NB IoT
Compatible with the following Weidos PLC models:
-
WEIDOS-MKR1010-NBIOT-A1
-
WEIDOS-ESP32-NBIOT-A1
Allows LTE Cat NB1 connectivity based on the SARA-R412M, a specialized multi-band IoT module with very
low power requirements, making it perfectly suited for various IoT-based applications. Ensures data integrity
between applications via secure communication protocols, notably including two-way authentication
between the client and server. Its most important advantage is the ability to use already widely established
cellular network infrastructures. These features make the NB IoT click a perfect choice for a wide range of
IoT applications such as smart metering, bike sharing, smart parking, smart city, security and asset tracking,
home appliances, agricultural and environmental monitoring, and more.
Type
