This paper analyzes the frequency dependency of the radio propagation\nchannel's root mean square (rms) delay spread (DS), based on the\nmulti-frequency measurement campaigns in the mmMAGIC project. The campaigns\ncover indoor, outdoor, and outdoor-to-indoor (O2I) scenarios and a wide\nfrequency range from 2 to 86 GHz. Several requirements have been identified\nthat define the parameters which need to be aligned in order to make a\nreasonable comparison among the different channel sounders employed for this\nstudy. A new modelling approach enabling the evaluation of the statistical\nsignificance of the model parameters from different measurements and the\nestablishment of a unified model is proposed. After careful analysis, the\nconclusion is that any frequency trend of the DS is small considering its\nconfidence intervals. There is statistically significant difference from the\n3GPP New Radio (NR) model TR 38.901, except for the O2I scenario.\n
