5G: The Software Network and Virtualization Opportunities

J-L. Beylat, VP European programs , Bell Labs, Alcatel-Luc

Challenging scenarios

WHAT ARE WE TRYING TO BUILD ?

THE HIGHEST PERFORMANCE NETWORK ?(BW, Latency, Availability, Programmability)

THE LOWEST COST PER BIT NETWORK ?(Capex, Opex, inc. Energy)

3


THE MOST PERSONALIZED NETWORK ?(User-optimized, Predictive, Sentient…?)

ALL OF THE ABOVE … BUT WHY?

Hierarchy of Human Needs

(Based on Maslow To acquire status and

And knowledge &

wisdom

To allow time to

appreciate life

And feel that we have

achieved something

And help others

achieve too

TO SERVE HUMAN NEEDS

4


(Based on Maslow

Model)

And connect, communicate

& collaborate

Securely

To acquire status and

respect

To live…

WE NEED TO BUILD THE NETWORK OF YOU … THAT

Allows you to connect, communicate and collaborate with…

PEOPLE PLACES POSSESSIONS

Creates time … …by creating a virtual you

WE NEED TO BUILD THE NETWORK OF YOU … THAT

… but how and when ?
