ShanghaiMay 27, 2026 /PRNewswire/ — In the era of L3/L4 autonomous driving, vehicles are no longer just modes of transportation but intelligent terminals that are continuously online and engage in high-speed interactions. A stable, intelligent, and always-connected channel is becoming the “lifeline” for advanced autonomous driving.
Recently, Jingwei Hengrun’s TBox-P platform, built on Quectel’s automotive-grade 5G-A module AR588MA, has officially entered mass production, providing full-chain support from communication cores to in-vehicle systems for intelligent connected vehicles, accelerating the commercial deployment of advanced autonomous driving. Currently, the Jingwei Hengrun TBox-P platform equipped with the Quectel AR588MA has secured mass production orders from multiple L4-level customers.
Wang Min, General Manager of Quectel’s Automotive Front-End Division and President of Ruiyuan Zhixing, stated: “5G-A is the communication cornerstone for advanced autonomous driving. The AR588MA module pioneers the integration of 5G-A, AI intelligent networking, and automotive-grade security, precisely meeting the core demands of next-generation intelligent vehicles for ultra-large bandwidth, ultra-low latency, and extreme reliability. This collaboration between Quectel and Jingwei Hengrun has created a highly reliable and easily deployable communication solution for advanced autonomous driving.”
Dr. Fan Chengjian, President and CTO of Jingwei Hengrun, said: “Advanced autonomous driving imposes stringent requirements on communication stability, redundancy, and positioning accuracy. The Quectel AR588MA module, with its leading 5G-A capabilities and mature automotive-grade quality, serves as the core support for the TBox-P platform. Through deep collaboration, we have transformed cutting-edge technology into mature, compliant, and reliable engineering solutions, accelerating the commercialization of advanced autonomous driving.”
What kind of confidence does the powerful “core” of the AR588MA bring to the TBox-P platform?
Say Goodbye to Weak Network Anxiety: AI Intelligent Network Selection Lets Vehicles Proactively “Choose Signals”
Underground garages, tunnels, mountainous areas, urban canyons… the network environment in vehicle scenarios is complex and ever-changing. Traditional in-vehicle communication can only “passively wait for signals,” resulting in poor experiences and insufficient stability in weak network conditions.
The AR588MA breaks this dilemma. It features a built-in automotive AI network engine with three core capabilities: scenario recognition, intelligent switching, and signal compensation. It not only perceives vehicle speed, location, and environment in real-time but also autonomously learns base station switching patterns. When a vehicle enters weak signal areas like underground garages, the AI engine pre-judges and dynamically optimizes network selection, paired with an adaptive antenna compensation algorithm, significantly enhancing signal penetration in weak areas, achieving a qualitative leap from “passive connection” to “active optimization.”
5G-A Onboard: Larger Bandwidth, Faster Response, Stronger Capabilities
The AR588MA module is built on the MediaTek 5G-A platform MT2739, compliant with 3GPP R18 standards, with a peak downlink rate of up to 9.0 Gbps and a peak uplink rate exceeding 2.5 Gbps. Compared to traditional 5G, this is not just a doubling of numbers but a leap in experience.
Simply put, under ideal network conditions, downloading an HD movie in the cabin takes just a few seconds, and communication between the vehicle, cloud, and roadside equipment is almost zero-latency. This combination of ultra-large bandwidth and ultra-low latency paves a high-speed data pathway for scenarios like advanced driver assistance and vehicle-to-everything (V2X) communication, making the autonomous driving system faster and safer.
No Single Point of Failure: DSDA Dual SIM Dual Active Creates “Double Insurance”
Advanced autonomous driving cannot rely on a single network. If the communication link is interrupted, the consequences are immeasurable. Ordinary “dual SIM dual standby” only supports parallel standby of two SIM cards, where data on the other card is interrupted during a call. However, the DSDA (Dual SIM Dual Active) feature supported by the AR588MA allows two SIM cards to operate independently and concurrently without interference, truly enabling simultaneous network connectivity.
Even if one operator’s network is congested or a base station fails, the other network can seamlessly take over, ensuring core services like remote monitoring, NG-eCall emergency calls, and vehicle dispatch remain uninterrupted. This true dual-network redundancy builds an unbreakable communication security foundation for L4 autonomous driving.
High Reliability + Easy Compatibility: Rapid Upgrades, Global Availability
The reliability of in-vehicle products directly impacts driving safety. The AR588MA strictly adheres to automotive-grade design standards, meeting AEC-Q100 Grade 2 and ISO 21434 cybersecurity requirements, ensuring stable operation under extreme temperatures (-40°C to +105°C), vibrations, and other harsh conditions. It also supports NG-eCall emergency calls and L1+L5 dual-frequency GNSS high-precision positioning, empowering both vehicle safety and precise navigation.
In terms of upgrade adaptability, the AR588MA adopts a highly compatible design, with hardware pin-to-pin compatibility with Quectel’s automotive 5G series modules and software based on the QuecOpen architecture. Traditional 5G projects can smoothly upgrade to 5G-A without starting from scratch, significantly shortening development cycles and reducing costs. Additionally, the module supports global frequency bands, meeting the mass production needs of automakers in different regions and accelerating global deployment.
In the future, Quectel will anchor the digital foundation of intelligent mobility with high-performance modules and customized solutions, making advanced autonomous driving safer, more reliable, and more accessible.
