 Welcome to the World Radio Communication Conference 2023, WRC 23, here in Dubai in the United Arab Emirates where I've got the great pleasure of enjoying a Mr Satoshi Kobayashi who is a committee member for the Wireless Power Supply System Technology Committee. Welcome to the studio. Thank you very much. Now I would like to ask you Mr Kobayashi, you've been involved in technological committees innovations for quite some time. What is your main topic of interest here? It's called Wireless Power Transmission, WPT. Yes, can you tell us a little bit about what that involves? There are many, many applications or possible applications I would say. But the first thing we were interested in was the wireless charging of electric vehicles. That was really the first thing. But these days we are targeting a much low power devices and it's charging wires, wireless charging of IoT sensors and there are many, many sensors, especially in the factories. They sometimes need batteries but sometimes need wiring to ensure the power but those batteries and the wiring are causing a lot of problems and in one factory thousands of sensors are working in one line, one production line. So it's very cumbersome to keep everything working very well. We're talking about essentially looking at very small pieces of technology being charged all at once, you say. So is that a much more complex and challenging task? Actually Japan has already established regulations for that and products are ready to put into market and sooner or later we will see many, many products in Japan but that manufacturer wants to sell that product all over the world to, yes, that's the situation. And why is the World Radio Communication Conference important? I would say that the wireless transmission is not radio communication and therefore in many countries it's unregulated. It's a new technology but unregulated. It means that they can use any frequency but if they use any frequency it might cause harm for interference to the radio communication services. We should avoid that. Use of radio communication, frequencies for radio communications are decided by the radio communication regulation, which is under the responsibility of WOC and so we want WOC to think about the possibility to minimize harm for interference for that unregulated one. It's very controversial subject. It's unregulated, WPT is not under the responsibility of ITU but the radio communication service may receive harm for interference from them. We should avoid that. Is the answer then to regulate and to reserve certain frequencies for this do you think? If possible, harmonize the frequency globally. The frequency allocation for radio communication services are harmonized globally, mostly harmonized. But as I said that WPT frequency use is unregulated, it's not a good situation. What about the technology behind it in terms of standardization, I'm sure that's an important part of it as well. As far as standardization is concerned, ITUR study groups, study group one has been involved in that work and technology, technical study is done and actually there are three recommendations already approved indicating which frequency bands can be used as a guidance to the radio administrations. And how do you see the future for WPT evolving? It's my personal view. There are a lot of applications for WPT and whereas whatever cable exists, we can remove the cable by using the WPT technology. That means that as you see, we have a lot of cables here and there. Everywhere, absolutely, yes. So a world without cables then, that's the way that you imagine it. It's our ideal situation. And I would say that the application is much wider than radio communication services. Therefore, we may need a kind of a global regulation for that, but currently there is no such regulation. And even the national regulations are not ready. That's a problem. Well, let's hope that they are in the future. Mr Kobayashi, thank you very much for sharing some insights with us here and thanks for being with us in the studio and at the conference. And maybe we'll catch up with you again in some stage in the wireless future. Okay, thank you very much. And our ultimate goal is solar power satellite. So right. Excellent. Brilliant. Excellent. But it will take a lot of time in 20, 30 years. It might be 50 years from now. Sure. Yes. So we won't be around then, but our children and grandchildren will be able to profit from that. Thank you very much indeed. Thank you very much. Thank you.
