@descartes I am not to bothered spending a few euro on a test setup. So having one or two GWs for testing and a hand full of clients would be OK. The data collected would be mostly environmental and possibly also downlink to react to a value I read back. LoRaWAN is pretty much the only possibility short of using dedicated 8xxMHz ISM band modems with RS232. For “good times” I can easy use devices such as Wireless Point to Point links but I need something more resilient and only low bandwidth. The Airtime limitations are kind of weird. If I for example need to read 5 values and send them from one device I might be bad on Airtime, Yet if I have 5 devices sending those 5 values I am OK if I understand the limits correct.
Well, I fight my OTAA issue 1st, that appears to be the most pressing now to avoid that counter issue I had with ABP and then deploy a few devices to see how I get on with Airtime.

PS: What other tech than LoRaWAN would consider as alternative ?
