In 2020, "new infrastructure" is announced to be on the windy side, from the central policy to the financial market, without exception, are hot for it. Compared with the traditional infrastructure, new infrastructure is a new upgraded infrastructure based on a series of cutting-edge science and technology.
And in the 7 new infrastructure overall planning mentioned by our country, 5G new infrastructure is undoubtedly more unique, because it is the priority basic of other six new infrastructure, the future will give a solid support point for the operation of the six industries.
The same, in the car networking industry, 5G with bandwidth testing, low latency,gnss module wide connectivity and other features, is generally considered by the field to be one of the most important new technologies to solve the current stage of intelligent transportation problems.
At the "5th i-VISTA International Symposium on Intelligent Networked Vehicles" held in 2022, experts and professors from government departments, associations, research institutes, and other fields such as automotive, communications, and IT focused on "5G Combination - New Green Ecology of Intelligent Networked Vehicles". In the "5G combination - new green ecology of intelligent networking", technical sharing and insights were exchanged.
Then, in the eyes of the industry's authoritative experts, what is the development trend of 5G new infrastructure at this stage, and how will it disrupt the innovative car networking, how should the field view this kind of transformation, and what will be the future development trend of its field?
Policy favorable, the field a glow
In 2018, China held the middle economic meeting, the exchange will be the first time clearly put forward "accelerate 5G commercial footsteps, strengthen artificial intelligence technology, industrial Internet of Things, Internet of Things technology and other new infrastructure", and then in 2019, 5G officially began commercial.
In March 2022, the Ministry of Industry and Information Technology pushed the "Notice on Promoting the Accelerated Development of 5G", stipulating that all departments across the country should make every effort to promote 5G network construction, application promotion, technological advancement and safety precautions while improving the prevention and control of epidemics.
The new national policy aspect gradually correct guidance, each region also strongly support, according to information: since 2020 to date, there have been 8 geographical areas to establish the overall planning of the total number of newly created 5G mobile base stations within the year program, a total of more than 300,000.
On the other hand, the new crown epidemic in 2022 also strengthens the self-confidence of landing type 5G new infrastructure faster, as it seems with the over-the-top visual effect, the landing type of 5G will definitely accelerate the disruptive innovation intelligent transportation, and after that, when dealing with the similar media PR outbreak, self-driving cars will be able to replace people drivers to reach the goal under the risky external environment analysis.
At the i-VISTA intelligent networked vehicle seminar, Ge Yuming, director of the office of the China Academy of Information and Communication Research, indicated that the three Chinese operators have actually opened more than 600,000 5g communication base stations, while there is also a total of more than 15,000 such a basic construction every week, and the number of users connected to the 5g network has reached 1.5 million by now. million.
This shows that the new 5G infrastructure is trending forward with vigor and vigor.
The disruptive innovation of 5G new infrastructure for car network
Theoretically speaking, there are actually two branches of the car network, namely Telematics (vehicle-based data services) and V2X. At this stage, all fields are converging towards V2X, and our current theme style is also the latter one - V2X.
In fact, in our country, we already have the key technical specifications about LTE-V2X such as connection layer, link layer, information layer and security, but there is still one problem that cannot be dealt with since the beginning, that is, the requirement of low latency, high security and reliability needed for vehicle networking.
Wu Hequan, an academician of the Chinese Academy of Engineering, had mentioned in his announcement speech: "In terms of communication, 4G Internet support point L1/L2 level of autonomous driving is fine, but if it does need to L5 level of autonomous driving to 5G. remote control safe driving, autonomous driving regulations end-to-end delay of no more than 5ms, stability regulations to do 99.999%, only 5G can be applied to this provision."
As the fifth generation of wireless transmission technology, 5G relative to 4G, the main performance indicators focus on high-speed transmission, low latency (4G is 100ms, 5G can guarantee 1ms) and wide connectivity three levels, so along with the arrival of 5G, will largely accelerate the commercial landing type of V2X.
On the other hand, the disruptive innovation of 5G on Telematics is also manifested in vehicle-road cooperation. As we all know, at this stage, autonomous driving is divided into two technical solutions, namely bicycle intelligence and vehicle-road cooperation.
And the larger limitation of the previous one stems from the lack of all-round cognition of environmental factors. At the i-VISTA Intelligent Networked Vehicle Seminar, Ge Yuming, director of the office of the China Academy of Information and Communication Research, dissected with real data information: it was found that street intersections, tunnel construction and ramp intersections are the high frequency of safety accident cases, and the direct reason is due to the lack of cognition of environmental factors.
The network-linked platform-type autonomous driving can fill the lack of bicycle intelligence and complete the information exchange between the car and the surrounding people, cars, roads and other traffic participants, so as to improve safe driving, reduce the cost of vehicle-based machinery and equipment, and improve the efficiency of urban traffic operations.
According to an analysis done by the U.S. Department of Transportation based on 6 million road traffic accidents in a particular area, 60% or more of road traffic accidents can be handled based on bicycle intelligence, and 80% of road traffic accidents can be handled using sound V2X vehicle-road cooperation, and the combination of the two can handle about 96% of road traffic accidents.
Therefore, 5G is widely felt to be a core technology point for vehicle-road collaboration, and only with the strong support of low latency in bandwidth testing, vehicle-road-excellent people can complete the said "instant communication".
Naturally, the common application areas of 5G disruptive innovation car networking are not limited to autonomous driving, including AR navigation bar, dangerous driving detection, traffic road navigation bar and other applications, will be led by 5G to complete the qualitative improvement.
How does the field view such development trends
Along with the 5G new infrastructure gathering landing type, car network this definition will also be in this link in the rapid development trend, then the field and how should see this kind of transformation?
The first thing to know, 5G and car network in the middle, still in the exploration of the combination of links, the whole industry chain also belongs to touch the stone to cross the river, many standards norms, the role are also to be sound.
Therefore, it is not easy to carry out the technical certification of 5G Telematics on a large scale, according to the relevant data information: at this stage, there are only about 40 demonstration sites and demonstration stations of intelligent networking in large cities, and about 20 demonstration parks of intelligent highway vehicle-road cooperation.
Therefore, for car manufacturers or dealers, the key point is that they must "follow the facts" and pay close attention to the specifications of 5G Telematics and technology development work, so as to keep up with the rhythm of product development.
On the other hand, before the layout of the entire field is not fixed, users of automotive manufacturers can choose to collaborate with other organizations to explore the commercialization of the landing method or technical market prospects.
The more well-known organizations in the industry, such as the China Automobile Academy Intelligent Network Technology Co., Ltd, have the ability to give full-stack intelligent network solutions, and can give solutions that include V2X + intelligent bus scenarios, V2X + self-driving sanitation garbage truck scenarios, V2X + self-driving electric sightseeing vehicles, V2X + 5G remote control safe driving scenarios, etc.
In addition, according to the i-VISTA intelligent network internet big data cloud service platform, CAC can also give 10 software systems such as V2X safety management system, high-precision map system software, closed field comprehensive operation and maintenance management system, open road inspection and control system software, and vehicle-road cooperative operation and maintenance system.
For car manufacturers and other participants, the car networking field is never a lonely battle, only mutually beneficial win-win situation can complete the runway to highlight the heavy siege.
The future will continue to be good news
As one of the most important landing type scenarios of 5G technology, the future development of Vehicle Networking (V2X) is as promising as the market.
As early as 2017, China created a special committee for the development of the Telematics industry, opened under the National Leading Group for the construction of a strong manufacturing country, consisting of 20 functional departments and enterprises such as the Ministry of Industry and Information Technology, the Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Finance, the Ministry of Public Security, the Ministry of Transport, etc., which undertakes the institutional development of Telematics construction planning, current policies and countermeasures, coordinates the major issues of Telematics industry development resolved, and coordinates the promotion of industrial development.
And before 2019, in China has drawn up national standards and assigned frequency bands, also in January 2022, the Ministry of Industry and Information Technology to establish a statement to speak: C-V2X is the only Telematics standard specification in China.
The following 2020 5G Telematics new infrastructure, and its intelligent car independent innovation development strategic plan was announced, the future 30 years of transportation power to build the overall goal, short, medium and long-term are strong policy support.
On the other hand, internationally C-V2X technical style is also recognized, including Europe, the United States within the announcement of its inclusion in the car networking style, in other words, the world's three largest sales markets, China, Europe and the United States three major scope are identified with the C-V2X specifications and technical nature.
As the current stage of the wind, at the same time is also the next two years is very imaginative indoor space of one of the new technology, 5G process is entrusted by practitioners with high expectations, once the 5G communication base station large-scale completion of the landing style, for the car networking, no doubt in waiting for la "car wind", all areas will also take a big step forward.
On the other hand, as the manager of Zhongguancun Enterprise Engineering Industry Development Co., Ltd. often said in the exchange: "We should not understand the car networking or intelligent collaboration as a single industry chain, it should be understood as an industry management system or industry chain system software". And its treated as a whole industry chain longer, and combined with multiple industry chain management system, occupying a very high proportion in the social economy, from the perspective of China's integrated planning, will eventually continue to vigorously promote the rapid development trend of intelligent networked vehicles.
