Abstract

The implementation of 5G cellular technology in Indonesia needs to be studied in several aspects. So that several cellular operators in Indonesia have experienced difficulties in implementing 5G cellular technology in Indonesia, especially in Pontianak City. Therefore, the analysis of pathloss values in cellular systems is an approach to large-scale fading aspects to calculate service coverage. This research calculates the pathloss value with a case study in Pontianak City with micro urban cell characteristics. In this research, ABG (Alpha-Beta-Gamma) prediction model is used with working frequency of 3.5 GHz and 28 GHz with bandwidth of 100 MHz. The calculation results of the ABG prediction model at a frequency of 3.5 GHz has a value of 91.78 dB for LOS conditions and in NLOS conditions has a value of 123.26 dB. While at a frequency of 28 GHz the pathloss value generated is 110.71 dB in LOS conditions, while in NLOS conditions the value is 140.42 dB. The 28 GHz working frequency has a slightly higher pathloss value than the 3.5 GHz frequency and has a difference in value of 18.99 dB for LOS conditions while in NLOS conditions it has a difference in value of 17.16 dB.

利用 abg 预测模型分析坤甸市微型城市小区的 5g 蜂窝技术路径损耗预测情况

在印尼实施 5G 蜂窝技术需要从多个方面进行研究。因此，印尼的几家蜂窝运营商在印尼实施 5G 蜂窝技术时遇到了困难，尤其是在坤甸市。因此，分析蜂窝系统中的路径损耗值是计算服务覆盖范围的大规模衰减方面的一种方法。本研究以坤甸市为例，计算了具有微型城市小区特征的路径损耗值。本研究采用 ABG（阿尔法-贝塔-伽马）预测模型，工作频率为 3.5 GHz 和 28 GHz，带宽为 100 MHz。ABG 预测模型在 3.5 GHz 频率下的计算结果是，在 LOS 条件下为 91.78 dB，在 NLOS 条件下为 123.26 dB。而频率为 28 GHz 时，在 LOS 条件下产生的路径损耗值为 110.71 dB，在 NLOS 条件下为 140.42 dB。28 GHz 工作频率的路径损耗值略高于 3.5 GHz 频率，在 LOS 条件下，路径损耗值相差 18.99 dB，而在 NLOS 条件下，路径损耗值相差 17.16 dB。
