 So here's the the world's first multi wireless charger. It's charged with everything. Yes So there's a major three standard in the market today. It's A4WP, PMA, and WPC So which one is which? Like when is the CHI? Which one? CHI is the WPC. CHI is the WPC logo So this one is WPC. But how does WPC work compared to the other ones? Okay, WPC actually the technology based from the Megane induction So the technology is actually quite a mature but there's some limitation for example When you have a device on the top you can charge it at it But if you don't align the foil very precisely you cannot charge it So is there some they would need to have some kind of magnet to align it? No, Megane But so because they Megane will cause some system problems. So it's another really Mainstream right now. So that's CHI. Is that the most popular right now? This is the most popular right now. So all the CHI charger in the market you see will have a similar problem And there's a lot of companies working together in CHI, right? Yes So most of you can see maybe 80 to 90 percent in the market today. They're using CHI But it's still it's the most popular but it's still limited It's not ever like it's only a few percent of people have this, right? Correct So I think that this is also one of the reason why CHI Technology you see a standard is everywhere, but there is another really widely adopted So that's the CHI that's the most popular and what is the A4W? A4WP. This is the A4W So A4W isn't C. Just compare with this 2-2 transmitter. It's been charging area. This is an effective charging area So everything can charge everywhere. Yeah, so if you have your phone here, you can charge Does it charge the same devices or it's because you put it inside? Does the MediaTek 3 want it? Yes Yes, we have it here. We have our chip here already and although we come out with a solution Let me turn to the other one Which companies are making this one? The company making this one is next to you. This is the company they are coping But yeah, this is the brand name will work with somebody so the LDM for them Inside this pad actually is the Intel Intel, so this is the Intel standard. Intel solution for A4WP A4WP and so a few companies are using this one and it's very different from this internally So but your concept with 3.188 is that one MediaTek phone will work on everything Yes, that's our goal. One receiver solution will go with all the standard So you can see it's charging And the last one, PMA. What is that? PMA is another standard. It's only popular in North America Sorry, we don't have the PMA here today So which company is doing the PMA? Is it another brand for that? Like Qi? Is it something else? Yes, it's a standard But I think there's only one company PowerMate working on all the stuff So PowerMate and then there's Intel, what do they call it? Intel? They call it A4WP But they have another name also, Intel wireless charger Yeah, they have a logo called the Resense Resense? This is the logo And so how do you do to have this technology in here? How big is it inside? I can show you, you know, actually you see this iPhone, we have a sleeve here This is the same with the iPhone 6 Plus If you open it up, our module is just looking like this So this is the PCP area and this is actually the coil So you need a coil like this, how big is this coil? This coil is something about 73 by 55 It has to be like this at the back of the phone or it can be at the end or under the battery or where? Yeah, it needs to be, you know, if you see, this is the inside of the phone When you attach your phone, it needs to be outside At the bottom of the phone? At the bottom of the phone Yeah, and the coil face outside Alright, does this kind of wireless charging interfere with antennas or anything? Or is it designed to never interfere? Well, I think the answer is yes So in the integration of design, there's something you need to try to avoid that So that's why also you see there's a fair right requirement here Because this can shield the mechanical field with your phone Yeah, so I think there was certain things you need to do But I think we have shown this is achievable So this PCB right here, it has the 3188 as one of the chips on here Can this be integrated inside the MediaTek, you know, like maybe Future SoC will have it inside? Well, I think that's possible It's about if we should doing that or not Because today like most of the mobile phone makers They are not really endorsed on this technology So you see that's why the accessory maker is more aggressive So I think this should be when, the question of when Not really if we can do that or not Is this an ARM processor or not? Or does it go together with a separate microcontroller? No, it's not Our chip we do have a microcontroller but it's not ARM based The receiver side technology is actually, it's simpler So you don't really need to go to ARM And what you just showed me here, is this the same size as if you are doing a Qi receiver? Is it going to be the same size or more bulky? The coin size will need to be bigger Because like you see this one This is our special technology here You see there's a two turn of a coin Then the outer coin is actually for the mechanical resonance The inner coin is for MI, mechanical induction And it's actually used by the WPC and the PMA So usually PMA and WPC use a small coin But on the resonant you need a bigger coin Because you have a bigger charging area So the coin is always bigger, better You can have a better coupling on the mechanical field And for all these technologies there's a little bit of loss of power Like leakage? Yes So which one is the best? What do you think? Qi, using an MI is the best So if you compare with a USB cable, direct charge The efficiency, system efficiency of a Qi is something about 70-80% But on the resonant you could drop to something like 50-60% So there's a big difference here So this solution is being shown, but how soon is it everywhere? Can people buy these cases already? I think this question goes to Jerry Because we build the device, we build the chip, they build the end product But like what you see, most of the stuff is already ready They are working on something about the mass product So you make those cases? Yes And so how soon are you launching those? Are you launching them already? How soon? How soon are you launching them? How soon are you launching them? August August, maybe a few months later And then it will be for iPhone, iPhone, iPhone and some other stuff Yeah, depends on the market requirement They can make a different kind of accessories
