Lee Microcell Propagation Model: A Complex Case Empirical Study
Authors: , , , , ,
Abstract: Power propagation model construction for mobile communications is very important in order to assure the quality of physical communication. The Lee model allows predicting the path loss in different scenarios: terrain, suburban, urban, over-aquatic, among others. It has been used to model the communications in several scenarios around the world. It also can be used to model the communication at different frequencies and transmission power. Other derived models have also been published recently. In this paper we present a new usage of this model to predict the path loss in a complex scenario. Recent case study works apply this model to a specific scenario that only considers problems with one kind of transmission media. We consider different kind of environments present in our scenario. We have done an analysis that includes a deep insight on obstruction phenomenon caused by buildings and how they impact signal propagation. We also analyze a microcell in which vegetation is present. The novelty is that the two above environments are present in our case study and show that the Lee’s model is very appropriated in both cases. This complex scenario (living lab) allows us to design an academic realistic learning tool for some key concepts about signal propagation theory and practice.
