Abstract

This report presents a study on the propagation coverage for general scenarios using Ray-Tracing Technique. As transmitted signal propagates in the transmission medium (outdoor scenarios), the signal power will come across reduction when it reaches the receiver. The reduction is most probably caused by the obstacles that the signal ray hit along the way of its transmission. Signal power reduction at the receiver is dependent on three major factors, the separation distance between the transmitter and the receiver, the materials present in the transmission medium and the angle of incidence of the signal ray on the materials. The objective of this study is to predict the coverage for general scenarios (outdoor scenarios) in terms of maximums distance and obstacles in the vicinity. The output/coverage of the simulation have to be done and shown in MATLAB 2D. The methodology is divided into four major phases to systematically carry out the whole project; the Planning phase, the Conducting phase, the Designing phase and the Analysis phase. At the closing stages, the results shows that propagation coverage drops significantly when separation distance of transmitter and receiver increases. Also, the results show that the power received decrease as the angle of incidence of rays increase. This implies that power received is reliant on the materials in the transmission medium to constitute the effect in terms of relative permittivity and electrical conductivity.
