DFRobot, Arduino NB-IoT Expansion Shield

The DFRobot 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 SIM7000 Arduino NB-IoT/LTE/GPRS expansion shield is a wireless communication module produced by DFRobot and the design is based on SIMCom SIM7000 chip. This wireless communication module is designed for Arduino controllers, supporting multi-frequency LTE-FDD communication, dual-frequency GPRS/EDGE communication, NB-IoT communication.
