DATA VISUALIZATION

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

Traditional cellular network

The growth number forecast of of the IoT connection (Billion)

LPWA connection occupancy

*LPWAN:Low Power Wide Area 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

consumption

Within ST Flexible bandwidth of 3.75kHz and 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.
