FIWARE Global Summit - Introduction to LoRa Alliance and Technology

  1. 1. Introduction to LoRa Alliance and technology FIWARE SUMMIT May 8th, 2018 in Porto
  2. 2. 2 LPWAN MARKET: COMPLEMENTARY TECHNOLOGIES FOR WIDE VARIETY OF MARKET APPLICATIONS Image Credit: MultiTech CONNECTED DEVICES: ACCESS LAN Short Range Communicating Devices CELLULAR Long Range w/ Power Traditional M2M LOW POWER WAN Long Range w/ Battery Internet of Objects 3G+/H+ 4G Well established standards Good for: Mobile, In-home, Short range Not good for: Battery life, Long range Good for: Long range, High data-rate, Coverage Not good for: Battery Life Well established standards Good for: Long range, Long battery, Low cost Not good for: High data-rate Emerging PHY standards
  3. 3. 3 LPWAN Market Update LoRaWAN™ is demonstrating its readiness across multiple vertical markets LoRaWAN market is maturing from the sensor up with the magic combination of sensors that are: Growth in quantity of easily deployable, complete solutions for specific verticals LONG LIFE AVAILABLE IN VOLUMES COST EFFECTIVE GLOBAL REACH OF PUBLIC AND PRIVATE DEPLOYMENT MODELS MULTI-PURPOSE OR USE-CASE SPECIFIC OPPORTUNITIES TO ENABLE NEW ROAMING MODELS
  4. 4. 4LPWAN Techology Stack Leveraging LoRa® and LoRaWAN™ • LoRaWAN™ is an open networking protocol that delivers secure bi-directional communication, mobility and localization services • LoRa® is the physical (PHY) layer or the wireless modulation used to create the long-range communication link LoRa® is a registered trademark of Semtech corporation.
  5. 5. LoRa Benefits for the internet of things
  6. 6. 50 kbit/s KEY PRINCIPLE ENABLED WITH LORA: VARIABLE BITRATE TO OPTIMIZE SENSITIVITY AND TIME ON AIR Low rate Fast rate The slower the transmission is, The better the sensitivity and penetration in building can be. RANGE ENERGY « SF12, 11, 10» The faster I can transmit, then the lower energy I consume, and the longer the battery life will be. « SF 5, 6 ,7, FSK» Different datarate « Spreading factor » SMART CAPACITY Several km range in line of sight on outdoor Hard to reach endpoints in deep indoor A few km range Long battery autonomy Indoor/Outdoor 300 bit/s Source: Semtech

  8. 8. LoRaWAN supports 3 communication classes for the end node 5/14/18 « ALL » « BEACON » « CONTINUOUS » Use case examples: Smart bin – Smart water meter Reports status/index a few times per day. Few uplinks and downlinks for extremely low energy Temperature sensor - smart meter with valve Reports frequent levels of moisture, temperature,etc. Turns valves on or off with some latency. Few uplinks and downlinks per day. Street Lighting For remote monitoring and actuation, plus reports for maintenance and status a few times per day. Constantly listens for network command with low latency actuation. Source: Semtech

  13. 13. 132017 LoRa Alliance Key Facts & Figures
  14. 14. Fastest-Growing Global Technology Alliance 14
  16. 16. 16 Focused on end-user adoption Technology is market-ready • Alliance has a strong track record of membership growth • Now, we’re leveraging our broad ecosystem to showcase LoRaWAN o Accessibility o Availability o Easy of Use o Real-world Readiness • Wide range of end-to-end solutions are deployed and in development, as all key infrastructure pieces are proven across a variety of counties
  17. 17. • Confidence & Reliability • End-user reassurance that the device works as intended • Reduced support costs • Prevent product failure “later,” when more expensive to repair • Marketing • Mark of quality and supported by promotional activity • Cost impact on operations • Poor device performance increases number of gateways needed BENEFITS OF LoRaWAN™ CERTIFICATION & RF Performance Testing 17 Why Certifying is So Valuable:
  18. 18. 18Millions of LoRaWAN™ Devices • Large member ecosystem actively developing LoRaWAN products • Products deployed in wide range of vertical markets • Products leverage global LoRaWAN network coverage • Real solutions being delivered now across a wide range of use cases
  19. 19. 19Geolocation: differentiating feature of LoRaWAN Comparison of Geolocation Technologies LoRaWAN TDOA/RSSI Lowest cost solution Works natively with any LoRaWAN sensor LoRaWAN enables long battery life use cases TDOA: 20-200m accuracy range depending on conditions RSSI: 1000-2000m accuracy Wi-Fi Location Cost efficient solution for outdoor and indoor solution Accuracy increases with hotspot density BLE Requires a BLE beaconing system Indoor solution GPS/AGPS 1 GPS adds $5-$10 to the BOM Most accurate but power consuming solution AGPS brings battery consumption improvement GPS does not work indoors Image credit: LoRa Alliance Geolocation Whitepaper, Jan. 2018
