CTIA calls CBRS sharing ‘unproven,’ ‘ struggling’


New report attracts sharp criticism from different business teams, firms supporting CBRS

Amid ongoing Capitol Hill conversations about new spectrum allocations, a CTIA report assaults the efficacy of spectrum sharing and argues that the three-tiered Residents Broadband Radio Service is struggling in comparison with exclusive-use preparations.

CTIA, which represents cell community operators’ coverage pursuits, launched a report by Recon Analytics this week that claims that CBRS has “low utilization, low market demand, and a dearth of revolutionary use circumstances,” as Roger Entner, founder and lead analyst of Recon Analytics, put it.

“Throughout each dimension and each metric – effectivity, utilization, demand – full energy, unique use, licensed business spectrum has succeeded the place CBRS has struggled thus far,” the report says, occurring so as to add: “The inescapable conclusion is that CBRS spectrum can be extra broadly utilized, at larger ranges of effectivity, and ship extra worth to federal incumbents, business customers and the American shopper had it been made accessible for excusive [sic], licensed use.”

“A assessment of right now’s CBRS market exhibits that CBRS doesn’t stay as much as the hype as the inspiration of innovation and shouldn’t be a mannequin for future spectrum coverage,” stated Entner in an announcement. “Given the extremely efficient, confirmed observe file of exclusive-use licensed spectrum, want for extra knowledge on CBRS’ efficiency, and the truth that all accessible knowledge factors to CBRS underperforming expectations, policymakers ought to chorus from utilizing CBRS sharing as a mannequin for bands sooner or later.”

“Licensed spectrum is the platform of the 5G financial system that’s remodeling the way in which we stay and work,” stated Meredith Attwell Baker, president and CEO of CTIA. “Information use is up, costs are down, and we’re already seeing improvements from driverless vehicles to AR/VR training – all due to exclusive-use, licensed spectrum. We want policymakers to concentrate on making a pipeline of extra licensed spectrum to construct on this basis and safe America’s innovation management, and never export a nonetheless unproven experiment to extra bands.”

Nonetheless, organizations and corporations which are a part of the CBRS ecosystem responded by saying that the report offers a deceptive timeline on CBRS and depends on outdated utilization knowledge from a yr in the past.

“The research … about CBRS makes use of cherry-picked knowledge and overlooks strong success throughout many alternative industries,” stated business group WifiForward in an announcement. Whereas the CTIA report emphasizes that the CBRS idea was created a decade in the past and argues that anticipated advantages haven’t materialized in that point, CBRS advocates level out that full business use of the band has solely been allowed since early 2020 and that Precedence Entry Licenses weren’t auctioned till late 2020, with the primary PALs issued round 18 months in the past. “CBRS utilization and deployments are shifting far sooner than any of the normal mobile suppliers’ deployments,” WifiForward added.

Kurt Schaubach, CTO of Federated Wi-fi, instructed RCR Wi-fi Information that the CTIA report depends on “cherry-picked knowledge in addition to previous and defective measurements, whereas conveniently side-stepping the proof that demonstrates the large business success of the CBRS band. In lower than three years, greater than 285,000 CBRS units have been deployed nationwide, and there are a file variety of customers who’ve adopted the CBRS spectrum, together with the 228 winners of the greater than 20,000 Precedence Entry Licenses and a whole lot extra Basic Approved Entry customers. It’s seen sooner, extra widespread deployment by a wider and extra numerous vary of customers than maybe some other spectrum band in historical past when it comes to the business wi-fi business.”

These spats over spectrum technique aren’t occurring in a vacuum; U.S. policymakers are within the midst of making an attempt to place collectively a brand new spectrum pipeline, with a number of payments reportedly within the works. Current public conversations round nationwide spectrum use have targeted on sharing as a viable path ahead as a result of it’s getting an increasing number of troublesome and costly to clear airwaves for unique use, notably federal army customers. Particularly, federal regulators are making ready to open the three.1-3.45 GHz band to be used, however the Division of Protection has been adamant that the band should be shared. Moreover, the Federal Communications Fee is contemplating regulation of receiver efficiency, not simply transmitters, so as to improve environment friendly spectrum use and keep away from the kind of interference points which have cropped up within the C-Band and in Ligado Networks’ proposed community plans.

Nonetheless, it’s additionally truthful to say that CBRS hasn’t essentially lived as much as the momentum that was initially anticipated, both. In January of this yr, Dell’Oro Group revised downward its expectations for the CBRS tools market, noting that Mounted Wi-fi Entry and cell broadband are driving CBRS use at present that that the enterprise/personal community share of CBRS RAN {hardware} is predicted to enhance in direction of 2026. The CBRS market remains to be anticipated to develop, simply not fairly as shortly as Dell’Oro had beforehand anticipated.

“CBRS adoption continues to maneuver in the precise route, nevertheless adoption is monitoring considerably beneath expectations, pushed primarily by diverging developments between fastened wi-fi entry (FWA) and non-FWA together with private and non-private LTE/5G NR,” stated Dell’Oro on the time. As well as, one of many operators of the elemental methods underpinning CBRS — the Spectrum Entry System — opted out of the SAS enterprise totally. CommScope stopped providing SAS providers in Could of this yr, though it nonetheless helps the CBRS Environmental Sensing Functionality (ESC) community that it runs with Google.

For his half, Schaubach says that CBRS has gained substantial momentum previously yr in each machine help and utilization. This wouldn’t be mirrored within the utilization calculations that had been made within the fall of 2021, when Teleworld Options was engaged by CTIA to exit and search for lively CBRS websites and utilization of the band; that testing resulted in a conclusion that on the time, “CBRS adoption in [multiple major] cities was low, with probably the most intensive use using lower than 5% of the spectrum city-wide.”

“Whereas CTIA had been crucial of CBRS since earlier than the FCC devised its sharing framework, the long run should embody spectrum-sharing fashions similar to that in CBRS that fastidiously stability authorities, business and shopper pursuits whereas optimizing the environment friendly use of spectrum,” stated the Colleges, Well being & Libraries Broadband (SHLB) Coalition in an announcement responding to the report. “Spectrum doesn’t develop on bushes and an unique licensed-only mannequin, which CTIA appears to want, merely won’t work for our wi-fi future.”
