PresenterPresentation NotesUse the animation to show todays network and limitations. This will then progress to the various advantages that the 5G revolution will provide:
Todays Network:We are all using this today. Mobile data is a very real addition to the 2G and early 3G networks. It also works wellsome of the time. Who here is always happy with the coverage, speed, and reliability of their current mobile device?We switch between WiFi and Cellular but it is often clumsy and we have to be aware of which system we are usingIn many cases, operations at cell edges or in a large crowd are unreliable at best and simply do not work at the worstTodays system is reported to consume 2% of the worlds total generated electrical power
Tomorrows Network:Click #1: A massive increase in capacity driven by much smaller cells and more infrastructure will help manage service in a crowd. In this case, the crowd is served by multiple very small cells that are focused on where those people are.Click #2: The addition of millimeter Wave technology, previously only used in Radar, point-to-point, and aerospace defense systems, will allow for the 100X increase in data rates for key applications (typically video). This will be implemented with highly directional antennas and will provide the speed that the high-end data users will demand.Click #3: The new network has to support more things communicating in different ways. The car has now had a nomadic base station installed which is what provides one direction of communication to the user who is in a different cell. The user in the car now gets his communications through a small cell and the car itself is linked to the network for advertising, collision avoidance, and traffic guidance. Click #4: All of these innovative new approaches will not work without a redesign of the network topology. The computing engines will have to be centralized so that software can react to moving network capacity around the area; so that the speeds required over the air can be managed by the network, and so that we make the most efficient use of the network resources including power, spectrum, computing, and data capacity. The network will be driven by massive parallel computing platforms which will centralize the way that radio access works. Interesting approaches: today Mobile Association with a particular EnB is determined almost exclusively on best SNR on the downlink. But that may not be the best overall interference QoS for everyone, or SE, or EE. New Hueristics will be developed to ensure the best use of NW resources and still maintain the QoS and hopefully the QoE.

PresenterPresentation NotesMost importantly, this is an exciting time for us. Innovation will span from DC to Daylight and to improve capacity, efficiency, data-rates and speed, denser networks, and very complex interoperability challenges. 5G means we have to design much more energy efficient systems, new capabilities to use the communications spectrum we already use, expand our wireless access communications to mmWave, and even move our fiber-optic capability to digital speeds in the terabits/second. Not only will we get to help with all of these technical areas, we will be involved in the process from research to deployment with Design, Simulation, Calibration, Emulation, and Validation tools across this entire range of technical needs.
All of the new hardware and software you will be inventing will need testing. But before that, you will need to model and simulate these technologies as they are developed and as you work to make them work with each other. Today our team will describe to you some exciting new tools that will enable this early process.
I speak for Keysight and the entire industry in saying I look forward to this exiting time, not because of the new technology and business opportunities, but because we thrive in working closely with you all as market leaders.

PresenterPresentation NotesThis is summarized 4G and 5G technology roadmap for Electronic System Level simulation and T&M perspective aligned with 3GPP standard update and new 5G technology forecast.
PHY: Current 4G physical layer built in based on OFDM technique and has been faced with some technical limitations against 5G technical demands such as spectral efficiency and flexible spectrum access. Now, many multi-carrier based new waveform technologies (FBMC, filtered OFDM etc) has been studied to address this requirements.
Antenna: Low order MIMO technique applied in 4G standard is adapting higher order MIMO by adding more antenna elements. B4G is deploying full-dimension MIMO and 3D concept with elevation change of beamforming. 5G will have hundreds of array antenna elements at mmWave frequency.
Simulation: To address closed feedback loop and adaptive modulation and coding scheme for 4G, we needed special dynamic dataflow simulation technique. As future wireless communications need more antenna elements and complex signaling implementation, current simulation technology also need to be evolved equipped with accelerated simulation technique and robust handling of event driven simulation requirements.
Measurement: General purpose bench top instrument has been dominant position for cellular T&M market with some level of modular instrument usage by now. But, as new mobile product has more antenna channel, wider bandwidth and higher frequency, the instrument concept will also change toward modular based multi-channel, wide bandwidth, higher interface speed and real time capable.
Misc: 5G is not only revolution of mobile communications technology but also convergence of other network and service technology, many other technologies research have been conducted together.
