Nokia and Boldyn Networks Bring Private 5G to Callio Mine

Nokia and Boldyn Networks have deployed a private 5G network at the Callio FutureMINE site in Pyhäjärvi, Finland. The former copper mine, once fully operational for more than 60 years, has been transformed into a testbed where technology companies can trial advanced mining solutions in a real-world underground setting. The deployment provides high-bandwidth, low-latency connectivity across multiple levels and tunnels, some reaching depths of 1.5 kilometers.

The network is designed to support demanding mining applications such as automation, remote vehicle control, real-time visualization, and improved communications. With private 5G in place, operations that once required personnel underground can increasingly be managed from the surface, improving both safety and efficiency. The system also allows for the testing of next-generation equipment in conditions that reflect the challenges faced by active mines, without the risk of disrupting production.

"Mining is one of the toughest environments on earth for connectivity, and private 5G is proving to be a game-changer. Together with Boldyn Networks, we are enabling Callio to demonstrate how secure, reliable, and high-performance networks can transform underground operations —making them safer, more sustainable, and more efficient. This deployment underscores Nokia's leadership in delivering industrial-grade private wireless networks that power the future of critical industries," said Michael Aspinall, Head of Enterprise Campus Edge sales in Europe at Nokia.
