Enabling a Wide Range of NB-IoT Applications with OpenCPU

Overview

Narrowband Internet of Things (NB-IoT) is a low-power wide-area network (LPWAN) technology based on cellular communication. Featuring ultra-low-power consumption, wide-range coverage, high-capacity connectivity and high security, it is a significant part of future-oriented 5G standard systems. Backed by a wide range of platform solutions with uncompromised security, NB-IoT is enabling billions of connections among thousands of applications. Featuring secure and ultra-low-power OpenCPU, our industry-leading NB-IoT System-on-Chip (SoC) GR851x series stands out with competitive and cost-effective single-chip solutions for applications in smart meters, asset management, smoke detectors, smart bands, and other NB-IoT applications.
