This paper presents a speed testing platform designed to evaluate Thailand’s Internet broadband network experience. The platform measures internet speed at the ONT (Optical network terminal) as a signal source for the operator (or ISP) and the connected internet device at the user’s accommodation (fixed broadband internet). Scenario tests were conducted involving four major broadband network operators in Thailand, with our application collecting data from 30 devised-based operators and 200 internet users, resulting in a dataset of 25,000 records. The primary focus of our study was on assessing download and upload speeds, as well as latency. The proposed system was deployed in 8 provinces east of Thailand over two months. Results indicate that the Download Percentage Average (DPA) was 64.30%, while the Upload Percentage Average (UPA) was 71.84%. The average ping and jitter were 11.82 ms and 16.53 ms, respectively. Analysis revealed variations in average speed and latency values across different areas and period times, underscoring the efficacy of our system. Our proposed platform could serve NBTC as a central platform for evaluating future broadband internet services in Thailand.
