In a brand new report, ATIS’ NextG Alliance appears to be like at anticipated 6G spectrum wants primarily based on anticipated KPIs
With the telecom business, and governments around the globe, already looking forward to future 6G techniques and the spectrum that they could make the most of, how ought to they be enthusiastic about the quantity of spectrum that can be wanted for 6G? In any case, the know-how hasn’t but been standardized, use circumstances are merely best-guesses at this level and “as a lot as we will get, particularly within the midband vary” leaves one thing to be desired as a foundation for spectrum coverage and planning.
The Alliance for Telecommunications Business Options (ATIS)’s NextG Alliance, as a part of its exploration of the roadmap to 6G, took a stab at assessing future 6G spectrum wants in a new white paper. The group acknowledges that there are a lot of unknowns at this level, however notes that basically, “The evolution of business cellular broadband over its generations is characterised by a continued enhance within the effectivity in the usage of spectrum
and within the quantity of spectrum used to help novel and numerous wi-fi functions.” As in, the business is utilizing an increasing number of spectrum with every G, but in addition doing so extra effectively, and each of these issues are anticipated to proceed in 6G.
“Spectrum is the lifeblood for all business cellular broadband,” mentioned Andrew Thiessen of MITRE, who’s the chair of the Subsequent G Alliance Spectrum Working Group. “Absent out there spectrum, the flexibility for nations to proceed to maneuver in the direction of ubiquitous connectivity is stymied. This doc affords a complete first take at what spectrum can be wanted as 6G improvement begins in earnest.”
The white paper focuses totally on North American contexts and desires, and appears at potential spectrum wants for 6G when it comes to key efficiency indicators and certain velocity necessities for quite a lot of use circumstances, from very low-date-rate asset administration makes use of and environmental sensors, to mid-speed use circumstances resembling clever transportation and UAVs (keep in mind, it’s assessing primarily based on velocity KPIs, not latency), to extraordinarily demanding use circumstances like prolonged actuality, autonomous techniques and industrial robotics.
The paper appears to be like at simulating demand, primarily based on a broad vary of velocity classes anticipated to be wanted for the assorted use circumstances, in candidate bands at 3.1-3.45 GHz, 7.125-8.5 GHz and 12.7-13.25 GHz—bands which can be broadly thought of midband and higher midband. Three cell sizes had been simulated: 1,732 meters (or a few mile), 500 meters and 250 meters, with consideration of various city and rural deployment eventualities together with public macro cells, and public or personal microcell deployments.
What did ATIS discover? Broadly, that rural macro-cell deployments to help the broad anticipated span of 6G use circumstances would require the least quantity of spectrum, and concrete macro-cells would require essentially the most, with city micro-cell environments falling someplace within the center. Whereas it warned that its numbers shouldn’t be taken as “sensible wants of any 6G deployment” however as an alternative replicate traits of KPIs for numerous functions, it did put some numbers on the market as examples of spectrum wants per frequency band to attain these KPIS: An estimated 1,070 megahertz within the decrease 3 GHz band; barely much less, 1,019 megahertz at 7.125-8.5 GHz, and greater than 2,100 megahertz to attain the objective KPIs at 12.7-13.25 GHz.

“Proactively understanding subsequent G spectrum wants and planning for them is crucial to U.S. management in important and rising applied sciences,” mentioned Subsequent G Alliance Managing Director David Younger. “Selections about the usage of spectrum depend upon a number of elements and require time to be carried out. This paper achieves an understanding of 6G spectrum wants in order that these wants are thought of within the improvement of data-driven insurance policies, regulatory selections, and technical options.”
