  1. THE THINGS NETWORK Switzerland community gonzalocasas@gmail.com @gnz

  2. THE THINGS NETWORK A global community, building open source software

    and hardware to operate a crowd-sourced IoT network.
  3. IN SWITZERLAND

  4. WHAT IS LORAWAN?

  5. LORAWAN • LoRa (Long Range): Radio modulation technique • LoRaWAN:

    MAC protocol for Wide Area Networks (OSI Layer 2 and 3) sensors nodes gateways backend application backend LoRa ip ip
  6. LORAWAN 3 * 10 10 km range 10 USD/node 10

    years battery life
  7. LONG RANGE 2km - 5km in urban setting 40km+ in

    rural setting © ttnmapper.org , Open Street Map
  8. INSANELY LONG RANGE (under extreme conditions) 201 km ground-to-ground by

  9. INSANELY LONG RANGE (under extreme conditions) 333 km air-to-ground (helium

  10. LOW COST Node/transceiver: CHF 8.5 Gateway: ~CHF 250 (indoor) Open

    source stack + ISM bands Low CAPEX, almost negligible OPEX Photos by @gnz, CC-BY-SA
  11. OPEN SOURCE BACKEND

  12. UNLICENSED SPECTRUM Anyone can deploy a LoRaWAN network!

  13. LOW POWER Class A Class B Class C Always send,

    receive after send. Up to 10 years. Deep sleep: ~10 μA TX ~40 mA RX ~14 mA Time-synchronized receive windows. Always-on receive mode. Not supported Support not ready, but planned
  14. LIMITATIONS Bandwidth Payload size Regulatory limits 0.3 bps to 50

    kbps 51 bytes (DR0)
 222 bytes (DR4) Fair usage policy 1% Duty Cycle 30 seconds/day airtime
 10 downlinks/day
