The Institute for Communications Technology at Technische Universität Braunschweig (TUBS), has worked on THz communications for almost 14 years and has contributed to fundamental research on channel modeling and measurements, overall system design via link and system-level simulation and hardware demonstration using their 300 GHz channel sounder and in-house developed Simulator for Mobile Networks (SiMoNe). By participating in several international as well as national projects, TUBS extended its portfolio of experience in THz communications. Additionally, TUBS has led standardization and regularization efforts in this new frequency range.
