摘要

Radio propagation inside building is governed by mechanisms such as reflection, diffraction, and scattering from different objects. The field distribution inside building is therefore dependent on specific features of its internal structures. This research work investigated GSM signal variation in mud building/rusted corrugated iron sheet roof materials and compared the result obtained with other buildings built with different building materials. Handheld AAronia HF2025E spectrum analyzer was used to carry out the measurements. The frequency bands of five service providers; Airtel, MTN, Globacom, Etisalat, and Starcomm were used as the operating frequencies and handheld portable spectrum analyzer served as receiver which recorded the average signal strength level at each point of the measurement. Results obtained showed among the various combination of materials considered mud building/rusted corrugated iron sheet roof presents higher signal losses of -59.08dBm, followed by mud building/ unrusted corrugated iron sheet roof had an average signal losses of -53.63dBm, the sandcrete building/rusted corrugated iron sheet roof presents signal losses of -50.32dBm, while sandcrete building/unrusted corrugated iron sheet roof had lower average signal losses of -45.37dBm.
