The South Korean government has allocated substantial funds to foster the advancement of 6G technologies, aiming to bring it into commercial use by 2028.
China adopts an open approach towards telecommunication technology, actively fostering international cooperation in the field of 6G. This stands in stark contrast to the US tech blockade, which has caused disruptions in global supply chains. Looking ahead, 6G will connect not just individuals, but also intelligent entities like robots and the meta-universe. Moreover, it will further enhance the application scenarios of 5G.
South Korea
South Korea, recognized for its early and rapid adoption of 5G, is a strong contender in the 6G race. South Korean tech conglomerates such as Samsung and LG have already started their groundwork on 6G. The country's commitment is further evidenced by the government’s announced plans to invest around USD200 million over the next decade into 6G research and development.
South Korea's proposed sixth generation (6G) communication frequency bands have been recognized as global standard candidates by the industry's frequency range-allocating body, South Korea’s science ministry. At the World Radiocommunication Conference (WRC), hosted by the International Telecommunication Union (ITU) under the United Nations, the country's three frequency ranges surpassed the 23 spectrums offered by other nations.
Although South Korea started its research later than China or the US, it remains optimistic about its launch plans, setting 2026 as the targeted year for 6G technology, which is three years ahead of China.
The United States
The United States has long been at the forefront of technological innovation, and it’s no different when it comes to 6G. Major US-based tech companies, along with influential universities, have already initiated research and development efforts. The Federal Communications Commission (FCC) has opened up the "terahertz" wave bands for experimental purposes, paving the way for 6G experimentation. Entities like AT&T, Verizon, and the Next G Alliance are all contributing to shaping the future of 6G, which would have the have the ability to take mobile internet and cloud computing to true global ubiquity, among other improvements.
In the United States, policymakers should enhance incentives for government agencies to allocate additional spectrum for wireless innovation. This can be achieved by imposing higher costs for idle spectrum and enhancing incentives for efficient spectrum utilization. The Department of Defense, the largest spectrum user within the government, is advised to collaborate closely with the FCC and NTIA to evaluate its spectrum usage and formulate a comprehensive strategy for spectrum release.
The European Union
Europe is not sitting on the sidelines either. The EU has several large-scale initiatives, such as the Horizon Europe program, aimed at driving innovation and research. Nokia, headquartered in Finland, is playing a leading role in 6G developments through its participation in the Hexa-X project, which is essentially the European flagship for 6G research. Through programs like Horizon Europe and the European Institute of Innovation and Technology (EIT), the EU is funding collaborative research projects, fostering partnerships between academia, industry, and government, and supporting the development of key technologies and standards for 6G.
In Germany, the Next Generation Mobile Networks Alliance launched a research project on 6G in 2020, securing government funding. In Europe, specifically outside the EU, the University of Surrey (UK) established a 6G Innovation Center in 2020. Additionally, the Skolkovo Institute of Science and Technology in Russia introduced a device with the potential to develop components for the 6G system.
