Digital twin for RF planning: propagation modeling, coverage prediction, site optimization

Propagation Modeling in the Twin

RF planning twins incorporate sophisticated propagation models calibrated against real-world measurements. Traditional planning tools use generic models like COST-231 or Okumura-Hata with manual tuning. A digital twin continuously recalibrates propagation models using live MDT measurements, adjusting path loss exponents, clutter corrections, and diffraction parameters per cell. This produces propagation predictions accurate within 3-5 dB RMSE compared to 8-12 dB for uncalibrated models. Some twins integrate ray-tracing engines for dense urban areas, computing multipath reflections off…
