LPWAN London Meetup: LPWAN Use Cases

  1. 1. everything is connected LPWAN Use Cases: Making Tech Choice Yury Birchenko CTO
  2. 2. 2 • Iridium Satellite network launched November 1, 1998 • Use Case: Wireless phone calls from remote location A to remote location B • The company went into bankruptcy in nine months after launch, on August 13, 1999 • Bankruptcy filling cited "difficulty gaining subscribers"
  3. 3. 1,500 Trillion Litres annually Wasted in US agriculture 40% Water Use Reduction By precision irrigation 3
  4. 4. Prohibitively costly $500+/pcs Existing senosr monitoring solutions 4 Bulky solar panel powered Do not scale to ~ 2-3 spots/ha monitoring Proprietary / not universal designed by sensor vendors for own model range
  5. 5. Precision Agriculture Data Logger 5 Development of soil water balance model based on crop type and data from soil moisture sensors Technical • Universal (any sensor) • Long range (20km) • Compact & Easy to Connect: fits in the palm of hand, IP66, no cable glands All inputs for photosynthesis modeling • Soil moisture & temp. • Air humidity & temp. • Solar radiationKey objectives • save hundreds of pounds per hectare on irrigation • early yield prediction and management
  6. 6. 40% More Parking Revenue for Cities 30% less driving 10% CO2 reduction 6
  7. 7. 7 Extreme IoT Challenge Detection Accuracy > 99% Mechanical Design
  8. 8. Data Analytics Prize: 28 bays at Finsbury Square, London • Average Stay Duration – 72 min • Average Bay Utilisation - 54% • Total Value of Stays £5K/week • More than 100 overstays per week 8
  9. 9. 9 • The handsets could not operate as promoted until the entire constellation of satellites was in place • Reception indoors was difficult and the bulkiness and expense of the hand held devices when compared to terrestrial cellular mobile phones discouraged adoption • Source: Wikipedia
