RIS-aided path loss model evaluation in real-life scenarios

This dataset contains experimental measurement data collected in wireless communication scenarios with a Reconfigurable Intelligent Surface (RIS), both in an anechoic chamber and in an office environment. The purpose of the measurements was to gather received signal strength values and compare them with the received power estimated using Tang’s RIS path loss model, under different azimuth configurations and distances between the RIS and the receiver line.

The dataset includes:

• Azimuth [°] – orientation angle of the receiving antenna (relative to RIS),

• Pattern – identifier of the RIS configuration or radiation pattern used during the measurement,

• Received signal strength (Rx power, [dBm]) – the power of the received signal at the measurement point.

File naming convention

Each file name encodes the experimental setup.
Example:

• ainfo_lab_D_1p5m.csv

  • ainfo → measurement with ainfo antenna as the receiver,

  • lab → measurement conducted in laboratory conditions, i.e. an indoor office-type environment,

  • D_1p5m → distance D = 1.5 m between the RIS and the receiver line.
