Indoor propagation measurements at 94 GHz

Experiments of 94GHz 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 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. In this paper, the artificial reflection by a mirror reflector is also suggested under no LOS environments in order to avoid the significant channel degradation, thereby the power level is found to be improved by 15-20dB.
