The use of above-100 GHz radio frequencies would be one of promising\napproaches to enhance the fifth-generation cellular further. Any air interface\nand cellular network designs require channel models, for which measured\nevidence of largescale parameters such as pathloss, delay and angular spreads,\nis crucial. This paper provides the evidence from quasi-static spatiotemporal\nchannel sounding campaigns at two indoor hotspot (InH) scenarios at 140 GHz\nband, assuming short-range backhaul connectivity. The measured two InH sites\nare shopping mall and airport check-in hall. Our estimated omni-directional\nlarge-scale parameters from the measurements are found in good match with those\nof the Third Generation Partnership Project (3GPP) for new radios (NR) channel\nmodel in InH scenario, despite the difference of assumed link types and radio\nfrequency range. The 3GPP NR channel model is meant for access links and said\nto be valid up to 100 GHz, while our measurements cover shortrange backhaul\nscenarios at 140 GHz. We found more deviation between our estimated large-scale\nparameters and those of the 3GPP NR channel model in the airport than in the\nshopping mall.\n
