Comparison and Analysis of the Path Loss Models used in E Band Communication System

Fifth - generation cellular systems are likely to operate in or near the millimeter-wave (mm Wave) frequency bands of 30300 GHz, where vast spectrum currently exists with light use. At these mm Wave frequencies, the wavelength is so small that highly directional, steerable antennas may be used in novel ways. This research work presents empirically-based large scale propagation path loss models for fifth generation cellular network planning in the millimeter-wave spectrum based on real-world data at 28 GHz and 38 GHz. The model in this paper allows future realistic modeling of propagation conditions for millimeter wave transmission in urban microcellular environments. This model also suggests that in future millimeter wave communications, mobile devices shall deploy antennas with higher gains to compensate for the additional path loss due to the frequency leap from low microwave to the millimeter wave regime.
