Impact of Interference and Low Signal Power on the Radio Performance and Design of GSM Network in High Buildings

This paper presents the results of our experimental investigations of the impact that the radio interference and low signal power exhibit on the global-system-for-mobile-communication (GSM) network radio performance degradation in exceptionally high buildings, which are exposed to line-of-sights towards as many as hundreds of base stations and so to as many high-power signals and, consequently, excessive handovers and failed call attempts. During our measurement campaign and the succeeding analyses, we identified and qualified these impairments and the degradation of the quality of service, particularly focusing a dominant, 150- meters-high and only about 50-meters-wide twist tower of 38 floors, situated in the city of Sarajevo. The significance of the well accomplished measurements campaign is the prerequisite for successful design of the indoor GSM system that needs to be accordingly applied in such an environment, as we proposed.
