Abstract

The 4G LTE technology is widespread in almost all regions in Indonesia, including Solok City in West Sumatra, where this study was conducted. Based on the results of the 1800 MHz frequency drive test, the RSRP value was in the good category (81.44%), but the SINR value was in the poor category (56.96%). Furthermore, the results of the 2100 MHz frequency drive test showed that the RSRP value was in the poor category (58.11%), and the SINR value was also in the poor category (54.62%). These results indicate that the area had poor network quality. Therefore, this study aimed to optimize the Bad Spot Area in Solok City using the Automatic Cell Planning (ACP) method. The ACP method optimization results show that at the 1800 MHz frequency, the value of the ten cells is in the interval -127.84 ≤ RSRP ≤ -99.34. Meanwhile, at the 2100 MHz frequency, the value of the seven cells is in the poor category, which is in the interval -136.39 ≤ RSRP ≤ -111.03. In the 2100 MHz frequency, there is a decrease in RSRP value in the poor cate-gory from 43.27% to 41.85%. SINR parameter optimization results of 2100 MHz frequency, the percentage of a very good category is higher with a value of 51.40% than 44.16% at 1800 MHz frequency.

Abstract

The increase in service users causes network problems, such as poor signal quality, sudden signal loss, or no network at all, To improve network quality, improvements are made to service coverage. One of them is by adding eNodeB. With the addition of eNodeB, network maintenance must be carried out to ensure identification and improvement related to network coverage and performance. If maintenance is not performed, it can cause bad spots, one of which is cell overshooting. The purpose of this research is to analyse the effect of cell overshooting on 4G LTE network coverage and quality parameters. 4G network coverage parameters are: Reference Signal Received Power (RSRP) and 4G network quality parameters namely Signal to Interference Noise Ratio (SINR). From the drive test results obtained 80.77% of 546 samples on RSRP parameters ≥ -100 dBm and 32.78% of 546 samples on SINR parameters ≥ 3 dB. The low SINR parameter of the drive test results is caused by bad spot overshooting cell interference that occurs at site 4253364E and site MC425CC02E with sites around the bad spot area. From the analysis, it can be seen that bad spot overshooting cell affects network quality, while network coverage parameters do not. Where the RSRP parameters at the bad spot point are -87 dBm and -92 dBm and SINR parameters at the bad spot point are -1 dB and -3 dB.

Abstract

In the development of 4G LTE technology, network speed (Throughput) in several regions has increased or decreased. Network speed (Throughput) certainly cannot be separated from Modulation.  In modulation there are several kinds of modulation schemes, be it QPSK modulation, 16 QAM modulation, and 64 QAM modulation. The modulation scheme is instrumental in increasing throughput. Based on several previous studies, they only check the Throughput parameters without doing a more in-depth analysis of the modulation scheme which also plays a very important role in network speed (Throughput). For this reason, it is necessary to carry out an analysis related to the effect of modulation on the throughput value. To find out the effect of modulation on throughput, it is necessary to take data in the field, the method used is the Drive Test method. Based on the results of the Drive Test, QPSK modulation has a Throughput value of 5.247.4 Kbps, modulation of 16 QAM has a Throughput value of 27.293.9 Kbps and modulation of 64 QAM has a Throughput value of 65.275.1 Kbps. Based on the data in the field and in terms of calculations, the modulation that most affects the throughput value is the modulation of 64 QAM. Modulating 64 QAM having 64 symbols where each symbol consists of 6 bits will make the data rate at throughput higher. This also applies to the use of modulation of 16 QAM (16 symbols with 4 bits) and QPSK (4 symbols with 2 bits).

Abstract

This study aims to evaluate the quality of 2G and 4G networks on Telkomsel operators in Gunung Talang District and Danau Kembar District, Solok Regency, West Sumatra. This research was conducted using the drive test method using TEMS Pocket and TEMS Discovery devices for network data collection and analysis. The 2G network measurements were conducted based on Rx Level and Rx Quality parameters. In contrast, the 4G network was evaluated based on RSRP (Reference Signal Receive Power) and SINR (Signal Interference to Noise Ratio) parameters. The measurement results on the 2G network show that the average Rx Level is at -85.1 dBm, with very poor signal quality reaching 27.14%, while the network quality based on Rx Quality is classified as excellent with an average value of 0.9 dB, which reaches 82.21%. On the 4G network, the average RSRP was -101.7 dBm with a good signal dominance of 30.68%, but the network quality based on SINR was lower, with an average value of 12.3 dB, where 46.98% of the signal was classified as fair. In addition, several bad spot areas were found to be affected by natural obstacles such as hills, cliffs, and tall trees that block the signal. The recommendation from this research is to optimize the nearest site to improve signal quality in these areas, especially to reduce overshooting problems that occur in certain sectors. This research is expected to be a reference for operators in improving network quality in the areas studied

Abstract

Demand for mobile data services and people’s dependence on 4G LTE networks continue to increase. However, the quality of service (QoS) of this network still requires improvement, especially regarding the effect of QoS on throughput at specific frequencies. The research gap lies in the lack of indepth analysis of the impact of QoS parameters on network performance at frequencies of 2,100 MHz and 2,300 MHz. This study evaluates the effect of QoS parameters, such as delay, jitter, and packet loss, on throughput in 4G LTE networks at both frequencies. The research methodology uses an experimental approach with throughput, delay, jitter, and packet loss measurements in various network conditions. The results showed that delay (17.2174 ms to 37.0322 ms), jitter, and packet loss significantly influence throughput, ranging from 624.5 Kbps to 1,322.4 Kbps. The 2,100 MHz frequency tends to show better performance than 2,300 MHz. This study concludes that optimizing QoS parameters, especially delay and jitter, can significantly improve 4G LTE network performance. These findings provide practical contributions for mobile operators in improving network quality and customer satisfaction and open opportunities for further research on other frequencies or newer network technologies.
