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

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

3 AMI WAN NAN HAN/LAN Primary, secondary, tertier Local, last mile, ?

4 HAN/LAN Gateway Home area network

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 ((( )))

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 EN13757-4:2005 “Stationary Mode” S “Frequent transmit mode” T
Unidirectional, S1, or bi-directional, S2 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

29 IEC/ISO and EN standard Supporting media (RF, PL, TP, IP)
KNX is the worldwide standard for home and building control (~7000 certified products) IEC/ISO and EN standard Supporting media (RF, PL, TP, IP) KNX is a registered Trademark of the KNX Association cvba, used with kind permission

30 RF KNX-RF has the same lower layers as wireless M-Bus KNX RF
868 MHz, multiple channels New version of standard just released Improvement in battery lifetime and performance improvement in noisy environment

31 ZigBee is a registered Trademark of the ZigBee Alliance

32 ZigBee basics Short range radio based on IEEE 802.15.4
2.4 GHz Mesh radio Limited to 10 mW/MHz in Europe by EN

33 ZigBee Smart Energy Public Application profile for support of
Meters Display Repeater Load Control Devices Demand response support Security to allow consumer only, utility only, or shared networks ZigBee Smart Energy : Preferred solution in US. for Smart Energy HAN

34 Smart Energy Security Security is critical requirement
AES128 bit network key and link keys Preconfigured link key Used to receive network key Certificate based public key exchange to achieve final link key Utilizes a Certificate Authority for the device keys Process has been independently audited and approved by Carnegie-Mellon

35 The way forward: ZigBee IP stack
New ZigBee stack option in development Based on end to end IP for smart metering MAC – with MAC security 6LoWPAN

36 6LoWPAN Standardized through IETF
