Path Loss Prediction Applying Empirical Model in Civil Buildings with External Trees

This study investigated the method to apply influence of trees, which are external factors, as a generalized path loss model in simulation ray tracing-based electromagnetic analysis inside building by waves. The tracing and model, wave models used this study, were described, frequencies ranging from 0.6 GHz 6 for simulation. target was performed using Wireless Insite, commercially available tool based on tracing, applied considering size location trees affecting experiment experimental environment. Finally, accuracy confirmed comparing result value with obtained through actual experiments.
