Pathloss predictions from microcell to macrocell

The use of microcells to increase the capacity of cellular mobile communication especially in dense urban areas is an attractive tactic. A number of experimental and theoretical studies have been undertaken regarding propagation in urban microcellular systems. However, predicting the local mean of these microcells requires building data in a 2D or 3D format. Usually, the more detailed the data, the higher the cost and more accurate the model. How to balance the cost and resolution of building data with the accuracy of the model is always a challenging task. A proposed microcell prediction model is necessary to determine the pathloss statistical properties of the cell site based on multiple break points. This model has been validated with the measured data from drive tests performed in various countries/cities, with differing transmitter heights, unique frequencies, and separate cell site parameters and different kinds of mobile environment. The initial findings are that this empirical and theoretical based microcell model performed well in all areas with varying conditions. Secondly, this model can be further reinforced based on the collected measured data. This paper addresses how this model works and also provides the outputs on validation of this model.
