Recently, Jiangsu Zijinshan Laboratory announced significant progress in 6G technology, which has achieved the world's fastest data transmission speed in the terahertz band, which is an important part of 6G technology and represents China's significant progress in 6G technology. Will consolidate China's lead in 6G technology.

The industry knows that 6G technology will use terahertz band, because terahertz band is rich in spectrum resources, which can provide greater capacity and data transmission rate, so all parties around the world are actively developing terahertz technology. China has been able to achieve the fastest data transmission rate in the world because of its previous accumulation based on 5G technology.

As the global leader in 5G technology, China has built the largest 5G network in the world. So far, the number of 5G base stations has been nearly 2.4 million, accounting for nearly 60% of the global number of 5G base stations. As a result, it has accumulated rich technology and experience, and adopted the 100m spectrum of intermediate frequency band in 5G technology, which has sufficient advantages in 3D antenna technology and MIMO technology.

On the basis of 5G mid-band technology, Chinese science and technology enterprises have developed 5.5G technology, using 100GHz band and 800m spectrum width, which will further enhance China's technological advantages in multi-antenna technology and MIMO technology, which will be used in 6G technology, because 6G technology uses higher terahertz band and wider spectrum. These technologies accumulated in 5G technology are just helpful to the application of terahertz band in 6G technology.

It is based on these accumulation that Chinese scientific research institutions are able to test data transmission in the terahertz band and achieve the fastest data transmission rate in the world, thus consolidating China's leading edge in 6G technology and ensuring that China has more initiative in the development of 6G technology in the future.

It is based on these accumulation that Chinese scientific research institutions are able to test data transmission in the terahertz band and achieve the fastest data transmission rate in the world, thus consolidating China's leading edge in 6G technology and ensuring that China has more initiative in the development of 6G technology in the future.

6G technology will not only be limited to ground communication, but will also include satellite communication technology, thus forming a network of interconnection between heaven and earth. While the United States relies on satellite communication technologies such as star chains, facing the advantages of the United States in satellite communication technology, China has planned the earth orbit satellite communication technology such as the Hongyan constellation, and the commercial Beidou satellite system has some high orbit satellite communication capabilities, in terms of satellite communication technology. In fact, China is not much behind the United States.

In fact, the terahertz technology that China takes the lead in testing is also conducive to the development of satellite communication technology in China, because satellite communications need to use the terahertz band, and because the terahertz band is rich in spectrum resources, both satellite communications and terrestrial communications plan to use terahertz band, and China's lead in terahertz technology will consolidate China's technological advantages in satellite communications and terrestrial communications.

China's advantage in high-frequency technology precisely proves that China does have sufficient advantages in 5G technology, and now these technological advantages will continue to extend to 6G, which will be a big blow to the United States. The hope that the United States intends to use satellite communications technologies such as star chains to gain advantages in 6G technology will be dashed.

The competition between China and the United States in mobile communication technology is so fierce that the advantages and disadvantages of mobile communication technology are not only limited to the mobile communication field, but also affect many emerging technologies in the future, such as the Internet of things, autopilot, AI and so on. China's leading advantages in 5G and 6G technology are strongly pulling China's development in emerging science and technology fields, and are expected to take a leading position in these emerging science and technology fields, which the United States does not want to see.
