What role will 5G networks play in the driverless era of cars?

　　Self-driving cars are developing rapidly and gradually entering people's lives. A study released by the World Economic Forum shows that by 2026, 10% of cars in the United States will be self-driving . This is also to a certain extent to allow the technology to mature and popularize quickly. Let's follow the automotive electronics editor to learn about the relevant content.

　　As these technologies develop and grow, the data generated and required by driverless cars is also increasing. Entering the 5G era, the future of self-driving cars looks very bright.

　　Here are some of the positive roles we believe 5G can play in the development of autonomous driving technology.

　　Vehicle Sensors

　　Onboard sensors are arguably the most critical technology. Self-driving cars need to understand their environment and surroundings, and this is where sensors play a vital role. Onboard processing systems allow vehicles to take data input from sensors and process it to guide the vehicle's operation on the road. Based on this data, devices such as radar, lidar, sonar, and cameras make automated vehicles possible.

　　We expect that the performance of 5G networks will create more possibilities for product features and functions. The 5G standard is designed to provide enhanced networking capabilities, including low latency, high-speed mobility, high data transmission speeds and high capacity. These factors will enable critical data from sensors to be effectively connected to the cloud, thereby surpassing the on-board processing capabilities of a single vehicle.

　　V2V and V2I communications

　　In the coming years, vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications will also come to both manual and autonomous vehicles. This will allow them to “see” and receive data directly from other vehicles and road infrastructure, rather than just being limited to what their onboard sensors can sense. Whether it’s from a street corner, from another vehicle, or at greater distances.

　　Complementing the onboard sensors, these additional data streams combined with sensor input will paint a clearer picture of the road and traffic environment around the autonomous vehicle. This gives them greater confidence in the driverless car. 5G technology, with its ultra-high reliability and low latency, will enable people to get the information they need in real time to make real-time decisions with real-time information that plays a more important role than the sensors on the vehicle itself.

　　In addition to these autonomous driving technology improvements, 5G networks will be able to provide users with more information at a faster and more efficient rate, such as detailed map data, software and firmware updates, and enhanced cybersecurity.

　　Predictive learning technology

　　One of the most exciting things about self-driving cars is that they are able to learn from the driving experiences of other vehicles, something that human drivers cannot do. The algorithms that control the operation of self-driving cars will continue to improve as the autonomous vehicles encounter new driving situations.

　　However, to achieve these improvements, data must be collected from self-driving cars, analyzed and synthesized into improved algorithms, and then distributed to other vehicles.

　　Self-driving vehicles must be connected to the internet to do this. Future 5G will ensure this data is exchanged faster and more efficiently, allowing these automated vehicles to distribute and receive data and ultimately function better.

　　5G Standards

　　Telecom and technology companies are collaborating on 5G standards. In fact, lab trials have already reached 14Gbps, exceeding the pre-set wireless 5G connection speed standard. Standards-based 5G technology could be available as early as the end of 2018, with improved 5G capabilities expected to come online soon, and self-driving cars will begin to hit the road. Once deployed, 5G networks and new network technologies that follow them will dominate for a long time, and are likely to support the future of self-driving cars.

　　As we advance our 5G network, we are also addressing current challenges facing connected cars, such as road safety and traffic congestion. Other advances include testing facilities and connected proving grounds to further accelerate the development of autonomous vehicles. Proving grounds provide a range of driving environments and infrastructure for testing and evaluating autonomous vehicle innovations.

　　"As the technology and telecommunications industries explore the future of autonomous vehicles, 5G mobile connectivity will be critical to supporting connected and autonomous vehicles. As we move forward, we will strive to continue to provide highly safe and efficient solutions that will ultimately make autonomous vehicles a reality."
