Abstract: This paper presents a proof of concept of a Non-Line-of-Sight Terahertz communication link enabled by a reflective surface to unlock limitation of point-to point Line-of-Sight use cases, with validation of the link using real internet protocol frames. The system is composed of E-band modems, first characterized in back-to-back measurements in the WR-12 (E-band). The THz over-the-air link budget analysis is performed based of the integration of the reflective surface with dedicated THz front-ends that extend the E-band to H-band (WR-3). The proof-of-concept is done in a lab configuration with a 12 meters link and high gain antennas. This is a first milestone for the use of THz bands in indoor industrial scenarios for network-to-machines or machines-to-machines connections.
