Sub-6GHz Channel Sounding Dataset
Sub-6GHz MIMO Channel Sounding Dataset
Double-directional 8×8 MIMO channel measurements in urban outdoor environments at 4.850 GHz, collected in Yokohama City, Japan. Supports 5G/6G channel modeling, beamforming research, and propagation analysis.
Dataset Overview
This dataset was collected by the Radio Signal Processing Laboratory at Niigata University as part of drive measurement campaigns in urban macro-cell (UMa) and micro-cell (UMi) environments in Yokohama City, Japan. Four routes (R3, R4, R5, R6) were driven across three distinct areas: Yuraku, NTTCom, and World Porters (WP).
Each drive covers 3,000 measurement points (sample period: 0.512 s) with co-located 360° panoramic photos (every 10 s, ~150 pcs per route). Valid samples are selected based on vehicle motion, TX field-of-view, and power threshold criteria.
