Don't be confused！Let us guide you to understand the
Industrial Internet and Industry 4.0
With the emergence and popularization of the concepts of Industrial Internet and
Industry 4.0, more and more people recognize these two words but often confuse them.
Aren't they all proposed for intelligent manufacturing? Isn't it just the people who
proposed it are different? Is there any difference? Today, let the editor take you to know
more about the Industrial Internet and Industry 4.0 and how technologies such as the
Internet of Things, 5G, Big Data Analysis, and Machine Learning help the construction
and development of the two.
Industrial Internet
In 2012, General Electric formally proposed the concept of the Industrial Internet. It refers
to integrating complex physical equipment with the network, using the obtained data and
information to control and adjust the equipment, optimize the process, and build an
integrated industrial system.

The Industrial Internet does not simply replicate the Internet of Things, but
integrates various acquisition and control sensors into the production process,
collects data in an all-around way, turns each process and equipment into a data
terminal, and conducts data analysis and mining. It not only realizes the connection
between things but also the comprehensive interconnection of people, machines, and
things in the industrial field.
It is difficult for traditional industrial wireless networks to meet the requirements of
industrial Internet with large broadband, wide connections, and real-time scenarios.
For example, the WiFi network used for AGV scheduling communication has small
coverage and unstable performance, and there are security risks. The 5G network
itself has the characteristics of large bandwidth, wide connection, and low latency,
making it the best option for wireless networks to support industrial upgrades.

5G FWA is Fixed Wireless Access. Sun Telecom, which provides "systematic, end-to-
end, one-stop"fiber optic total solutions and products for worldwide customers,
believes that: FWA (Fiber+5G) is the most desirable use case for 5G.
5G FWA uses electromagnetic waves instead of cables as the signal transmission
medium, avoiding the problems of trenching and wiring in traditional deployment
methods. These provide more cost-effective and innovative services that enable
factories and users in remote areas to use the high-speed real-time network. 5G will
become the central nervous system of the factory in the future, bringing disruptive
changes to industrial production.
Industry 4.0
Industry 4.0 was formally proposed in Germany in 2013. It is the fourth industrial
revolution led by intelligent manufacturing. It makes full use of the combination of
information communication technology and cyberspace virtual system to make the
manufacturing industry intelligent.
Industry 4.0 focuses more on manufacturing and production, using big data analysis,
machine learning, cyber-physical systems, etc. to run through the entire industrial chain to
build flexible smart factories. Industrial development has led to the emergence of typical
database software systems that cannot handle huge data streams. Big data analysis has
become the basis for the digitization of various businesses. It collects, transmits, analyzes,
and uses large amounts of real-time data while generating information to improve
intelligent processes. Ensure efficient and trouble-free execution of industrial production.

However, there are still issues of volatility, uncertainty, complexity, and ambiguity in the
process of Industry 4.0, which affect the process of industrial development and need to be
reasonably resolved. As a branch of artificial intelligence, machine learning can allow
smart devices to learn and make decisions without manual programming through data
collection and processing, model building and training, and adjustment of algorithms so
as to automatically perform tasks.
Summary
The Industrial Internet or Industry 4.0 are all efforts to step into intelligent
manufacturing. In this era of rapid technological progress, enterprises need to choose
their technologies and methods to promote the development of the manufacturing
economy.
