Description
NarrowBand – Internet of Things
(NB-IoT)
The NarrowBand-Internet of Things (NB-IoT) is a technology that follows a set of standards and is designed to facilitate a variety of new IoT devices and services.
It is classified as a low power wide area (LPWA) technology that significantly enhances the power consumption of user devices, system capacity, and spectrum efficiency. It is especially useful for providing reliable coverage in areas with weak signals.
Designed to Use in Harsh Environments
-40℃ ~ 85℃ operating temperature and IP68-rated enclosure, suitable for outdoor use, high UV exposure, heavy rain, dusty conditions, etc.
