The Future of 5G with Paul Scanlan CTO Huawei Carrier Business Group

Automatic TRANSCRIPT

Welcome Paul thanks very much under now. I've just been very fortunate to sit around a round table with a bunch of influences. And you're quite candid about you know the challenges that you face in the industry but this podcast is about the future of and I wanted to talk about the future of Five G. Sofa my listeners out there that may be in markets where five gs and live or just been launch. How WOULD YOU DESCRIBE FIVE G? And why's it better than four g you know Andrew it's This is probably the most misunderstood technology. It's been bandied around as being everything from the you know the evil of the world to To the savior of the world right and I think the answer probably leaning towards the latter. Which is you know. It's something that really will transfer so I like to think of I five as a platform for transformation. Went talk about it as a speed thing or this thing or that thing. I'll just terrific platform for transformation. Everybody says you know five G. It's faster it's this that and everything else when we talk about them. Do you operate four G. And how do you operate five G? When we operate forgery generally we designed it for this thing called twenty megahertz of spectrum because in three G it was five Megahertz Chunks of spectrum. And therefore more megahertz means you get more spectrum. Generally you get more bang for your buck when we talk about five Jay. We're talking with starting with one. Hundred doesn't mean account. Wigan Eighty or seventy six fifty or ten yep but it was originally thought of. Let's try it for for for one hundred MiG. One hundred twenty two one mistake now. Of course you've got the up link in the downlink say have maybe it's about two or three to one put it in called a spider spider. So you have about two times or three times more spectrum so you're really not comparing for and five Jay in like for like we learnt Andrew many years ago five years ago in doing you think Oh. Wtt X. Wireless to the something. We learnt that we could provide wireless communication as a sort of an alternative center. A Better Time. To market than fiber by deploying wireless buys technologies to provide home-based broadband solutions. Because you build an anti put an antenna and you can sell it so cash and carry you. Get Five Mega. Hit megabits per second team. Maybe one hundred right now. This fixed product is competing with the mobile product. The second one is the bane with these not there so you don't really have enough resources but we learned very quickly that if we were able to put more antennas in we call the massive. Mimo. Then you end up with a better better result. Suddenly you can offer not three hundred customers. Ten makes you could offer three thousand customers teen makes and the more customers more Abu more money simple. It's all about money so now comes five G. so five G. The first thing we do so we've already got some empirical evidence about how much more efficient having one hundred megahertz of spectrum is in this. Wimax area. We're using two point. Three two point five. We've picked a different spectrum. Three point five GIG which means three point two to three point. Six three point eight. Maybe four point two to four point six just relishes the higher the frequency the more efficient it can be she can get more bandwidth through the high frequencies. Would you get you get larger amount of contiguous ECKSTROM? Yes and understand a little bit about how breaking spectrum up into blocks become very inefficient but if you have a big block of spectrum absolutely right and that's why the millimeter wave even higher stuff is even far more beneficial because you have a clear one gigahertz and suddenly war instead of five megs of got one GIG. Simple physics tells you you're GonNa get more bang for your buck. Yeah so five. G. Comes along with starting the premises. One Hundred Megahertz Huge leap ahead of four G and we've got these improvements inefficiencies. So that's what Linda lend lend itself to the high throughput but wait. There's more right and the more big comes to about things like lighten city and massive connections. So we could already see that the challenge is always the always the latency at the air interface and the reason for that is because you could imagine from a base station probably in developed countries. You can have five back to the cornet work for the back to the corner. Work five milliseconds into into the top rate Japan. Top to bottom ten roughly these sort of rough guidances of how how much delay you have across these areas. But if you want to do things that are more interesting like connected car. You don't need five Jay for car but You know if you want autonomous driving. It's one of the options. Yes you could use other methods. But that's not the the most important but if you take a robot right if you've ever shook the hand of a of a rebel with articulated digits but the first thing is if you want one hundred kilos of metalwork comes toward you put something out the first step back of course when you put your hand out and you grab it if the latency is not really shop. Then by the time it gets feedback in squeezing your hand it's probably to light my crusher hand. You got it so we need latency so there's a practical example. Yes but you have more certainly connected car within a couple of meters. The shorter duration robotics interaction. Let's talk about the medical profession if you wanted to do telemedicine remote medicine. Yes so between a practitioner. Highly capable person. Let's take a simple like it's not really simple. Let's take ultra ultrasounds. So you have an expert a technician. The journey woman sitting there with a couple of hundred grants with equipment. What about the village? That's you know two hundred dollars or three hundred kilometers wide. So we just discussed about this thing called latency. What about if I wanted this person to do some remote monitoring of a man or a woman or somebody on the on the I and we've got these tactile feedback devices now? Yes but the person is a couple of hundred Roy. So you imagine. There's a basic person. Triage a stripping. His thing to your body for a couple of thousand dollars which is cost effective. And you got the expert with brain paranoid analytics copy with scopes and everything and now. He presses and two hundred kilometers lighter. It's pressing on you. And then by the time he gets the feedback. He's got to realize that I shouldn't push too far because it's the robot prom you don't want to crush the got it so this this problem. So this is lighten savings on. He's a couple of industries and a couple of sectors that where you can feel that latency. We important robots inside the factory today factory in factories. Andrew haven't changed in one hundred fifty years. Everything is serial from the day we industrialized in the UK. Right I give you the material you do your bit. You Pass it to him. He passes it to her. She personally what happens today? Robotic PLANT ROAD. I does this positive robot. By-pass Robert C. So let's suppose this boardroom. Were nail which vacant and a couple of hours is the Knicks factory from twelve six income the robots willing themselves around connected with five G. They're from different companies. Kawasaki. Ibb ETC. And they're all connected to the cloud by five. G. So the latency is really small. And of course if you take beyond this. This is not thing of few connections to multiple connections per person to devices everywhere. Lamppost ties dresses salt pepper. Shakers everything the cup of tea bags or connected and they will be. You might think it's stupid but you know today it'll get down to something you know a third the size you now. Then everything's connected. If you have that competition of connectivity things in a cell a mobile cell with people you have come back to the first. Problem fixed wireless existing and with mobile paging competing for resources. And it's signaling resources. Yeah and you won't have a few thousand people per sale. You might have hundreds of thousands but the thing with it is. You don't need the speed because some of these things are transmit low data rate but if you've got millions of them in the same spot they all want to compete for radio spectrum to say. Hey I want you to get your data you got it and so you're quite right after that. The data rates are pretty small and listen to a couple of K. kilobytes. But you have a lot of them and it's a signal you know. I've got to wake up not communicate to the end so it's a bit like ceiling overhead traffic. It's it's competing for this. Some of the data so there's a lot of optimization bottomline so affected that in so that's why you have speed latency and throughput as the three key components of five G. But what nobody ever talks about is the social impact five g. and the social impact directly about energy. So you know. Today we're at the product and solution launch of lawyer and we announced that we have a five G. product. That is now. It went one year ago. Forty kilos to twenty five. From two hundred Megahertz bandwith to four hundred megahertz bandwidth but also consumes about the same amount of energy as four J. site. So you've just gone for something that's twenty to one hundred times better for the same amount of energy so some of the analysis that's been boy very specifically by a company called steel partners a consulting company here in the UK. And they've done some analysis based on you know while always products in an older competitor's products looking at all the networks around the world and their energy consumption and a very simple tagline is if you keep building four g networks you double the carbon footprint the planet but if he's five g. It flattens out and it starts to reduce in five years. That's not a bad reason for deploying five G. above the other I think you're great storytellers. It'll just had the opportunity to spend an hour and a half in the room and you. You mentioned the point about your station equipment. Going down in White told a great story about why wife now people know about while we for all different reasons but I love the story about how the thing dropped in. Share that story so I was at a meeting in headquarters and the CEO is sitting at a table with with a number of US including the product and they director in the product. Our Day director was showing the new version of the first five G. Base station that we're going to be launching in a few months and the white was forty five kilos Andrea and he said left on the table. What do you mean forty five kilos? Don't you understand occupational all health and Safety in Europe? It's forty kilos. Everybody looked at him. What does that mean and he said you need a crane. If you need a crane to install this. Do you know how expensive it'll be for our customers? They want. And how the time delay plus the expense and everything. Everything's the wrong wrong targets. You know the capital equipment costs too high. Three months later are endangered. Came back in forty kilos right. Thank you very much forty kilos. We launched now with twenty five kilos and he just on stage and said. Do you know why it's twenty kilos because a person is allowed to carry a twenty kilo product and install it and you know so we're always thinking about how do we improve person the customer's business. It's not about. We've got a great product you want to buy it or you buy this product because it's got these features we're always thinking about from the customer's perspective and generally everybody has the same. Kpi therefore KPI's it's called Revenue Prophet brand market share. You want all of those things. That's what you want right. That's the key metrics so we always think about those components whenever we building products or solutions or focusing on customers. And things like
