According to the relevant data related to the three major operators, the 5G end users in China have exceeded 200 million, 5G smartphone shipments exceeded 1.63 billion, and the 5G base station has built more than 700,000, the world’s largest scale. . It is estimated that the three major operators in 2020 exceeded RMB 180 billion (about $ 27.8 billion), accounting for about 53% of the annual capital expenditure. With the further construction of 5G base station, the growth of 5G mobile phone will appear in nearly 2nd to 3 years.
Moreover, with the current car intelligent development direction, the direction of the car intelligent is not only in automatic driving, but also Remote driving is required to achieve a further intelligent travel. Whether remote driving or automatic driving, the delay of the end is not more than 5 milliseconds, the reliability is 99.999%, and the data per car will reach 1GB. According to the requirements of mobile communication standardization, 3GPP requirements for EV2X (enhanced V2X communication), the requirements of automatic driving and sensor sharing, the delay cannot be higher than 3 milliseconds, and the sensor shares requires bandwidth 1GB. The 4G era, the delay of the LTE is about 100 milliseconds, and the edge calculation can be reduced to 10 milliseconds, but still exceeds the current automatic driving requirements. So only 5G + edge calculations can realize the basic information needs of automatic driving.
After saying that no one is driving, it is necessary to say that 5G technology is bonded to the other side of the car intelligence – the network. It is now not difficult to find that the guides of the car enterprise for automobiles are not only driving, but also to build a smart ecosystem. The media of this ecosystem is a car, more straightforward, hoping that the car can become the second part of human beings. ” Smartphone “, all applications of life through car intelligence can be used in series, small to various living homes, and pay for payment transactions, and even work, they can be completed in a smart car, and this It is the car intelligence ecology that the car is trying to bring. Now you can see the internet of the car enterprises promoted by the car enterprise, which is a routine action in this area.
Obviously, 5G technology is undoubtedly its core basis for automotive intelligence. But when it comes back, 5G technology is a necessary condition for automatic driving and car nets, but if you want to fully meet the vehicle intelligence needs, 5G technology has a lot of difficulties need to overcome. First, 5G is designed for public communication, and the public communication is in the room, in non-moving state; 80% of the vehicle network is in the driving state, which is higher. In addition, public communication only occupies channels, mainly to point to point communication; and the network is basically online, communication is point-to-multipoint and multi-point, 5G era network slice can be prestressed enough And meticulous is a problem. In other words, 5G can break through the technical difficulties of long-term mobile communications, will be a gate opening of the vehicle intelligence technology breakthrough.
For the automotive industry, with the addition of 5G technology, the past The imagination of car intelligence is also expected to become reality. However, for 5G technology itself, although it gives us hope, but the same, today’s 5G technology is mainly mobile network, so it will form a certain conflict with the application characteristics of the car in applicability, and when After this layer of conflict is unlocked, the car intelligence will truly enter the fast lane.
