis of the signals of the plurality of transmitters. The device further includes a determiner for determining a first position of the device on the basis of the transmitter positions, wherein the determiner for determining the first position is further formed to determine transmitter directions on the basis of the first position and the transmitter positions, and to determine a second position of the device on the basis of the transmitter directions, the transmitter positions and the reception powers.
