our work in hard rock

Hard rock mining is one of the foundations of today’s global economy. Mining natural resources is difficult and hazardous work. Companies must strive to reduce their cost per tonne while still providing a safe and productive working environment.

More and more mines are recognising the role that technology, networking and communication play in mine safety and productivity. The N-CONNEX product line was designed to supply hard rock mines with rugged and cost-effective network infrastructure. N-CONNEX provides a scalable, plug and play network solution that is suitable for your mine from the smallest start-up to the largest operation.

NLT is eager to demonstrate our experience in designing, manufacturing, deploying, and supporting a scalable communication and networking solution that will immediately generate value for your investment – and peace of mind for your miners.

our success in hard rock

NLT Digital Solutions N-Connex product line was made to supply hard rock mines with cost-effective and rugged network infrastructure. N-Connex has provided a network solution that can enable underground IoT around the world in large mines looking for a modular, plug and play solution to reduce downtime and increase safety, security, and productivity.


Distribution Module


The Distribution Module provides connectivity to a one (1) Gigabit Ethernet backbone. The module includes eight (8) managed PoE ports, two (2)  Non-PoE Ports and four (4) Single Mode Fibre Ports to enable a range of solutions and network topologies.

The Distribution Module can actively manage 240W (at 25°C) of total Power over Ethernet (PoE) supply across the various Ethernet ports. This enables a large range of high power consuming PoE devices to be simultaneously connected. 

When combined with the N-Connex Bolt Access Points we can achieve strong and reliable WiFi coverage  in underground mines, tunnels and heavy industrial facilities. NLT’s preterminated, rugged fibre  connects multiple Distribution Modules to form a redundant network topology.

As with all N-Connex modules it is fit-for-purpose and is designed for harsh environments. The module can be mounted on the NLT proprietary quick fit frame or be mounted as a standalone device. The  Distribution Module supports many advanced network standards to optimise network performance, ease maintenance issues and secure network safety.



Communication is critical for improving safety and maximising development rates. Conversing in real time with underground personnel ensures your operations are running efficiently.

NLT’s range of network-based communication products can be used wherever a WiFi signal is present. This eliminates the need for a separate solution for communication and data networking, improving your overall return on investment. The N-CONNEX network solution is able to provide 100% underground WiFi coverage delivering a seamless Communication Solution when combined with digital WiFi radios and the NLT tracking engine.

Our preferred range of radios from iCOM can be handheld or vehicle mounted. They feature push to talk, individual or group talking and an unlimited number of channels. The Digital iCOM radios feature excellent voice quality and can easily integrate with most telephone networks or other communication platforms.

Smart phones, tablets and any WiFi enabled device can be easily integrated into the NLT network opening avenues of operational management that were previously unknown to the sector.

Installing an N-CONNEX network is the answer to maximise efficiency and productivity.
