Accurate Empirical Path Loss Models with Route Classification for mmWave Communications

This paper presents accurate empirical path loss models with route classification for the high band frequency of 5 G wireless. Propagation routes are mainly classified into line sight (LOS) and non-line-of-sight (NLOS). The NLOS 2 separate routes, namely, Hard_NLOS Soft_NLOS. Their include free-space (Lfs) multiscreen diffraction (Lmsd) together reflection from building blocks. However, these can be combined a single formula. were fitted measured data at frequencies 28 GHz 73 GHz. These compared four 5G models, namely 5GCM, 3GPP, METIS, mmMAGIC. results show that separated provide good agreement, especially hard those minimum MAE 4.45 dB, 4.34 6.72 dB route, soft an all-NLOS respectively, dual-band frequency.
