4G LTE Network Performance along Mass Rapid Transit (MRT) Putrajaya Line Track

Abstract

With advancements in mobile communication technologies, including the deployment of 4G LTE networks, end-users now expect consistent, high-quality and seamless connections during their commutes on public transit. Due to the high demands placed on cellular networks, users often experience abrupt and unexpected changes in connection quality. These fluctuations in 4G LTE performance need to be anticipated and mitigated to maintain a constant and reliable connection. Therefore, this study focuses on constructing a dataset of 4G LTE network performance, including information on Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ). This data is collected along the Mass Rapid Transit (MRT) Putrajaya Line Railway Track using the Android network monitoring application, G-Net Track Pro. Subsequently, based on these network parameters, the Quality of Service (QoS) is analyzed by measuring download speed, upload speed, latency, jitter and throughput using nPerf SpeedTest software. The analysis of the data and discussion on the signal strength are presented, and various 4G LTE issues along the test route are identified. Since the measurements have not yet met the standards specified by the 3GPP standard, this project also discusses recommendations for network operators to enhance network performance along the route. With the dataset prepared and measurement results provided in this project, telco operators and researchers in Malaysia can benefit from future LTE deployments along the railway track.
