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:

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.

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:

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:

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.

Key enablers for mass IoT adoption

At 'The Things Conference' in Amsterdam in September, Roman Nemish, Co-Founder & President of TEKTELIC presented a critical view of different IoT technologies and argued that LoRaWAN is the only technology that will eventually make mass IoT possible.

The following is the intro to the talk from the conference:

IoT technology has progressed from home to city-scale applications, making it a crucial part of any operational process. IoT sensors are becoming more affordable, reliable, and easy to deploy.

The Internet of Things has already brought advancement to healthcare, retail, city infrastructure, and manufacturing with many other opportunities still open.

We are ready to explain why IoT deployment has transformed from privilege to necessity, what benefits it can bring to your business, and how you win the competition using IoT.

Enterprise IoT Insights have a good take on the talk here. The following is an extract:

Nemish, president at TEKTELIC, argued that new-wave cellular IoT – in the form of NB-IoT and LTE-M, primarily – is “too expensive” for consumers and too small-margin for mobile operators; that “most IoT opportunities are 10-25 times smaller [than the kinds of deals that would] attract operator attention”. Cellular IoT has “vast potential”, he concluded, but requires a “different approach”.

In other words, there is not enough profit in (low-power) cellular IoT for mobile operators to give it proper focus – and the deals are not big enough to make them really care. The IoT game – based on finely-calculated returns on volume-deals not going much higher than 100,000 units at a time – is better served by smaller-sized providers, without regional spectrum licences, offering broadly-equivalent technologies in unlicensed bands, he implied.

But experiences with Sigfox and LoRaWAN (in some formats) – the French-born IoT twin-tech that started the whole low-power wide-area (LPWA) movement, and forced the cellular community to come up with their own alternatives – have not been much better, necessarily, the story goes. Sigfox pumped $350 million over 10 years into its technology and network, only to go into receivership at the start of 2022 with fewer than 20 million devices under management.

The problem, said Nemish, is with the business model, and not the tech. (As an aside, a takeaway from The Things Conference last week, as from the LoRaWAN World Expo in Paris in the summer, and from any number of private discussions in between, is the IoT market is mature enough to let go of its closely-held tech differences, and acknowledge that customers don’t really care so long as it works – and so the blame switches to the business model, instead.)

Nemish blamed Sigfox’s ‘failure’ on exclusive single-market contracts and cripping licensing fees; these “killed most operator business plans”, he suggested. Of course, Sigfox lives to see another day – and, it might be noted, Taiwan-based IoT house Unabiz, its new owners, have just hosted the 0GUN Alliance of Sigfox operators in France to bash-out a new operator model, and a collaborative approach to a “unified LPWAN world”.

And LoRaWAN is not exempt in the analysis, either. In Amsterdam, Nemish held up the madly-hyped Helium model for crypto-led community network building as another failed IoT business model. Again – and of course, with a critical appraisal of a LoRaWAN network by a LoRaWAN provider – the tech is not the problem, just the way it is being offered. Because Helium, he said, with $1 billion of public community funding, has “no use” after three years.

As per the slide, parent Nova Labs has “failed to sign customers, implement SLA(s), or plan network evolution”, he suggested. The community behind it, originally bedsit enthusiasts on to a good thing, are not motivated by “IoT adoption but [by] crypto-mania”, said Nemish. Just look on eBay, where 10,000 secondhand Helium miners (gateways) are being flogged, to see how its star has fallen, he said – along with its stock, with HNT trading up 12 percent at around $5 at writing, on the back of a deal for decentralised 5G with T-Mobile in the US, but down from a high of nearly $30 a few months ago.

The article highlights some heated discussions on the presentation and slides. You can read the whole article here.

The closing slide nicely summarises that IoT deployment is a marathon, not a sprint. End users are interested in solving real-world problems. Partner to develop complete IoT solutions that can be integrated simply with any IoT platform and with clearly defined API. Also have a strong engineering team to support customer integration and early deployment.

Energy Consumption in Mobile Networks and RAN Power Saving Schemes

We just made a tutorial on this topic looking at where most of the power consumption in the mobile network occurs and some of the ways this power consumption can be reduced. 

The chart in the Tweet above (also in the presentation) clearly shows that the energy costs for operators run in many millions. Small power saving schemes can still have a big impact on the total energy reduction, thereby saving huge amounts of energy and costs.

The March issue of ZTE Communications Magazine contains some good articles looking at how to tackle the energy challenges in the network going forward. This recent article by Ericsson is also a good source of information on this topic.

Anyway, the slides and the video of the tutorial is embedded below:

Reducing 5G Device Power Consumption Using Connected-mode Discontinuous Reception (C-DRX)


Back in 2019, when we were still participating in physical event, I heard Sang-Hoon Park, ESVP, Head of Regional Network O&M Headquarter, KT talk about 'KT’s journey to large-scale 5G rollout' at Total Telecom Congress.

South Korea is blessed with three highly competitive MNOs and due to this, the government asked them to launch their 5G networks at the same time in 2018. I have also blogged about how KT is working on reducing the latency of their network here.

Anyway, as you can see in the picture above, using Connected-mode Discontinuous Reception (C-DRX), KT was able to show huge power saving in the 5G Samsung smartphone. They also made a video embedded below:

KT has some more details from their blog post back in 2019 here. Also some more details on RayCat here. Both the sites are in Korean but you can use Google translate to get more details.

What is KT battery saving technology (C-DRX)?

KT's'battery saving technology' is shortened to'Connected Mode Discontinuous Reception' and is called C-DRX. In simple terms, it is one of the technologies that reduces battery usage by periodically switching the communication function of a smartphone to a low power mode while data is connected.

In CDRX technology, the base station and the terminal share CDRX information through RRC setting and reconfiguration, so when there is no packet transmission/reception by the terminal, the terminal transmission/reception terminal can be turned off to reduce battery consumption, and the CDRX setting is optimized to reduce the user's battery consumption. It is possible to increase the available time for related applications.

In order to reduce the battery consumption of the terminal, it is a technology that controls the PDCCH monitoring activity, which is a downlink control channel related to the terminal identifier, through RRC. The base station controls the CDRX through RRC, and how the communication company optimizes and applies this was a big task. Is the first in Korea to optimize this technology and apply it to the national network.

In simple terms, the smartphone is not using communication, but it turns off the power completely and enters the standby state to reduce power consumption. When not in use, it completely turns off the power wasted in transmitting and receiving even during the standby time, thus extending the user's smartphone usage time.

As can be seen from the picture above, battery saving technology saves battery by completely turning off the communication function when there is no data or voice call. If the network does not have the battery saving technology applied, it is always connected to the communication network and waits even when not in use. Then, the battery is always connected to the communication function and the battery saving technology overcomes this part.

When Qualcomm announced their Industry’s First Mobile Platform with Integrated 5G back in 2019, the press release said:

The new integrated Snapdragon 5G mobile platform features Qualcomm® 5G PowerSave technology to enable smartphones with the battery life users expect today. Qualcomm 5G PowerSave builds on connected-mode discontinuous reception (C-DRX, a feature in 3GPP specifications) along with additional techniques from Qualcomm Technologies to enhance battery life in 5G mobile devices – making it comparable to that of Gigabit LTE devices today. Qualcomm 5G PowerSave is also supported in the Snapdragon X50 and X55 5G modems, which are expected to power the first waves of 5G mobile devices introduced this year.

The picture is from the slide deck here. See links in further reading below to learn more about this feature.
