A DATA TRANSMISSION APPARATUS AND A METHOD FOR ACTIVATING A DATA TRANSMISSION

摘要

A data transmission apparatus (100) has a data transmission device (110) and a wakeup receiver (120). The data transmission device (110) can be activated in order to change from an idle state to an operating state and in order to perform a data transmission (200) with a communication partner in the operating state. The wakeup receiver (120) is designed to be ready to receive an initiation signal (125) during the idle state of the data transmission device (110) and to activate the data transmission device (110) in response to the initiation signal (125). The wakeup receiver (120) is also designed to extract a data transmission information item (230) from the initiation signal (125) in order to ascertain a time for activating the data transmission device (110) on the basis of the data transmission information item (230) or to activate the data transmission device (110) such that the data transmission device (110) performs the data transmission (200) on the basis of the data transmission information items (230).
