Unit NBIoT
Description
Unit NBIoT is a NB-IoT wireless communication module suitable for global Cat-NB frequency bands. It comes with a built-in SIM7020G communication module, uses serial communication (controlled by AT commands), and integrates an SMA external antenna interface to enhance communication quality and signal stability. The SIM7020G 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.
