Radio propagation path loss prediction of UMTS for an urban area

In this paper, three path loss models were used to predict path loss for the UMTS, in Istanbul, Turkey. Used models are Advanced Okumura-Hata model and Algorithm 9999 from the empirical path loss model class and Advanced Walfisch-Ikegami model from the deterministic path loss model class. The study concentrates on comparative parametric analysis for propagation path loss in macro cell region using different models and contains comparative study with real measurements obtained from a WCDMA based wireless network. This study concluded that among three models, the Advanced Walfisch-Ikegami model gives the best result in the urban environment for Istanbul.
