Industry companies and groups disagreed sharply on the best way for the FCC to open the 12.7 GHz band for other users, and whether it should be offered for exclusive-use licenses or be the next big sharing band. Band incumbents urged caution. Comments were due Monday and posted Tuesday in docket 22-352. The FCC approved a notice of inquiry in October on what others call the 13 GHz band (see 2210270046).
CBRS
The Citizens Broadband Radio Service (CBRS) is designated unlicensed spectrum in the 3.5 GHz band created by the FCC as part of an effort to allow for shared federal and non-federal use of the band.
CTIA clarified its stance on the citizens broadband radio service band, in a letter Monday to FCC Chairwoman Jessica Rosenworcel and NTIA Administrator Alan Davidson, noting the group supports CBRS in general, though it’s “premature to expand the experimental CBRS sharing mechanism.” A CTIA study last month argued the CBRS model isn’t a substitute for exclusive-use licensing (see 2211140062). “Some parties have called on the Administration and the FCC to focus future spectrum access on the experimental CBRS sharing framework used in the 3.5 GHz band,” the letter said: “To be clear, the wireless industry is not, as some CBRS proponents claim, arguing that all spectrum must be exclusive-use licensed spectrum. We support innovative uses of spectrum where it is appropriate and makes sense given technical and operational constraints.” CTIA said it “filled a void to act as the certifying body for CBRS devices to help with initial commercialization, and was prepared to act as a sharing database administrator because of an initial lack of interest and options,” the group said. “At the same time, we believe future spectrum policy in the United States should not default to complex spectrum sharing regimes, and the weight of the evidence continues to show that smart domestic spectrum policy should be built upon robust access to exclusive-use, licensed spectrum particularly given the significant deficit today.”
FCC and NTIA officials defended the citizens broadband radio service band as potentially offering a model for future sharing, during an FCBA spectrum pipeline forum Monday. Last week, CTIA questioned whether CBRS, often cited as the potential sharing model of the future, is a suitable replacement for exclusive, licensed spectrum (see 2211140062). CBRS advocates have fired back.
Federated Wireless and Charter Communications representatives highlighted the benefits of spectrum sharing and the model offered by the citizens broadband radio service band, in a meeting with FCC Commissioner Nathan Simington. The CBRS model “facilitates the growth of mobile competition and has enabled new entrants into the market, many of whom are using the band to develop their own private networks for uses such as industrial automation, artificial intelligence, and predictive maintenance,” said a filing posted Thursday in docket 17-258. CBRS is used “in environments ranging from warehouses, ports, factories, airports, and office buildings, in rural as well as densely populated areas, supporting supply chain efficiency."
A top DOD spectrum official defended the citizens broadband radio service band, writing in a new posting released as CTIA questioned whether CBRS is really the sharing model of the future (see 2211140062). “Dubbed by some as ‘the Innovation Band,’ CBRS offers the some of the features of traditional wireless and Wi-Fi, but with lower fixed costs, higher quality, greater efficiency, and increased security,” said Vernita Harris, DOD director-spectrum policy and programs, on LinkedIn Monday. “With CBRS, the U.S. military can continue to use critical radars systems while commercial users have leveraged CBRS in a variety of sectors, ranging from real estate to health care to utilities,” she said. Harris said CBRS shows “unprecedented coordination between federal users, regulators and industry” and benefited from “groundbreaking” automation. “More work lies ahead, but the results of CBRS so far are promising, and those involved in its success so far should be proud,” she said: “The DOD, other federal spectrum users, and industry continue to look for new use cases along with ways to improve the existing CBRS system. Trust across government and industry underpins the development of holistic spectrum solutions for EVERYONE’s benefit.”
A new study by CTIA and Recon Analytics questions whether citizens broadband radio service spectrum, often cited as the potential sharing model of the future, is a suitable replacement for exclusive, licensed spectrum. Meanwhile, the Biden administration is moving on release of a national spectrum strategy (see 2209260048). Carriers already said they hope the strategy will lay out bands that can be cleared for licensed use. Wi-Fi advocates fired back.
Ericsson said Monday it hit a data rate of 1 Gbps in a 5G stand-alone network field trial, setting a data speed record with citizens broadband radio service spectrum in an indoor environment. “Conducted at Ericsson’s North American headquarters in Plano, Texas, and coordinated by the OnGo Alliance, this trial was supported by Ericsson’s 5G Distributed Innovation Network and harnessed Radio 4408 for outdoor CBRS connectivity and the Radio Dot 4459 for indoor CBRS connectivity,” Ericsson said: “In addition to record-setting speed, the trial also resulted in seamless outdoor-to-indoor connectivity transitions, paving the way for benefits to consumers and enterprises alike.”
Geostationary orbit (GEO) satellites are limited in their ability to connect people around the world, but low earth orbit (LEO) satellites offer much more promise, said Ruth Pritchard-Kelly, OneWeb senior adviser-satellite regulatory affairs and sustainable space policy, Thursday at IEEE’s virtual Connecting the Unconnected Summit. Other speakers said it’s difficult to even count how many people remain without internet service in many parts of the world.
Charter Communications is dealing with higher-than-expected costs for its Rural Deployment Opportunity Fund buildout but also is having more success than expected in penetration and number of passings being developed off RDOF projects, CEO Tom Rutledge told analysts Friday as the company announced Q3 results.
Etheric asked California Public Utilities Commissioner Darcie Houck to put a hold on a proposed decision, scheduled for vote Oct. 20, that would deny the company designation as an eligible telecom carrier (ETC). Etheric, which needs ETC status to get $248 million in Rural Digital Opportunity Fund (RDOF) support, met virtually with a Houck aide Oct. 7, Etheric reported Wednesday. The CPUC draft includes “high-level conclusions” with no “explanation,” Etheric complained. Etheric filed its application more than two years ago, in January 2020, but had only one meeting with staff, Oct. 5, after the draft’s release, it noted. Concerns expressed about the company’s “financial ability to carry out the RDOF project were based on a misunderstanding of a letter submitted by” venture capital firm Summit Partners, Etheric said. The letter “included a standard disclaimer in a footnote meant to indicate that due to the amount of time that has passed since its initial underwriting of the project, it would need to reconfirm its underwriting and finalize credit documentation at the time Etheric receives ETC designation and the FCC publishes a public notice with final approval for the RDOF award.” To clarify, Etheric attached a letter from Summit. The CPUC proposal incorrectly found Etheric’s cost estimates for the RDOF project are too low, possibly “due to a misunderstanding about the FCC’s reserve price for the Census Blocks won by Etheric,” the company said. The FCC’s $541 million reserve price was based on all-fiber design, but Etheric calculated $248 million would cover a hybrid network mixing fiber and fixed wireless, it said. Etheric made sure it can scale its existing network and “any staff concerns about scalability should be fully addressed by the substantial financial resources at its disposal,” it said. Responding to concerns about fixed wireless performance in mountainous and dense foliage areas, Etheric said 75% “of its RDOF locations have direct line of sight between the network and customer location.” Of remaining areas, 11% will get fiber, while 14% will use citizens broadband radio service (CBRS) “UNII mid-band Tarana Radio Systems to ensure good signal levels for the light foliage conditions at those locations.”
