Abstract [en]

In this master thesis we study and implement the wireless M-Bus protocol (the wireless variable of standard M-Bus). We acquired measurements from an electricity and water meter over wM-Bus. Specifically for the electricity meter, a ZigBee/wM-Bus gateway was implemented. The implementation includes two sub- modes of wM-BUS, S1m and N1b for both meters. S1m-mode functions in the 868 MHz frequency band whereas N1b mode functions in the 169 MHz band. The measurements were reported over serial communication to a BeagleBone or a PC for further exploitation. Range test were performed for the 169 MHz frequency band. AES-128 CTR encryption was also applied to the packets exchanged.
