Theoretical Prediction of Propagation Over Buildings for Low Base Station Antennasd diffraction past rows of buildings. The solution for this diffraction problem for sources near to or below the rooftops gives the dependence of the range index on antenna height and base station height gain, which are in agreement with measurements.
