1 Open wireless standards Wireless M-Bus, KNX RF, ZigBee, 6LoWPAN Hallvard Moholdt, Technical Solutions Manager Ørjan Nottveit, Product Line Manager

2 Agenda AMI overview Wireless M-Bus NTA8130 OMS KNX RF ZigBee Total cost of ownership (TCO) Q&A

3 HAN/LAN NAN WAN AMI

4 HAN/LAN Gateway

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

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

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

10 Background Standardization work -> Cenelec, TC 294 EN standard Comm. Syst. for remote reading of meters EN :2005: Wireless Meter Readout -3 M-Bus application layer -1 DLMS application layer The Netherlands: NTA8130 as of Feb 2006 (last revision of Jan 2009) Germany: OMS specification released September 2009 TC 294 again active (re-launched July 2009)

11 EN :2005 Stationary Mode S Unidirectional, S1, or bi-directional, S kb/s, MHz Frequent transmit mode T Unidirectional, T1, or bi-directional, T2 100kb/s, MHz Frequent receive mode R 10 channels, 4.8 kb/s

12 NTA 8130 (DSMR) Netherlands Technical Agreement 8130 Dutch Smart Meter Requirements P2 interface Max 4 metering instruments and/or grid company equipments in each metering system Defines T1 / T2 and AES128

13 OMS Open Metering System specification Assured co-existence with NTA 8130 / DSMR Unified approach for the different media (electricity, gas, heat and water) as well as actuators and displays Interoperation Optimized for battery lifetime of > 14 years Installation supported

14 OMS cont. MUC (Multi Utility Controller): Intelligent concentrator between AMM and the devices Either S or T mode and AES 128 encryption MUC meters OMS is being reviewed by CEN as European new work item proposal TC294
