1 Bring the value of Smart-Grid to end-users with Long range / Low power radio communications Aleksander TRACZYK Head of Business Services at Enel France «Making Energy user smarter» Olivier HERSENT CEO at Actility

2 The IoT Graal : Ultra-long range bidirectional communication within ISM power limits Probability of Gaussian variable to exceed value x Bit error rate Received power Information rate (bit/s) For a given reception power: When D (bit/s) decreases, Pe also decreases

3 The problem with low bitrate Range increases with energy per information bit. At given RF power budget, long-range implies low bitrate For traditional modulation technologies, low bitrate means narrow spectrum A 30PPM quartz may deviate as much as 25kHz on a 868MHz frequency FSK connectivity becomes somewhat random below 20kbps!

4 Spread spectrum backgrounder (1) Originally used for military communication, spread spectrum transceivers transmit a known pattern of bits for each information bit. «0» « » «1» « » RF spectrum is «spread» accordingly

5 Spread spectrum backgrounder (2) Receiver : incoming signal is multiplied by the known pattern Chips +1/-1 «1» reference pattern High complexity (synchronisation, doppler ) Signal bits add up, noise bits cancel each other the information bit is recovered

6 Tests in dense city : Paris 14dBm (ISM regulation), 868MHz, from rooftop GSM site 2km indoor range at ground level!

7 AUTONOMY Towards the Internet THINGPARK WIRELESS of Things YEARS wmbus CELLULAR WiFi DAYS <1kbps <10 >100kbps THROUGHPUT MODULE COST

8 ThingPark Wireless : a complete solution Long Range M2M & IoT: 2km to indoor Long Range & Low-Power bidirectional connectivity breakthrough performance for industrial automation, Smart Grid, Smart Cities & connected appliances Network manager for public base stations and femto cells Private base stations Sensors and Modules

9 Enel France Vision We will have Smart Grids. We will have Smart Buildings. We will have Smart factories So we need Smarter Energy User We empower our Customers with Advanced Energy Monitoring Systems

10 Business challenges Business Challenges Enel France Approach Easy to install measurement devices Propose wireless devices leveraging the latest Telco and Internet technologies easy to install, maintain or remove Get efficient analytics tools Propose a Web-based monitoring platform with fully customized on-demand reports and alarming system Find-cost effective solutions which do not affect customer s Capex capabilities Propose a pay-per-data subscription model

11 Advanced Energy Monitoring

12 Example of the web platform

13 Example of the TV display (1/2) Office building 250 GOAL : 150 kwh/m²/an Sed pellentesque volutpat sem vel tristique. Pellentesque congue iaculis justo malesuada tempus. Vivamus tincidunt risus id erat imperdiet, id hendrerit nisi fermentum Energy Consumption per square meter (kwh/m²/year) 450 Day goal 5 oct. 6 oct. 7 oct. 8 oct. 9 oct. 10 oct. 11 oct. Last 7 days - Intraday reporting (Wh/m²/day) Powerded by Enel France Services

14 Example of the TV display (2/2) Factory GOAL : reduce the factory electricity consumption during off production hours (20h-6h) Changes since last night Others -2% Sed pellentesque volutpat sem vel tristique. Pellentesque congue iaculis justo malesuada tempus. Vivamus tincidunt risus id erat imperdiet, id hendrerit nisi fermentum.
