Today, LPWAN has cellular (licensed band) and non-cellular (unlicensed) technologies. Under the cellular category we have NB-IoT and LTE-M and in unlicensed, the popular categories are LoRa (Long Range) and SigFox (IoT Technology company and it uses the SigFox protocol). LoRa and SigFox need communication gateway which aggregate IoT sensor data to the IoT platform through their own private networks. NB-IoT and LTE-M don't need communication gateways and hence it is cost effective.
