Since the 5G license was issued in 2019, for a time, 5G-related news was everywhere, making 2019 the first year of 5G. Of course, as the 5G commercial layout accelerates, more people are beginning to care about what 5G can do. What will 5G bring to life? What can 5G subvert? In this post, we will specifically be analysis and explaining 5g and its significance to autonomous driving.
What Does 5G Network mean in a Nutshell?
Summarily, 5G simply means that mobile devices have higher bandwidth and lower latency. Although 5G has very good achievements in smart homes, the key to 5G is wireless connectivity.
In the home and workplace, high bandwidth and low latency can be achieved through an optical fiber. So at present, the most important value of 5G should be telemedicine and connected cars.
Autonomous Driving and Artificial Intelligence: What is “Internet of Vehicles”
Speaking of vehicles and intelligence, of course, one cannot but mention Tesla and NIO Weilai. For apparent reasons, many people like to compare these two car companies with traditional car companies, whether it is power, quality, or driving experience.
Here we first take a look at what is the traditional Internet connectivity of Vehicles: “The Internet of Vehicles concept is derived from the Internet. The Internet of Vehicles is based on the in-vehicle network connections and the mobile Internet.
According to the agreed communication protocol and data interaction standards, “internet of vehicles” is a large system network for wireless communication and information exchange between vehicles-X (X: cars, roads, pedestrians, and the Internet, etc.), which can realize intelligent traffic management and intelligence.
The integrated network of dynamic information services and intelligent vehicle control is also a typical application of the Internet of Things technology in the field of transportation systems. “

5g and its Significance to Autonomous driving: Why is 5G Better than 4G in Autonomous Driving?
5G is out to accelerate the intelligence of vehicles. Compared with traditional 4G, due to performance issues, the communication speed between vehicles is not fast enough. Besides, such delays do not meet the requirements of traffic safety. After all, in terms of traffic safety, every moment is important because it can be very dangerous.
However, when a vehicle is connected to 5G, because of the low-latency and high-bandwidth characteristics of 5G, the delay can be reduced, which is sufficient to meet the requirements of traffic safety, and basic safety is guaranteed.
At the same time, when vehicles are equipped with sensors, the safety of autonomous driving will be higher, and all vehicles connected to the same network can also relieve the pressure of traffic jams.
How 5G can Help Control/Manage Traffic Jams
Often at times, you may have experienced traffic jams on the highway, but walked over and found nothing happened. This phenomenon is called the Snake Effect. To put this in perspective, let’s assume that the first car on the highway has braked to reduce the speed, and the second car behind it also needs to brake to reduce the speed, otherwise it will rear-end. The third and fourth vehicles must be braked, otherwise, they will rear-end.
This causes the following vehicles to need to apply brake here, which will cause congestion. This phenomenon is actually very common in daily life.
In another scenario, it may be that while waiting for the traffic light, when the green light turns on, the first car moves forward, and then the second car starts. When the red light turns on again, you go under the red light and have to wait for the red light. Such traffic is extremely inefficient. However, if it is assumed that after the green light is turned on, all vehicles are moving forward at the same time while keeping the vehicles relatively stationary so that the traffic efficiency can be greatly improved.
Connecting all Vehicles to the Same 5G Network can Make Autonomous Driving to be More Efficient
Of course, all vehicles can be connected to the same network through 5G technology and a unified dispatch is adopted. Many people say that this method can also be achieved by autonomous driving. This statement is not without reason, if the vehicle is equipped with a lot of sensors, of course, it can be achieved. But when it comes to autonomous driving, some people think that electric cars are patented at this time.
Although it is true that electric vehicles can do better at present, it is not a patent for electric vehicles. The reason is simple: the key to wanting a car to run is the speed and direction of the car.
Obviously, it is not difficult to control the speed of the vehicle and the angle of the steering wheel through the on-board computer. At the same time, a series of sensors are installed around the vehicle body to feedback all the information around the vehicle to the on-board computer, thereby enabling automatic driving.
But now whether it is Tesla, Weilai, etc., the automatic driving implemented by them is calculated locally, and communication between the vehicle cannot be established.
By contrast, if the vehicles are connected together through 5G, The state and information can be shared, the safety of autonomous driving will be higher, the vehicles will be more intelligent, and the road will not appear so crowded.
At the same time, vehicle-road collaboration, vehicle-vehicle collaboration, and vehicle-network connectivity are achieved to build an intelligently networked transportation ecosystem.
Final Thought About 5G and its Significance to Autonomous Driving
With the realization of such technology, traffic safety is guaranteed, at the same time the traffic pressure is relieved.
Of course, this is just one of the applications of 5G technology. With 5G, information can be sent quickly even without a physical medium. In addition, with 5G technology, resource sharing can continue to improve.
With the 4G era, things such as mobile payments, short videos, live broadcasts, online videos, etc., which improve the happiness of life, were born.
In the 5G era, all aspects of our lives will be changed. 5G will be empowered in all walks of life, and then drive all walks of life Industrial progress in all industries.
