 Thank you very much ladies and gentlemen. It's our pleasure to be here and present our company Roder and Schwartz but also the solution That we developed within the framework of the standardization of the t-sector in ITU So that is why we have a very close relation to this WTSA and whatever is happening here in this event. Let me quickly start with a Small overview We are still a privately owned company, but we act globally We were founded 85 years ago by two guys. No surprise from Roder and Schwartz So still the name that we have in the company We are fully owned by the families still we are independent in the financial and capital market and we have a tradition that we Work and act on long-term sustainability and a trusted based customer relationship Since it's it's founding we have or understood ourselves as an enabler and innovator For a safer and a connected world So this is an overview of the business fields that we basically have So our large portion is test the measurement Then we have technology systems that is all where you need a couple of equipment bound together in a complete solution and our latest part is network security Not only our products we are proud of we are also proud of our experts our employees So from a size we have worldwide 12,300 employees we have employees from 87 countries of the world and we are active with a direct representative representation in 70 countries. We do a lot to train our stuff with more than 400 training courses internally to keep keep everybody up-to-date and Of course, this is an asset. We have our engineers are very important to have successful products and I'm happy to Introduce Jens Bagger dr. Jens Bagger who is the head of our development for the quality of service and quality of experience Which is standardized inside ITUT and I would like to give the floor to Jens to introduce us to this interesting topic Thank you Welcome everybody. Have a nice afternoon and I hope it is not becoming too technical I will try to give you a brief overview about our parts here on ITUT, especially QEQS We are very active in ITUT 30-Coop-12, 11, form of 30-Coop-9, 30-Coop-12, where I'm more or less there for almost 30 years now and If I would like to talk about those things in ITUT 30-Coop-12 I would focus on mobile network testing means mobile networks like cell phones or other wireless LAN Wi-Fi Of course, we are also active in ITUR and at the 3GP week back whatever you can imagine belongs to this Topics I am for myself. I have for almost 20 years now a robert worship in 30-Coop-12. It's a bit Let's say maybe unknown to most of you perceptual-based, objective, audio and visual Quality measurements. It means how to measure how a human subject would Perceive voice audio. Does it sound well? That's down to create it. Do you see distortions on the screen from a video or third things? We are also in touch with a relation guidelines network performance measurements It means how performant is a network from the view of an end user of a customer. We said a lot of Active contributions IPR standards. Maybe you know that Bojaka is the standard for speech quality or Other ones for video quality measurements. This is all 30-Coop-12 You may ask you why we as Rotary Schwartz are here in ITUT doing standards I think international standards are essential for interoperability In and between telecommunication networks and services and they guarantee valid and true measurement results all over the world They apply to industry telecommunication network operators. We have Customers like authorities, regulation authorities in individual countries For us is a clear focus of Implementing approved and some of our measurement method. The same as sharing our experience to others and drive civilization actively forward. If you have a look to a Network lifecycle from spectrum clearance from Network engineering from deployment Monitoring benchmarking. We are serving all the individual aspects of this lifecycle We have a solution platform which is putting probes in the network to data collection And can do data analytics at the upper layer as well And we do it through all of the individual layers down from playing physical spectrum as you may be there to radio transport Transport layers like IP or TCP UDP up to quality of service and quality of experience Let's maybe I hope it's not becoming too technical 5g everyone that talks about 5g what is 5g 5g is Not a revolutions maybe an evolution from 4g. It is coming on stepwise. It is a transition What you will have is new spectrum. You have maybe heard about millimeter waves very high frequencies to especially to have coverage in indoor equipment in indoor sites or in Very narrow Environments you have massive mime and beam forming means the network is able to direct the energy to you to your mobile We have multi connectivity. You can combine 5g and 4g And make use of all frequencies you have the same as you have a virtualization of the network It means you have a flask fix the physical layer you conserve individual customers with individual QS parameters This is all great But spectrum in the radio is just the first step. How is the technical performance and real field? This is very important Look, I have the best spectrum ever if you cannot make use of it by high bitrate by short latency by reliability Or how is the experience performance by a user? How is voice of a new radio? How does it sound? How is the video is it going? How is the online game going? how it works with your reality and For this We have a test solution, but this is the complete new game if you have a look to the day today networks are made for Downloading data in masses. No one cares about latency or short transportation time Focus is on doubt data download if you imagine you browse to download emails you do whatever tick tock You just need a data pipe which is powerful enough For 5g is changing You have interactive in real-time applications like virtual reality Outmanid reality. We have new players Automotive industry so for zero. We have non-smart phone devices in the network light modems like your Rich talking to the internet or whatever We have open one. It means you can combine components from different vendors together and focus is data rate and extreme short transport latencies if you have a long latency you cannot do a video chat You cannot do virtual reality nothing will always see a leg latency in between what you're doing in the response from the network And to make it simple 5g is bit weight continuity and latency Demands are different, but you have to take care about all three not about Bit weight only and For this we have just a small selection there. You see all the individual Measurement device groups here. We are we're having for supporting this spectrum clearance interference hunting troubleshooting site acceptance New radio network measurement solutions you see here a smart phone based Solution that we have all the measurement algorithms running on the smartphone itself and for data analysis I Platform where you can even see where you have measured where you have been driven around or walked around is your measurement device And you can do all the performance measurements in a very efficient way okay, thank you and Enjoy the rest of the afternoon. Thank you
