Abstract (in Japanese) (See Japanese page) 
(in English) Precise time synchronization is becoming increasingly important in distributed systems and IoT devices that aim for higher efficiency and lower power consumption.
In environments where wired connections are difficult to implement, highly accurate time synchronization via wireless communication is required.
Wireless two-way interferometry (Wi-Wi) is a promising technique that achieves accurate time synchronization via two-way communication.
We have previously evaluated the synchronization accuracy of Wi-Wi.
In this paper we automate the measurement process of time synchronization offsets.
This automation enables a significant increase in the number of measurements and allows evaluation under stable wireless conditions.
As a result, we provide a more reliable fundamental assessment of Wi-Wi's synchronization accuracy, offering useful data for future applications.
