Case Study – Greek Gold Mines: Flexible, Long-Life, Mission-Critical Connectivity

April 1, 2025

Infrastructure

The Challenges

As the latest project builds upon RFS’s existing relationship with the mine operator, and RFS has extensive experience deploying communication infrastructure in mining environments, identifying the challenges was a straightforward process:

Challenging Underground Conditions

Mines require durable cabling capable of withstanding harsh conditions while ensuring reliable signal transmission. Traditionally, this would be achieved with antennas and repeaters. However, RFS advocates a cable-based approach as a more streamlined and effective solution.

Mission-Critical Capabilities

The infrastructure needed to support mission-critical frequencies of 400MHz.

Scalability

As the mines expand, cabling solutions must support both current and future operational needs.

Regulatory Considerations

Greece does not mandate specific cable classifications for mining environments. Therefore, RFS needed to advise the mine operator on how to best balance safety, cost, and optimum performance
