The aim is to develop an accurate channel modeling approach for mmWave communication in indoor smart environments.
Utilized ray tracing techniques to model mmWave signal behavior in complex indoor settings.
Simulated interactions of signals with environmental elements using 3D building models.
Captured parameters like path loss, delay spread, and angular spread to analyze performance.
Demonstrated higher path losses for mmWave frequencies compared to sub-6 GHz bands.
Identified significant influence of shadowing and blockage on mmWave signal propagation.
Validated the ray tracing model against empirical data, confirming its accuracy for system design.
