LPWAN stands for Low Power Wide Area Network. An LPWAN network meets the following criteria: it is a wireless network, which allows communication with the network with low energy consumption. The network has a large range (several kilometers) with a low bit rate.
An LPWAN’s main purpose is to collect information. Although it is often possible to send information in both directions. There are different types of networks that meet these criteria and thus fall under the name LPWAN, such as LoRaWAN, NB-IOT and LTE M.
