Tait DMR Tier 3 Trunked Network Solutions for Mining

• True trunking intelligence: automatic channel allocation, voice/data prioritisation and fleet numbering that simplifies communications for hundreds of users. DMR Tier-3 adds network intelligence not available in conventional Tier-2 systems, improving capacity and reliability for large mining fleets.

• Scalable for growth: multi-site, multi-channel node architecture that scales from a single site to regional networks. The Tait TN9300 node controller is purpose-built for Tier-3 mission-critical deployments.

• Enterprise features for safety & efficiency: AVL, automated geofencing alerts, dispatch integration, media recording and fleet management for real-time operational control.

What MiningTelecoms delivers:

• System design & RF planning — coverage modelling for open-pit, underground, haul roads and camp networks.

• Tier-2 → Tier-3 migration planning — phased or big-bang cutovers, compatibility checks and cutover risk mitigation. We plan frequency, licensing, training and cutover milestones. (We’ve delivered independent technical reviews and upgrade plans for Tier-2 → Tier-3 projects.)

• Core network deployment — node controllers (Tait TN9300), inter-site IP backbone, GPS timing, dispatch & analytics servers. TN9300 supports hosted or server installations for flexible architectures.

• RF sites & simulcast — single channel base stations or simulcast site groups for continuous coverage across large pits and corridors.

• Integration & interoperability — gateways to bridge analog/MPT/DMR Tier-2 radios during migration and IP/telephony/dispatch integration. Tait and other manufacturers support re-use of RF site equipment (antenna combiners) and network gateways to ease migration.

• Testing, training & O&M — site acceptance testing, dispatcher/radio user training and support packages

• Simulcast & high-availability for continuous mission-critical coverage.

• Secure communications — digital voice/data encryption and AAA for access control.

• AVL & geofencing — vehicle location, automated alerts and safety integration.

• Over-the-air programming & remote management — centrally manage hundreds of radios and push updates remotely.

• Standards-based interoperability — DMR IOP-compliant nodes and terminals for multi-vendor fleets.

• Optimised IP backbone — recommended minimum linking bandwidth and jitter planning; Tait guidance shows minimum link bandwidth planning (e.g., ~600 kb/s per site for multi-channel situations).

We specialise in mining migrations with minimal operational disruption:

• Dual-mode radios & phased migration: many radios are software-upgradeable (DMR Tier-2 ↔ Tier-3) or can run quad-mode (Analog/MPT/DMR Tier-2/Tier-3). This lets us phase the transition while keeping legacy systems operational.

• Reuse where possible: antenna combiners, site shelters and some RF hardware can be reused; gateways allow mixed-vendor interoperability during cutover.

• Proven cutover strategies: we develop site-by-site cutover plans (big-bang or phased), operator training and contingency plans so safety-critical comms remain uninterrupted. (See our project work and independent reviews.)
