Abstract

The growth of cellular telephone subscribers experienced a significant increase compared to other industries. With large and widespread number of subscribers, many operators have established new Base Transceiver Stations (BTS) to keep up with the increase number of subscribers. However, the addition of BTS is not a total solution to offset the increase number of subscribers. The purpose of this study is to analyze the signal quality, coverage area and network repairs by using physical tuning method. In Telkomsel operator drive test data in Minangkabau International Airport area, the RSRP parameter obtained an average sample data area around the site in the range -110 to 0, with a red indicator of 3.35%, an orange indicator of 18.96% and a yellow indicator amounted 36.3%. In this way, this research optimizes physical tuning method, including Re-azimuth which successfully directs the antenna to the badspot area, then changes the height of the antenna which makes it covered farther and tilting the Antenna which succeeds in making the coverage area more optimal. For the next bad spot area, optimization should be done in real time in the field so that the improvement can be resolved properly.

Abstract

The implementation of Carrier Aggregation makes it possible to expand spectrum use by combining several bandwidth channels that work like a single spectrum. The LTE network is deployed on several bandwidth channels, namely 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz and 20MHz. Each bandwidth channel that is correlated with the implementation of carrier aggregation will occupy a different and non-adjacent frequency band, namely 900MHz, 1800MHz, 2100MHz and 2300MHz. In this research, we tested the effect of a combination of CAs that occupy non-adjacent frequency bands on uplink and downlink performance. Measuring and analyzing network performance to determine throughput using several supporting software, namely Tems Investigation, Tems Discovery and Gnet Track. There was an increase in the downlink throughput and uplink throughput values due to the implementation of CA compared to not using CA. The maximum Downlink Throughput value in the CA combination is greater than the Uplink Throughput. The maximum Downlink throughput value on CA 20+20Mhz is 9427kbps, while the Uplink value is 1133.28kbps. The maximum downlink throughput value on CA 20+15Mhz is 8272.24kbps, and the maximum uplink throughput value is 745kbps.

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

The advancement of cellular telecommunications is growing day by day. Some theories, including 4G LTE FDD 1800 MHz, are becoming irrelevant to the current technology. The theory of power reduction by the cell splitting method is unsuitable for the actual condi-tions in the field. Theoretically, the cell splitting method is carried out on a new site with half of the main site's coverage, in which the transmitter power at the split site is reduced by 12 dB from the main site. This results in the power generated from the calculation be-ing small so that service coverage is limited. This study aimed to test the theory of trans-mitter power reduction in the cell splitting method (scenario 1) and compare it with other power reduction scenarios (Scenario 1: reduced by 15 dB, and Scenario 2: reduced by half from the main site power). The analysis is done by conducting simulations using Atoll RF Planning software. The study results revealed that in Scenario 3, the value of Key Perfor-mance Indicators is better than in other scenarios. The average throughput is 11045 kbps, the RSRP value is -108.58dBm, the range is 1.045 Km, and the average SINR is reduced to 8.52 dB. In addition, the data revealed that the coverage and signal quality of the site cell splitting is better when the transmitter power is 43 dBm (scenario 3). In conclusion, a site with higher transmitter power tends to have better signal strength, quality, and speed, as well as a wider coverage area. Reducing the transmitter cell splitting power will be more effective by reducing the new power site to half of the main site.

Abstract

This research discusses the comparison of Quality of Service (QoS) performance on 4G LTE and 5G networks in the Bekescsaba region, Hungary. The analysis was conducted based on five main QoS parameters, namely download speed, upload speed, jitter, packet loss, and latency, with the RSRP (Reference Signal Received Power) measurement category. The results showed that 5G networks consistently outperformed 4G LTE in almost all categories. For example, in the Very Good category, 5G networks recorded download speeds of up to 196 Mbps, upload speeds of 91.5 Mbps, and latency of 25 ms, significantly better than 4G LTE. In the Good and Fair categories, the 5G network continued to show significant advantages in data speed and latency, although the jitter values were relatively comparable to 4G LTE. In addition, packet loss on both networks was recorded at 0%, indicating a high level of reliability. This study concludes that 5G networks provide a better experience in supporting modern connectivity needs than 4G LTE, even under less than optimal signal conditions. The findings are expected to serve as a reference for future telecommunications infrastructure development.

Abstract

This study evaluates the deployment of 5G New Radio (NR) Non-Standalone (NSA) operating on Frequency Range 1 (FR1) Sub-6 GHz in Bukittinggi, Indonesia. Field measurements were conducted using drive test methods to assess key performance indicators, including RSRP, RSRQ, SINR, and throughput. The results show that all measured RSRP values exceed –95 dBm, indicating good signal coverage across the test area. Approximately 71% of SINR samples are above 0 dB and 80% of RSRQ values exceed –17 dB, reflecting relatively stable channel conditions. However, 77% of throughput measurements remain below 10 Mbps, suggesting that achievable data rates remain moderate despite good signal quality. The analysis indicates that SINR has a stronger impact on throughput compared to RSRP and RSRQ. Although 5G NR NSA demonstrates superior signal quality compared to LTE, 4G LTE achieves higher data speeds at the measurement location. These findings highlight the influence of NSA architecture, bandwidth limitations in FR1 Sub-6 GHz, and network optimization factors on overall 5G performance.

Abstract

Enhanced Mobile Broadband (eMBB) adalah salah satu skenario utama dalam implementasi jaringan 5G New Radio (5G NR), yang dirancang untuk mendukung kebutuhan komunikasi data berkecepatan tinggi dan kapasitas besar. Layanan eMBB membutuhkan dua parameter utama untuk menjamin kualitas layanan, yaitu throughput yang tinggi dan latency yang rendah. Penelitian ini bertujuan untuk menganalisis dan mengkaji faktor-faktor yang memengaruhi throughput dan latency pada jaringan 5G NR untuk layanan eMBB melalui studi literatur. Metode yang digunakan adalah studi literatur deskriptif-komparatif dengan mengumpulkan dan menganalisis berbagai referensi ilmiah yang relevan mengenai performansi jaringan 5G NR. Hasil studi menunjukkan bahwa throughput pada jaringan 5G NR dipengaruhi oleh bandwidth, modulasi, teknologi MIMO, dan kondisi kanal radio, sementara latency dipengaruhi oleh arsitektur jaringan, penjadwalan radio, serta kepadatan trafik. Penelitian ini juga menemukan bahwa implementasi 5G NR pada layanan eMBB dapat menyediakan peningkatan kinerja yang signifikan, meskipun faktor eksternal seperti interferensi dan kualitas sinyal dapat mempengaruhi performansi aktual. Penelitian ini memberikan wawasan penting bagi pengembangan jaringan 5G untuk mendukung layanan eMBB yang lebih optimal.

Abstract

Telkomsel has introduced 5G technology in Padang City, evaluated through drive tests using G-Nettrack Pro software to measure Reference Signal Received Power (RSRP) and Signal to Interference plus Noise Ratio (SINR). The tests revealed RSRP values ranging from -44 dBm to -100 dBm and SINR values between -12 dB and 26 dB. While high RSRP does not always guarantee high throughput, higher SINR consistently improves throughput, with the highest throughput reaching 153,053 kbps at SINR levels between 10 and 30 dB. Modulation and Carrier Aggregation (CA) also play a significant role, with 64-QAM modulation combined with CA achieving throughput up to 31,500 kbps, compared to 6,300 kbps without CA. Although CA bandwidth decreased from 100 MHz to 50 MHz, throughput remains higher compared to 20 MHz bandwidth without CA. CA proves highly effective in enhancing throughput through larger bandwidth and more efficient modulation. Additional factors such as handover, interference, and physical and weather conditions also impact network performance. Overall, Telkomsel’s 5G network in Padang City meets the company’s Key Performance Indicators (KPI), despite some areas with suboptimal signal quality.
