 So here's the Sony XZ Premium. This is going to be the first 835 phone, right? The first announced? Correct. This is the first announced phone to have Snapdragon 835. Of course, it's an incredible phone with a beautiful screen and an amazing design. And one of the other important features about it is that it supports gigabit LTE, so download speeds up to 1 gigabit per second over cellular. And this is a live demo actually that we have of the speed going over the phone. So reach the peak of around 979 megabits per second. So how do you do this demo because there's some cables? Correct. You're getting directly to the antennas? That's exactly. Those are actually the antenna lines because we're not allowed to transmit over the air here in Barcelona. So we actually have it wired up to the LTE tower essentially that we have in the back. So you're not allowed to transmit because only the carriers? Correct. We don't have a license. Correct. We don't have a license to transmit. All right. And this is on the what is the gigabit LTE? Is it a new spectrum or is just the same spectrum better used? It's basically it's actually the best way to think about is the same spectrum better used. So just a few years ago on three LTE carriers with carrier aggregation where you're combining three carriers together we were only able to get peak speed of 450 megabits per second. And now on that exact same amount of spectrum we're getting up to a gigabit per second and the way we're doing that is we're using more advanced techniques like using more antennas. So the Sony Xperia XZ Premium has four LTE antennas instead of just two and that allows it to receive data from four antennas on the tower simultaneously which helps double the throughput. One of the questions that we always get is okay that's the peak speed but what are the real world speeds that I can expect? And so to answer that question we embarked on this pretty massive network simulation. So this is actually Chicago. You went around with this phone there? So what we do is we actually capture the RF environment in the city and then we bring that data back and we put it into a simulator, a very sophisticated simulator that can predict the expected performance for a mix of devices and traffic text. So what we can do is as you see there's different dots of different colors which represents that some people have very basic LTE devices some have more advanced LTE devices so on and so forth until 7% of people have gigabit LTE devices in this network. So what we can do is we can select a cell sector and we can actually compare the performance of the different devices in that sector. So let's say you're doing you know you're downloading a file from the cloud what kind of speed can you expect? So we'll compare median users and we'll compare CAT 6 so that's kind of the common LTE capability of a lot of devices and networks today versus CAT 16 which is gigabit LTE. Okay so what this is saying is that the median CAT 16 user is getting around 93 megabits per second compared to the median CAT 6 user that's getting 50 megabits per second. So again it's not so much about the peak rate but it's about the improvement because there's some thinking out there that some of these advancements that happen in the phones don't actually yield real benefits in the real world but that's not true even though you're not getting the peak speed you're still getting faster average speeds with these devices. Now what happens in the network if I change the mix of devices so the majority of devices are the most more advanced ones watch what's going to happen to the throughputs as I make the change. So the speeds actually went up for both of them and the reason is the gigabit LTE devices use the network much more efficiently and so the network can assign them fewer resources to get the speeds they need which opens up the capacity of the network for other users to get even faster speeds. So really everyone wins with gigabit LTE. How can we get the full throughput? The full throughput well let me show you so this is for the median user if we go to the 90th percentile user you're talking about over 200 megabits per second. What does that mean what you just did? So what I mean is 50th percentile that's kind of the average signal conditions 90th percentile is somebody who's close to the tower. Oh yeah. And so when you're closer to the tower you have a stronger cleaner signal which gives you higher throughput. Can we get even higher? Can we get to 900? So actually like I don't think we can get to 900 but if I were to factor give me a second. Okay you get really good geometry. Okay so that's about. So you're going to burst up to crazy high speeds. Correct. We're talking about fiber in your pocket right? It's exactly right that's that's the message it says right they fiber out the cable download speeds but without the cable. And do the telcos need to install a lot of new base stations for this to work? Not necessarily install new base stations but they if they haven't done so already they need to upgrade their antennas. Fortunately a lot of operators had the four sites to implement four antennas in the towers so now with the devices being capable of having four antennas as well it's actually a software upgrade. Is it hard for the device maker to fit four antennas? Absolutely it's a formidable engineering challenge. It's hard right? It's very very hard and Sony was the first device to do it last year with our last generation Snapdragon 820 and Samsung did that afterwards with the Galaxy S7 as well so there were two smartphones last year they had four by four MIMO but this year you know more OEMs are figuring it out. Sony of course again is the first year to show it with four by four MIMO but there will be other premium tier devices this year they use four by four MIMO to get to gigabit speeds with the Snapdragon 835. The designers of these devices they love these challenges right? They have to put more stuff in there and you provide the technology that can make it work. Make it work all together yeah but it's a formidable engineering challenge but they were able to overcome it which is a great achievement. And if I'm downloading my torrents at this speed is it going to use the battery much faster than an older phone? It's actually the opposite which may sound a little bit counter intuitive so what happens is you're using higher power but you're doing so for a shorter period of time because you're finishing your downloads faster so net net it turns out that typically the faster you go the lower the power consumption is. Are there going to be new companies offering broadband to the home through this gigabit LTE? I believe that it at least opens up the possibility for more people to do so we remain focused of course on the mobile application and the smartphone. If people would do that is it going to interfere with mobiles? No I mean you'd be using exactly the same type of network you know similar modems for example from Qualcomm so it should operate fundamentally the same way. I think what's exciting for example in the United States is the move towards unlimited data plans which is really encouraging people to rethink about how they use their devices and really open up news use cases that people probably would not have considered before with limited data plans. Do you get more bandwidth in a densely populated area or not so densely or medium? So that's interesting it's a shared resource so the more people that you have sharing the resource you know the slower the speeds would be but what the operators typically do is in a dense area with a lot of people they end up installing more cell towers and more sectors in order to make sure that everybody has enough capacity. You can make smaller areas? Correct, correct. So what you do is that you make the cells smaller and you cram them closer together so you know if you're covering a large area you cover a certain number of people if you cover a smaller area by definition you're covering a smaller number of people sharing the same resource. And this one combines licensed and unlicensed? This particular demo does not it's only licensed spectrum but we have another demo over there that does actually combine licensed and unlicensed and still get to gigabit speed. All right let's let's go over there. Okay sounds good. Let's check it out. Okay there's a lot. So you can talk about that too? Yeah sure all right. Actually they can how about they can talk about it because there's nobody else at the at the station there so maybe with Shivani. He's jumping is it right here? Right here over there. So I'll get in here. That was for the 4k 60 frames per second. Correct, correct that's right. So why is it related to that? Unlicensed and licensed mixed up. Yeah so we just wanted to show the benefits of combining licensed and unlicensed spectrum because in order to get to gigabit speed you need about 60 megahertz of spectrum at least and not a lot of operators around the world have you know 60 megahertz of spectrum at their disposal to get to gigabit speed and so what we did was invent this technology called licensed assisted access so that you can send LTE signals over unlicensed spectrum which is freely available for anyone to use. So what we have here is a gigabit LTE network with one licensed connection and three unlicensed connections so 4x carrier aggregation total and we have all of these devices here sharing that same gigabit LTE connection streaming a very high very high quality 4k 60 frame per second videos over the shared pipe so using hundreds and hundreds of megabits per second. So what is this unlicensed spectrum is it it's not Wi-Fi or is it on the Wi-Fi it's on 5 gigahertz or somewhere else? So it's 5 gigahertz it's on 5 gigahertz it's the same spectrum band that Wi-Fi as well as other technologies use and it's freely available for anyone to use. But it's not like a it's not like a short range or is it? It is short range. It's only like Wi-Fi. Correct so the LTE or LAA small cell actually has it's capped at the same power output as a Wi-Fi hotspot there will have slightly better range just because LTE is slightly more efficient than Wi-Fi in some ways but it has the same power output limitation and so this is actually a small cell technology so the operators you know can go into a very highly congested area for example an airport or a mall or a university campus or a convention center exactly right and insert you know put the LAA small cells to boost the capacity of the network in that specific area. So 5 gigahertz is going to be a big deal in the future but this is not Wi-Fi. It's not Wi-Fi it's actually LTE it's actually exactly what is is LTE carrier aggregation and you're just happened to be sending the LTE signal over the 5 gigahertz spectrum. And do you use the 700 old TV space? Do you use that kind of spectrum too? So I mean we support essentially our modem support all of the latest bands that have been made available and approved by the 3GPP the organization that controls the LTE specification. So if there's more bands you just add them in you know how to do it? Correct yes absolutely cool great
