Summary:Site-specific millimeter-wave propagation prediction requires data of the environment under study, which is usually not available for indoor scenarios. With means of laser scanning the details of the indoor environment can be captured accurately in the form of a point cloud. The total field is estimated as a sum of paths backscattering from the point cloud, where the electromagnetic scattering for each path is calculated with a single-lobe directive model. In this paper we focus on predicting the radio wave propagation in a large office environment at 70 GHz, where the accuracy is evaluated by comparing measured and predicted mean delays and delay and azimuth spreads. We also present a method for dealing with shadowing in the indoor environment. The results show good agreement between measured and predicted delay and azimuth spreads for line-of-sight links, and also non-line-of-sight links can be predicted with reasonable accuracy.
