  1. THE ROAD TO OPEN NETWORKS Building an open and free

    Internet of Things network casas@arch.ethz.ch | twitter.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.  TECHNOLOGY  COMMUNITY  SOCIAL CHANGE

  5. WHAT IS LORAWAN?

  6. 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
  7. LORAWAN 3 * 10 10 km range 10 USD/node 10

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

  11. 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
  12. FREE & OPEN SOURCE STACK

  13. UNLICENSED SPECTRUM Anyone can deploy a LoRaWAN network!

  14. 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
  15. 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

  39. THE WORLD RUNS ON OSS

  40. CAN I TRUST… …the gateway won’t be shut down? REDUNDANCY

    …sensitive information stays private? CRYPTOGRAPHY …the backend to be up-and-running? DECENTRALIZATION
  41. CAN I TRUST… …it will be around in a few

    years time? OSS + OPEN STANDARDS
