This study presents building pentration loss into and around multi-storey buildings at 900 and 1800MHz based on experimental data obtained through drive test, using Test Mobile System (TEMS) investigation tools. The received signal level was measured inside and outside three buildings; the Senate building of the University of Lagos (B1), Mike Adenuga Towers (B2) and the Sapetro Towers (B3) located in Victoria Island, Lagos Nigeria. The building penetration loss (BPL) was derived from measurements, and the average and standard deviations of the BPL were computed. Results showed that the average BPL of 17.0dB and 13.8dB obtained from building B1 at 900 and 1800MHz, respectively, are comparatively higher than those of buildings B2 and B3. The standard deviation of the BPL shows an increase from 5.2dB at 900MHz to 7.8dB at 1800MHz for building B1, whereas it fell drastically from 8.65dB at 900MHz to 1.40dB at 1800MHz for B2, and a similar behaviour as in B1 is seen for building B3, where it rises sharply from 1.55dB at 900MHz to 6.55dB at 1800MHz. This is in agreement with the general trend of increasing penetration loss with increase in frequency except for building B2 where an anomaly is observed. In order to examine the correlation between the measured and the predicted BPL, cubic regression was used to fit a third order polynomial to the measured BPL. Overrall, the fitted models could find useful applications in the design of novel and robust BPL models for modern multi-floored buildings.

“…The level of attenuation of this radio wave is determined by many factors. The effect of these factors to the received signal inside structures is the main stroke of this signal [5], conducted a research on radio signal propagation measurements at 900MHz, within a hotel building in the city of Udaipur (India), using a model that relied on computing the mean path loss per link. The modality was done using simple measurements made specifically from spectrum allocation.…”

Abstract:The fundamental sculpt of radio waves propagation is the radiation of radio waves from a point-source electromagnetic energy to different directions. In practice, this radiated energy varies and diminishes in strength as it propagates from the point-source to the receiver. The level of attenuation of this radio wave can be determined by many factors. Researchers on urban wireless microcells networks, had very often, focused on measurements and modeling of reflected and diffracted rays from corners of structures and their exterior walls. In some cases the structures in questions were treated as opaque to signal propagating under terrestrial mobile frequency range. The attenuation capacity of these structures forms the basis of this study. Quasi-two-dimensional ray-based model was employed during the study. The transmitting and receiving antennae heights were erected at elevation levels not above the top of an average roof, while the base station antenna was assumed to be at the same height as the mobile station to enable the transmitted rays to propagate in a horizontal plane. This was anchored on the theory that transmitted e-m waves have uniform distribution as it propagated through different layers of the building. The attenuation coefficients of other obstructions in the periphery of the environment were not considered. Furthermore, only the exterior building coordinates were assumed to be known. X (τ) = , which has a pulse-like shape, to estimate the complex impulse response (
