|Abstract:||Results of estimation of necessary and sufficient levels of radiation power of base stations of cellular communications on urban area are resulted. Analysis is made on the basis of results of behavior simulation of the fragment of a GSM network executed with the use of multibeam radiowave propagation model X3D and the topological model of a fragment of urban area of the central part of Minsk. The results indicate that a high communication quality with blocking probability 0.01 and frequency sharing with SNIR≥12dB can be achieved at levels of BS equivalent isotropic radiated power 43-47 dBm per frequency channel that is essentially less than EIRP levels actually used by GSM/UMTS operators in considered territory. The received results testify that in conditions of excessive BS radiated power the insufficient QoS is caused only by lacks of intrasystem EMC of cellular network, in particular, insufficient quality of network frequency planning and high levels of intranetwork interference. In these cases improvement of intrasystem EMC make it possible to decrease EIRP levels of BS and to improve the electromagnetic safety of population on corresponding areas without degradation of cellular QoS.|
