UltraLink 5G DSDA Tbox

Automotive-Grade Dual-Active Link Aggregation for L4 Autonomous Driving

Why Do We Need UltraLink 5G DSDA Tbox?

Cellular network stability is the cornerstone of safety for L4 autonomous driving. However, single-carrier networks are inherently vulnerable to unpredictable coverage gaps. Traditional T-Box solutions face critical bottlenecks that threaten vehicle safety:

  • Single-Module Vulnerability:

    Relying on one carrier creates dangerous single points of failure during critical operations.

  • Unacceptable Latency:

    Legacy dual-SIM setups suffer from prolonged switchover times between Mobile Network Operators (MNOs), failing the strict millisecond-level response requirements of autonomous systems.

The UltraLink 5G DSDA T-Box solves these challenges by utilizing the latest dual-SIM dual-active modules within a strict, automotive-grade hardware architecture. Built on a robust MPU and MCU framework. it delivers uncompromising performance while integrating seamlessly into next-generation vehicle networks.

  • Dual-Active 5G:

    A single, high-performance module supports two carrier networks online simultaneously with zero interruption.

  • Vehicle Networking:

    Features native, high-speed interfaces including CAN, CAN-FD, and Automotive-Grade Ethernet for seamless communication with vehicle domain controllers.

  • Link Aggregation:

    Dynamically bundles data paths to ensure total link redundancy and drastically reduce transmission latency.

  • Intelligent Cloud Routing:

    Leverages a real-time cloud "link quality map" to automatically route telemetry and commands through the optimal signal path.

Key Advantages
