This study presents the implementation and performance evaluation of a commercial 5G NSA-based wireless communication system for autonomous mobile robots (AMRs) in smart manufacturing environments. A testbed was established using 3.5 GHz NSA networks, industrial 5G routers, and AMRs operating under real factory conditions. Key performance metrics such as latency, jitter, and throughput were measured repeatedly and evaluated against industrial communication standards, including 3GPP TR 22.804. The results showed an average latency of 24.6 ms and jitter of 1.1 ms, with both upload and download speeds exceeding the required thresholds. These findings demonstrate that commercial 5G NSA infrastructure is suitable for AMR-based process automation and real-time monitoring. However, the NSA architecture is limited in supporting ultra-low latency applications (1–10 ms), which are crucial for high-precision control and synchronized operations. Future studies will focus on 5G Standalone (SA) and private network environments to overcome these constraints and enhance wireless performance for industrial robotics.
