Fifth generation (5G) mobile networks are expected to play an increasing role\nin industrial communication with private mobile communication networks deployed\non company premises. For planning, standardization and product development, it\nis crucial to to thoroughly understand the radio channel characteristics of\nsuch environments. Frequencies around 3.7 GHz were already reserved by\nregulation authorities and to meet the increasing demand for higher bandwidths,\nspectrum in the millimeter wave range around 28 GHz is targeted. This paper\npresents a wideband channel measurement campaign at both 3.7 and 28 GHz with\ndirection-of-arrival information at 28 GHz. The results are compared to the\n3GPP TR 38.901 Indoor Factory model and to two other recent papers. Evaluation\nof path loss and RMS delay and angle spread show the unique nature of\nindustrial indoor environments.\n
