2 METIS Scenarios and Test Cases Amazingly fast Great service in a crowd Best experience follows you Super real-time and reliable connections Ubiquitous things communicating Dense urban information society Virtual reality office Shopping mall Stadium Open air festival Mobile cloud processing Traffic jam Blind spots Teleprotection in smart grid Emergency networks communications Traffic efficiency and safety Massive deployment of sensors and actuators Source: METIS Deliverable D1.1 Scenarios, requirements and KPIs for 5G mobile and wireless system, Additional use cases has been proposed by NGMN Alliance, NGMN White Paper, Feb (available online

3 Recap: ITU-R Vision for Systems Beyond 3G Source ITU-R M.1645 Integrate existing and evolving access systems on a packet-based platform to enable cooperation and interworking. Optimally connected anywhere, anytime" Dept. of Electrical Engineering, Communication Systems Slide 3

4 Network Flexibility versus Efficiency - We have already done it once on the terminal side! Picture source: Dept. of Electrical Engineering, Communication Systems Slide 4

5 Standalone mm-wave Networks - From hexagonal cells to dense unstructured narrow beam spaces Source: mmmagic WP4 presentation, ETSI workshop, Sophia-Antipolis, Jan 28, 2016 Calls for integrated computing and communications to meet stringent delay and energy efficiency requirements. Dept. of Electrical Engineering, Communication Systems Slide 5 5

6 Network slicing in self-backhauled mm-wave Networks - Where should we do the computing? Dept. of Electrical Engineering, Communication Systems Slide 6

7 Challenges and Opportunities with Demanding Verticals Integrated Moving Networks New opportunities Mutual benefits! Better mobile systems efficiency: Vehicles collect side information to improve the resource allocation and performance of the mobile network More reliable V2X links: Connect non-vehicular users to the Traffic Safety/Traffic Efficiency protocols (Pedestrians, cyclists, pets, ) New disruptive business opportunities: exploiting vehicle sensed data 7 Dept. of Electrical Engineering, Communication Systems Slide 7

8 Introductory Statement on the Overall Panel Questions 1. What are some moonshot use cases for driving mmw research and technology? High data rate and low latency driven use cases Potentially small form factor devices tight on-chip integration 2. What are some moonshot technology requirements for driving mmw research? Standalone and self-organizing mm-wave networks with multiple network players 3. How can academia and industry collaborate to leverage the new NSF PAWR (Platforms for Advanced Wireless Research) program to deliver moonshot advances? Collaborate with European and Swedish research programs! Dept. of Electrical Engineering, Communication Systems Slide 8

9 Panel Questions What use cases will drive the next generation of mmw wireless technology and network expansion? Can you think of any application / use cases that right now would look remarkable like a moonshot. Ambient intelligence/augmented reality based applications Possible use cases include: Further increase of common wireless applications we use today such as video, web browsing, Connected car: autonomous driving, media download, sensor data fusion. VR / AR Robotics Telepresence Cloud / edge computing Others?: Massive IoT towards Ambient Intelligence In the context of cloud computing, there is always a choice between local and remote computing. While wireless connectivity will improve, so will the computational processing and storage capabilities of devices. Which trend will dominate? We will need both. Ideally we should pre-process as much data as possible at the source before sending it through the network. Can we imagine the use cases now? Is that the way we should drive research? Can we trust that if we provide data, it will be used? Based on our previous experience: No. What are the devices of the future? What will be connected?: Anything that wants to be connected will be connected, unless we will face a privacy/energy/electronic waste consumption crisis. Smartphones Wearables Machines, robots? Dept. of Electrical Engineering, Communication Systems Slide 9

10 Panel Questions Let s be more bold. Wireless is about connectivity of devices and people. Imagine yourself as a science fiction writer. If technology was not an issue, how would people interface with devices, the cloud, and other people?: Ambient intelligence, information, knowledge and skills would be available as a good friend. What are the technical requirements for these applications: All of those listed and Integrated security and privacy solutions. Latency Data rate Numbers of devices Power consumption Can we think of specific technical goals to strive for (e.g. capacity of x Gbps, y latency, )? Scalability of the solutions in terms of complexity, energy efficiency and distributed/decentralized self-organized solutions. What are the technological areas that we need to concentrate on? What are the real bottlenecks in achieving this vision: All of those and convergence of computing and communications. New user interfaces? Power consumption? Air interface Network density / infrastructure. Which of these are simply business rather than engineering challenges.: It will be a mix of both. What skills / expertise will be needed for developing the future wireless technology? How should we be training students?: Converge computer science and communication/information theory and hardware. What companies have the right assets / expertise to succeed. Will new players (e.g. Google, Facebook, cable providers) play a growing role?: Yes, companies like Google and Facebook will play an important role, unless governmental requirements on privacy will disrupt. In general, I think there will be a need for new services like personal information management and protection. Will wireless become like a utility? Yes, but integrated in services.
