Embodiments provide a data transmitter. The data transmitter comprises a device for generating transmission data packets which is designed to divide a first data packet intended for a first data receiver into a plurality of transmission data packets wherein each of the transmission data packets intended for the first data receiver is shorter than the first data packet. Furthermore the data transmitter comprises a device for sending data packets which is designed to transmit the transmission data packets intended for the first data receiver at a time interval via a communication channel. The device for sending data packets can be designed to be
- Send at least one further transmission data packet to the first data receiver or a second data receiver in the time interval between the plurality of transmission data packets intended for the first data receiver; or
- A pending transmission data packet of the plurality of transmission data packets not to send only partially or later if at the time of sending the one transmission data packet another transmission data packet is pending for transmission; or
- A pending transmission data packet of the plurality of transmission data packets in response to external conditions not only partially or later to send; or
A transmission data packet pending for transmission of the plurality of transmission data packets is not to be transmitted only partially or later via the communication channel if at the time of transmission of the data packet a fault or transmission is detected by another data transmitter.
