1 5G NEW CHALLENGESFOR INDUSTRYANDRESEARCH BUT WHO ARE THE CHALLENGERS? Prof dr ir Erik Fledderus TNO principal scientist TU/e architect CWT/e Trends Transitions TNO

2 INTRODUCTION Anecdotal: 2002, 4G is its infancy, invitation from NTT DoCoMo for a one-day session on 4G who is your 4G-business consultant? demonstrations in labs of underlying technologies Now, 12 years later News on 5G-pilots, UK, Dresden and outside EU: Korea, China, Japan, US / IEEE remains silent, via WiFi-path development of 5Gtechnology Europe teams up in 5G-infra PPP (KIVI dec 2013) and joins forces met Korea; NGMN 5G white paper tries to channel efforts of vendors, as they did with 4G / LTE Where do the Dutch stand?

4 STORY LINE TNO / TUE: active within NGMN (advisor) TNO member of 5G PPP; board member for M2M (Toon Norp) track record in the area of SON in LTE (Advanced) and new spectrum policies; active in 3GPP and ETSI 1. Massive challenges (throughput, latency reduction, sensing, resilience, safety/security, fractal heterogeneity) but who are the challengers? 2. Which components are expected? 3. Where do the Dutch stand? 4

5 VISION ON 5G (NGMN) 5G is expected to be an end-to-end ecosystem that supports the new use cases in the connected society, supporting new business models within the same context and empowering the Operators value proposition within the same context Possible business models for MNOs: Asset provider Partner service provider 5

6 TACTILE INTERNET Coined by Gerhard Fettweis One of four physiological interactions (muscular, audio, video) Tactile interaction refers to a system that has a tactile input but audio and/or visual feedback. Examples: Interaction with content as if it was local, like dragging objects on a touch screen Real-time collaboration and immersion at-distance, such as chirurgicaloperations 6

9 REQUIREMENTS User experience System performance Enhanced service New business enabling Network deployment, operation and management 9

10 SOME INTERESTING REQUIREMENTS Take a few examples related to use case of tactile internet, or Dutch strengths: Near-zero latency (1) ~ tactile internet Device power-efficiency (1) techn universities Spectrum efficiency (2) spectrum policies Context awareness (3) cognitive networking Operation efficiency (5) self-acting 10

11 SOME IDENTIFIED TECHNOLOGY COMPONENTS Many technology components are already present for some time (cf. hype-curve) Examples: flexible use of spectrum (licensed and unlicensed) densification interference coordination big data / context-awareness cognitive radio 11

12 DENSIFICATION Why is densification important? Micro-servers / from cloud to fog Wireless backhauling via mesh-network becomes feasible Trend in wireless is to provide more bps/m 3 more spectrum, more spectral efficiency (e.g. MIMO) most important measure is architectural, i.e. densification 12

15 SPECTRUM POLICIES SDR Flexible use of licensed spectrum / integration of unlicensed spectrum SDR / cognitive radio three (Dutch) scenarios: Program Making and Special Events (PMSE)/low latency systems Large number of wireless microphones, webcams, headsets etc. during an event. The individual wireless links might need only relatively little bandwidth, but it should be available 'continuously' for at least several minutes. A low latency is a must in this application. Sensor & control systems Huge numbers of both sensors and actuators to monitor and control the environment. Integration can lead to very small nodes, often called smart dust. (Ad-hoc) networks at events that result in high system-capacity needs and scalable internet access. Event-based scenarios with very high user densities and a large demand for wireless communications, like sports events and concert events. 15

16 SPECTRUM POLICIES (SUB)MM WAVES Exploring new territories mm and sub-mm waves (60 GHz and terahertz) new materials and manufacturing methods are deployed, like GaAs and RF MEMS. new concepts like system-in-package and new 3-dimensional antenna-array architectures. 16

19 SELF* / COGNITIVE NETWORKING Why is self* important? Network management is a costly affair for mobile operators: it accounts for ~20% of OPEX Future roll-out increasingly based on effort by citizens / customers i.e. non-professionals plug-and-play / self-configuration becomes more important Success of Internet-of-things is substantially influenced by costs of deployment embed intelligent matter in bulk (paint, sand, ) Cognitive cockpit local decisions aiming at global performance ~ swarming, requires software defined sub-modules, combination of learning capabilities ( blank sheet ) and pre-defined use-cases Role for big data analytics 19

20 FINALLY: WHERE DO THE DUTCH STAND? Dutch research groups at Technical Universities do not profile themselves in telecom standards Even though they work on key-component technologies (low-power, sensor/m2m networks, transceivers for SDR, 60 GHz, MIMO, ) Some experts are active in IEEE working groups TNO is active and presents itself actively in standardisation and fora (such as 3GPP, NGMN, ETSI), but on a limited number of areas Do we dare to name use-cases and frame them as pre-5g experimental testbed for 5G technology? Use-cases with strong users, and a supporting stakeholders (part of the eco-system is present) Pilot to succeed not to give it a try 20
