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 rural setting © ttnmapper.org , Open Street Map
9. INSANELY LONG RANGE (under extreme conditions) 201 km ground-to-ground by Andreas Spiess, TTN Basel http://www.sensorsiot.org/ © ttnmapper.org

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
