Abstract
This paper presents ray tracing simulations for wave propagation at millimeter-wave frequencies to be applied in future 5G wireless communications. Since attenuation and blockage of millimeter-wave propagation in urban are much more severe than those at microwave frequencies, the line-of-sight rays and non-line-of-sight reflected rays should be dominant propagation mechanisms. Field distributions will be more constrained and therefore new approaches to improve the coverages of the 5G wireless communications will be needed. The ray tracing method can be applied to evaluate those approaches for improving field coverages in the deployment of the 5G base stations.
