5. Why open standards Open standards enable interoperability
Open standards give multi-vendor ecosystem and hence lower cost
What are open standards
EN/IEC/ISO
IETF
Industry standard

6. Wireless M-Bus

7. figawa,

8. Wireless M-Bus 3 Key points
Only European Norm for wireless metering
Field proven in millions of meters
Supported by all major metering companies in Europe

9. Wireless M-Bus Basics Slaves reporting to Master (concentrator)
Slave receives acknowledge with minimum time response
((( )))
Message decryption and acknowledge within 2-3 ms
((( )))
((( )))
Meter wakes up and transmits reading (gas: each 30 min)
((( )))
((( )))
Water: TX each 4 hours (with random time-spread)
Ack can contain ’shut valve’ command
