In August 2026, Huawei released the engineering specification white paper for the ASN850 ultra-long-range roadside millimeter-wave radar, detailing its technical parameters and deployment standards for smart highway and intelligent traffic management applications. The ASN850 leverages 5G Massive MIMO technology to achieve bidirectional 1000-meter, 10-lane coverage.
White Paper Release: Standardizing Roadside Perception Technology
Huawei has released the ASN850 ultra-long-range roadside millimeter-wave radar engineering specification white paper, providing comprehensive technical disclosure of a radar product already validated across multiple smart highway projects. This publication signals a shift from project-customized deployment to standardized, replicable solutions for roadside mmWave radar technology.
Core Technical Parameters: Kilometer-Scale Perception
The ASN850's key technical advantages lie in its ultra-long-range, high-precision, all-weather perception capabilities:
- Ultra-Long Detection Range: >1000 meters, bidirectional coverage
- Ultra-Wide Lane Coverage: 10-lane full coverage with no blind spots
- Precision Event Detection: 3D joint detection with 95% accuracy
- All-Weather Operation: Strong penetration of rain, snow, and fog; unaffected by lighting conditions
- Simplified Deployment: Precision planning, simplified calibration, self-registration, self-calibration
The radar employs 5G Massive MIMO large-scale antenna arrays and super-resolution algorithms, paired with Huawei's edge intelligent computing fusion perception engine for radar-video fused deployment.
Application Scenarios: From Smart Highways to Urban Traffic Management
ASN800 mmWave radar applications span multiple intelligent transportation domains:
- Smart Expressways: Ultra-long pole-spacing deployment reduces infrastructure costs by over 25%
- Intelligent Traffic Management: All-weather detection and multi-target tracking for complex scenarios
- Vehicle-Road Collaboration: Provides beyond-line-of-sight road condition data for autonomous vehicles
