Global system for mobile communication (GSM) became the most active industry in our country Nigeria, since its inception in 2004. The number of service providers keeps on increasing, but the quality of services (QoS), provided is still low. This research work, studied by way of extensive measurements, the received signal strength inside buildings constructed using different types of building materials for both the structure and the roof. This is with a view to finding a signal attenuation margin that will improve the indoor propagation model. The degree of attenuation on the received signal may be used to provide a margin in GSM radio link planning so as to compensate for such loss. The measurements were conducted in selected areas in Jigawa metropolis where these types of buildings are common. Four geographical locations were used as case study within Jigawa metropolis namely, Dutse, Kazaure, Hadejia, Gumel and Ringim. Signals radiated from four GSM service providers (namely, MTN, ETISALAT, Glo and Airtel) were used as basis for the measurements. Spectrum analyzer mounted on a trolley and controlled by a PC was used for this work; measurements on straight routes in corridors, rooms and the balcony were performed with equidistant measurements points. Several measurements campaigns with different location at 230 and 1500MHz were undertaken. Based on the results obtained, we conclude that, among the combination of building materials studied in this research mud building/rusty zinc accounted for higher signal losses while sandcrete building/good zinc roof accounted for lower signal losses for all the network providers considered in this study.
