The LoRa is a novel radio communication technology
providing low power and a high range of data transmission.
The LoRa transmission may be used for a low-cost localization
to estimate the network nodes’ location. Some recent research
showed that the location could be found with reasonable accuracy,
with median error as low as tens of meters. Still, such results are
achieved in a controlled environment with low interferences. We
first evaluate the LoRa localization using an extensive data set
of a telemetric network of a few thousand devices. We show that
although the direct positioning based on trilateration provides
limited accuracy, the measurement of LoRa transmission may
be successfully used to evaluate the credibility of location information.
The information about which gateways received the data
and the RSSI measurements allow us to verify if the potential
coordinates of a location are accurate. We propose a metric for
location verification and estimate its credibility on a sample of
measurements from the LoRa telemetry network.
