LoRaWAN in temperature monitoring
The technology that carries the measurements from the data logger to the gateway. Long range, low power consumption and its own network, independent of your IT.
What is LoRaWAN?
LoRaWAN is a wireless network standard for devices that send small amounts of data over long distances using very little power. The name stands for Long Range Wide Area Network.
The technique behind it is that the signal is spread over a wide frequency band. That makes it robust against noise and makes it possible to reach far with low transmission power. The trade-off is low speed, but that does not matter when you are sending a temperature reading and not a video.
In a monitoring system, this means each data logger can transmit to the gateway without a cable and without loading your network, and that the battery lasts a long time, because the radio is only on for a moment at a time.
Range depends on the building. We measure on site before we promise anything.
What LoRaWAN means in practice
Long range
Up to 15 km in open air, typically 1 to 2 km in a building, and considerably less in basements and behind metal.
Low power consumption
The radio is only on for a moment at a time. That is why a battery-powered logger can run for a long time without replacement.
Its own network
Runs independently of your IT network. Only the gateway needs to be connected, and it requires Ethernet.
Low speed, high robustness
The technology is optimised for small amounts of data. A temperature reading takes up next to nothing.
Many devices per gateway
Up to 50 data loggers and 100 to 200 sensors on one gateway.
Easy expansion
A new logger requires no cabling and no change to the infrastructure.
Why do we use LoRaWAN, and what is it?
LoRaWAN runs on its own network, requires no setup on your IT network and reaches far through walls. We use Wi-Fi for smaller installations and fast logging.

Is LoRaWAN secure?
Communication is encrypted at two levels, between device and network and between device and application. The security of your overall setup is assessed together with IT.
Does it interfere with hospital equipment?
LoRaWAN transmits at low power, and the equipment is CE, FCC and IC approved. Specific considerations are agreed with your technical department.
How many gateways do we need?
Typically one per building. Metal racking, basements and reinforced concrete dampen the signal, so we measure on site.
What happens if the gateway goes down?
The data loggers keep measuring and store data locally for up to 28 days. The measurements are synchronised when the connection is back, so there is no gap in the curve.
Do we have to run the network ourselves?
No. The gateway is the network, and we set it up. There is no subscription with a telecoms provider.
