5g能效：绿色是新的黑色（续集）

November 2023 The GSMA is a global organisation unifying the mobileecosystem to discover, develop and deliver innovationfoundational to positive business environments andsocietal change. Our vision is to unlock the full power ofconnectivity so that people, industry and society thrive.Representing mobile operators and organisations acrossthe mobile ecosystem and adjacent industries, the GSMAdelivers for its members across three broad pillars: GSMA Intelligence is the definitive source of globalmobile operator data, analysis and forecasts, andpublisher of authoritative industry reports and research.Our data covers every operator group, network andMVNO in every country worldwide – from Afghanistan to GSMA Intelligence is relied on by leading operators,vendors, regulators, financial institutions and third-partyindustry players, to support strategic decision-making and Our team of analysts and experts produce regularthought-leading research reports across a range of We invite you to find out more at gsma.com Follow the GSMA: @GSMA www.gsmaintelligence.com info@gsmaintelligence.com @GSMAi Authors Emanuel Kolta, Lead Analyst, Network Sustainability andInnovation Tim Hatt, Head of Research and Consulting This report was authored by GSMA Intelligence withsupport from ZTE. © GSMA Intelligence 2023 Contents Executive summary...........................................................................................................4 1.1 Telecoms among the global leaders on commitments...................................................51.2 Measuring progress so far.............................................................................................6 2.1 Energy use across the network......................................................................................82.2 Energy at the industry level............................................................................................9 3.

While mobile networksprovidenear-ubiquitous access toconnectivity, convenience and entertainment, greater use of smartphones for video and other In November 2020, GSMA Intelligence published the flagship report,5G energy efficiencies: greenis the new black. Much has changed since then. Given the growing strategic importance of thetopicforthe telecoms industry, this research revisits the 2020 report’s main questions and This edition examines how networks consume energy and how site, RAN and network-wideinnovations can help boost efficiency. It also delves into initiatives network operators andtechnology vendors have rolled outover the past three years targeting energy-efficiency gains, netzero, and climate KPIs and reporting. The research establishes the context and rationale for The energy-efficient network of the not-too-distant future While traditional network infrastructure includesextensive air-conditioning units as well as shelters •highly integrated radios and antennas with heat sinks •software for control and adjustment, with hardware more commoditised •individual sites and whole networks controlled with AI-driven network managementsoftware. This collects real-time information on network load, capacity, weather and The changeinnetwork strategy means energy efficiency is now a core objective–just as securityand performance are. This report aims to help understand the factors helping or hindering that 1.The imperative to reduce emissions 1.1Telecoms amongtheglobal leadersoncommitments The imperative to reduce CO2 emissions has environmental and business rationales. GSMAIntelligence has written extensively on both, with the latter a focus in theGreen is Good for Environmental commitments are anchored in the Paris Accord of 2015. The 1.5°C trajectory has anet-zero target date of 2050, implying 50% reductions in each of the preceding three decades(50% CO2 reductions on 2020 levels by 2030 and so forth). Politicalefforts to embed climateobjectives as part of national development and economic transformations have been highlighted atthe various global climate conferences (COPs) held since 2015. Government action on the climate In many cases, the private sector has been a leading force in stepping up to net-zero timelines,aspart of corporate transformation to a sustainable operating model. The telecoms industry is amongthe global leaders in this respect. I
