How should "radio waves x Internet" evolve for "6G"?Jun Murai and Ryuji Yukawa talk about their thoughts in the book "Anwirad"

The smartphone becomes faster at 5G ... isn't it just?Based on the Internet, you can see the "5G impact"

――Please tell us how you wrote this book.First of all, Mr. Yukawa is walking around a company with state -of -the -art mobile technology worldwide.

Mr. Yukawa: In Japan, it is 5G ears in 2021, so I think the image of 5G is amazing anyway, but with 3G, 4G, 5G from the mobile phone, "5G is faster for 5G.I have the impression that it has stopped by understanding.Certainly 5G is hard to understand.3G is easy to understand that "you can call anywhere" and 4G can use SNS anywhere using a smartphone, but there is no such thing in 5G.

　5G can provide a variety of functions for various network demands.As a use case, automatic driving and smart city are also said.But I think what was really important was what to do with this when the completely digital wireless network became a basis infrastructure for various industries.I guess it hasn't been told much yet, and if 5G is not technically understandable, it wouldn't be good for the future of Japan.I had that kind of thought.

――Murai is used to be a “Japanese Internet father” and is now in a position to advise the government's digital policies.

Murai: I often ask what impact of 5G and how to change our lives in government meetings and media interviewsI thought how to convey the importance.

　For example, in the current 4G era car navigation system, even if the location information is known, it is not known in the 3D space.That's why I can't distinguish between Metropolitan Expressway Route 3 and National Route 246.However, if you try to sensing that the drone will fly, travel in a wheelchair or a baby carrier, or to walk for the elderly, it will be essential to wirelessly capture the three -dimensional space and that each person is connected.come.

　In terms of technical perspective, it is called a "digital twin" that links the calculation, real space, two -dimensional space and three -dimensional space.However, it is already necessary to change our living space in the digital space, as Pandemic and online activities have become more popular, VR and AR games have gained popularity, and in digital space.I feel that it is widely recognized.So, even if you don't know the word digital twin anymore, if you explain it properly, you will understand that the idea itself has an impact on not only specific people and industries, but also everyone in society.I think.

Mr. Yukawa: The greatness of 5G is easy to understand if you think of the Internet as a foothold.The Internet is a common infrastructure that rides on various things, such as e -commerce, SNS, news distribution, video distribution, VR, telephone.There is no Internet only for one service.5G is also the Internet itself.In 5G, smartphones are only one of the many axes, and all industries come on this 5G.

――It means that you should look at the Internet again, including not only mobile technology but also cultural trends.

Mr. Murai: 5G is certainly an important key, but it can be called a social base only by using everything that connects to the Internet wirelessly.It can be said that the title of this book is not radio waves or wireless, but "unwired".
