19 19  NarrowBand-Internet of Things (NB-IoT) is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services. NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency, especially in deep coverage.
20 -\\NLMS01 supports different uplink methods include **TCP,MQTT,UDP and CoAP  **for different application requirement.
21 -\\NLMS01 is powered by  **8500mAh Li-SOCI2 battery**, It is designed for long term use up to 5 years. (Actually Battery life depends on the use environment, update period & uplink method)
22 -\\To use NLMS01, user needs to check if there is NB-IoT coverage in local area and with the bands NLMS01 supports. If the local operate support it, user needs to get a **NB-IoT SIM card** from local operator and install NLMS01 to get NB-IoT network connection
