Comparative Analysis of Propagation Path loss Models with Field Measured Data

Abstract –The propagation path loss models may give different results if they are used in different environment other than in which they were designed. In this paper we compare the different path loss propagation models with measured field data. For comparative analysis we use the log distance path loss model, Stanford University Interim (SUI) Model, Hata model, Okumura’s Model, COST231 Extension to Hata Model and ECC-33 model along with the field measured data. The field measurement data is taken in urban(high density region), sub urban(medium density region) and rural(low density region) environments in INDIA at 900 MHz &1800 MHz frequency with the help of spectrum analyzer. After analyzing the results COST-231 and SUI Model shows the better results in all the three environments particularly in urban and sub urban environments.
