Indoor propagation measurements at 94 GHz

Experiments of 94 GHz millimeter wave propagation were conducted in indoor environments where the propagation path loss and log-normal fading are investigated in a typical lecture room and corridor. The results show that in a LOS channel the path loss exponents for a room and corridor are found to be 1.8~2.5 and 1.7~1.8, respectively. The artificial reflection by a mirror reflector is also suggested under non-LOS environments in order to avoid significant channel degradation, thereby the power level is found to be improved by 15~20 dB
