- Abstract
- This paper investigates measurement-based omni-directional millimeter-wave propagation characteristics for an indoor corridor environment. The omnidirectional characteristics were obtained with actual omnidirectional antenna measurements both at TX and RX, and not by synthesizing directional antenna measurements. With wideband sounding at 28, 38, 71 and 82 GHz, we analyzed path loss, shadow fading, excess loss and delay spread characteristics. In the path loss and the excess loss analyses, evident differences between the LOS and the NLOS were observed due to the waveguide effects. In the excess loss and the delay spread analyses, gaps were observed between the relative lower mmWave frequencies (28 and 38 GHz) and the upper frequencies (71 and 82 GHz).
