Abstract

Information technology has now become a primary need for many individuals, facilitating access to various needs, including work, learning, and other activities. Mobile phones allow users to stay connected to the internet without interruption, even when traveling out of town, thanks to their ability to switch between cells or through a process known as handover. The focus of this article is on the impact of handover on 4G LTE networks. The data collection approach in this research uses the drive test method by utilizing the tems pocket application to retrieve internet network data. The research results highlight the importance of understanding how handover can affect 4G LTE network performance. With the role of information technology increasingly dominating everyday life, a deep understanding of technical aspects such as handover has become essential to maintaining the quality and efficient availability of cellular communications services.

Abstract

The growing demand for network services leads to an increase in traffic load on eNodeB, resulting in decreased network quality and performance, necessitating optimization. This research analyses the results of optimising 4G reference signal received power (RSRP), signal to interference noise ratio (SINR) and throughput parameters using the automatic cell planning (ACP) method. ACP has been shown to significantly improve the performance and quality of 4G LTE networks compared to traditional cell planning methods. Based on the standard parameter RSRP, increased after ACP optimisation which is dominant in the range ≥ -100 s.d ˃ -85 dBm and obtained an average value of -98.59 dBm with good category. The average SINR has increased by 18.23 dB with a good category. The dominant throughput is in the 14,000 Kbps range with an average value of 50,241.08 Kbps with the excellent category. The ACP method can enhance the performance of 4G LTE networks, potentially addressing operator issues of unstable network quality due to poor coverage. The ACP method significantly enhances 4G LTE network performance, coverage, and user experience, potentially addressing unstable network quality due to poor coverage. This research is crucial for both users and the telecoms industry.

Abstract

Nanggalo Subdistrict is one of the sub-districts located in the city of Padang, West Sumatra Province. The advantages of data transfer speeds owned by 4G Long Term Evolution (LTE) make telecommunications operators compete with each other to provide the best service quality, but there is still a decrease in network quality in the Nanggalo District area at Telkomsel and Tri operators. So it is necessary to do a drive test to measure and find out the network quality of the two operators. Measuring the quality of a 4G network with RSRP, SINR, and Throughput parameters and how to retrieve data is a benchmark. The software used is TEMS Pocket to take measurement data during the drive test, TEMS Discovery Software to process the data of the test drive results. The comparison results were obtained in Nanggalo District for Tri operator to have better network quality, which can be seen in the SINR parameter has a percentage value of 43.17% and Throughput with a percentage value of 83.56% while Telkomsel operator have a SINR value with a percentage of 17.58% and throughput with a percentage value of 36.59%.

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

Network interference such as overshoot can affect differences in signal quality and strength on cellular networks. Overshoot is a situation where the network power coverage exceeds the initial planning limit, causing users to be served by cells that are further away than the closest cells. This research aims to deal with problems that arise due to overshoot in the East Sawahan area. The research was conducted using the drivetest method in East Sawahan, Padang. The software used is TEMS Pocket for collecting measurement data and TEMS Discovery software for processing drivetest result data. Network performance is seen from the RSRP, SINR and PCI parameters. In this problem, network performance was improved using Atoll software. With the antenna tilting method which was previously 0? increased to 6?, the improvement results show that after making changes to network performance the signal quality meets the results of the KPI standards.

Abstract

A handover strategy is required to ensure connection continuity for cellular network users due to user mobility. Handovers on the same frequency (intra-frequency) and handovers on other frequencies (inter-frequencies) are conceivable in the Intra Radio Access Technology network. The network must be able to give the best quality and optimal bandwidth so that consumers can keep their connection. Most cells have more than one bandwidth channel. A test was performed in this study to determine the influence of priority handover on intra-frequency LTE handover on signal strength and throughput. This study is based on actual measurement findings from the deployed 4G LTE network transceiver device, which contains several carriers for each eNodeB. TEMS Pocket, a mobile gadget, was used to collect data for measurements. For analysis purposes, the parameters RSRP, throughput, frequency band, serving cell identification or PCI (Physical Cell Identity), and event handover are employed. In the inter-frequency LTE handover, there are two priority handovers: handovers from lower bands to higher bands (high priority) and handovers from higher bands to lower bands (low priority). When a low-priority handover happens, the RSRP value and throughput increase, while a high-priority handover causes the RSRP value to decrease.
