Wireless two-way interferometry (Wi-Wi) is considered useful as a means of time synchronization in some communication systems. We manually measured the time-synchronization offset between the Wi-Wi module.
In this paper, we evaluated the offset by automating the measurement process and increasing the number of measurements from 100 to 1000 to improve the statistical reliability of the offset. The results showed that there was no significant difference in offset when the offset was evaluated at 100 times and at 1000 times.
This result indicated that the results of previous evaluations have become more reliable.
