BAI Communications highlights successful Finnish deployment as blueprint for Australian mining transformation

The future of underground mining has arrived, and it’s powered by private 5G networks. A groundbreaking deployment at Finland’s Callio Pyhäjärvi mine by our sister company Boldyn Networks and valued partner Nokia demonstrates how dedicated wireless infrastructure is revolutionising operations in some of the world’s most challenging industrial environments.

Mission-critical connectivity below ground

This innovative private 5G solution delivers unprecedented capabilities for underground mining operations:

  • Ultra-reliable connectivity – Seamless communication networks that maintain signal strength and stability across multiple underground levels.
  • Enhanced safety systems – Real-time positioning and digital twin technology that monitors every person, vehicle, and piece of equipment underground, with instant evacuation alerts and safety zone routing when GPS is unavailable.
  • Operational excellence – Tele-remote vehicle operation and autonomous machinery control from the surface, eliminating downtime while maximising equipment utilisation and reducing the need for personnel in hazardous conditions.
  • Industry 4.0 ready – Ultra-low latency networks supporting next-generation mining applications including 3D mapping, real-time operational control, and integrated automation systems that enable up to 90% of underground workers to operate from the surface.

Australia’s mining sector: ready for digital transformation

Australia’s mining industry, generating over $400 billion in export revenue annually, stands at the forefront of a technological revolution. As operators of extensive underground mining operations across gold, copper, iron ore, and coal extraction, Australian companies are uniquely positioned to leverage private 5G technology’s transformative potential.

The success at Callio Pyhäjärvi mine demonstrates that private 5G networks can deliver mission-critical connectivity where traditional infrastructure fails. This 1.5-kilometre-deep former copper mine, operational for over 60 years, now serves as Europe’s premier testing ground for next-generation mining technology. For Australian mining companies seeking competitive advantage through operational excellence, this real-world validation represents compelling evidence of private 5G’s transformative potential.

Proven results from extreme conditions

The Callio deployment showcases private 5G’s capability to overcome underground mining’s most challenging connectivity obstacles: extreme depth, complex tunnel networks, harsh environmental conditions, and constant movement of personnel and machinery. Using Nokia’s Modular Private Wireless technology, the network delivers seamless coverage across multiple levels and tunnel networks stretching several kilometres.

Building tomorrow’s connected mining infrastructure

At BAI Communications, we understand that private 5G networks address the unique challenges of underground mining environments where traditional connectivity solutions cannot deliver the increased throughput required for critical operations and advanced applications. The Callio deployment demonstrates that in mining environments, connectivity is mission-critical, delivering real-time data and ultra-low latency to ensure every person and asset remains visible and protected while minimising costly downtime and reducing manual process risks.

The Callio deployment demonstrates measurable operational improvements across three critical areas:

  1. Advanced communication systems – High Throughput, Low-Latency Wireless Data Communications, coupled with integrated Mission Critical Voice Services across a single platform.
  2. Autonomous operations – Enabling remote operation of vehicles and machinery from the surface, with technology companies like world-leading manufacturer Normet successfully testing autonomous underground vehicles.
  3. Digital Twin technology – Supporting integrated 3D mapping and real-time positioning systems that create comprehensive operational visibility, allowing teams to monitor personnel, vehicles, and equipment locations instantly. The collaboration between our sister company Boldyn Networks and Nokia exemplifies how strategic partnerships drive innovation across mission-critical industries, with private 5G technology proving transformational in underground operations by making them safer, more sustainable, and more efficient.

Strategic imperative for Australian mining leaders

Australian mining companies have the opportunity to establish global leadership in connected, automatous underground operations. The proven success at Callio Pyhäjärvi mine validates that private 5G technology delivers measurable operational improvements today, with real-world testing demonstrating the potential for up to 90% of underground workers to operate safely from the surface.

Technical challenges increase significantly as mining operations extend to greater depths. The safest and most efficient operational strategy involves removing personnel from hazardous environments and enabling comprehensive remote operation capabilities. A fully automated mining future could see the vast majority of underground workers operating from surface facilities, but this transformation requires dedicated 5G networks.

This transformation addresses a fundamental industry reality: traditional connectivity solutions simply cannot meet the demands of modern mining operations. As the global mining industry increasingly adopts digital transformation strategies, early adopters will secure competitive advantages in safety performance, operational efficiency, and cost management that define sustainable competitive advantage.
