Abstract
Radio wave propagation in hilly terrains presents unique challenges due to complex topography, multipath effects, and environmental factors. Accurate prediction of path loss is critical for the design and optimization of wireless communication systems, particularly in fixed wireless access networks. This study analyzes empirical models for radio frequency propagation in hilly regions, evaluating their performance, limitations, and applicability. The investigation synthesizes findings from prior empirical studies (Abhayawardhana et al., 2005; Hata, 1980; Okumura et al., 1968) and evaluates their predictive accuracy in topographically varied environments. A comparative framework is proposed to model path loss, incorporating terrain parameters, antenna heights, and frequency-dependent effects. Results highlight the strengths and limitations of traditional empirical approaches and suggest directions for optimizing RF system deployment in hilly areas.
