Oh Gary simply from anger authority we're at the core corn booth here at Mobile World Congress have come to speak to Sherif Hannah about 4G LTE the latest improvements and 5g Shareef nice to see you nice to see you thank you for coming by now I know that Qualcomm have got some 4G LTE announcements you want to tell me a bit about that sure yeah we're very excited because two of our customers Sony as well CC announced the first phones that have gigabit LTE capabilities so up to 1 gigabit per second over 4G LTE which is absolutely astonishing we announced the modem last year but now we integrated into snapdragon a 35 and now it's in phone so it's very exciting that it's coming to the smartphone form factor those are old enough remember telephone modems you know 33k and now we're talking one gigabit I mean that's just amazing yeah I know absolutely and yet to see it working in a smartphone you know getting up to 1 gigabit per second suite is absolutely astonishing but I think the important thing to remember is it's not so much about the peak speed and that's one of the things that we need to get across very carefully that yes we can show we know up to 1 gigabit per second Idealab conditions but actually the most substantial improvement is in the average data rates that people experience on a day to day basis in the network once the networks are actually deployed well absolutely I mean peak is one thing but you know my movie starts downloading really quick at the beginning and then and then dives that doesn't help me so these new things have got sustained performance correct so there's actually kind of a byproduct of the technologies that we're using to get two gigabit LTE for example they use the 4 by 4 MIMO technology which means that we actually put four antennas inside the phone and the phone can receive on the four antennas simultaneously so one of the side effects of that for example is now the phone essentially has additional ears that it can listen to the tower with when you're far away from the tower okay it will actually give you faster speed even when you're far away in addition to giving you insanely fast speeds on your clothes so again it's not just like I said it's not just with the peak rates but actually the average user experience gets a lot better with a gigabit LTE phone than it would otherwise now earlier on I said to you that 5g hasn't been turned into a stand and I think people talking about it too early and you said no that's not true so tell me about loud so the actual final specification for 5g which is by the way called 5 g NR 5 g new radio that's going to be the global standard for 5g so the specification is not finalized yet however that the work in the organization that makes the standard proceeds in phases and in the current phase that where a lot of decisions have already been made about what the new radio interface looks like for example the way it can scale to accommodate insanely high bandwidth but also have capacity for hundreds of thousands of IOT devices or give the ability for autonomous cars to communicate to each other with very low latency to avoid an impending crash so a lot of those decisions for the error interface have already been done ok and we're demonstrating it in the booth today which actually makes that demo quite a bit different than a lot of the other 5g demos that are at the show so 5g isn't just about speed 4g LTE could grow quite significantly but 5g you've got as you said iot devices local devices cars other things talking to each other at low latency and that's going to be the real game-changer I think the 5g what do you think I agree 100% and by the way even from mobile broadband perspective so even with the faster speeds come also much lower latency so on LC networks today you're looking at a network latency of between 20 to 30 milliseconds let's say in the demo over there we're showing one millisecond latency with very very high speed hundreds of megabits a second and so even that would be a game-changer for example for something like motivated rendering of 360-degree video where if you have a VR headset on and you're looking at a portion of video the network can sends you just a portion you're looking at a super high resolution and as you turn your head it can then the network can respond quickly and Center then you feel the view that you're looking at and give you a high resolution there that is not possible with 4G today but it will be possible with with 5g so this is the new exterior xD premium which is the first smartphone with snapdragon a 35 and one of the unique things about it is that it integrates gigabit LTE so up to 1 gigabit per second download speed over an LTE connection which is absolutely astonishing so not only do we have the unit on this way we actually have a real speed test you know these are the seeds that are actually from the device right now up to 979 megabits per second but of course this is a peak rate you know it's the only device that's connected to the tower that we have in the background the question that we always get is what are the real-world speeds that I can expect from these network improvements and device improvements and so we have this simulation that we ran basically simulating about 8,000 users in a Gigabit LC network and the users have devices of different LC capability from category four which is kind of the lowest most basic LC capability all the way up to cat 16 which is gigabit LTE and so what I can do is I can go into comparison modes and see how the real expected real world speeds the devices of different capabilities will get so I'll select one of the cell sectors let's say for FTP traffic types so imagine you're downloading a file from cloud storage for example let's look at the 50th percentile user the average user or median user and then let's compare cat 6 which is kind of the current you know most common you eat LTE capability in phones and networks vs cat 16 the new stuff okay so here we see that the average speed for the cat 16 user is 93 megabits per second compared to 50 megabits per second for a cat 6 users so again not gigabit speed but this is again simulating a real network with real conditions and this is on average and what the other graphs are showing here is also the fact that the cat 16 device is used to network more efficiently so we can cram more users in the network and there's another way to show this which is if I change the mix of devices in the network so that more of them more of the users in the network have gigabit LTE devices watch what happens to the throughput as I change the mix of the devices in the network so okay so the speeds actually went up for both users for the Catholics user as well as the cat 16 user and the reason for this is when you have a higher percentage of gigabit LTE devices they use the network much more efficiently which opens up the capacity of the network so that even users who don't have capable devices to get faster speeds as well this is before the median user but I also want to illustrate kind of the best-case users what kind of speeds they can get so let me go here and select the 90th percentile users I look at that over 200 megabits per second you know in in a real network this is the kind of performance that we expect once the network start rolling out in the u.s. in Europe in Asia and starting in 2017 very exciting tell me a bit about roadmaps I know nothing set in concrete but we took now in 2017 what's the kind of plan that people have got for the standard for hardware for network what was the plan so actually that's a great question it comes at the perfect timing because just yesterday Qualcomm along with 21 other leaders in the mobile industry committed publicly to accelerating the 5g and our global standard and pulling in the date so we can see the first 5g mobile devices and networks in 2019 instead of 2020 so we pulled in the schedule by quite a bit pulling it in to 2019 and also folsome we announced our first 5g new radio modem so supporting the global standard for 5g it says 2g 3G 4G and 5g all in a single chip Wow and so that you can expect the part of the x50 family of modems from Qualcomm so you can expect mobile devices with those new modems in time for 2019 so the first 5g smartphones will be available in 2019 very very exciting well these are exciting times in terms of 5g in terms of mobile communication I wish you all the best it's Gary Sims from Andhra authorities speaking to Sharif
