About the role

The LTE RAN RF Planning Engineer is reliable for monitoring, optimising, and maintaining the RF performance of a private LTE network and associated wireless technologies used to help mission critical mining operations. This includes ensuring consistent coverage, mobility, and capacity for self-governing haulage, fleet communications, IoT sensors, control systems, CCTV, rail operations, and Cambium point to multipoint (PTMP) / point to point (PTP) wireless links distributed across the mine.
The role focuses on operational RF optimisation, performance troubleshooting, and helping deployment or relocation of LTE cells and Cambium nodes in dynamic mining environments.

What you’ll be doing

• Manage incidents and requests while maintaining high ticket quality and hygiene.
• Develop RF propagation and coverage models for open-pit mine environments using tools such as HTZ, Atoll, Mentum, or similar.
• Perform advanced root cause analysis for LTE outages.
• Maintain and manage LTE macro/small cell hardware (FDD) suitable for dynamic mining operations.
• Perform frequency optimization, PCI/RSI planning, link budgets, interference analysis, and EARFCN/channel allocation.
• Create RAN capacity plans aligned with AHS (Autonomous Haulage System), telemetry, CCTV, and IoT demands.
• Provide remote guidance to field teams performing RF surveys, antenna alignment, and LTE trailer moves.
• Use TEMS Pocket / TEMS Discovery for drive test data analysis (onsite teams), RSRP/SINR profiling, Layer 3 message decoding, handover investigations, and KPI trend analysis.• Analyse LTE RAN performance KPIs including throughput, PRB utilisation, accessibility, retainability, and mobility metrics.• Identify and resolve issues such as overshooting, coverage holes, interference, and imbalance.• Produce optimisation recommendations such as power adjustments, tilt optimisations, parameter changes, and azimuth• Conduct remote troubleshooting sessions with onsite teams, providing step by step diagnostic guidance.• Manage and optimise Cambium PTP/PTMP backhaul links using tools such as Cambium HTZ/ LINKPlanner.• Perform path profile studies, Fresnel zone checks, and availability modelling.• Provide remote alignment assistance and configuration guidance to site teams.• Work with Mining Technology, AHS, Fleet Management, and OT Automation teams to understand coverage/performance needs, adjust designs for pit progression and mine expansion, and ensure stable connectivity for trucks, drills, shovels, LV, and IoT devices• Provide remote RF design updates as mine topology changes• Provide remote RF design updates as mine topology changes.• Prepare RF design documents, coverage heatmaps, network design packs, BOMs, and commissioning documentation.• Support acceptance and integration testing remotely.• Maintain version-controlled RF documents and change logs.• Design LTE and wireless systems for high reliability in remote industrial environments.• Ensure designs comply with mining standards, cybersecurity requirements, and operational safety guidelines.• Consider resilience, redundancy, and harsh environmental factors when developing plans.• Manage and upkeep of NetAct server and software.
