An Assessment of 5G NR Network Planning for Dense Urban Scenario: Study Case of Jakarta City

Abstract

Jakarta city is the capital and the economic center region for one of the largest countries in the world, Indonesia. The massive annual number of migrants that move to Jakarta city municipals; Thousand Islands, South Jakarta, East Jakarta, Central Jakarta, West Jakarta, and North Jakarta, pushed the traffic demand to be doubled or tripled every year. Therefore, it is crucial to prepared the latest cellular technology that could accommodate this considerable traffic. This research aims to use the 5G NR network planning with the frequency of 3.5 GHz and bandwidth 100 MHz to determine the required number of gNodeB for the capacity and coverage planning with user projection from 2021 until 2026 by engaging a case study in a dense urban area, Jakarta city that has a total area of 662.33 km <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . The highest required number of gNodeB for both capacity and coverage planning among the municipals is located in East Jakarta. Capacity planning requires 203 gNodeB. In comparison, coverage planning requires 194 gNodeB. Meanwhile, the total required gNodeB and generated traffic demand forecast for all municipals in Jakarta city is 778 gNodeB and 17.68 Gbps/km <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , respectively.
