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.
As described above, the penetration rate and coverage rate of 5G have already entered the expressway. Also accompanied by a 5G coverage rate, while bringing the high-speed replacement of intelligent products, such as 5G mobile phones, or 5G car whip whip. Obviously, the arrival of the 5G era is no longer the improvement of our simple information dissemination, and it is also a reality that many things that have only existence there is only an imagination. So for cars, the landing of 5G technology will be What kind of personal experience we bring?
I want to reach an unhappy, we must first consider the signal. Transmission issues. For a very simple example, our common mobile maps, inevitable latency when encountering signal unstable regions, resulting in navigation errors, let you go wrong path. To achieve unmanned cars, from a certain level, like a mobile phone that is automatically navigating, you need to continue to stably and quickly signal transmission capability, to make it more accurate to milliseconds, to ensure safety, 5G is the core substrate that guarantees this signal transmission capacity.
5G network is also the fifth generation mobile communication network, and its peak theoretical transmission speed is up to 10GB per second, currently 4G letters can only reach 75Mbps, 5G network transmission speed than 4G networkDeluncy is hundreds of times fast. The highest peak speed mentioned above is laboratory data, which will be relatively low in the actual user, but 5G network will be much faster than the current 4G, and the actual situation may reach hundreds of megabytes per second, or even more than 1G. Another example, before you are in the 4G network, you can download a small movie that reaches 2G, you may need a dozen minutes, and under the 5G network, download a 2G size file, It is only a few seconds. It is also such a powerful transmission capability that 5G technology becomes unhappy hope.
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.
What is the most basic requirement for automotive intelligence ecology? Yes, or 5G technology. As the automatic driving requires efficient and fast information transmission speed, the car intelligent ecology also requires millisecond level information transmission, because the ultimate goal of the vehicle network is to implement real-time operation, such as conference communication, real-time information broadcast, and even video interchange requires adequate The communication foundation, and 5G technology is undoubtedly the best choice.
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.
