Abstract
We present the design and operation of a sub-THz wideband channel sounder operating at 140 GHz with 2 GHz instantaneous bandwidth. Extensive measurement campaigns in indoor office, shopping mall, and outdoor urban micro environments yield over 50,000 channel impulse responses. We develop a 3GPP-compatible statistical channel model for the 140 GHz band and provide open-source access to the measurement dataset to accelerate 6G research worldwide.
AI Summary
- Sub-THz channel sounder at 140 GHz with 2 GHz bandwidth.
- 50,000+ channel impulse responses across indoor and outdoor environments.
- 3GPP-compatible statistical channel model for 140 GHz band.
- Open-source measurement dataset for 6G research community.
Key Findings
- 1140 GHz propagation shows 15 dB additional path loss compared to 28 GHz mmWave.
- 2Indoor environments provide 2-3 usable reflected paths for NLOS communication.
- 3Atmospheric absorption window at 140 GHz enables practical outdoor links up to 200m.
Industry Implications
Provides essential data for 6G system design at sub-THz frequencies.
Open dataset accelerates global 6G channel modeling research.
Informs 3GPP standardization of sub-THz channel models.
