From 5.-19. October 2022, the Mobile Radio Group at the Institute for Communications Technology conducted channel measurements in a climatic chamber together with colleagues from the Philipps-Universität Marburg. The colleagues from Marburg developed and built the climatic chamber, in which temperatures in a range of 20°C to 45°C and a relative humidity of 30% to 85% can be set. With this climatic chamber and the TU Braunschweig channel sounder, environmental influences on a 300 GHz radio channel were investigated.
