Nokia and Boldyn deploy private 5G at Finnish mine testbed

Nokia and Boldyn deploy private 5G at Finnish mine testbed is profiled by BTW Media because public-source evidence links it to internet infrastructure, governance, operational dependencies, or market visibility.

• Nokia and Boldyn Networks launch private 5G network across underground tunnels in one of Europe’s deepest mines.
• Use cases include remote machinery, real-time digital twins, and replacing walkie-talkies for more reliable worker communication.

What happened: Nokia and Boldyn build private 5G testbed at Finnish mine to support automation and worker safety

Nokia and Boldyn Networks have deployed a private 5G network at the Callio FutureMINE site in Pyhäjärvi, Finland, using Nokia’s Modular Private Wireless (MPW) to cover multiple underground levels and extensive tunnel systems—some up to 1.5 kilometres deep. The network enables remote operation of vehicles and machinery from the surface, reducing hazards for workers underground. It also replaces traditional walkie-talkie systems so workers can communicate clearly across all levels and supports real-time 3D mapping and digital twin technologies for monitoring vehicles, personnel, and equipment.

Other participants include Normet testing autonomous equipment, and software firm Cybercube delivering visualization and positioning services. According to Nokia, the site is being transformed into a full testbed where next-generation automation and safety solutions are validated under difficult conditions.

Why it is important

This deployment highlights how private 5G networks are becoming essential in industries with harsh, remote, or safety-critical environments. Mines are among the toughest environments for connectivity due to depth, confined tunnels, dust, and machinery; solutions that deliver ultra-low latency and high bandwidth in such settings are rare but increasingly demanded. The work at Callio FutureMINE demonstrates that underground mining operations can gain operational efficiency and improved safety, aligning with global industry standards on digitalisation and automation.

From a technology-governance perspective, this case sets a precedent for how public safety, worker welfare, and productivity can be improved via cutting-edge wireless infrastructure. It may accelerate regulatory and investment attention to private network deployments in mining, transportation, and logistics sectors. For companies designing tools and equipment, knowing there is reliable connectivity underground unlocks new use cases, business models, and R&D opportunities. However, long-term impact will depend on maintaining reliability, ensuring security, and supporting scalability in energy, maintenance, and regulatory compliance.
