The United States launched 6G research and development. The FCC announced the 6G test frequency band.


Tencent Technology News Today, many countries and telecom operators are competing to build a 5G network, and hope to occupy users in advance. At the same time, countries are also preparing to develop the next generation of mobile communication network technology 6G. According to the latest news from foreign media, the Federal Communications Commission (FCC), a subsidiary of the US government, has begun paving the way for radio frequency in 6G R&D.
According to foreign media reports, on Friday, the Federal Communications Commission unanimously voted to open the “THz wave” frequency segment, and one day, the frequency segment may be used for 6G services. The frequency range is in the range of 95 GHz (Ghz) ​​to 3 terahertz (Thz) and will be open for 6G experiments, allowing engineers who dream of the next generation of wireless technology to start their research and development work.
This frequency segment was once considered to be of no use value. In the future, however, this frequency segment will provide ultra-fast Internet transport services for data-intensive applications such as ultra-high resolution imaging and sensing applications.
According to the relevant rules, the Federal Communications Commission will provide some vendors with a 10-year frequency license to test new products and services.
Federal Communications Commission Chairman Pankit said in a statement: “Today, we have taken a big step towards the effective use of this frequency band. This will give innovators a strong incentive to use these waves to develop new Technology while protecting existing uses.”
The background of this vote is that US mobile communication operators are starting to launch 5G services. At the end of last year, telecommunications giant AT&T opened 5G networks in more than a dozen cities in the United States. This year, it plans to expand its coverage to 21 cities. So far, AT&T has only launched a communication device that can use its 5G network, namely mobile hotspots.
AT&T’s rival Verizon will be the first US carrier to sell the Samsung Galaxy S10 5G. The company will launch mobile 5G commercial services in Chicago and Minneapolis next month.
At the same time, the third-ranked US mobile operator T-Mobile said it will launch 5G services in 30 cities, while the fourth-ranked Sprint will launch services in nine cities in 2019.
In other words, all four US national mobile operators will implement commercial 5G networks within this year, but there will be differences in coverage.
New York University professors such as Ted Rappaport and other mobile communications researchers have led research on 5G millimeter wave technology. He said that opening the above frequency band will help the United States maintain its leading position in the field of mobile communications.
Rapaport said in a statement: “Now, with the relevant frequency plan and this historic vote, the Federal Communications Commission has launched a 6G competition to help ensure that the United States will play in future generations of wireless communications. Leading role.”
Last month, many people in the tech world ridiculed the 6G that President Donald Trump mentioned on Twitter. Trump said in the post that he hopes to see “5G or even 6G network technology” deployed in the United States as soon as possible.
However, the above-mentioned New York University professor Lapapo said that it is not too early to consider the next generation of mobile communication technology.
He said: “President Trump has arrived at 6G in a few weeks, which is probably the first leader in the world to do so. As an engineer and teacher, I am very happy to know that our country’s leaders are working hard to support the United States in science. Competitiveness in technology, engineering and mathematics.”
According to reports, R&D companies also face some technical challenges in using the 6G test frequency segment mentioned above. Like the millimeter wave used for 5G, this terahertz frequency band has some propagation characteristics, and the propagation distance is relatively short and needs to be transmitted within the line of sight. This means that radio signals will not penetrate obstacles, such as walls, and will be disturbed by things like trees or weather changes.
So far, the practical application of this ultra-high frequency band can be confirmed, even without real imagination. But researchers are already thinking about the future. Later this month, scientists and engineers will gather in Oulu City, Finland to participate in a summit of 6G communication technology.
However, Federal Communications Commission member Jessica Rosenworcel said, “It is undeniable that using these stratospheric frequencies (meaning high frequencies) to turn their signal propagation challenges into opportunities is A very cool thing.”
At the end of January this year, South Korea’s LG Electronics also announced that it will launch research on 6G communication technology in order to be able to take the initiative in the future competition. According to South Korean media reports, LG Electronics opened a 6G research center in the Korea Advanced Technology Research Institute in Daejeon, South Korea. The leader is Cho Dong-ho, a professor of electrical engineering at the institute.
In the 4G era, mobile Internet access speeds are tens of megabits or hundreds of megabits (Mbps). In the 5G era, mobile Internet access will achieve the speed of traditional optical networks, for several gigabits, a movie can be in seconds. Download completed. In the 6G era, it is still unclear what level of mobile Internet access will be raised. (Tencent Technology Review / Cheng Hao)
