5G Network Performance: A Study using Stationary and Mobility Tests on Sukhumvit Line – BTS Skytrain in Bangkok

This paper presents a study of 5G efficientcy using field tests, covering both stationary and mobility tests, to investigate the performance of 5G networks that are deployed nationwide in Thailand. In this study the longest and busiest route of the BTS Skytrain in the heart of Bangkok was selected. Then, the data were collected using the Speedtest application and a 5G smartphone with 2 SIM cards provided by two major mobile service providers. After the analysis, it has been found that the download speeds from the stationary test was 297.5 Mbps and the upload speed was 71.2 Mbps, while the download and upload speeds from the mobility tests were 273.0 Mbps and 48.8 Mbps respectively. However, after using t-test technique for analysis, it has been found that the upload speed from the mobility tests is significantly lower than the speed from the stationary tests (p-value < 0.001). This means that mobility impacts 5G speeds. In conclusion, the overall download speed in Bangkok was 289.6 Mbps and the overall upload speed was 64.0 Mbps. The result from this study can be the new baseline for 5G deployment in other areas of Thailand.
