UltraLink 5G DSDA Router

Dual-Active Link Aggregation for Ultra-Reliable L4 Autonomous Driving

Why Do We Need UltraLink 5G DSDA Router ?

Cellular network stability is mission-critical for L4 autonomous driving. However, single-carrier networks often suffer from unpredictable coverage blind spots. Existing T-Box solutions in the industry fall short due to critical drawbacks:

  • Single-Module Vulnerability:

    Traditional single-SIM setups are entirely dependent on one carrier's network health, creating dangerous single points of failure.

  • Unacceptable Latency:

    Legacy dual-SIM solutions experience prolonged switchover times between Mobile Network Operators (MNOs), failing to meet the strict millisecond-level response requirements of L4 autonomy.

The UltraLink 5G DSDA Router is equipped with dual 5G communication modules, enabling rapid adaptation to the in-vehicle environment and seamless integration with domain controllers to completely eliminate these connectivity gaps.

Function  Highlights

  • Dual-Active Connectivity:

    Supports two carrier networks online simultaneously without interruption.

  • Link Aggregation:

    Dynamically merges data paths to guarantee total link redundancy and drastically reduce transmission latency.

  • Cloud-Powered Routing:

    Leverages a real-time AI network quality map to intelligently select the optimal route based on live signal health.

Key Advantages

  • Zero-Interruption Stability:

    Ensures unbroken, millisecond-level data transmission for mission-critical L4 services, aligning with stringent automotive functional safety demands.

  • Predictive Smart Routing:

    Utilizes intelligent, AI-driven insights to proactively route to the best-performing MNO, anticipating and bypassing weak coverage areas before degradation occurs.

  • Optimized Cost-Efficiency:

    Delivers enterprise-grade, high-availability redundancy at a highly competitive total cost of ownership (TCO) compared to legacy multi-device hardware architectures.
