Required levels of radiation power of GSM base stations on urban area taking into account attenuation in buildings and intrasystem EMC

Results of estimation of required levels of radiated power of base stations of cellular communications at the voice communication mode on urban area, taking into account attenuation of radio waves in buildings, and levels of intranetwork interference, are resulted. Analysis is made on the basis of behavior simulation of the fragment of GSM network at voice communication mode, 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, by comparison of statistical distributions of levels of signals received on various floors of buildings taking into account average attenuation of radio waves on each of floors, and also statistical distributions of SNIR values for the coincident conditions. The results indicate that in typical urban areas of medium number of building storeys the high communication quality at BS equivalent isotropic radiated power ≥43-45 dBm in GSM-1800 networks can be achieved only by diagnostics and improvement of intrasystem EMC of cellular network and network optimization, including optimization of spatial structure and of frequency sharing, but not by increase of radiated power of stationary and mobile GSM radio equipment.
