The road to 5G

3

5G will cover new use cases and requirements

BB access in dense areas

Seamless experience of 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 or 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

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

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

► Not only improved performance (or «doing better» what we can do today…)

What’s different from 4G?

► Multi RAT

► LTE-Advanced for macro coverage

► New RAT enabling new business

► Higher data rate & lower latency

► New design principles for

cost-effective deployment

Beyond the usual x10, x 100, x 1000 improvements…

► Resource elasticity: dynamic allocation

of functions, processing and memory

resources based on application requirements

and load consumption over time/space

► Greater cost efficiency to support

IoT business: simplified network to be

tailored for different types of users

Key issues to reach 5G

Spectrum

Architecture & Operations

Air interface

11

From sub-GHZ to mm-wave

Lower frequencies to be used for macro-area

coverage, included deep indoor

Higher frequencies to be used in a complementary

approach for extreme traffic capacity in dense

scenarios

Spectrum framework evolution

12

Innovative deployments

► Mesh networks

► Massive use of direct communication

Virtualized access network with base band pooling

(towards Virtual – RAN)

and radio access dynamic re-configuration

New radio Access components

► New Radio interface (FBMC for example, addressing also low

cost M2M);

► New duplexing modes (i.e. full duplex)

► Ultra-lean signalling

Reinforce LTE-A techniques

► Network densification and HetNet

► Massive MIMO (>> than 8x8 antennas)

► Advanced receivers and interference coordination

► Enhanced multi-RAT coordination

► Wireless back/fronthaul; enhanced fronthaul (innovative

split BBU-RRH)

Technologies for flexible use of spectrum

► Use of frequencies above 6 GHz (up to 100

GHz)

► Opportunistic access to spectrum, including

use of unlicensed bands

Candidate radio access technologies for 5G

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
