According to the NB-IoT Arduino device (library) (https://github.com/AIS-DeviceInnovation/AIS_NB_BC95) I just ordered, after it is registered with AIS (the service provider), we can send UDP messages...

Update:

Still sorting out the laws and regulations in Thailand, which recently changed (yet again).

It seems we can transmit more power at 923 MHZ than at 433 MHZ (and other regulatory...

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...

Initial research shows that LoRa in the range of 433 MHz has a short range and poor urban (penetration). The best results seem to come from LoRa frequencies in the 900 - 925 MHz band.

However,...

Bad news. Looks like the Thai government has decreed the "long range (LoRA) band" (in modern, developed countries) to be the RFID short range band in Thailand; it's all very confusing here; but it...

My favorite projects are always related to the "latest" tech in command and control, networking and network communications. This Elecrow GSM/GPRS/EDGE SIM5360E 3G Shield seems to be the "latest...
