Job duties/accountabilities
5G RF Propagation Modelling Expert -- Key Responsibilities
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.
Propagation Modelling \& Analysis
- Create, calibrate, and validate RF propagation models (e.g., COST 231, ITU-R, WINNER II) for a variety of environments (urban, suburban, rural).
- Use terrain, clutter, and building data along with CW measurement results to enhance model accuracy.
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.
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.
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.
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.
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.
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.
Tool Development \& Automation
- Build or enhance internal tools/scripts for data analysis, model calibration, and RF planning using Python, MATLAB, or similar tools.
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.
