  1. Mobile wireless communication for metering (smart and industrial) and smart grid Detlef Einacker, November 2010

  2. Intro: GSM/GPRS/EDGE/UMTS Industrial metering Smart metering Smart Grid Appendix

  3. Data transmission GSM (CSD) vs. GPRS/EDGE/UMTS GSM Fixed assignment of voice and data channels Physical connection to the air Full bandwidth of a radio channel used exclusively by one user User pays the radio channel the whole time of allocation Pricing according to connection time - “pay for silence” GPRS/EDGE/UMTS • Dynamic assignment of voice and data channels • Data transfer via packages • GPRS session uses several channel in parallel • Resources are only occupied for the absolute period of time to transmit the data package • Pricing according to transferred volume - “pay for activity”

  4. GPRS/EDGE – a few details Source: T-Mobile Dynamic assignment of voice and data channel. GPRS/EDGE Session is able to use several channel in parallel. Resources are only occupied for the duration of transmission. GPRS/EDGE use existing GSM infrastructure GPRS/EDGE is a technology for packet oriented data communication (IP) GPRS/EDGE is global and area wide packet-switching data GPRS/EDGE Session 1 Combined voice and GPRS/EDGE data channel Dedicated GPRS/EDGE data channel GPRS/EDGE Session 2

  5. UMTS – Core Netzwerk UMTS is using it‘s own radio access network, separated from GSM UMTS is using W-CDMA (Wideband Code Division Multiple Access) air interface standard The UTRAN Network logically cuts into RNSs (Radio Network Subsystem) A RNS is a geographical region which is managed by a RNC (Radio Network Controller). Single RNS‘s can be cuts into Location Areas (LA) MSC, SGSN and GGSN are core components of GSM/GPRS 2G network and are used by the UMTS 3G network.

  6. Comparison of wireless communication The acutal values of mobile service providers may differ from these values.

  7. Intro: GSM/GPRS/EDGE/UMTS Industrial metering applications Smart metering applications Smart Grid applications Appendix

  8. Industrial Meter communication • Can we read transparent different meter types with one modem? • Is it possible to keep the already installed meters? • How do we avoid meter reading mistakes? • Can we assure save and protected meter reading, protection against fraud? • Is it possible control and manage meter and modem remotely, without regular visits?

  9. Remote Meter Reading Any meter! ZDUE Transparent and bi-directional Telecommunication Network GSM, GPRS, PSTN or LAN Control Centre and remote configuration

  10. Remote Meter Reading Any meter! • Reduce meter reading mistakes • Reduce meter reading costs • Reduce Risks, stay in office • Reduce Confusion and Fraud through automated processes with security • No vendor log in through transparent communication ZDUE Transparent and bi-directional Telecommunication Network GSM, GPRS, PSTN or LAN Control Centre and remote configuration

  11. Products for industrial meter reading – ZDUE modems Product Advantages Application Areas • Utilities • Meter reading ZDUE-MOD-PLUS-V Meter reading via Analog • Interfaces CL1; RS232; RS485 • time window for call acceptance • Integrated real-time clock • Auxiliary power supply • Status information through LEDs • Security through Password ZDUE-GSM-PLUS-V Meter reading via GSM and GPRS • Quad Band GSM • Interfaces CL1; RS232; RS485 • time window for call acceptance • Auxiliary power supply • Status information through LEDs • Security through Password • Utilities • Meter reading ZDUE-GPRS-PLUS-IV Meter reading via GSM and GPRS • Interfaces CL1; RS232; RS485 • Very short reading intervals • Password protection • Status information through 4 LED‘s • Configuration locally and remote • Utilities • Meter reading ZDUE-LAN-PLUS-IV Meter reading via LAN (DSL) • Interfaces CL1; RS232; RS485 • Very short reading intervals • Status information through LEDs • Password protection • Log file system • Utilities • Meter reading

  13. Smart Meter communication • How do we connect single households for smart metering? • Can we avoid vendor and product log in scenarios? • Is it possible to read all meters (e,g,w, ACs, heating, etc.), to connect also the home automation or displays? • Can we get open standard and interoperable solutions?

  14. Smart Metering, with a gMUC (WAN comm. gateway) CCO Customer interface: Ethernet or radio GSM GPRS Radio: W M-Bus or Zigbee @ Ethernet, LAN / DSL PLC RS232 or RS485

  15. gMUC/MUC Product range available • gMUC-GPRS • Installations mainly for single customers and/or rural environment • Communication with GPRS towards the central system • W-MBUS, 1107, RS232, RS485 (planned: DLMS, ZigBee) • gMUC-LAN • Communication via DSL line modem towards central system • Installation and operation through telecom operator • MUC-C-GPRS (following German standard) • Installations mainly for single customers and/or rural environment • Communication with GPRS towards the central system • MUC-C-PLC (following German standard) • Installation mainly in residential buildings or urban environment • Communication with PLC to the MUC-concentrator • MUC-Concentrator (following German standard) • Installation mainly in urban substations • Communication with PLC towards MUC-C-PLC • Communication with GPRS/EDGE towards the central system

  17. Smart Grid communication • How can we control the remote networks and grids? • How to connect outside substations secure, reliable and easy? • Can we avoid vendor lock-in? • How to build virtual IP rings for redundant communication? • We need state of the art security with firewall and VPN functionality! Via mobile networks?
