I will test 900 MHZ band NB-IoT 3GPP Arduino shield development device from AIS in Thailand which I just ordered today for a bit over $30 USD. I want to see if it can penetrate the building and connect to the 3GPP network. If not, I can use it for developing "sensor network projects" in my lab.
I think I will also test the same device from another local provider, TRUE after I test the AIS shield above.
Also, I have an appointment with the Communication Authority of Thailand (CAT) to discuss LoRaWAN penetration early Jan after the holidays, both as a service from CAT and to set up an unlicensed LoRaWAN network with private gateway as well.
