Abstract

Calculation of level of losses of a radio signal of cellular communication in the conditions of a city with dense many-storeyed building on the basis of statistical models is resulted. On the basis of statistical look-ahead estimations of loss of capacity of a signal on an input of user's stations scientific directions of perfection of parameters of cellular communication can be developed.
