Abstract :
Experiments of 94-GHz millimeter-wave propagation were carried out in indoor channels, where the propagation path loss and multipath fading are investigated. The results show that the path-loss exponents in the line-of-sight (LOS) and obstructed (OBS) channel are 1.2-1.8 and 3.6-4.1, respectively. The received power of the OBS path is attenuated significantly as compared with that of the LOS path, thereby requiring an additional link-budget margin as well as battery power. In this paper, the use of an artificial reflector is also suggested under OBS conditions in order to avoid significant propagation loss, and then, a comparative study is conducted
