Chinese academic researchers and telecom operators are leaving no stone unturned in efforts to establish a beachhead for 6G, the next-generation wireless technology that has already turned into a key battleground for innovation and industrial transformation.

Despite growing geopolitical interference in the global telecom industry, China has a solid foundation in telecom talent and patents, and its edge in 5G will help the country gain an upper hand in the race toward 6G research and development, experts and company executives said.

The comments came as the world enters a crucial window of opportunity to identify technologies and formulate key standards for 6G. While there is still no universally accepted definition of the technology, 6G is expected to have far lower latency, higher speeds and more bandwidth than 5G.

More importantly, the technology will be able to support the integration of space, air, territorial and maritime communication technologies, which will spawn a wide range of innovative applications, they added.

China is aiming to commercialize the technology around 2030. "We will kick off a string of scientific projects targeting 6G and aim to achieve breakthroughs in crucial technologies," said Jin Zhuanglong, minister of industry and information technology.

Progress underway

In July, a group of Chinese telecom engineers announced they had established the world's first field test network that integrates communications and intelligence.

The experimental network has achieved remarkable improvements in key communication metrics, including capacity, coverage and efficiency, according to Zhang Ping, a Chinese Academy of Engineering academician and a professor at the Beijing University of Posts and Telecommunications.

The network serves as a platform for research institutions conducting theoretical research and initial verification of 6G pivotal technologies, and effectively lowers the entry threshold for 6G research, making it more accessible for innovation, according to the team of engineers.

"The European Union, the United States, Japan, South Korea and other countries and regions have all initiated research on 6G, and China has unique strengths," said Wen Ku, director-general of the China Communications Standards Association.

China has made remarkable strides in 5G infrastructure, which gives it an unparalleled edge in exploring 6G technologies, he said.

By the end of May, China had built over 3.8 million 5G base stations, accounting for 60 percent of the global total. These advances have helped position China as a global leader in 5G technology, with over 60 percent of mobile communication users in the country now utilizing 5G services, according to the Ministry of Industry and Information Technology.

Meanwhile, China has handled over 94,000 5G applications in industries such as manufacturing, mining, power, ports and healthcare, the ministry added.

"Advancing the use of 5G is like building a good bridge and road for 6G, and efforts to promote the large-scale application of 5G will lay a solid foundation for 6G development, which is still in the early stage," Wen said.

More importantly, the country already has an early edge in 6G patent applications over the US and Japan.

China's 6G patent applications accounted for 40.3 percent of the global total, and topped the list of global 6G patent filings, according to a survey conducted by Japanese media company Nikkei and Tokyo-based research company Cyber Creative Institute in 2021.

The US and Japan took second and third spots on the list with 35.2 and 9.9 percent respectively, followed by Europe with 8.9 percent, and South Korea with 4.2 percent, the report said.

In the telecom industry, countries with core advantages in previous-generation wireless technology are more likely to gain advantages in next-generation technology and achieve technological leadership and promote healthy industry development, China Galaxy Securities said in a research note.

Yang Guang, senior chief analyst at the global market research company Omdia, said: "China believes that a mobile network is an important infrastructure that needs to be built ahead of schedule. Once the road is ready, cars will come naturally. The underlying condition is that Chinese operators are all State-owned enterprises and need to bear considerable social responsibility."
