AiTrax Successfully Demonstrates Real-time Video Transmission from Moving Large Component Transport Vehicles

AiTrax (Headquarters: Kamakura, Kanagawa; CEO: Tsutomu Tamura; hereafter "AiTrax") successfully conducted real-time video transmission using Wi-Fi access points mounted on large component transport vehicles at the Namura Shipbuilding Imari Shipyard in Saga Prefecture from March 16 to 18, 2026. The system maintained continuous communication without perceptible video interruption, even under challenging conditions where access points switched sequentially while the vehicle was in motion, confirming the technology's readiness for real-world operations.

Due to restrictions in the active factory, equipment installation was limited to narrow windows between production processes. Given that the payloads were massive shipbuilding components weighing tens of tons, the installation of access points and network cameras was restricted to the inner-front exterior of the vehicle, raising concerns that antenna radiation characteristics would not be fully utilized. Furthermore, the demonstration took place under extremely difficult conditions where metal payloads caused dynamic radio signal blocking and reflections. Achieving stable video transmission despite these constraints demonstrates the effectiveness of AiTrax's know-how in antenna selection and firmware parameter optimization, accumulated over three years of research and development.

This outcome is the culmination of a three-year national project funded by the FY2023 New Energy and Industrial Technology Development Organization (NEDO) SBIR Promotion Program and the FY2024-2025 Ministry of Land, Infrastructure, Transport and Tourism (MLIT) Transport Technology Development Promotion System. Unlike conventional products that rely solely on signal strength, AiTrax's proprietary "Path Cost-Based On-Demand Algorithm" calculates path costs in real-time, integrating throughput, latency, and packet loss rates, to autonomously select the optimal path across the entire network. This mechanism enabled millisecond-level path switching and stable video transmission throughout the factory premises (approx. 1,200 meters in total length). Namura Information System participated in this demonstration, confirming concrete intentions to utilize this technology for future vehicle positioning and information coordination between cranes and the ground.
