The first deployments of IoT wireless sensors had shown the importance of battery operation. Without a very long battery life, the operating costs of a wireless sensor have quickly destroyed many potential business models. To meet the increasing demand for energy-saving techniques, several Low Power Wide Area Network (LPWAN) wireless technologies such as Sigfox, LoRa and LTE Cat NB1 (NB-IOT) have been developed.
