Job duties/accountabilities

5G RF Propagation Modelling Expert - Key Responsibilities

1. RF Network Design & Planning
   • Design and optimize 5G NR (New Radio) RAN (Radio Access Networks), including macro, micro, and small cell deployments.
   • Develop RF coverage, capacity, and quality plans using industry-standard planning tools such as Atoll, Planet, or iBwave.
2. Propagation Modelling & Analysis
   • Create, calibrate, and validate RF propagation models (e.g., COST 231, ITU-R, WINNER II) for various environments (urban, suburban, rural).
   • Use terrain, clutter, and building data along with CW measurement results to enhance model accuracy.
3. CW Data Analysis & Modelling
   • Conduct and analyze CW (Continuous Wave) measurement campaigns to characterize the radio environment.
   • Use CW data to calibrate propagation models, identify RF anomalies, and validate predicted vs. actual signal behaviours.
   • Interpret CW data to derive critical RF parameters such as path loss, signal strength, and propagation constants.
4. Simulation & Optimization
   • Run RF simulations to predict 5G NR performance metrics including RSRP, SINR, and throughput.
   • Leverage drive test data, CW data, and post-processing tools (e.g., TEMS, Nemo, Actix) for model tuning and optimization.
5. Technology Integration
   • Evaluate and plan advanced 5G features including Massive MIMO, beamforming, carrier aggregation, and mmWave integration.
   • Assess propagation characteristics across low-, mid-, and high-band 5G spectrum.
6. Capacity Planning & Performance Analysis
   • Conduct KPI-based network performance analysis to support capacity planning and radio optimization.
   • Forecast traffic growth and recommend enhancements to maintain service quality and user experience.
7. Cross-Functional Collaboration
   • Work closely with RF engineers, field teams, and vendors to implement and validate RF designs and CW measurement plans.
   • Act as a subject matter expert for CW testing, propagation behaviour, and RF environment characterization.
8. Documentation & Reporting
   • Produce detailed RF planning and propagation modelling reports, including CW data analysis outcomes.
   • Present model calibration results and RF planning strategies to stakeholders and project managers.
9. Tool Development & Automation
   • Build or enhance internal tools/scripts for data analysis, model calibration, and RF planning using Python, MATLAB, or similar tools.
10. Regulatory & Standards Compliance
    • Ensure RF designs adhere to regulatory requirements and industry standards (e.g., 3GPP, FCC, CEPT).
    • Support spectrum planning, licensing, and compliance reporting activities.
