Outdoor-to-indoor path loss model for 8 to 37 GHz band

This paper proposed the path loss model which can cover the high frequency bands above the 6 GHz. The path loss characteristics are analyzed on the basis of measurement results obtained using the 8 to 37 GHz band in outdoor-to-indoor environments. It is clarified that the characteristics depend on incident angle of azimuth, incident angle of elevation and frequency. By taking these dependencies into account, the proposed model can decrease the root mean square error of prediction results to about from 2 dB to 6 dB in the 8 to 37 GHz band.
