THEORETICAL PREDICTION OF MEAN FIELD-STRENGTH FOR URBAN MOBILE RADIO

Based on the analysis of physical multipath propagation structure in urban areas, ray-theoretical waves are shown to make a major contribution to a mean field strength on a street in a moderate city. A computer-aided prediction system has been developed, which calculates a mean field strength around an arbitrary receiving point on the ray-theoretical basis when building data are given. The predicted values are compared with the measured in appreciable agreement, suggesting the possibility of purely theoretical prediction.
