摘　　要：Sub-terahertz(Sub-THz),defined as the frequency bands in 100-300 GHz,is promising for future generation communications and sensing applications.Accurate channel measurement and modeling are essential for development and performance evaluation of the future communication systems.Accurate channel modeling relies on realistic channel data,which should be collected by high-fidelity channel sounder.This paper presents the measurement-based channel characterization in a large indoor scenario at 299-301 GHz.We firstly review the state-of-the-art channel measurements at sub-THz frequency bands.We then presented a VNA-based channel sounder for long-range measurements,which uses the radio-overfiber techniques.Channel measurements using this channel sounder are conducted in a large hall scenario.Based on the measurement data,we calculated and analyzed key propagation channel parameters,e.g.,path loss,delay spread,and angular spread.The results are also analyzed both in the line-of-sight(Lo S)and noneLo S(NLo S)cases.The large delay components in the measurements demonstrate the possibility of the longrange channel measurement campaign at 300 GHz.
