Abstract

The modified method of loss propagations calculation in large cities M. Wnuk, G. Rozahki, W. Kolosowski Faculty of Electronics Military University of Technology Poland Abstract In our paper the UTD (Uniform Theory of Diffraction) modified method of loss propagation calculation in urban areas is presented. This modified method is concerned with using geometry optic to propagation model and formula application that occur in the UTD method for reflection and diffraction wave coefficients. The superposition method is used to calculate the resultant field. On the basis of the analysis done, the calculation algorithm is proposed. The calculations presented in this paper are hypothetical 1 Introduction In recent years personal communication systems have been dynamically developed. An increase of requirements in the quality of service and scope accompany minimalization of power emissions by radio equipment. This requirement realizes both the cordless telephony and 2G/3G cell telephony systems. Cordl
