Accelerating Productivity and Safety
Mining communications systems combine digital radio infrastructure, network coverage design, and mission-critical communications technologies to support safe and efficient mine operations. The sections below outline the key communications systems used across modern Australian mining operations.
Mining Communications Systems Technologies
Digital Radio Networks for Mining
Digital trunked radio systems are the backbone of communications infrastructure across modern mine sites. These networks support voice, telemetry and safety communications across large open-pit and underground operations.
MiningTelecoms designs and deploys digital radio networks using technologies including DMR Tier III, MOTOTRBO Capacity Max and P25 trunked systems.
Motorola Capacity Max (Tier III)
Capacity Max is Motorola’s advanced DMR Tier III trunked system built for industrial and mining environments where fast roaming, strong redundancy and large-scale expansion are required. It supports large talkgroup management and is ideal for multi-site mine operations and contractor-heavy environments.

Tait DMR Tier III Trunked Radio Networks
DMR Tier III trunking is designed for high-user environments where multiple crews need reliable coverage, fast call setup and scalable channel management. These systems are ideal for expanding mining operations that require controlled talkgroups, site-wide dispatching and efficient channel allocation.

Radio Coverage Design & Site Communications Planning
A mining communications system is only as strong as its coverage design. We provide mine site radio surveys, RF planning, repeater placement strategy, and ongoing optimisation to ensure crews remain connected across high-risk and geographically complex environments — including pits, infrastructure corridors and underground.
This includes:
-
site coverage audits
-
antenna and repeater design
-
terrain modelling
-
high-risk zone assessments
-
upgrade planning for growth phases
P25 Phase 1 & Phase 2 Trunked Networks
P25 systems are widely used for mission-critical communications where security, interoperability and reliability are paramount. P25 Phase 2 provides increased spectral efficiency while supporting critical voice communications, emergency response and integration with existing infrastructure.

-
dispatch consoles
-
emergency systems
-
monitoring systems
-
interoperability gateways

Mining Communications Systems – Frequently Asked Questions
What is a mining communications system?
A mining communications system is the combination of radio infrastructure, network coverage design, devices and software used to keep mine site personnel connected. This can include Private LTE networks, DMR Tier III trunked radio systems, P25 trunked networks, repeaters, base stations, dispatch consoles and intrinsically safe radios for hazardous environments.
What is the best radio communication system for a mine site?
The best system depends on the mine size, terrain, hazards, number of users and whether voice-only or voice + data is required. Many mining operations use DMR Tier III trunked radio or P25 systems for mission-critical voice, and Private LTE for high-capacity data, IoT, telemetry and modern digital mining operations.
What is Private LTE and why is it used in mining?
Private LTE is a dedicated 4G/5G mobile network deployed on-site to provide secure voice and data communications across a mine. It is used for mine-wide connectivity, telemetry, IoT devices, CCTV/video, fleet monitoring, push-to-talk services and connecting remote infrastructure. Private LTE networks are designed for reliability and control in environments where public networks are limited or unavailable.
What is DMR Tier III trunked radio and how does it work?
DMR Tier III is a digital trunked radio standard designed for large, high-user environments. It automatically allocates channels for talkgroups, improves spectrum efficiency, supports roaming across sites, enables dispatching and scales efficiently. It is widely used in mining where multiple crews need reliable coverage and controlled communications across a large footprint.
What is the difference between P25 Phase 1 and Phase 2?
P25 Phase 1 uses FDMA (one voice call per channel) while Phase 2 uses TDMA (two voice calls per channel), effectively doubling capacity and improving spectrum efficiency. Both are designed for mission-critical communications and are often used where interoperability, security and reliability are required.
How do you design radio coverage for a mine site?
Coverage design typically includes an RF site survey, terrain modelling, repeater/base station planning, antenna design, and testing across operational zones. Mine sites often require careful planning for pits, haul roads, underground areas and remote infrastructure. Ongoing optimisation ensures reliable communications as operations expand.
Do mine sites require intrinsically safe communications equipment?
Yes — many mine sites (particularly gas, coal and hazardous areas) require intrinsically safe (IS/Ex) radios and accessories that meet strict safety standards. Intrinsically safe equipment reduces ignition risk and is essential for compliance in explosive or high-risk environments.
Can MiningTelecoms support mine sites Australia-wide?
Yes. MiningTelecoms supplies, deploys and supports mining communications systems across Australia, including remote and regional mine sites. We provide system design, installation, programming, coverage audits, ongoing maintenance and upgrade planning for long-term operational reliability.
