Network Planning Analysis of 5G Millimeter-Wave Deployment in Indonesia’s Dense Urban Area

An essential resource for the deployment of 5G technology is the frequency spectrum. A high spectrum provides high data rates and a large bandwidth to support many new devices, applications, and services that meet the needs across multiple domains. However, a high spectrum has a smaller range (10–100 m
²
) with a sub-6 GHz spectrum. So, it takes careful design for 5G implementation using high frequencies (mmWave). As a result, this research will plan a 5G New Radio (NR) network implementation employing a 28 GHz mmWave frequency. The dense urban scenario research design was carried out by selecting Central Jakarta as the research object. Central Jakarta was chosen as a pilot project because it is feasible in market potential and infrastructure support to pre-pare 5G implementation in Indonesia. The capacity approach considers the data rate and users, while the coverage approach considers Maximum Allowable Path Loss (MAPL) parameters and path loss propagation. A propagation model based on 3GPP TS 38.901 UMi Street. The results of this study indicate that Central Jakarta requires a traffic demand of 4.72 Gbps/km
²
. In addition, the deployment of a 5G NR network with mmWave frequency based on the capacity planning approach requires 33 uplink and 12 downlink gNobeB. As a result, the coverage area necessitates 738 uplink gNodeB with a coverage area of 69 m
²
and 130 downlink gNodeB with a coverage area of 370 m
²
. Based on these results, the gNodeB needed for Central Jakarta was selected based on downlink coverage with 738 gNodeB.
