Loss Prediction Model

Propagation-loss-prediction models play very vital roles in the characterization and design of precise cellular mobile radio communication systems for their specific technical parameters such as transmission power and frequency reuse. This project presents a comprehensive review of the Okumura and Hata propagation-loss-prediction models for heterogeneous terrestrial wireless communication environments. We will conclude by testing the difference in the path loss between predicting values to improve the systems. Our numerical results prove that there occur similar changes with different freq for different distances under identical conditions. The power losses are calculated for various wireless parametric combinations such as the operating frequencies from 150 MHz¿1.9 GHz, and the distances between transceivers from 50¿200m. Other specific parametric combinations such as the electrical-physical-geographical factors, like different height for transceivers and the operating (suburban or urban) zone related issues are also considered. We analyze all the design features, modeling factors and application-issues of the Okumura and Hata models separately keeping the standard assumption.
