95 GHz Sub-THz Multipath Propagation Measurement for Indoor Conference
Room Desktop
Abstract
This study conducts a wideband multi-path propagation measurement at the
95 GHz sub-terahertz band for short-range communication in a conference
room desktop scenario. Regardless of the fact that the current 3rd
generation partnership (3GPP) stochastic channel model (SCM) targets the
frequency up to 100 GHz for various scenarios, neither detailed
measurements at the 95 GHz band nor a compatible channel
modeling/generation framework for indoor short-range communication
scenarios have been conducted. To fill these voids, based on a
real-world measurement at 95 GHz with a bandwidth of 4 GHz, this study
analyzes the multi-path propagation characteristics and yields the
following insights for developing a 3GPP SCM-compatible channel
generation framework at this band. First, the exponential power decay
with delay time and quasi-uniform azimuth angles of arrival (AAoAs) are
observed, which should be revisited to develop a channel generation
framework. Secondly, distribution models for root mean squared (RMS)
delay/AAoA spreads and omnidirectional path loss model are derived,
which serves as a foundation for developing a channel generation
framework at this band. Moreover, these established models are compared
with the recently conducted measurement results at the 60 GHz band in
the same scenario, shedding light on the hypothesis that the models for
these parameters at the 60 GHz can be generalized for the 95 GHz band.
