38 GHz Channel Modeling for 5G Communication at Pekanbaru City

Abstract

The fifth-generation (5G) telecommunications technology has been implemented in Indonesia in June 2021. Its implementation is only limited to certain urban areas and does not cover the entire territory of Indonesia. Therefore, to support optimal results when implemented in Pekanbaru City, 38 GHz channel modeling needs to be done. The 38 GHz frequency is one of the recommended frequencies for 5G. In the channel modeling, geographical parameters such as temperature, humidity, air pressure, rainfall are important input parameters. This is because each region has different geographical parameters so that it will produce different canal modeling as well. This channel modeling uses NYUSIM as a tool to generate parameters such as Path Loss (PL), Power Delay Profile (PDP), Angle of Arrival (AOA), and Angle of Departure (AOD). The scenario chosen was Urban Microcell (UMi) with Line of Sight (LOS) and Non-Line of Sight (NLOS) conditions. The results obtained that the Path Loss value for NLOS is higher than the Path Loss value under LOS conditions, the directional PDP value for the received power is higher than the omnidirectional PDP value, and the PDP directional standard deviation is smaller than the omnidirectional PDP
