Welcome to Industry 4.0 with 5G Steel


Two people on a construction site look at a digital work tablet.

In 2021, the leading French steelmaker ArcelorMittal launched 5G Steel, the largest 4G/5G network in an industrial environment. Backed by Orange Business and Ericsson, and supported by the French government as part of the France Relance recovery plan, this project has been operational since February 2023. Our experts were involved in 5G infrastructure integration and system integration, from needs analysis to the implementation of use cases with the teams. 

5G Steel responds to industrial challenges by offering extensive mobile coverage across all sites (including metal architecture), high speed, low latency, network slicing to offer a level of service tailored to each operational process requirement, and data security. 

Operators can now take readings on tablets and share data more quickly. Information relating to the steel to be recycled is exchanged automatically between the various parties involved. Other industrial use cases will be deployed, such as the widespread roll-out of mobile maintenance with field data feedback, virtual or augmented reality, and safety devices. 

With 5G Steel, ArcelorMittal is poised to transform itself and succeed in the major transitions involved in the decarbonization and digitizalation of steel industry processes and procedures. These changes are essential if the Group is to maintain its leadership position and confront intense international competition, amplified by today’s energy challenges.
