Comparison of Measurement Based and Site Specific Ray Based Microcellular Path Loss Predictions

Abstract

The performance of site specific ray tracing methods based on UTD to predict the path loss are compared against measurement based models and measurements. An empirical formulation based on a simple least squares regression At from one site is used as a prediction tool at another site having similar building environment. Comparing the accuracy of both types of prediction models, it is found that the site specific method provides an improvement over the traditional method of measurement based path loss prediction.
