Quality of Service as a Baseline for 5G: A Recent Study of 4G Network Performance in Thailand

摘要

Although the major mobile service providers in Thailand launched 5G services since early 2020, most of mobile users still use 4G services. This paper aims to present the Quality of Service (QoS) parameters obtained from a comparative study of 4G network performance. It has been found that the average download speed increased from 13.97 Mbps in Q2/2019 to 17.78 Mbps in Q2/2020, while the average upload speed increased from 6.25 Mbps in Q2/2019 to 14.59 Mbps in Q2/2020. Furthermore, the average latency decreased from 34.46 ms in Q2/2019 to 28.11 ms in Q2/2020, meanwhile the average jitter reduced from 17.06 ms to 11.91 ms in Q2/2019 and Q2/2020 respectively. Besides, it has been found that the average loss increased from 1.12% in Q2/2019 to 1.94 % in Q2/2019. Thus, these QoS parameters of 4G can be the baseline for the 5G network that will be used widely in Thailand and other countries in the same region in the near future.
