Channel Sounding 6G

Technical Explanation

Designing reliable 6G transceivers requires deep empirical knowledge of how high-frequency radio waves bounce, scatter, and attenuate in the real world. 6G Channel Sounders transmit ultra-short picosecond pulses or wideband chirps across frequencies up to 300 GHz. Rotating horn antennas or virtual antenna arrays capture the exact angle-of-arrival, angle-of-departure, delay spread, and Doppler shift of every multipath ray in outdoor and indoor environments.

Key Functions

• Measuring double-directional spatial angle-of-arrival and angle-of-departure multipath rays
• Sub-nanosecond delay resolution resolving multipath reflections separated by centimeters
• Full polarimetric characterization (co-pol and cross-pol) across frequencies up to 300 GHz
• Feeding empirical multipath measurement databases to 3GPP channel modeling committees
• Validating ray-tracing simulation accuracy against real-world physical environments
