Abstract

In this paper, we present 60 GHz outdoor to indoor directional propagation measurements done on the main campus of The American College of Greece (ACG). The receiver was placed in offices and corridors, and the transmitter was placed at over 160 different points in a large parking lot. We collected over 2.4 million power measurements, from four similar runs, with distance up to 220 meters. Slope-intercept fits to each run separately resulted in a RMS error of under 2.5 dB, where three out of four slopes are close to 4, and one is close to 2. Excess loss relative to Free space exceeded 30 dB for distances beyond 20 m. Azimuthal gain degradation due to scattering was 7.5 dB at the 90th percentile, while temporal power fluctuations resulted in a minimum Rician K factor of 9 dB for 90% of measured links.
