LPWAN’s are a new class of connectivity technologies for use with Internet of Things (IoT) devices and battery-operated sensor applications. Commonly used LPWAN standards are LoRaWAN, Sigfox, and the emerging cellular standards NB-IoT and CAT-M. They all have long range (up to 10 kilometers), low power (battery lifetime of 5+ years) and low bandwidth, which is fine for most sensing applications.
