Abstract

Accurate modeling of wireless signal propagation in complex environments is essential for the efficient planning of next-generation communication networks. This study investigates the impact of transmitter placement and elevation on signal coverage and interference levels within a structured campus environment. Using Sionna ray tracing, a differentiable and GPU-accelerated ray tracing framework, realistic 3D models of the Aydin Adnan Menderes University main campus were constructed and simulated. Three transmitter deployment scenarios—distributed, centralized, and optimized—were evaluated in terms of path gain, Received Signal Strength (RSS), and Signal-to-Interference-plus-Noise Ratio (SINR). The simulation results reveal how different spatial configurations influence signal propagation, coverage uniformity, and interference. The findings provide valuable insights into strategic transmitter placement for enhanced network performance in real-world deployments.
