ETSI's Summit on Sustainability: ICT Standards for a Greener World

The ETSI Summit on Sustainability - How ICT developments and standards can enable sustainability and have a positive impact on society, took place on 30 March 2023 and focused on the key role of the ICT industry and related standardization activities to support Green initiatives. The event brought a large and global audience of over 220 stakeholders including operators, solution providers, policy makers and standards bodies or fora working on the topic.

A multitude of presentations including two interactive panel sessions, rhythmed the day and succeeded to make it a highly interactive Summit, pointing out challenges and how ICT can be both the problem and the solution.

The opening session examined the sustainability challenges and global green initiatives from numerous global standards bodies and fora. One of the suggested actions was to adopt ESG (Environmental Social Governance) goals as an integral part of the company’s objectives. Another highlight from the session was the need for standards work on the measuring and reporting of “avoided emissions,” that is being covered by ongoing work in ETSI. Feedback from the audience pointed out that it would be beneficial to further investigate the balance of ICT deployments vs real needs. Do we really need to endlessly deploy new technologies, when exiting ones serve the need?

The following are presentations from the welcome address and session 1:

• Welcome Address by Luis Jorge Romero, Director General, ETSI
• SESSION 01 - The Sustainability Challenge and Global Green Initiatives chaired by Bettina Funk, ETSI GA Chair: The session examines several regional and global initiatives working on sustainability and seeks to identify synergies and areas of cooperation.
• Some Standardization Needs for Green Digital Twin Transition by Emilio Davila Gonzalez, European Commission
• ITU Sustainability & Working with ETSI by Dominique Wurges, ITU-T SG5  
• IEC Sustainability & Working with ETSI by Alfonso Sturchio, IEC TC111 
• ISO/IEC/JTC1 Sustainability & Working with ETSI by Thomas Wegmann, Liaison officer ISO/IEC JTC 1/SC 39
• The work of GeSI toward Energy Efficiency (and other sustainable technologies) by Luis Neves, GeSi
• Green Future Networks by Anita Doehler, NGMN Alliance

The second session focused on the role of ICT in sustainability and was animated by two panels. The first one addressed the operators’ objectives and their plans for sustainability. The second one dealt with various initiatives being taken by solutions providers to meet the needs expressed by the operators and society as a whole. Suggested actions emerging from the debate included putting sustainability criteria in the procurement phase towards the vendors and enhance collaboration between operators, to share their common requirements and provide them to the supply chain ecosystem. In an animated exchange between the Panellists and the audience it was highlighted that there is an urgent need to reduce energy consumption, extend the lifecycles of ICT equipment and systematically recycle and repurpose in order to reduce ICT waste.

The following are presentations from session 2:

• Session 02 - The Role of ICT in Sustainability: The session comprises two interactive panel sessions examining 1) Operators objectives and plans for Sustainability and 2) several initiatives being taken by solutions providers to meet those objectives. Session Chaired by David Boswarthick, ETSI
• Operators Panel Moderated by Anita Dohler, NGMN Alliance e.V.: The purpose of this panel is to examine what are the sustainability plans, challenges & priorities for Operators
• Saima Ansari, Deutsche Telekom
• P. Balaji, Vodafone Idea
• Marc Grant, AT&T
• Luca Pesando, TIM
• Solution Providers Panel Moderated by Joe Barrett, GSA, Global Mobile Suppliers Association - The purpose is to examine what the current solutions and remaining challenges on Sustainability are.
• Howard Benn, Samsung
• Raffaele Bolla, 6Green Project
• Ralf Bucksch, IBM
• Susanna Kallio, Nokia

The afternoon opened with an  overview of ETSI, 3GPP and oneM2M activities supporting technologies for sustainability. One of the presentations highlighted that ICT should initially focus its own environmental impacts and consider digital sobriety as it is recognized that the cleanest energy is the one that is not consumed.

The following are presentations from session 3:

• Session 03 - ETSI Activities Supporting Technologies for Sustainability Chaired by Nick Sampson, ETSI OCG Chair: This session will present the sustainability standards work that is ongoing in ETSI and our Partnership Projects oneM2M and 3GPP.
• TC EE’s Approach to Sustainability by Benjamino Gorini, TC EE Chair 
• The Work of TC ATTM and OEU for Green and Sustainable Networks and Cities by Lynn Reiner. TC ATTM TM6 Chair
• 3GPP’s Approach to Energy Efficiency by Jean-Michel Cornily, Rapporteur for 3GPP EE work items
• oneM2M Work on IoT for Sustainability by Dale Seed, Chair oneM2M SSC 

The summit concluded with a dynamic exchange around what more telecoms can do to move forward in the right direction. ICT and specifically data centres create a significant carbon footprint, and there was a call to use the ISO Net Zero guidelines in order to develop sustainable strategies. The industry should adopt an eco-design (sustainability by design) approach and seek to have products that are energy efficient, with longer life cycles, recyclable and repairable.

The following are presentations from session 4:

• Session 04 - What More Can Telecoms Do to Ensure Global Sustainability Targets are Reached? Chaired by Dirk Weiler, ETSI Board Chair: This session will address alternative perspectives on the principle challenges and gaps that need to be urgently addressed. What more can be done, both in ETSI and beyond, and what could be future directions/actions for the industry?
• Environmental Impact of ICT – Data Centers by Bruno Lafitte, ADEME
• ISO Net Zero Guidelines – a Global Basis for Net Zero Action by Emily Faint, BSI
• ECOS: Driving Environmentally Friendly Standards, Policies and Laws by Mathieu Rama, ECOS

As a conclusion it was agreed that ICT is part of the sustainability problem and must seek to reduce its own emissions, whilst at the same time ICT is certainly part of the solution and should be applied to other domains in order to help them reach their own sustainability goals. As a first step, making ICT more sustainable should be the #01 priority for the industry today and ETSI groups TC EE (environmental engineering), TC ATTM (access, terminal and multiplexing) and ISG OEU (operational energy efficiency for users) are currently providing the standards to enable this transition to greener digital technologies.

ITU-NGMN Joint Conference on “Licensing practices in 5G industry segments"

IPR, Licensing and royalties are always an interesting topic. In the end they decide what price a device would be sold at. If I put it simply, the cost of device = cost of manufacturing + marketing + sales and distribution + support and insurance + profit + IPR. The licensing cost is often added in the end as it could be applicable on the selling price of the device.

Ericsson willing to halve its royalty rate for 5G smartphones to $2.50 per device from $5 to accommodate needs of markets such as India, Nokia likely to charge $3.50 royalty per 5G handset, while Qualcomm will charge up to $16.25 in royalties. #IPR #Patenthttps://t.co/cgZQbiwFft

The above tweet is interesting as it lists out the IPR costs by major patent holders. I wrote a post earlier detailing the 5G patent holders here. Since then this have moved on significantly. In addition to the royalty charged by the 5G patent holders (it also includes legacy technologies like 2G, 3G, 4G &Wi-Fi), there are patents for messaging, Codecs (seperate for audio / video), etc. To be fair it's a complex process. This is why I sometimes get shocked when I see 4G smartphones selling for £20 ($25).

Coming back to the conference, all the presentations are available on ITU page here.

Sylvia Lu, who wears many different hats including one for CW, UK5G and uBlox and a friend of 3G4G blog was one of the speakers at this conference. Here is a tweet on what she had to say about this event:

Beyond the hype is the licensing practices to ensure 5G adoption is FRAND and work for the new 5G ecosystem incl. the verticals for 5G to scale. Many thanks for the invitation @NGMN_Alliance @itu Delight to present on behalf of @ublox@UK_5G @cambwireless https://t.co/sjwZzkN2dD pic.twitter.com/kNtjPSuKzi

For those who may not know, FRAND stands for Fair, Reasonable, And Non-Discriminatory. Wikipedia has a nice article explaining it here.

NGMN Press Release on this conference mentions the following:

The Next Generation Mobile Networks (NGMN) Alliance has jointly organised and executed a successful conference on Licensing Practices in 5G Industry Segments with the International Telecommunication Union (ITU), bringing various experts from around the world together to discuss licensing practices and challenges of 5G.

The conference featured moderators and speakers from some of the biggest names in telecoms, including AT&T, Deutsche Telekom, NTT DOCOMO, Orange, Ericsson, Nokia and Microsoft. Also in attendance were key stakeholders of vertical industries, including Audi, Bosch, Panasonic and u-Blox, and patent pool administrators, namely Avanci, MPEG-LA, Sisvel and Via Licensing, who co-sponsored the event, the European Telecommunications Standards Institute (ETSI), the Japanese and the European Patent Offices, and the European Commission.

Focusing on the development of 5G and the Internet of Things (IoT), the conference facilitated sharing and discussing of present-day licensing practices and related issues across different industry segments.

A host of insightful sessions took place igniting an inclusive exchange on:

• Patent licensing practices with interactive discussions that focused on issues stakeholders need to be aware of.
• Sharing licensors’, licensees’ and pool administrators’ requirements on patent pools/platforms.
• Identifying proposed practices and conducts for licensors and licensees.
• Listing requirements for increasing transparency and assessing essentiality of Standard Essential Patents declared to Standards Developing Organisations.

“It’s great to notice that our joint ITU-NGMN conference has been such a success,” said Dr. Peter Meissner, CEO of NGMN. “Obviously, the 5G Eco-System is different. New use cases beyond mobile broadband - like massive IoT as well as highly demanding requirements from vertical industries on low latency, ultra-high reliability and security - are causing substantial network transformations. All these challenges have implications on the intellectual property of mobile network operators and across the different industry segments. Conferences like this are key in identifying IPR issues and exploring solutions for the enlarged eco-system.”

Small Cell Backhaul Solution Types

This is from a presentation by Julius Robson of CBNL, representing NGMN in the Cambridge Wireless Small Cells SIG event.

Interesting to see all possible options for Backhaul for small cells.

Two interesting NGMN papers on Backhaul

There are some interesting blog posts on Broadband Traffic Managemenet on Backhaul. Here are few excerpts:

Traditional network management practice says that network element usage level should not exceed 70% of its capacity. If it does - it is time to do something - buy more or manage it better. So, according to a recent Credit Suisse report - it is time to do something for wireless networks, globally. For North America, where current utilization at peak time reaches 80% it is even urgent.

Phil Goldstein (pictured) reports to FierceWireless that - "Wireless networks in the United States are operating at 80 percent of total capacity, the highest of any region in the world, according to a report prepared by investment bank Credit Suisse. The firm argued that wireless carriers likely will need to increase their spending on infrastructure to meet users' growing demands for mobile data .. globally, average peak network utilization rates are at 65 percent, and that peak network utilization levels will reach 70 percent within the next year. .. 23 percent of base stations globally have capacity constraints, or utilization rates of more than 80 to 85 percent in busy hours, up from 20 percent last year .. In the United States, the percentage of base stations with capacity constraints is 38 percent, up from 26 percent in 2010"

And

The Yankee Group provides the following forecast for mobile backhaul:

Average macrocell backhaul requirements were 10 Mbps in 2008 (seven T1s, five E1s). In less than three years, they have more than tripled to 35 Mbps in 2011, and by 2015, Yankee Group predicts they will demand 100 Mbps.

There were 2.4 million macro cell site backhaul connections worldwide in 2010, growing to 3.3 million by [2015?]

Yankee's new research conclude:

"The market for wholesale backhaul services in North America will grow from $2.45 billion in 2010 to $3.9 billion in 2015, with the majority of this growth coming from Ethernet backhaul. Successful backhaul service providers will be those that can demonstrate price/performance and reliability, have software tools in place and can meet the specific needs of the mobile market.

And recently:

A Dell'Oro Group report forecasts that "Mobile Backhaul market revenues are expected to approach $9B by 2015. This updated report tracks two key market segments: Transport, which includes microwave and optical equipment, and Routers and Switches, which includes cell site devices, carrier Ethernet switches, and service provider edge routers .. routers and switches expected to constitute 30% of mobile backhaul market "

Shin Umeda, Vice President of Routers research at Dell’Oro Group said: “Our research has found that operators around the world are concerned with the rate of mobile traffic growth and are transitioning to Internet Protocol (IP) technologies to build a more efficient and scalable backhaul network. Our latest report forecasts the demand for IP-based routers and switches will continue to grow through 2015, almost doubling the market size of the Router and Switches segment in the five-year forecast period”

I have some basic posts on why Backhaul is important, here and here.

NGMN has timely released couple of whitepapers on the Backhaul.

The first one, 'Guidelines for LTE Backhaul Traffic Estimation' document describes how a model is developed to predict traffic levels in transport networks used to backhaul LTE eNodeBs. Backhaul traffic is made up of a number of different components of which user plane data is the largest, comprising around 80-90% of overall traffic, slightly less when IPsec encryption is added. These results reveal that the cell throughput characteristics for data carrying networks are quite different to those of voice carrying networks.

The purpose of second one, 'NGMN Whitepaper LTE Backhauling Deployment Scenarios' is to support operators in their migration from current architectures to new, packet-based backhaul networks. With the introduction of LTE operators need to look at how the backhauling network, the network domain that connects evolved NodeBs (eNBs) to MME and S/P-GW, is capable of adapting to the new requirements, namely the adoption of a packet infrastructure, without disrupting the existing services. This paper introduces some reference architectures, moving from a pure layer 2 topology to a full layer 3 one, discussing some elements to be considered in the design process of a network.

They are both long but interesting read if you like to learn more about Backhaul and the best way in future proofing the network deployments.

NGMN Top 10 Operational Efficiency Recommendations

Setting up and running networks is a complex task that requires many activities, including planning, configuration, Optimization, dimensioning, tuning, testing, recovery from failures, failure mitigation, healing and maintenance. These activities are critical to successful network operation and today they are extremely labour-intensive and hence, costly, prone to errors, and can result in customer dissatisfaction. This project focuses on ensuring that the operators’ recommendations are incorporated into the specification of the 3GPP O&M (and similar groups in other standardisation bodies) so that this critical task moves towards full automation.

The overall objective is to provide operators with the capability to purchase, deploy, operate and maintain a network consisting of Base Stations (BTS) and “Access Gateways (AGw)” from multiple vendors. The NGMN project Operational Efficiency OPE has taken the task to elaborate solutions and recommendations for pushing the operational efficiency in NGMN networks and has produced recommendations on standards and implementations. The NGMN OPE project also influenced strongly the setup of a TOP10 document reflecting main recommendations in operational area. This document (embedded below) binds these two sources which are anyhow strongly linked together into one common NGMN recommendation document.

Operator Top Ten Requirements for the networks

Operation Requirements for next generation multi-technology networks are the key topic that brought 3GPP, NGMN and TM Forum together for a workshop held March 29-30 2010 in Bonn. The two-day workshop was attended by forty industry experts who worked on use cases and requirements in three parallel work streams and provided recommendations for next steps.

At the Bonn workshop, the 3GPP Telecom Management working group - SA5 - presented background data on the SA5 work program to date, much of which meets the needs of the NGMN Top Ten Requirements:

• Quality and Quantity of Alarms
• Automatic Software Management
• Energy Saving
• LTE Automatic Neighbour Relation (ANR) and Self Organizing Networks (SON) Operation
• Performance Management in Real-time
• Substitution of Monitoring Probes by Infrastructure Inherent Trace Functionality
• eNodeB Plug & Play Self-Commissioning
• OSS Standard Itf-N
• LTE Parameter Optimization
• Automatic Inventory

The workshop conclusions acknowledged that:

• Standards specified by SA5 over the last ten years provide a widely deployed, fully re-usable and expandable solution for management of Next Generation Networks,
• NGMN Top Ten Requirements are mostly satisfied already by 3GPP SA5 specifications, the missing functionalities will be addressed in 3GPP Release 10 (due December 2010),
• The ongoing 3GPP-TMF alignment program provides an excellent opportunity to address network management of Wireless-Wireline convergence based on the 3GPP IRP framework.

At the end of this workshop, the SA5 Chairman Christian Toche said:

"This workshop has identified important requirements and allowed TMF and 3GPP to compare their solutions that can satisfy Operators requirements, of whom many are already supported in 3GPP specifications. I am confident that, as long as the representation from each group is maintained at the right level, an alignment of the 3GPP and TM Forum specifications will result from this cooperation, satisfying the requirements for use in convergent network operational environment."

Christian Toche identified that the next step includes the need for the two ongoing Network Management harmonization projects with the TM Forum - On FM and resource modelling - to be completed.

Further progress on the alignment of 3GPP and TMF specifications will be made at the follow-up workshop on May 6-7, 2010 in Montreal

NGMN put into our context

Here is a slide from Klaus-Jurgen Krath of T-Mobile Germany, which simplifies NGMN for us. NGMN or the Next Generation Mobile Networks intends to complement and support the work within standardisation bodies by providing a coherent view of what the operator community is going to require in the decade beyond 2010.
