5G and the Internet of Vehicles (1)
Why connect the car to the Internet?
When it comes to the Internet of Vehicles, as the name suggests, it is to let the Internet of Vehicles connect to the Internet. Now air transportation and railway transportation are separate systems. The transportation speed has formed a strong transportation capacity due to the efficient and unified transportation organization. Only vehicle transportation relying on highways and urban roads is not a system. Originally, the speed of automobile movement is slower than that of high-speed rail and airplanes, and the efficiency of road transportation and urban road transportation will naturally fail to improve. Congestion is the norm, traffic accidents are the norm, and the ineffective transportation of empty vehicles is also the norm.
Therefore, we need to let the cars running on the road also have a powerful system to direct them to travel more rhythmically like planes and trains, improve safety, improve efficiency, and increase the proportion of effective transportation. This can not only rely on road drivers to make decisions and requires a "strongest brain" - 5G Internet of Vehicles.
With the Internet of Vehicles, the car becomes an armored command cabin in seconds. Have you ever thought about it? In the past, the road condition information was not directly reflected to the driver but was first collected by the road coil through the Public Security Traffic Administration, then turned into an artificial image, and then transmitted to the radio station, and finally transmitted to the car by the radio station. The driver also needs to listen and drive while thinking. And, most annoyingly, road conditions aren't real-time. With 4G network, various map navigation can also transmit road condition information, but it is still not real-time and inaccurate. Sometimes the car is driving to a congested place, and the road conditions only show that the congestion is congested.
The 5G Internet of Vehicles makes all the lag information that has come and gone disappear, and the car becomes the command cabin in seconds. Let's see what black technology they have.
Car's black technology 1: real-time road traffic information decision.
The speed of 5G Internet of Vehicles is extremely fast, which is less than one thousandth of a second, and 100 times faster than the speed of human blinking. Coupled with the high-speed setting of 5G, the Internet of Vehicles can transmit the real-time position, direction, speed and acceleration of each vehicle to the bypass facility, and then realize the high-speed calculation of vehicle information at an extremely fast speed. According to estimates, this computing density is equivalent to a data exchange every 5-10cm when the vehicle is traveling at 120km/h. If the speed is 60km/h, the vehicle can perform data interaction every 3-5cm. This enables the moving trajectory of the vehicle to be grasped almost in real time, which can also provide a basis for real-time decision-making of road information.
When the traffic flow on a road or even a lane becomes denser, the base station can make this information known to the road system vehicles of 1 square kilometer or even dozens of square kilometers of the surrounding road almost at the same time as the congestion occurs. After that, each vehicle will calculate the optimal path and share the path information in real-time.
At the other end of the roadside facility connection, the computing center, or the cloud, will arrange the optimal path and the best signal light strip status in real-time according to road conditions, and send it back to every vehicle and every vehicle driver through the roadside facility. Before the driver even has time to make a decision, the vehicle has already found the best driving path within 10 seconds or even 1 second. At this time, whether it is a human driving or a vehicle driving automatically, it can rely on the information to make decisions to the greatest extent and take correct actions.
