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 laterNews on ‘5G-pilots’, …UK, Dresden – and outside EU: Korea, China, Japan, …

US / IEEE remains silent, via WiFi-path development of 5G-technology

“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?

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?

VISION ON 5G (NGMN)

5

“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


‘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 chirurgical-

operations

REQUIREMENTS

User experience

System performance

Enhanced service

New business enabling

Network deployment, operation and management

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


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


DENSIFICATION

Why is densification important?Micro-servers / ‘from cloud to fog’Wireless backhauling via mesh-network becomes feasibleTrend in wireless is to provide more bps/m3

more spectrum, more spectral efficiency (e.g. MIMO)most important measure is ‘architectural’, i.e. densification

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 systemsLarge 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 systemsHuge 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.

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.

APPLICATIONS FOR Gb/s

SELF* / COGNITIVE NETWORKING

Why is self* important?Network management is a costly affair for mobile operators: it accounts for ~20% of OPEXFuture roll-out increasingly based on effort by citizens / customers –i.e. non-professionals � plug-and-play / self-configuration becomes more importantSuccess 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


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’
