There are many propagation models that address specific area and application's needs. Each model works well in specific application with specific data and algorithm. Mobile users are now expecting more and more ubiquitous user experience. It is critical to have an integrated model that provides a complete solution for deployment and optimization for different environment and cell types. The Lee macro,...
The Lee propagation prediction model has been well recognized by the wireless industry as one of the most accurate propagation prediction models. This paper discusses innovative approaches dealing with rough digital samples of terrain data and enhancements to the Lee model during the validation process. In general, the Lee model is composed of two parts, the impact of man-made structures and the impact...
