60 GHz channel directional characterization using extreme size virtual antenna array

In order to provide reliable knowledge about highly resolved directional properties of the radio propagation channel, straight forward beam-forming has been used in this study. Accurate measurement data based on an extreme size virtual antenna array (25×25×25 = 15625 elements) have been provided for an indoor scenario in both line of sight and non-line if sight conditions. The results indicate that the distinct spikes observed in the power-delay profile are caused mainly by specular reflections. There is however also a significant diffuse contribution due to scattering caused by the many smaller objects of the environment. The diffuse paths are spread out in essentially all azimuth and elevation directions except for the empty parts of the floor.
