Abstract: According to the requirements of 3G network planning, based on ray tracing theory, a method for predicting the strength of wave propagating was proposed. In this paper, it designed and built the 3D database based on GIS to provide the data for prediction, and used the bounding box and octree technologies to accelerate the algorithm. Finally, the result was displayed in 3D visualization. The simulation results show that the method can provide support data for 3G network planning sufficiently, and the visualization effect is good.
