In late June, the Ministry of Industry and Information Technology (MIIT) officially approved two industrial standards that establish the first clear regulatory framework for 5G networks in high-level autonomous driving scenarios. The documents, titled "Methods of deploying and testing 5G networks to support high-level autonomous driving" and "Performance requirements of 5G networks to support high-level autonomous driving," are set to become effective on September 1, 2026. This move marks a pivotal moment in setting global benchmarks for telecommunications in the transport sector.
The development of these standards spanned more than three years, with the formal process beginning in March 2023 under the leadership of the Shanghai Communications Administration, the state-owned operator China Mobile, and the China Academy of Information and Communications Technology (CAICT). The initiative involved a broad coalition of over twenty organizations from the public sector, telecommunications industry, and academic circles. This high level of coordination reflects the necessity of synchronizing every link in the chain, from urban road infrastructure to communication safety protocols on high-speed expressways.
Before the introduction of these standards, the industry faced a critical need for unified guidance. The absence of a single benchmark meant there were no clear answers on how to verify 5G network quality under real-world autonomous driving conditions or what specific metrics should be used for coverage planning. This ambiguity led to discrepancies between regional projects, complicated technical debugging, and often caused investment to stall due to regulatory uncertainty.
The newly approved standards fill this gap by establishing comprehensive criteria and methodologies. They cover everything from key performance indicators (KPIs) and testing procedures to specific reliability requirements for communication. Furthermore, the standards address various operational environments, ranging from major urban highways to complex and high-traffic intersections, providing a clear technical target for network engineers.
In Shanghai, where large-scale testing is already in full swing, these standards are expected to act as a significant catalyst for growth. The city has already opened more than 2,700 kilometers of roads for testing purposes, hosting over 900 vehicles from 40 different companies. These vehicles have collectively logged a total test distance exceeding 32 million kilometers. The new rules provide a structured framework for the deployment of Vehicle-to-Everything (V2X) infrastructure, allowing cars to exchange data with road sensors and other vehicles.
A specific 100-kilometer 5G-V2X network is currently being deployed in the Pudong district, and the new national standards will ensure this project remains consistent with broader requirements. This regulatory foundation is essential for commercial pilots and demonstration projects in Shanghai, ensuring they can eventually be integrated into a wider national network without technical friction.
On a national scale, these standards serve to prevent technological fragmentation across different regions. Currently, cities from Beijing to Guangzhou, and Shenzhen to Changsha, are participating in twenty pilot zones dedicated to the integration of "vehicle-road-cloud" systems. Without unified metrics, each region would be forced to solve these complex technical problems in isolation. A single standard allows for the successful replication of experience from one region to another, accelerating the rollout of the Internet of Things (IoT) in transport while reducing overall infrastructure costs.
The philosophy guiding this development is a "dual track" approach that emphasizes the simultaneous improvement of vehicle intelligence and the advancement of connected infrastructure. In this ecosystem, 5G is not merely a data transmission channel but a foundational layer that compensates for the physical limitations of onboard sensors. When a vehicle encounters an object hidden from its cameras or radars, such as a pedestrian behind a parked car, V2X technology relays information from roadside sensors to the car, enhancing reaction speed and overall safety.
Over the long term, these unified standards will facilitate broader commercialization. The history of technology demonstrates that without harmonized requirements, innovations often stall between the laboratory phase and mass implementation. By lowering the costs of network deployment and maintenance while increasing reliability, these standards provide manufacturers and operators with a clear target for their investments. Ultimately, this leads to a more predictable and trustworthy experience for passengers, whether they are using a robotaxi in Beijing or Shanghai, paving the way for large-scale commercial autonomous services.
