Description

Unit NBIoT-CN is a NB-IoT wireless communication module designed for the Chinese region Cat-NB frequency band. It features the SIM7020C communication module, uses serial communication (controlled by AT commands), and integrates an SMA external antenna interface to enhance communication quality and signal stability. The SIM7020C module is an optimal solution for low-latency, low-throughput applications, making it highly suitable for IoT applications such as metering, remote control, asset tracking, remote monitoring, telemedicine, and shared bicycles.
