Query: Large-Scale Parameters of Spatio-Temporal Short-Range Indoor Backhaul
  Channels at 140 GHz   The use of above-100 GHz radio frequencies would be one of promising
approaches to enhance the fifth-generation cellular further. Any air interface
and cellular network designs require channel models, for which measured
evidence of largescale parameters such as pathloss, delay and angular spreads,
is crucial. This paper provides the evidence from quasi-static spatiotemporal
channel sounding campaigns at two indoor hotspot (InH) scenarios at 140 GHz
band, assuming short-range backhaul connectivity. The measured two InH sites
are shopping mall and airport check-in hall. Our estimated omni-directional
large-scale parameters from the measurements are found in good match with those
of the Third Generation Partnership Project (3GPP) for new radios (NR) channel
model in InH scenario, despite the difference of assumed link types and radio
frequency range. The 3GPP NR channel model is meant for access links and said
to be valid up to 100 GHz, while our measurements cover shortrange backhaul
scenarios at 140 GHz. We found more deviation between our estimated large-scale
parameters and those of the 3GPP NR channel model in the airport than in the
shopping mall.
