Narrowband IoT (NB-IoT or LTE Cat NB1) is a low-power wide-area network (LPWAN) radio technology standard developed to enable a wide range of devices and services to be connected using cellular telecommunication bands. It is one of a range of Mobile IoT (MIoT) connectivity technologies standardized by the 3rd Generation Partnership Project (3GPP) which also includes enhanced Machine-Type Communication (eMTC or LTE Cat M1) and EC-GSM-IoT particularly designed to fit Internet of Things (IoT) and machine-to-machine (M2M) communications. The (P-L496G-CELL02) discovery pack for LTE IoT cellular to cloud (STM32-C2C/LTE IoT) is a turnkey development platform for cellular and cloud technology based solutions.
