The dataset includes color images, corresponding depth maps, inertial measurement unit (IMU) readings, channel response between a 5G massive multiple-input and multiple-output (MIMO) testbed and user equipment, audio recorded by 12 microphones, and accurate six degrees of freedom (6DOF) pose ground truth of 0. 5 mm.

Compared to other USRP-based channel sounders, our design is versatile, eases the requirements on the data link between the USRPs and the host, limits the measurement data size, and increases the signal-to-interference-plus-noise ratio due to averaging.

Therefore, we investigated the validity of the published channel models at sea by means of path loss measurements using a LoRa link with a transmitter antenna height of 0. 35 m and a base station antenna height of 2. 65 m and 5. 2 m. Our results show that the round earth loss model is not accurate at these antenna heights.
