Mobile Evolution in 6 GHzThe impact of spectrum assignment September 2024 The GSMA is a global organisation unifyingthe mobile ecosystem to discover, developand deliver innovation foundational topositive business environments and societalchange. Our vision is to unlock the full powerof connectivity so that people, industry andsociety thrive. Representing mobile operatorsand organisations across the mobile ecosystemand adjacent industries, the GSMA delivers GSMA Intelligence is the definitive sourceof global mobile operator data, analysis andforecasts, and publisher of authoritativeindustry reports and research. Our data coversevery operator group, network and MVNO in GSMA Intelligence is relied on by leadingoperators, vendors, regulators, financialinstitutions and third-party industry players, tosupport strategic decision-making and long- Our team of analysts and experts produceregular thought-leading research reports across We invite you to find out more atgsma.com Follow the GSMA on Twitter/X:@GSMA www.gsmaintelligence.cominfo@gsmaintelligence.com Authors: Kalvin Bahia, Senior Director of Economics,GSMA Intelligence Contents Executive summary 1.Introduction10 2.Evidence on mobile and Wi-Fi utilisation 3.Economic assessment of policy options in theupper 6 GHz band 4.Economic assessment: results and key findings Appendix 1: Methodology Executive summary New evidence on traffic growth, networkutilisation and efficiency of spectrum use Considerations on the optimal approach formanaging spectrum in the 5.925–7.125 GHzfrequency range are at the forefront of globaldebate. Following the conclusion of the WorldRadiocommunication Conference 2023 (WRC-23), countries representing 60% of the globalpopulation sought inclusion in the identification of —Most mobile use is indoors and largelydelivered over mid-band spectrum.In thecase of indoor 5G, the majority of traffic isdelivered in the 3.5 GHz frequency range, whichprovides high-performance indoor coverage,with data rates up to 16× faster than with 5G Debate on the use of the 6 GHz band forms partof a wider discussion on the future of connectivity.The digital needs of industry, businesses andconsumers have a clear impact on spectrummanagement considerations, including the useof licensed and unlicensed spectrum, and macro-and small-cell public mobile networks. To assist —There is scope to improve the efficiency ofunlicensed Wi-Fi spectrum use.In the cities1 considered in this study during Q1 2024, datagathered by Ookla shows that between 22%and 78% of Wi-Fi usage was on legacy Wi-Fi 4technology. The lower 6 GHz band was hardlyutilised for Wi-Fi 6. Studies that have assessedWi-Fi spectrum needs indicate a spectralefficiency range from 1 to 9 bps/Hz.2The lowerend of this range represents sub-optimal use Key findings —Mobile and fixed operators will need tomanage significant traffic growth on theirnetworks over the next decade.Global mobiletraffic growth in 2023 was the largest of anyyear to date. The 2023 increase alone wasgreater than the absolute traffic level in 2018. —5G is expected to deliver spectral efficiencies of around 6 bps/Hz, which is seven timesmore efficient than 3G,3as spectrum licencesmean operators face a pricing signal to utilisespectrum efficiently. In addition to improving Policy options for the upper 6 GHz band Leveraging this new evidence, this study analysesthe economic benefits of three different policy efficient utilisation of spectrum, which followsbest-practice decision making, the analysis showsthat unlicensed assignments in the 2.4, 5 and —licensed mobile use (Scenario 1) —With regard to shared use, the results showthat restricting the power levels mobile basestations can emit in the upper 6 GHz band willsignificantly reduce the additional capacity theycan provide. As a result, the economic benefitsare lower than having a fully licensed macro- —unlicensed RLAN use (Scenario 2) —enabling shared use by reducing the powerlevels of mobile deployments (Scenario 3). Governments and regulators are invited to considerthis analysis, with the report presenting results for Key findings —The greatest economic benefit in all countries isScenario 1, where the upper 6 GHz is assigned —For regulators wishing to pursue a shared useapproach to the upper 6 GHz band, it is vital toincentivise efficient spectrum use by ensuringany requirements and additional costs to sharespectrum are not solely imposed on mobileoperators, but also place responsibility on Wi-Fiproviders. If the technical conditions for sharing —This scenario drives the greatest benefitbecause mobile is much more likely thanWi-Fi to be capacity constrained in each countryover the period to 2035. This means additionalspectrum in the upper 6 GHz band will drive options for the upper 6 GHz band; it can serve as aframework to inform decision-making. 1.Introduction 1.1 The need for an updated assessment To assist policymakers in assessing their options fort
