Radio propagation model for mobile network planning in the C-band

• Radiowave propagation modelling improvement by nonlinear regression algorithms. • The IMT 5G/6G C-band radiowave propagation model based on real world measurement data. • Better IMT 5G/6G network planning in the C-band thanks to the improved radiowave propagation model. This paper proposes an enhanced radio propagation model derived from a tuned Standard Propagation Model (SPM) for efficient and optimal network planning of International Mobile Telecommunications (IMT) systems (like 5G and 6G) in the C-band (frequency range 3400–4200 MHz) for typical European cities. Based on a measurement campaign conducted by the authors, the model was analyzed and subsequently tuned using nonlinear regression, yielding results that more accurately estimate coverage areas compared to the standard. Error analysis demonstrated significant improvements in propagation modeling, resulting in reduced deviations between simulations and measurements.
