In this paper, the Weissberger and the Early ITU propagation loss models were used to characterize the propagation loss for a 3G cellular network. Particularly, the 3G network operates at a frequency of 1800 GHz and the case study site is a Gliricidia sepium arboretum which is a Gliricidia sepium Tree Park planted and maintained mainly for scientific study in the annex campus of University of Uyo. Cellmapper app installed on Tecno i5 mobile phone was used to capture the received signal strength; the latitude and longitude of the data capture points, as well as the time and the key cellular network base station data. The relevant mathematical models used to process the measured data and for tuning the Weissberger and the Early ITU propagation loss models were also presented. The Weissberger and the Early ITU propagation loss models were tuned using foliage depth tuning constant. The tuned models prediction performances were evaluated using cross-validation dataset. With the training dataset, the un-tuned Weissberger model had a root mean square (RMSE) value of 21.098 dB while the tuned Weissberger model had a RMSE of 3.375 dB. Similarly, with the training dataset, the un-tuned Early ITU model had a RMSE of 21.970dB while the tuned Early ITU model had a RMSE of 4.019dB. The tuned Weissberger model with the lowest RMSE was adopted for the prediction of the propagation loss in the case study Gliricidia sepium arboretum. Furthermore, the Weissberger model was evaluated using the cross-validation dataset and it had RMSE of 4.507dB.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
