On April 23–24, 2026, the Bluetooth Asia 2026 Conference & Exhibition was held in Shenzhen. Lv Jinchao, Product Director of Digital Car Key at YFORE, was invited to attend and delivered a keynote speech titled "Multi‑Node Bluetooth® LE Channel Sounding – High‑Precision Fusion Positioning Based on Phase‑Based Ranging". During the speech, he shared the company‘s latest technological achievements in the Digital Car Key field and announced that YFORE will launch the industry’s first multi‑node Bluetooth® LE Channel Sounding technology solution in the second half of 2026.
This technology integrates two ranging principles – phase‑based ranging and time‑of‑flight (ToF) – delivering three core upgrades:
- Higher Ranging Accuracy: Ranging accuracy reaches ±0.7 meters, significantly outperforming traditional RSSI‑based solutions, with more precise positioning and more stable response.
- Enhanced Security Protection: Using encrypted timestamps to verify actual distance effectively prevents relay attacks, raising the security level comprehensively.
- Better User Experience: It resolves pain points such as unstable unlock upon approach, abnormal lock distance, and the “ping‑pong” false trigger around the vehicle. It remains reliable even in complex interference environments, enabling smoother passive entry.
YFORE continues to drive the upgrade of automotive smart entry through technological innovation. The introduction of multi‑node Bluetooth® LE Channel Sounding will further strengthen YFORE’s technical leadership in the Digital Car Key field, providing automotive OEM customers with safer, more accurate, and smoother smart entry solutions.
