NB-IoT series
Designed with the standard NB-IoT protocol, the NH01A is a high-performance, low-power NB-IoT module that supports full-band operation of the network.
The NH01A is suitable for a variety of demanding work environments due to its compact design, low power consumption and good temperature characteristics. It is widely used in M2M IoT, such as smart parking, smart meter reading, smart city, smart security, agriculture and environmental monitoring, etc. It also can build a IoT management system with the smart cloud.
