Some experimental investigations in the WiMAX band and comparison of propagation models in mixed urban environments of Western India

This paper presents the analysis of measurements taken at 2.3?GHz in the mixed urban environments of Western India for 17 WiMAX base stations. Coverage predictions using various models and their comparison with observed data have been carried out. Measured path loss is compared with the theoretical path loss values estimated by COST-231 Hata model, the SUI model, the ECC model, and ITU-R (P.1411-1) model. This investigation is essential to provide last mile broadband wireless access, before deploying WiMAX. Path loss exponents, mean errors, and standard deviations of all the prediction methods were deduced and suitable models for path loss prediction methods were identified.
