PULL WAVE MODELING OF WAVE-PROPAGATION IN RADIO-COMMUNICATION SYSTEMS

An efficient planning of radio communication systems, line-of-sight ra dio links as well as cellular radio systems, needs powerful methods fo r modelling electromagnetic wave propagation. Semi-empirical and ray-o ptical wave propagation models do not totally meet all requirements. T herefore full wave models based on the very efficient Parabolic Equati on Method are described. For tile first time they are applied to the w ave propagation modelling in large areas. A comparison of calculated a nd measured path loss values in a wide frequency band demonstrates the ir superior properties. Therefore these models are best suited for cal culations in critical rural environments or for a verification and an improvement of simple wave propagation models.
