ArcelorMittal France announced the operational launch of 5G Steel, claimed to be the largest 4G/5G 
network in the industrial environment. The initiative, supported by the French government as part of the France Relance economy revival plan, is now enabling the first industrial use cases to be implemented at the ArcelorMittal site in Dunkerque.
The industrial use cases of 5G Steel include:
- The connected operator: The mobility of people and processes enabled by 5G Steel is transforming the way people work in industrial environments. For example, on the hot strip rolling mill, data collection, entry, and sharing operations can be done more quickly and intuitively, as well as inspections during maintenance operations, safety audits, lockout/tagout procedures, and other functions.
- Steel recycling: ArcelorMittal's recycled steel yard management is facilitated by the extensive coverage and high throughput. Steel arriving at the site for recycling is weighed and scanned to assess its density and composition. This data is then automatically transmitted by the operators in charge of quality control from the field via 5G Steel. Machinery operators (crane and stackers) receive the information directly from the production program and can inform about the actions taken through 5G Steel.
Future industrial use cases to be developed on ArcelorMittal's sites include other mobility initiatives in terms of people in work situations, autonomous rail vehicles in Dunkerque and Florange, autonomous road vehicles, the generalization of mobile maintenance with field information feedback, virtual or augmented reality, and safety devices.
5G Steel's capabilities meet the challenges of tomorrow's industry thanks to:
- Extensive coverage: the mobile network covers all ArcelorMittal's complex industrial sites, outdoors and indoors, including underneath high-rise metal structures. This coverage provides greater freedom of movement for operators and connectivity anywhere in the company.
- High speed in response to the high throughput needs of modeled processes, connected objects, production data, etc.
- Low latency: reduced latency supports the deployment of autonomous vehicles and remote-control cockpits, as well as security in high-risk areas
- Network slicing to offer a level of service adapted to each of the needs of the operational processes
- Data security: the private mobile network protects sensitive industrial data
The objective of deploying 5G Steel is also to enable development of the French ecosystem around the value chain of these industrial use cases. 5G Steel will cover the main seaport of Dunkerque and ArcelorMittal's Digital Labs in Dunkerque and Florange, and tests are being carried out to extend the network to the Hauts-de-France and Grand Est regions.
