Abstract: The present invention relates to a device and a system for transmitting data messages which can be received by different types of receivers. A device and system are disclosed where data transmissions are based on data messages (2) comprising two parts, a first part (20) being encoded in accordance with a communication protocol, such as the wireless MBus protocol, and a second part (21) which comprises error-correcting information for enabling a receiver device to correct errors in the data message (2), such as parity information related to turbo coding. The first part (20) forms an independent sub data message which can be received independently of the content of the second part (21). The sub data message can be received as is within a first communication range (6), and the entire data message can by virtue of the error correction information, and subsequent error correction, be received within a second longer communication range (7).
