项立刚6G的饭须一口一口吃据称这块磷化锢化合物半导体芯片在300HHz频段进行了高速无线传输实验,峰值速率达

据称这块磷化锢化合物半导体芯片在300HHz频段进行了高速无线传输实验,峰值速率达到100Gbps。技术的突破是永无止境的,这样的芯片在通信技术发展中又迈出重要一步,令人欣喜。有媒体把这款芯片定义成6G芯片,还有人认为这是日本6G取得了大突破,超越了中国5G。但笔者认为下这个判断还为时过早,对于6G我们应该有清醒、科学的认识。

The phosphide-impregnated semiconductor chip is said to have carried out high-speed wireless transmission experiments in the 300Hz band, with a peak rate of 100Gbps. The technological breakthroughs are endless, and such chips are a welcome step forward in the development of communications technology. Some media have defined the chip as a 6G chip, and others believe it is a big breakthrough for Japan's 6G, surpassing China's 5G. However, the author thinks that this judgment is too early, we should have a sober, scientific understanding of 6G.

什么是6G?应该说今天还不知道。各国对于5G之后的6G应该是什么样子,仍只是提出自己的想法,这些想法需要在全世界通信业进行交流和完善。所以,各国研究机构现在都只是发出关于6G白皮书,提出自己的理解。在这一基础上,国际电信联盟会召开相关会议提出关于6G的愿景。这个愿景和5G的三大场景一样,6G也应该有场景及针对这些场景实现的指标。

What is 6G? It should be said that today is not known. Countries still come up with their own ideas about what the 6G after 5G should look like, and these ideas need to be exchanged and refined in the communications industry around the world. As a result, national research institutions are now merely issuing white papers on the 6G, offering their own understanding. On this basis, the International Telecommunication Union will convene relevant meetings to present a vision for 6G. This vision, like the three 5G scenarios, should have scenarios and targets for those scenarios.

在愿景的基础上,国际标准化组织会推动6G标准的建立,各个国家的相关企业将提出标准立项,围绕这些立项再制定相关标准。在标准完善的过程中,各国的通信企业会围绕这些标准开发产品,进行室内实验,再进行外场实验。最后架设网络,向社会提供服务。

On the basis of its vision, the International Organization for Standardization (ISO) will promote the establishment of the 6G standards, and the relevant enterprises of each country will propose the standards for the establishment of the relevant standards around these projects. In the process of perfecting the standards, communication enterprises in various countries will develop products around these standards, carry out indoor experiments, and then carry out field experiments. Finally, a network was set up to provide services to the community.

目前全球的6G发展仍处在逐渐形成愿景阶段。在这个意义上,没有一项技术是国际上认可的6G技术,也没有一项技术肯定会成为6G的技术。日本公司研发的这块芯片,严格意义上说是太赫兹频段的通信芯片,虽然对于6G在愿景讨论时有很多专家提到了太赫兹频段,它提供大量的频谱为高速通信提供了可能,但6G是否肯定用到太赫兹还难以预计。就如5G标准讨论时,全球都认为为了支持更高的带宽必须采用毫米波,各国也对5G做了毫米波的频率规划,世界多个企业着手进行了毫米波技术的开发。但因为存在较大的技术难度,目前全世界的5G主要是Sub6,也就是6GHz以下的波段。要广泛采用毫米波还需解决更多的技术问题。

At present, the global development of 6G is still in the stage of gradual formation of vision. In this sense, no technology is an internationally recognized 6G technology, and no technology is sure to become a 6G technology. The chip, developed by japanese companies, is strictly a telecommunications chip in the terahertz band. Although many experts have mentioned the terahertz band at the time of the discussion of the vision, it provides a large spectrum that provides the possibility for high-speed communications, it is hard to predict whether the terahertz band will be used. As in the discussion of the 5G standard, the world agreed that millimeter-waves were necessary to support higher bandwidth, and that countries had made millimeter-wave frequency planning for 5G. But because of the greater technical difficulty, the world's current 5G band is mainly Sub6, or below 6 GHz. More technical problems need to be addressed if millimeter waves are to be widely adopted.

6G仅是5G下一代技术,除了通信芯片之外,能否设计出可安装在终端和基站中支持太赫兹频段的天线,这都是一些复杂的问题。因此,笔者认为日本这款支持太赫兹频段的通信芯片很有价值,但将它变成真正意义上的6G技术,距离还很遥远。

6G is only the next generation of 5G technology, in addition to communication chips, the design of antennas that can be installed in terminals and base stations to support the terahertz band, which is a complex question. Therefore, the author thinks japan's telecommunications chip, which supports the terahertz band, is valuable, but it is still a long way from turning it into a real 6g technology.

如今,中国的5G技术在芯片、通信系统、终端、应用等各种层面都走在了世界前列,同时6G的脚步也并没有放慢。目前,从科技部到工信部再到研究机构,早已有多个部门在做相关工作。华为、中兴、信科等众多中国通信企业也在做相关技术积累,还有很多前瞻性的技术(包括太赫兹技术)都是电子科技大学等高校的研究课题,水平在全球也处于前列。不过既然现在全世界对于6G连愿景是什么都没定义,不急于把某项技术宣称为“6G技术”才是科学的态度。

Nowadays, China's 5G technology is in the forefront of the world in chip, communication system, terminal, application and so on, and the pace of 6G has not slowed down. At present, from the Ministry of Science and Technology to the Ministry of Industry and Information Technology to research institutions, there have been a number of departments to do related work. Many chinese telecommunication companies, such as Huawei, zte and xinke, are also doing the technology accumulation, and many forward-looking technologies (including terahertz technology) are research topics in universities such as the university of electronic science and technology, and the level is also in the forefront of the world. But since the world now has no definition of what a 6G vision is, it's not rushing to call a technology a \"6G technology \"that's scientific.

通信技术是全人类共同推进的技术,无论哪个国家取得突破都令人欣喜。有了4G、5G的积累,相信中国在6G领域依然会走在全球的前列。(作者是信息消费联盟理事长)

Communication technology is a common advance for all mankind, and it is a welcome breakthrough for any country. With the accumulation of 4G and 5G, it is believed that China will still be in the forefront of the world in the field of 6G. (The writer is Director of Information Consumption Alliance)
