In this paper, the spatial consistency of wireless massive single- input-multiple-output channels in a cellular small cell scenario is evaluated based on measurements taken in Berlin city. The evaluation is done by computing the similarity of covariance matrices over the distance. As similarity measure the correlation matrix distance is used. A classification of the measurements tracks based on the shape of the curves into four different categories is done. The results in this paper indicate that spatial consistency is a highly deterministic property in the sense that it depends strongly on the individual environment and not so much on large scale parameters. Therefore, we conclude that spatial consistency is not sufficiently modelled by the current 3rd Generation Partnership Project feature.
