INTRODUCTION 1 • What is NB-IOT? • Why we choose NB-IOT? HARDWARE & OCEANCONNECT 2 • Hardware devices. • OceanConnect platform. DATA VISUALIZATION 3 • Visualization on platform. • Visualization on app.

What's NB-IOT? A burgeoning standard of IOT The first step in the evolution of the cellular IOT Some pictures in the slide are quoted from HUAWEI HCDA-IoT training materials.

Present situation and the future The growth number forecast of of the IoT connection LPWA connection occupancy (Billion) *LPWAN:Low Power Wide Area Network Traditional cellular network In M2M connection scenarios, the short range commucation still dominates the game. But: • Among them, the number of LPWA connections began to grow rapidly in 2016 , and will exceeded the traditional cellular network in 2019 , about 1.4 billion . • LPWA technolo will have 11% application occupancy in 2024 .

How does it work? ��������������������� ����

How does it work? �.���������������.��� ������������-� ����������� Single-Tone: • Enables extreme low cost loT terminals to compete with non-cellular devices and enable faster time to market. • Not only cellular industry, low cost chip vendors are interested in building ST only chips. Multi-Tone: • Provides higher data rate and can target to replace most of the original CDMA/GPRS IoT applications • Chipset and module has higher cost and power Within ST Flexible bandwidth of 3.75kHz and consumption 15kHz adaptive to different scenarios

Why NB-IOT? Advantages of Low power consumption & Wide coverage Several NB-IOT applications have already been officially launched . In 2020, the NB-IOT network will be nationwide with more than 1.5 million base stations.
