Setup

LoRaWAN End Node -> Attenuator -> Dynamic Attenuator -> LoRaWAN Gateway -> Zenner Plattform

The End Node must be tightly sealed in a shielded metal enclosure. The battery must be included in the enclosure. In order not to leave any gaps, the housing should be screwed tightly.
For the test, the output power of 14dB was used. As attenuation 80dB + 5 to 55dB (dynamic) have resulted as reasonable values.

Notes

Each test was repeated 100 times. Check boxplots if more tests are necessary.
Export packets from the Zenner Plattform via Webinterface. API not available.
Python and Regex knowledge required.
