Here we provide the dataset containing the power measurements carried out in the anechoic chamber of TU Darmstadt.
The test was performed under the following conditions:
- TX at 1.1m away from RIS with 33° elevation angle and θt = [20°,90°]
- RX at 6.3m away from RIS with -3° elevation angle and θt = [90°]
- Horn antennas gain = 13.5 dBi
- OFDM QPSK-modulated symbols with 5 MHz of bandwidth, numerology that meets LTE requirements.
- TX power per subcarrier = -30 dBm
- Reference signal received power (RSRP) sampling at RX
- Noise floor = -90dBm
For more details, please refer to sec. 5 of our paper.
In the CSV file, the pair (θn, Φn) defines the RIS main beam location: θn for the azimuth and Φn for the elevation. Instead, θr indicates the angle for the radiation pattern varying with a step of 3° on the azimuth.
In the RIS_beamforming file, data regarding how the RIS is able to generate beamforming by changing the number of active antenna elements.
