Path Loss Model Based on Cluster at 28GHz in the Office and Corridor Environments

This paper presents 28GHz path loss model based on cluster obtained from channel measurement campaigns with rotating platforms and directional antennas in the office and corridor environments. As the sequence number of cluster increases, the path loss exponents (PLEs) increase while shadow factors also have the growing tendency. The PLE of all-clusters is the least because of multi propagation paths, and the LOS PLEs of corridor scenario are less compared with that of office scenario because of corridor's long and narrow structure. This path loss model not only contains cluster characteristics, but also unites directional and omnidirectional model into the same framework, which to some extent improves the 5G mmWave channel model.
