2. 0.3-22 kbps
2-3 km in urban areas,
6-10 km in rural areas
A battery can live 3 years,
while sending every 5
minutes
What is LoRaWan?
Low-Power Wide-Area Network (LPWAN) or Low-Power Network (LPN)
is a unlicensed wireless telecommunication network designed to
allow long range communications at a low bit rate among low
power things (connected objects), such as sensors operated on a battery.[1][2]
This allows for long-lived & cheap sensors, which cost ~ 25 EUR.
Suitable where Wifi, Bluetooth or *G networks are not available.

3. What is the TheThingsNetwork?
A Layer on top of
LoRaWan, which
allows your
application to work
with sensors
without needing to
worry about the
infrastructure.
• Consists of
Nodes, Gateways
& the backend

4. Existing LoRaWan Network in Bern
 check thethingsnetwork.org

5. Test LoRaWan Coverage
• Ttnmapper.org visualizes
range of existing LoRaWan
network
• This helps to find areas with
low network coverage.
• Intersting approaches to
measure network coverage:
put tracking devices on e.g.
busses or garbage trucks

6. How do nodes look like?
 based on the Stuttgarter Citizen Sensors  E.g. based on the fine dust sensor of
https://luftdaten.info

7. The tracker node in detail

8. A number of test development boards is out
(e.g. BadgerBoard, LoPy, RFM95)

9. Example data record from tracking device

10. Data can be consumed in many ways
• TheThingsNetwor
k delivers
incoming sensor
data via MQTT
and REST API.
• Colleagues at SAP
IoT Services built
an integration
with SAP IoT
services.
