Anotācija: 5G Standalone (SA) networks are the next generation of cellular networks, with broad applications envisioned in domains including IoT. In this article, we evaluate the feasibility of using Precision Time Protocol (PTP) to tightly synchronize User Equipment (UE) devices connected to a private 5G SA network. Our goal is to achieve sub-millisecond time synchronization accuracy in order to make the system applicable for industrial-automation IoT networks with stringent timing requirements. We measure the network delay and clock synchronization accuracy through clock comparison utilizing the pulse-per-second output from a UE network card and conclude that the desired accuracy remains challenging, with typical experiments demonstrating multi-millisecond clock offsets with significant and unpredictable drift.
