Resumen
Recently, there has been an interest in modelling of the communication process. One of the most important reasons for developing such models is to forecast what will be happened. A number of modelling studies provide several assumptions and use different theories. up to now, there is still a lack of an optimum model which can be used for the purpose of future communications. This indicates a need to understand the aspects of communication modelling and the motivation behind improving our knowledge in this field. This paper details work done to design a propagation model of a wireless communication system to give a forecast of signal behavior. Data for this study were collected using a wireless communication system employed in the outdoor environment. The final part of this paper gives a summary and description of findings which include a comparison between the experimental and simulation results. The model finally shows a similar trend with the observation.
