A recursive method for street microcell path loss calculations

Abstract

A recursive, reciprocal, very simple and computer efficient mathematical method for microcell path loss calculations is suggested. Arbitrary street crossing angles, bent streets with linear sections and transmitter locations close to the street crossing can be modelled. The method is reciprocal, very computer efficient and simple to use. First, some basic information is given regarding street orientation and transmitter location. Then, the basic model and a simplified version are given, followed by some examples concerning different street crossing angles, which show how the model can handle these cases by choosing appropriate parameter values. Thereafter, two methods are suggested on how to model the well-known dual slope behaviour in microcells. Finally, a simple extension is given by introducing an additional parameter which increases the possibilities to vary the model.
