5G will open a new era of smart networking

The Internet of Things is the "Internet of Things," and the "thing" in the Internet of Things contains many everyday objects. Of course, cars are no exception. Today, most new cars are "networked", implementing in-vehicle communications or Internet access in different ways. However, the industry believes that the launch of 5G may open a new era of smart networked cars.

A reliable 5G network may greatly enhance the capabilities of intelligent networked vehicles and ultimately make self-driving cars a reality.

5G can expand the capabilities of intelligent networked cars

An intelligent networked car is a vehicle that is connected to an external network in some way. This means that the car's functions can be controlled by smart devices. The car itself can act as a mobile 4G hotspot, and drivers can receive information on the move, such as navigation or traffic. data.

In fact, smart network car is not new. In 1996, GM and Motorola collaborated to introduce the functions of car networking to various Cadillac models. In 1996, the first cars with networking were on the road.

At present, about 21 million intelligent networked vehicles are driving on the road. Their functions range from monitoring failures to contacting emergency services. They can even use applications to remotely open and close doors and remotely start air conditioners.

According to Counterpoint’s research on the Internet of Things tracking service, it is expected that the global market for connected cars will grow substantially in the near future and will increase by 270% by 2022. It is expected that more than 125 million embedded networking passenger vehicles will be available in 2018-2022.

In short, 5G is the latest generation of mobile networks. With high bandwidth and low latency (lag), 5G is far faster than previous generations. It is expected to be launched in the UK in 2020, and the industry believes that one of its main applications will be in the automotive industry. According to Emmanuel Lugagne-Delpon, senior vice president of the Orange Lab Network, Smart Connected Automotive is a key application of 5G, and Smart Connected Automotive is one of the most difficult and demanding application cases in 5G.

5G can achieve V2V (vehicle-to-vehicle) and (V2I) vehicle-to-infrastructure communications with speed and capacity that are unmatched by previous-generation networks. Compared to 4G, 5G uses a different wireless spectrum frequency, which means that it can connect more devices to the Internet without interference from 4G.

The low 5G delay means that there is no noticeable delay between sending and receiving signals. This is critical to safety, especially in self-driving vehicles.

At present, the automotive industry is inspiring the potential of 5G smart networked cars. Just last month, Audi announced that it would cooperate with China’s communications giant Huawei Technologies to launch a model equipped with 5G networking technology in 2020. The introduction of this technology will allow vehicles to achieve safer semi-automated driving through V2X communication technology.

Similarly, earlier this year, Samsung announced the launch of the 5G Smart Connected Vehicles program, saying that it will become "the industry's first automotive solution for 5G."

5G and automatic driving

The future of driverless cars is beyond question. Tesla has already announced that the upcoming V9 software update will include "fully automatic driving capabilities." However, the industry believes that driverless cars can only be fully operational after the widespread implementation of 5G.

Neil Shah, research director of Counterpoint Research, said: “The 5G connection of the car is expected to start from 2020. However, the overall penetration rate may continue to be sluggish by 2022. With the popularization of 5G coverage, the level of automotive automation technology will improve. It will also determine the use of automotive embedded 4G or 5G technology after 2022. In addition, the introduction of the 5G NR (Standalone or SA) model can reduce latency, which is critical to driving the commercialization of self-driving cars in the future."

For safe driving, self-driving vehicles need to communicate with each other to reduce traffic jams and collisions, and use radar and cameras to re-analyze the driver's situational awareness of the environment, 4G speed is not enough to work at the speed required by self-driving vehicles, due to 5G It can be done without relying on wide area network coverage, so 5G is crucial for autonomous driving. In addition, networked autonomous vehicles will need to receive and generate large amounts of data, which requires 5G functionality to download real-time information on traffic, danger, and environmental conditions. In the era of self-driving, people may no longer be drivers but passengers, and the higher bandwidth provided by 5G may turn the entire intelligent networked car into an entertainment system.

Although it may take some time before driverless cars become normal, some companies have made progress in combining these two cutting-edge technologies. This month, Baidu and China Mobile announced that they will cooperate to develop a self-driving car platform using 5G. Dr. Christoph Grote, senior vice president of the electronics division of the BMW Group, stated that “We expect 5G to become the world’s leading mobile communications standard for the next decade. For the automotive industry, 5G must meet the challenges of digitalization and autonomous driving.”
