Abstract
This paper presents comprehensive channel measurement results at 300 GHz in indoor and short-range outdoor scenarios relevant to 6G communications. We conduct over 10,000 channel impulse response measurements and develop a statistical channel model that captures the unique propagation characteristics of THz frequencies including molecular absorption, specular reflections, and scattering effects. The model is validated against ray-tracing simulations with less than 2 dB error.
AI Summary
- Over 10,000 channel measurements at 300 GHz across indoor and outdoor environments.
- Develops a validated statistical channel model for THz 6G communications.
- Model accuracy within 2 dB of ray-tracing reference simulations.
- Characterizes molecular absorption, reflection, and scattering at THz frequencies.
Key Findings
- 1Molecular absorption creates frequency-selective fading unique to THz bands.
- 2Specular reflections from smooth surfaces provide useful multi-path components.
- 3Effective communication range at 300 GHz is 10-50 meters depending on environment.
Industry Implications
Essential data for 6G THz system design and standardization.
Enables accurate link budget analysis for 6G short-range high-capacity links.
Informs antenna and beamforming design for THz communication systems.
