Abstract :
The use of microcell to increase the capacity of cellular mobile communication, especially in the dense urban areas, is an attractive possibility. A number of experimental and theoretical studies have been undertaken regarding propagation in the urban microcellular system. A microcell prediction model based on building thickness is developed to predict the statistical properties of the cell site. The model is validated based on several drive tests performed in different countries/cities with different transmitter heights, frequencies, cell-site parameters, and mobile environments. The first finding is that this empirical-based microcell model performed well in all these areas with a combination of various parameters. Second, the terrain does have a major impact on microcell prediction. This paper addresses the sufficient requirement of having only a two-dimensional (2-D) microcell prediction model. The impact of terrain contour on the microcell prediction is not included
