Because

Traffic will grow by 1000 within 20 years

All parts of the network will matter

All technologies we use in networks will matter

It makes ou uestion all as ects of the network

Why 1000x Network Efficiency?

It requires a highly scalable network

You cant solve it with power reduction alone

The goal should fit the problem

Green Policy & Standards Working Group

Charter approved April 2012 Initial activities for Green Policy and Standards Working Group:

Propose a set of key policy and standards initiatives as an initial focus for

the GreenTouch architectures, solutions and technologies, e.g. mobile

5G, terabit Ethernet, C-RAN, smart cities.

Identify and establish appropriate mechanisms with major Standard

Development Organizations (SDOs) and Policy Groups relevant to the

GreenTouch mission and objectives. Activities include, but are not

limited to:

Create a document that connects the GreenTouch roadmap with variousestablished policy initiatives such as EU 20-20-20 policy.

Work with other cooperating and partner organizations to ensure that futuredocuments, standards and policies, such as the ITU-T 2012 review, include

the necessary green and energy efficiency recommendations and provide

guidance for setting such policies.

ICT networks are growing rapidly

ICT and research communities are organizing to addresschallenges

Several promising research directions and initial results havebeen obtained

CONCLUSIONS

To go from research results to implementation in real networks

Collaboration between SDOs and forums to address a global issueshould be optimal

Too many overlaps ?

A partnership organization for energy efficiency related subjectsin standards?
