Comprehensive Performance Evaluation of Mobile Networks in Macao Based on Field Test Data

In this paper, we evaluate the 4G mobile network performance of network carriers in Macao by conducting three types of experiments: drive test, speed test, and application test, collecting field test data. The data is categorized into the objective network performance metrics such as RSRQ, CINR, RSSI, and RSRP, and the subjective metrics such as video freezing time and the perceived delay when using several popular applications. Based on the data, we conducted an evaluation. The result showed that good objective metrics may not necessarily generate good subjective metrics for the overall user experience on mobile applications, if the network coverage is not ideal. In this paper, we introduced max-min average normalization to subjective metrics such that the quantification of multi-type data becomes realistic.
