NTT DOCOMO Completes World’s First Outdoor Trial of AI-Driven 6G Wireless Technology
NTT DOCOMO has successfully carried out the world’s first outdoor field trial using real-time transceiver systems equipped with AI-powered wireless interface technology for future 6G networks. Conducted with NTT, Nokia Bell Labs, and SK Telecom, the tests confirmed that AI-enhanced transmission and reception can boost throughput by up to 100% under real outdoor conditions.
The AI-AI wireless interface applies artificial intelligence to both the transmitter and receiver, dynamically optimizing modulation and demodulation based on changing radio conditions. The technology, previously verified indoors, was tested outdoors across three environments in Yokosuka City, including curved roads, areas with partial obstacles, and roads allowing speeds up to 60 km/h.
Across all scenarios, AI integration improved stability and transmission speed. In the most challenging environment—public roads with curves and obstructions—average throughput rose 18%, with peak improvements reaching 100% compared to conventional methods. Additional trials at NTT’s Yokosuka R&D Center showed gains of up to 20% at various speeds, including 60 km/h, under both line-of-sight and non-line-of-sight conditions.
DOCOMO says the results demonstrate the technology’s robustness in real-world environments, marking a major advance toward practical 6G systems that offer higher transmission efficiency and lower power consumption. The company plans to continue testing under more complex conditions, including speeds exceeding 100 km/h, while working with global partners on 6G standardization and deployment.
The AI-driven 6G technology will be showcased at the NTT R&D Forum 2025.
