Estimation of Electromagnetic Background Intensity Created by GSM Cellular Networks Base Stations with High Spatial Density on Urban Area

Abstract

Estimation of the total intensity of electromagnetic background created by GSM-1800 cellular network base stations with spatial density of 3-9 base stations per square kilometer taking into account intrasystem electromagnetic compatibility of the cellular network (levels of intranetwork interference) was executed based on computer modeling of functioning of the cellular network fragment with the use of X3D three-dimensional model of radio wave propagation and three-dimensional model of the fragment of urban area of Minsk. The results are presented for base stations antenna height of 25-35 m, equivalent isotropic radiated power of 33-58 dBm per frequency channel, and for various spatial population density of 6000-12000 people per square kilometer.
