Digging into Connectivity in Mining Environments: In-tunnel

June 1, 2024



The connectivity challenge is further compounded by the differing technologies needed at each level of the mine to ensure optimum coverage; surface-level infrastructure uses a completely different setup than deep underground, where new tunnels are being created. 

In this blog, we will explore the connectivity needed for an established, active tunnel. How do we deliver the setup needed to support mission-critical communications and meet the performance and regulatory requirements of mine operators? Leon Lenze, Product Line Manager – Cables at RFS explains.

The Challenge:

The unique underground environment of mines presents a unique set of challenges for delivering connectivity. Tunnels, shafts, and the presence of heavy machinery and rock formations require specialized solutions to offer seamless communication and data transfer. Traditionally, mine operators have taken the approach of using antennas and repeaters. However, this requires a high volume of equipment to ensure complete coverage in hard-to-reach and obstructed areas. 

The Technology:

At RFS, we advocate a different set-up. Our customers use a passive distributed Antenna Solution (DAS) with radiating cables that work like antennas in long mining tunnels for mission-critical and 5G transmission. There are several key advantages this offers.


Crossover is more than a distribution partner for many of the world's top wireless broadband and in-building wireless/distributed antenna systems (DAS) manufacturers. Crossover is more than an engineering firm, with world class engineers, utilizing powerful software tools like Pathloss and iBwave. We are your "5G Wireless Technology Partner" for solutions that just work. Crossover was founded in 2007 by a group of industry veterans, looking to bring a new approach to how wireless solutions are sold and supported in the North American market. Focused on Best of Class wireless solutions, Crossover provides skilled design and implementation engineering expertise with every product sold to ensure your network build is a success.
