摘要：

The short wavelength of the mmWave frequency band suggests that even narrow-width blockers affect the mmWave signal strength. There is a lack of literature investigating the effect of small-sized blockages. In this study, we present new measurement results for five metallic objects, mimicking objects indoors or in the street, where the obtained resulting loss is in the range of 10-30 dB. Based on these new results, the knife-edge diffraction (KED) blockage model that is provided by the third-generation partnership project (3GPP) standards body, in general, fails to replicate the results. Thus, we investigate the suitability of the enhanced KED blockage model, called the mmMAGIC blockage model, for these blockers, which generally works well in capturing the measured attenuations.
