Raspberry Pi 3 B+ SIM7000C NB-IoT/eMTC/EDGE/GPRS/GNSS Expansion Board 4G Communication
Note: Since the NB-IoT is divided into different frequency bands, the current sales version is the Asian version, and the Asian version is limited to use in Asia. This product does not include the Raspberry Pi module and needs to be purchased separately.
【product description】
The product is a tree with NB-IoT (narrowband Internet of Things), eMTC (Enhanced Machine Class Communication), EDGE (Enhanced Data Rate GSM Evolution), GPRS (General Packet Radio Service) and GNSS (Global Navigation Satellite System) functions. Raspberry pie extension board.
NB-IoT and eMTC are emerging IoT communication technologies based on LTE (4G) evolution. They have the advantages of low power consumption, low cost and wide coverage. They are very suitable for applications such as smart meters, remote control, asset tracking, remote monitoring, Internet of Things applications such as telemedicine, mobile POS terminals and shared bicycles. GSM/GPRS and EDGE are traditional 2G and 2.5G communication technologies that support the use of mobile phone cards for texting and wireless communication applications. So whether you want to try new technologies, make evaluations, or want to support multiple ways of communication and positioning, then I am a good choice.
