  This article compares two of the leading mobile network operators in
Thailand's telecom market in terms of the service quality of Thailand's 5G
networks. The following three factors, download speed, upload speed and
latency, which are frequently considered to be indicators of the quality of
Internet networks, were examined. The researchers employed the test results to
determine an average grade of service that was reached by comparing newly
collected data to data that had previously been examined utilizing the same
format and application in the middle of May 2021. The typical upload speed
dropped from 62.6 Mbps in 2021 to 52.0 Mbps in 2023, while the latency
increased from 14.9 to 23.3 milliseconds on average. It was established that
the results delivered considerably enhanced quality values despite the fact
that the test region in this study only comprised BTS stations. Furthermore,
this was the case despite the fact that the test area in this study only
encompassed a small percentage of the total population.
