In this paper we investigate the impact of the use of Transmitting Reconfigurable Intelligent Surfaces (T-RISs) on the indoor millimeter wave (mmWave) radio channel characteristics. To this purpose, two measurement campaigns were conducted by employing a T-RIS array and a virtual cubic array (VCA). The multipath component extraction was performed to embed the T-RIS based antenna pattern and evaluate the effect on large-scale parameters such as the path loss, delay and angular spreads.
