Measurement and ray-tracing simulation of the 60 GHz indoor broadband channel: model accuracy and parameterization

Abstract

In this paper, we examine millimeter wave propagation in an application-oriented indoor environment by means of broadband channel measurements and ray-tracing simulations. Fundamental issues concerning the choice of simulation parameters are discussed. We investigate the accuracy of ray-tracing predictions in the millimeter wave band with regard to wideband analyses. The results indicate that ray-tracing simulations are useful to predict channel measures like the path loss and the RMS delay spread. However, fundamental differences can be observed by examining the temporal structure of the channel impulse responses and of the spatial fading characteristics which give rise to further analyses.
