The road to 5G

3

5G will cover new use cases and requirements

BB access in dense areas

• Seamless

experience

• f

connectivity anytime, anywhere, on any access technology

• Video services, possibly empowered by 3D and

Augmented Reality

BroadBand access everywhere High user mobility

• High user mobility on trains, while still enjoying HD movie
• r work in a videoconference

+50Mbps everywhere

Speed up to 500Km/h Up to 1 Gbps

4

Use cases and requirements

Extreme realtime communications

• Ultra low power, integrated sensors, e. g. wearable

to measure various heart rate or blood pressure, …

• Real-time sensing, data delivery, big data intelligence

and real-time actuation to enable Tactile Internet

Massive IoT Emergency & Safety

• Public Protection and Disaster Relief e.g. especially for

communication among authorities and citizens

Connection density: 200.000 /km2 < 1ms latency Resilience & High Availability

5

Use cases and requirements

Broadcast like services

• Monitoring patients & fast medical treatment.
• Vehicles

realize critical situations fast, react accordingly and alert other cars…

• Information distributions in areas such as arenas,

event locations, city centers, city metros

Ultra-reliable communications < 1ms latency Ultra High Availability One-to-Many transmission capability

6

Business Models

The Operators’ value proposition may leverage on new / relevant business models – particularly those related to new services (retail and wholesale) Connectivity provider Asset provider Partner service provider

• Basic

connectivity

• Enhanced

connectivity

• XaaS: IaaS, NaaS,

PaaS (wholesale)

• Network sharing

(cost savings)

• Operator offer enriched by

Partner (retail)

• Partner offer enriched by

Operator (wholesale)

What is 5G?

An extremely flexible and highly programmable e2e system, application, customer, time and location aware Serving at best high diversity types of communications (Human & Machine) with different performance attributes Natively leveraging NFV technologies:

►

Support on demand composition of network functions and capabilities

►

Enforce required capability/capacity “where and when needed”

Profitably accommodating low- and high-ARPU traffic and sustainability thanks to cost saving and new business opportunities Being future-proof and ready to serve even not yet identified use case and radio technologies

8

Key issues to reach 5G

Spectrum Architecture & Operations Air interface

9

5G Common composable network

 Use case driven creation of dedicated networks optimized for specific service scenarios / customers (network slices)  Combination of functions available in a catalogue, through the NFV Orchestration Platform

Only virtualisation can allow the needed flexiblity and sustainability

Standardization phase Deployment phase

5G

Mobile lifecycles: from early studies to standard

Is it too early to work on 5G?

• Major technology shift

roughly once every 10 years.

• Standardization

usually starts 4-5 years before the first commercial launch of a new generation

• R&D activity usually

starts 2-3 years before proposals come to standards…

Mobile connections (in millions)

5000 3500 2500

• Approximately 20 year-

cycle from launch to peak penetration

Key Issues

Low latency Programmable & flexible network Handover from 5G to 2G/3G? CS Fallback for 5G IMS voice? USIM vs softSIM? Connectivity for drones Wide area sensors Industrial control Which services from earlier generation? Lifeline communication

NFV,SDN, MEC….++

Software will have a key role in the 5G Convergent Network

What else? Softwarisation

• Mobile Fronthaul: another aspect
• f Softwarisation
• C-PRI, ETSI ORI, projects as i-JOIN

are defining the radio side and the functional splitting

• Figures are somehow worrisome

What else? Fronthaul and backhaul evolution

• ITU-T natural home for the fibre network

aspects

• Collaboration is needed with the radio and

mobile architecture groups to assure compatibility and best efficiency of the solutions

15

Future networking: will IP still satisfy the 5G performance requirements?

What else? New Networking

Requirements on delay and reliability could in some cases be not easy to meet in classic IP networks Replace? Relay ? Integrate? New concepts as ICN, CCN….
