Among the seven new infrastructure plans put forward by the state, 5G new infrastructure is undoubtedly the most special, because it is the pioneering foundation of the other six new infrastructures and will provide solid support for the operation of the next six fields.
Similarly, in the field of vehicle networking, with the characteristics of high bandwidth, low delay and wide connection, 5G is widely regarded by the industry as one of the most important technologies to solve the current difficulties in intelligent transportation.
At the "5th i-VISTA Intelligent Networked Automobile International Symposium" held this year, experts and scholars from the government, industry associations, scientific research institutions, and automobile, communication, IT and other industries launched technology sharing and exchange of views around "5G convergence, new ecology of Zhilian".
Then, in the eyes of industry experts, what is the current development of new 5G infrastructure, how will it empower the Internet of Vehicles, how should the industry respond to this change, and what will be the future development trend of the industry?

Good policies and bright industries.
In 20 18, the state held a central economic work conference, at which "accelerating? 5G？ The pace of commercialization, strengthening the construction of new infrastructure such as artificial intelligence, industrial Internet and Internet of Things ",followed by 20 19, 5G officially began to be commercialized.
In March of this year, the Ministry of Industry and Information Technology issued "About Promoting? 5G？ The circular on accelerating development requires all localities and units to make full efforts to promote epidemic prevention and control at the same time? 5G？ Network construction, application promotion, technology development and security.
The national policy level began to guide, and all localities also responded positively. According to the data, since 2020, eight regions have clearly planned to build new buildings during the year? 5G？ The total number of base stations exceeds? 30? Ten thousand.
On the other hand, this year's epidemic has also strengthened the confidence to quickly land the new infrastructure of 5G, because from a forward-looking perspective, the landing of 5G is bound to accelerate the empowerment of smart transportation. In the future, when similar public relations and health incidents break out, driverless cars will be able to replace human drivers to complete tasks in a dangerous external environment.
Ge, vice president of China Information and Communication Research Institute, said at the i-VISTA intelligent networked automobile seminar that there are actually more than 600,000 5g base stations opened by three domestic operators, and the number of such constructions exceeds 6.5438+0.5 million per week. Up to now, the number of terminals connected to the 5g network has reached 65.438+0.5 billion.
It can be seen that the new infrastructure of 5G is booming.

5G new infrastructure empowers car networking
Broadly speaking, the Internet of Vehicles actually has two branches, namely Telematics and V2X. At present, the whole industry is in transition to V2X, and our theme today is the latter-V2X. ?
In fact, China already has the core technical standards related to LTE-V2X, such as access layer, network layer, message layer, security, etc., but there is still a problem that cannot be solved all the time, that is, the requirements of low latency and high reliability required by the car networking.
Wu Zeng, an academician of China Academy of Engineering, said in a public speech: "As far as communication is concerned, it is no problem for the 4G network to support L 1/L2 level autopilot, but if L5 level autopilot is really to be realized, it needs 5G. ? Remote driving and automatic driving require an end-to-end delay of less than 5 milliseconds, and the reliability requirement reaches 99.999%. Only 5G can support this requirement. "
As the fifth generation wireless communication technology, compared with 4G, the core technical indicators of 5G are concentrated in three aspects: high speed, low delay (4G is 100 ms, 5G is realizable 1 ms) and wide connection. Therefore, with the arrival of 5G, the commercial landing of V2X will be greatly accelerated.
On the other hand, the empowerment of 5G to the Internet of Vehicles is also reflected in the coordination of vehicles and roads. As we all know, at present, autonomous driving is divided into two technical routes, namely bicycle intelligence and vehicle-road coordination.
The biggest limitation of the former lies in the incomplete perception of the external environment. At the i-VISTA intelligent networked automobile seminar, Ge, vice president of China Institute of Information and Communication, made an analysis with real data: it was found that intersections, tunnels and ramps were places where accidents frequently occurred, and the root cause was insufficient perception of the external environment.
The networked automatic driving can make up for the lack of bicycle intelligence and realize the information exchange between the vehicle and the traffic participants such as people, cars and roads around it, thus improving driving safety, reducing the cost of on-board equipment and improving the operation efficiency of the traffic system.
According to the analysis made by the US Department of Transportation based on their 6 million traffic accidents at a specific stage, about 60% of traffic accidents can be solved by bicycle intelligence, and 80% of traffic accidents can be solved by perfect V2X vehicle-road coordination. The combination of the two can solve about 96% traffic accidents.
Therefore, 5G is generally regarded as a key technical point of vehicle-road coordination. Only with the support of high bandwidth and low delay can the car-road-people realize the so-called "real-time intercommunication".
Of course, the typical application scenarios supporting the 5 G car networking are not limited to autonomous driving, including ar navigation, fatigue driving monitoring, real-time road navigation and other applications, which will all achieve qualitative improvement under the empowerment of 5 G.

How does the industry respond to this trend?
With the gathering of new 5G infrastructure, the concept of car networking will also develop rapidly in this process, so how should the industry respond to this change?
First of all, we must understand that between 5G and the Internet of Vehicles, it is still in the stage of exploration and integration, and the whole industry is still crossing the river by feeling the stones. Many technical standards and functions need to be improved.
Therefore, it is doomed that the technical verification of the 5G car networking will not be carried out on a large scale. According to relevant data, there are only about 40 pilot and demonstration sites of city-level intelligent networking at present. An intelligent road vehicle-road collaborative demonstration area is about 20? A.
Therefore, for OEMs or related suppliers, it is very important to "seek truth from facts" and pay close attention to standards promotion and technology research and development in related fields of 5G vehicle networking to keep up with the pace of research and development.
On the other hand, before the whole industry structure is determined, the players in the OEM can choose to cooperate with other institutions to jointly explore the commercialization model or technical prospects.
Well-known institutions in the industry, such as China Automotive Institute Intelligent Networking Technology Co., Ltd., have the ability to provide full-stack intelligent networking solutions, including V2X+ intelligent bus scene, V2X+ self-driving sanitation vehicle scene, V2X+ self-driving sightseeing bus scene and V2X+5G remote driving scene.
In addition, based on the data cloud platform of i-VISTA intelligent network, CAFC can also provide 10 application systems such as V2X security system, high-precision map system, closed yard integrated operation management system, open road test supervision system and vehicle-road collaborative operation and maintenance system.
For OEMs and other participants, the car networking industry has never been alone. Only by complementing each other's advantages can we achieve a breakthrough on the track.

It will continue in the future. okay
As one of the most important landing scenarios of 5G technology, the future development of the Internet of Vehicles (V2X) is also promising.
As early as 20 17, China set up a special Committee for the development of the car networking industry, which was established under the leading group of the national construction and manufacturing power, and was composed of the Ministry of Industry and Information Technology, the National Development and Reform Commission and the Ministry of Science and Technology? Twenty departments and units, including the Ministry of Finance, the Ministry of Public Security and the Ministry of Transport, are responsible for organizing the formulation of development plans, policies and measures for the Internet of Vehicles, and coordinating and solving the Internet of Vehicles? Major issues in industrial development, promote the overall development of the industry.
Before 20 19, China had formulated the national standard and allocated the frequency spectrum, and in June this year, the Ministry of Industry and Information Technology made it clear that C-V2X was the only technical standard for vehicle networking in China.
Next, in 2020, the new infrastructure of 5G car networking and the innovative development strategy of smart cars will be released. The construction goal of a transportation power in the next 30 years will have strong policy support in the short, medium and long term.
On the other hand, the technical standard of C-V2X is also internationally recognized, including Europe and America, which have announced that it will be included in the vehicle networking standard. In other words, the three largest markets in the world and the three major regions in China, Europe and America all recognize the standards and technologies of C-V2X.
Write at the end:
As the current outlet and one of the most imaginative technologies in the next few years, 5G technology has always been highly anticipated by practitioners. Once the 5G base station is built and landed in a large area, it will undoubtedly wait for the "Dongfeng" of the Internet of Vehicles, and the whole industry will also take a big step forward.
On the other hand, as Wang Lu, general manager of Zhongguancun Enterprise Engineering Industry Development Co., Ltd. said at the conference, "We should not understand the Internet of Vehicles or intelligent collaboration as a single industry, but should define it as an industrial system or industrial system". As a system with a long industrial chain and integrating various industries, it occupies a fairly high proportion in the national economy. Judging from the national top-level design, it will continue to vigorously promote the rapid development of intelligent networked vehicles.
