NB-IoT Shield 95G with Quectel BC95-G
Narrowband IoT (NB‑IoT), also known as LTE Cat NB1, is a standards-based Low Power Wide Area (LPWA) technology that works virtually anywhere. It simply and efficiently connects devices on already established mobile networks, and securely and reliably handles small amounts of fairly infrequent two‑way data. It provides very low power consumption, excellent extended range in buildings, easy deployment into existing cellular network architecture, network security & reliability and lower component cost.
NB-IoT Shield is an expansion board for Arduino to add NB-IoT technology.
This shield uses Quectel BC95-G. This module supports B1/B3/B8/B5/B20/B28.
NB-IoT and LTE-M are very new services. Ask your mobile operator about availability of SIM cards, coverage, frequencies used and login procedures before you buy the shield. See for example Deutsche Telekom IoT.
An antenna is included.
