This article concerns some realistic scenarios for evaluation of the EM field and for better comprehension of its behavior indoors, outdoors and terrain areas having a place nearby of base stations [H. Lehmann et al., 2003]. Based on the method of auxiliary sources the new approaches are presented in case of problems with the electrically large objects using reasonable computational resources and keeping acceptable accuracy [R. Zaridze et al., January 2002]. Three general scenarios are marked. First, the finding of field distribution indoor, without influence of outside objects. Second considers the field distribution near the wall with finite sizes when effect of ground is taken into account. Third is the finding of the field distribution near mountains or hills. These scenarios are an integral part of all cities and consequently are taken for consideration. Corresponding results are presented below.
