5G NR Planning at Frequency 3.5 GHz : Study Case in Indonesia Industrial Area

Abstract

This research used the 5G NR network planning with the frequency of 3.5 GHz simulated using the Mentum Planet 7.2.1 software with the planning method in the coverage side by employing a case study in Pulogadung industrial zone with a total area of 5 km2. This planning used the 5G NR planning method with the propagation model in accordance with the plan, that is, UMa (Urban Macro – Street canyon) model based on the standard of 3GPP TR 38.901, using 8 design scenarios for the uplink; and downlink; outdoor-to-outdoor (O2O) and outdoor-to-indoor (O2I); line of sight (LOS) and non-line of sight (NLOS) conditions. The simulation result showed that the design with the downlink scenario required more sites to fulfill the area services that the uplink scenario since influenced by the link budget parameter, that is, the value of interference margin downlink which is greater than that of the uplink margin interference; From all scenario parameters of SS-RSRP observed, scenario 1 (downlink-O2O-LOS) had the highest average SS-RSRP of -92.95 dBm and the lowest average SS-RSRP resulted from the scenario 2 (uplink-O2O-LOS) of -97.16 dBm. The average SS-RSRP value was influenced by the number of sites covering the planning areas that scenario 1 had the highest SS-RSRP parameter.
