5G Channel Model for Frequencies 28 GHz, 73 GHz and 4 GHz with Influence of Temperature in Bandung

Ismalia Rahayu, Ahmad Firdausi

Abstract

The 5G channel model is the latest research on future cellular communication by considering the proposed millimeter wave (mmwave) as an enabling technology for the realization of connectivity in the 5G era. However, mmwave signal propagation suffers a high propagation loss to sensitivity to delay, resulting in a high probability and a low signal to signal ratio (SNR). This can take into account the potential for millimeter wave (mmwave) frequencies of 28, 73 and 4 GHz which are capable of meeting wide bandwidth requirements and data rates of up to Gbps for various scenarios such as Urban Microcell (UMi) and Urban Macrocell (UMa). The area used to conduct this research is in Indonesia because it is a tropical region that has high rainfall so that it can determine the effect that occurs when it is at maximum and minimum temperatures in each month. Therefore, to determine the characteristics of the 28, 73 and 4 GHz channels in the city of Bandung. This study discusses large-scale mmwave characteristics such as path loss, delay spread and power delay profile for line-of-sight (LOS) and non-line-of-sight (NLOS) cases and compares directional and omnidirectional propagation. In this study the Urban Microcell (UMi) scenario was carried out at a distance of 20 meters to 200 meters with a frequency of 28 GHz and 73 GHz, then for the Urban Macro cell (UMa) scenario at a frequency of 4 GHz with a distance of 50 meters to 500 meters.
