The global commercial vehicle industry is accelerating its transformation toward wireless connectivity, intelligence, and enhanced safety. However, heavy-duty trucks, coaches, buses, and construction vehicles still grapple with key challenges in 360° surround-view systems, including large blind-spot areas, complex wiring, high maintenance costs, and unstable video transmission. Traditional LVDS/coaxial wired solutions suffer from bulky cabling, poor vibration resistance, high failure rates, and difficulties in trailer deployment, making them increasingly ill-suited to the intelligent upgrade requirements of commercial vehicles. Today, the next-generation short-range wireless communication standard led by China—NearLink (also known as SparkLink)—is fundamentally reshaping the technological landscape of the commercial vehicle electronics sector. As an authorized distributor of Beijing Sylincom Technology, BONCHIP offers the company’s full portfolio of NearLink chips and modules, helping the industry achieve a seamless transition to wireless connectivity.
NearLink (officially named NearLink in English, commonly referred to as SparkLink) is a short-range wireless communication standard independently developed in China and recognized by the International Telecommunication Union (ITU). It significantly outperforms Bluetooth and Wi‑Fi in terms of low latency, high reliability, precise synchronization, and strong anti-interference capabilities, and is specifically designed for applications such as automotive and industrial environments.
StarFlash defines two core operating modes to precisely match diverse application requirements:
SLB (Synchronous Low-Latency Broadband) Mode: Designed for high-speed video, large data volumes, and real-time transmission scenarios, it is the optimal solution for commercial vehicle 360° surround-view systems.
SLE (Synchronous Low-Power) Mode: Designed for low-power IoT, sensor networks, and control links, it can be extended to support multi-sensor coordination in commercial vehicles.
Notably, Star-Link has been designated as the sole wireless communication standard within China’s 360° surround-view industry standard for commercial vehicles, marking a historic breakthrough for Chinese wireless technology in the global transportation sector.
Beijing Sylincom Technology is a core member of the Starlink Alliance and a leading R&D company specializing in Starlink baseband chips and communication modules. Leveraging its deep technical expertise, the company has launched a range of high-reliability Starlink products tailored for commercial vehicle applications. As the global authorized distributor of Zhongke Jingshang, BONCHIP provides comprehensive supply of the company’s entire Xingshan product portfolio, offering customers one-stop procurement and technical support services. Core products include:
Integrates SLB baseband, RF components, and a DSP core independently developed by Zhongke Jingshang. Specifically designed for in-vehicle HD video transmission, it boasts significant advantages in key performance parameters:
With bandwidth up to 1.2 Gbps, it supports synchronous transmission of eight channels of 1080p video at 30fps without compression, meeting the multi-camera surround-view requirements of commercial vehicles.
End-to-end latency is less than 20 ms, with synchronization accuracy within ±1 μs, ensuring seamless multi-camera video stitching without stuttering or misalignment.
Industrial-grade standard, supporting operation over a wide temperature range of -40°C to 85°C, with exceptional resistance to vibration and electromagnetic interference (EMI).
Package: 13 × 13 × 1mm FCCSP; rich interface options (PCIe, USB, UART, SPI) for easy integration with in-vehicle ECUs and cameras.
Developed based on the Zhongke Jingshang DX-T600 chip and packaged in mini-PCIe form factor, this module features plug-and-play functionality, enabling rapid integration into commercial vehicle cameras, ECUs, and other devices. Operating in the 5GHz band and meeting industrial-grade wide-temperature requirements, it is suitable for both new-vehicle mass production and cost-effective retrofitting of older commercial vehicles, significantly reducing upgrade costs.
Leveraging automotive-grade reliability, deterministic low latency, and exceptional anti-interference performance, the Zhongke Jingshang StarFlash chips and modules have become the preferred solution for mainstream Chinese commercial vehicle OEMs and ADAS suppliers.
Commercial vehicles (trucks, buses, semi-trailers, construction machinery, etc.) are characterized by their large vehicle bodies, extensive blind spots (up to 70 square meters), harsh operating conditions (severe vibration, wide temperature fluctuations, and exposure to dust, mud, and water), and frequent trailer detachment and reattachment. These unique attributes make it difficult for traditional wired solutions to meet the demands. However, the core advantages of the StarFlash SLB mode precisely address these pain points:
By completely eliminating traditional LVDS cable harnesses and connectors, the camera can be flexibly mounted anywhere on the vehicle—on the body, roof, trailer, or other locations—without the need for complex wiring. This reduces installation time by 90% and cable-harness costs by 80%, while also cutting vehicle weight by approximately 60%, thereby balancing cost efficiency with lightweighting requirements. Especially in trailer-handling scenarios, wireless HD video transmission is enabled between the tractor and the trailer. This eliminates the need to repeatedly connect and disconnect wiring harnesses during drop-and-hook operations, allowing for “plug-and-play” functionality and significantly improving operational efficiency in high-frequency drop-and-hook environments such as logistics parks and ports.
End-to-end latency is less than 20 ms, significantly outperforming the 300ms typical of traditional wired systems. This enables drivers to obtain a real-time 360° bird’s-eye view, providing precise visual cues for maneuvers such as reversing and turning. Multi-camera synchronization accuracy within ±1 μs ensures seamless stitching of 6 to 8 high-definition video streams, completely eliminating image misalignment and ghosting. Meanwhile, with a Polar-code-based anti-interference design, the bit error rate remains below 10⁻⁷ even in challenging environments such as tunnels, charging stations, and areas with high electromagnetic interference, delivering transmission stability that significantly exceeds industry standards.
All StarFusion products from Zhongke Jingshang meet industrial-grade wide-temperature requirements (-40°C to +85°C), enabling them to withstand severe weather conditions such as heavy rain, blizzards, dust, and intense vibration. They completely eliminate failure issues caused by loose connectors and corrosion common in traditional wired solutions, reducing equipment failure rates by more than 90% and lowering operation and maintenance costs by 70%.
Real-time 360° panoramic view completely eliminates blind spots in commercial vehicles. It can also be integrated with ADAS radar and ultrasonic sensors to enable intelligent functions such as pedestrian/vehicle detection in blind zones, collision warning, and automatic switching of the view during turns. This system can reduce blind-spot-related accidents in commercial vehicles by 80%, making it particularly suitable for high-safety-critical applications like public buses and hazardous-material transport vehicles, and it complies with the safety regulations set forth by the Ministry of Transport.
2025: The “Technical Requirements and Test Methods for Panoramic Surround-View Systems for Commercial Vehicles” has officially been adopted as an industry standard by the Ministry of Transport. This is the world’s first wireless surround-view industry standard, specifying Star-Link as the sole designated wireless communication solution.
2026: Leading commercial vehicle OEMs such as Yutong, King Long, FAW, and Dongfeng will begin mass-producing new-energy buses and heavy-duty trucks equipped with the Xingshan 360° surround-view system, marking the entry of Xingshan technology into the large-scale vehicle integration phase.
