Autonomous driving technology, has a history of several decades in the 20th century, and shows a practical trend in the beginning of the 21st century. At the same time, after a long period of development, 5G network and technology have become another powerful boost for the upgrade of autonomous driving technology in the 5G era. So what exactly does 5G have to do with autonomous driving?

Vehicles need to be fitted with a range of sensors to enable autonomous driving technology. These sensors continuously receive and respond to surrounding information, which is then integrated to make safety decisions. However, in practical application, the application of sensors is often affected by various external environmental factors, which leads to a great reduction in transmission effect. C-V2X (information exchange between the car and the outside world) could make up for the sensor's lack of perception. Among them, the Internet of Vehicles (IoV) technology based on the cellular network interconnects the information between the automobile and the network, vehicles, road infrastructure, pedestrians, etc. With its high speed, high reliability, low latency, network structure and edge computing ability, 5G network built by 5G mobile routers can enhance the capability of autonomous driving perception, decision-making and execution at three levels, so as to make the operation of autonomous driving technology more flexible and the network connection more smooth.
