Data transmission arrangement comprising: energy supply means for supplying the data transmission arrangement with electrical energy; means for determining payload data provided by a sensor element connected to the data transmission arrangement; means for channel coding of the payload data so as to obtain channel-coded data; means for splitting up the channel-coded data into a plurality of data packets having a code rate smaller than one; and means for transmitting data packets which is configured to transmit the plurality of data packets via a communication channel with a time lag, so that there are non-transmission periods in between the data packets during which no transmission is performed, only in the case that an amount of electrical energy that can be provided by the energy supply means is sufficient for transmitting the respective data packets with a predefined standard transmitting power; the energy supply means comprising an energy harvesting element for non-line-conducted energy extraction from the environment of the data transmission arrangement; the energy supply means comprising an energy store for storing the energy extracted by the energy harvesting element, the energy store being configured for short, pulse-like load; the means for transmitting data packets being configured to select the time lag with which the data packets are transmitted such that the energy store of the energy supply means is subjected to a short, pulse-like load; the means for transmitting data packets being configured to either - transmit a data packet, which is about to be transmitted, of the plurality of data packets at a reduced transmitting power if an amount of electrical energy that can be provided by the energy supply means is sufficient for transmitting the respective data packet at the reduced transmitting power, the reduced transmitting power being reduced by a maximum of 40 dB as compared to the standard transmitting power; or - not transmit or to transmit with delay a data packet, which is about to be transmitted, of the plurality of data packets if an amount of electrical energy that can be provided by the energy supply means is not sufficient for transmitting the respective data packet. energy supply means for supplying the data transmission arrangement with electrical energy;
