NB-IoT (Narrow Band-Internet of Things) technology is a new IoT technical branch and supports cellular data network connection of low power consumption device in WAN (Wide Area Network), which also called as LPWAN. NB-IoT operates in authorized frequency spectrum. It can be directly deployed to GSM, UMTS, LTE without any interference of current networks, while the bandwidth consumption is just about 180KHz.
This SIM7000E Arduino NB-IoT/LTE/GPRS expansion shield is a wireless communication module produced by DFRobot and the design is based on SIMCom SIM7000E. This wireless communication module is designed for Arduino controllers, supporting multi-frequency LTE-FDD communication, dual-frequency GPRS/EDGE communication, NB-IoT communication. No matter prototype developments or small-batch productions, SIM7000C Arduino NB-IoT/LTE/GPRS expansion shield is the best solution to applications of low power consumption, low latency and meddle-throughput. Besides onboard GNSS (Global Navigation Satellite System), SIM7000E supports American GPS, Russian GLONASS, European Galileo, Japanese QZSS and Chinese BeiDou Navigation Satellite System. It can be widely applied to IoT applications such as long-distance control, moving tracking, long distance data uploading and shared bikes.

The SIM7000E Arduino NB-IoT/LTE/GPRS expansion shield supports both SIM card and NB-IoT card synchronously. You can plug in a common SIM card to achieve traditional GSM applications, such as make a phone call and send message. You can also plug in a NB-IoT card to realize NB-IoT data transmission. Besides, this expansion shield provides a BME280 environmental sensor. So it could be a prototype to develop NB-IoT projects, monitoring temperature, humidity and pressure.
