Samsung Electronics America asked the FCC to move quickly on its request to market and operate a 5G base station radio that works across citizens broadband radio service and C-band spectrum (see [Ref:2303100019). Charter Communications was the lone commenter to urge caution. As with initial comments, there were two replies, posted Wednesday in docket 23-93. “Both commenters in the record -- one operator and one manufacturer -- support grant of a waiver,” Samsung said. “Defer acting on Samsung’s petition until interested stakeholders have had a reasonable opportunity to review and comment on the results of Samsung’s tests on whether and how its novel dual-band transmitter satisfies the CBRS out-of-band emissions and in-band emissions levels in each mode in which the Samsung base station can operate,” Charter said: If the FCC decides to approve the radio now it should “condition any grant on Samsung immediately ceasing operations if the base station causes harmful interference to CBRS operations.”
A waiver request by Samsung Electronics America for a 5G base station radio that works across citizens broadband radio service and C-band spectrum (see 2303100019) got some support at the FCC, with no one filing in opposition. Comments were posted Tuesday in docket 23-93. The FCC recently approved a similar waiver for a multiband waiver for Ericsson, and Ericsson recently sought a second waiver that parallels the Samsung request (see 2303170044). The waiver addresses out-of-band emissions limits in the CBRS band. Verizon, which noted it has significant operations in both bands, said a single radio is easier to deploy than two. “The smaller size of the multiband device, compared to two separate devices, will ease the regulatory siting process itself, enabling faster deployments,” Verizon said. A single radio will also increase energy efficiency by as much as 45% compared with two stand-alone units, the carrier said. “Multiband 5G radios incorporate multiple spectrum bands in a single radio, reducing energy consumption and resulting in a much smaller cell site footprint, thereby facilitating faster zoning review and easier siting,” Ericsson said. The Samsung petition and its follow-up petition demonstrate that the waiver of the CBRS OOBE limits “will not negatively affect operations” in either band, the company said: “Strict application of the OOBE limits at issue would not serve the public interest. The alternative would be to manufacture and install two separate radios, which would increase the time, costs, and energy consumption of deploying 5G networks.”
The “jury’s still out” on whether the FCC’s 3.45 GHz auction was a success, said John Hunter, T-Mobile senior director-technology and engineering policy, during an FCBA wireless lunch Wednesday. Speakers welcomed the administration’s early steps on a national spectrum strategy (see 2303200044).
Ericsson petitioned the FCC for a waiver that would allow manufacturing and marketing of “more energy efficient, climate friendly, smaller and easier to deploy multiband base station radios” operating on the citizens broadband radio service band and C band. Ericsson, which already received one waiver for a multiband radio, said its request parallels that of Samsung Electronics America's, on which the FCC is seeking comment (see 2303100019). “Like Ericsson, Samsung recognizes the significant benefits of multiband base station radios,” said a filing posted Friday: “Ericsson supports grant of the Samsung waiver petition and its underlying rationale and urges swift Commission action there.”
NTIA is moving forward on its long-awaited national spectrum strategy, releasing a request for comments Wednesday that poses more than 60 questions on what that strategy should include. NTIA also scheduled two “listening sessions.” Comment deadlines are to come in a Federal Register notice, to be filed in NTIA-2023-0003.
CommScope notified the FCC it’s suspending operations as a spectrum access system manager in the citizens broadband radio service band, effective April 1. “We will no longer be providing SAS services nor accepting CBSD [CBRS device] registrations,” said a notice posted Monday in docket 15-319: “In addition, CommScope will securely transfer all currently registered CBSDs to other Commission-approved SAS administrators by April 1.” The company will retain records not pertaining to federal incumbents for five years, the notice said. CommScope was one of the original SAS providers, along with Google and Federated Wireless. CTIA noted in a report last year that CommScope had effectively abandoned the market earlier in the year. “While Commscope remained silent about its reasons one can reasonably surmise it was due to a lack of expected demand,” the report said: “Companies do not often abandon profitable lines of business.”
The FCC Wireless Bureau and Office of Engineering and Technology sought comment Friday on Samsung Electronics America's request in August for a waiver allowing it to offer a radio that works across citizens broadband radio service and C-band spectrum. Comments are due March 27, replies April 4, in docket 23-93. “At the time the C-Band Order was adopted, the CBRS auction had not even commenced,” Samsung said in a petition seeking the waiver: “No one knew who would win licenses in CBRS, let alone in the 3.7 GHz auction which would not end for another year. Carriers were still determining what their mid-band strategies would be and how they could use one or both bands. The world has evolved significantly since then. Grant of Samsung’s waiver request is appropriate now to ensure that carriers have the equipment they need to rapidly deliver on the promise of their 5G networks.” The FCC recently approved a similar waiver for a multiband waiver for Ericsson, which had broad support (see 2208240045).
A Friday House Communications Subcommittee hearing intended to jump-start negotiations on a comprehensive spectrum legislative package touched on some of those policy issues, but subpanel members used it as a bully pulpit to blast the Senate for failing to prevent the FCC’s frequency auction authority from expiring Thursday, as expected (see 2303090074). The House gaveled out Friday for a recess scheduled to end March 22. Senate leaders and Sen. Mike Rounds, R-S.D., who disagreed about dueling bills to renew the commission’s mandate (see 2303080081), expect to return to negotiations this week.
Federated Wireless representatives spoke with staff from the FCC Public Safety Bureau on “the successes” of the citizens broadband radio service band’s spectrum sharing model and the implications for 4.9 GHz, the topic of a recent order and Further NPRM (see 2301180062). Federated discussed “the similarities between the proposed 4.9 GHz Band Manager responsibilities and the activities Federated Wireless performs in our role as a CBRS Spectrum Access System administrator,” said a Wednesday filing in docket 07-100. Similarities include “frequency coordination and protection of incumbent operations; design and implementation of private 5G wireless networks for diverse commercial and public sector use cases; and management of a streamlined secondary market for CBRS Priority Access License leases,” Federated said. The CBRS band has “strong momentum” with more than 312,000 base stations deployed nationwide “in only 3 years,” the company said.
While the lineup of cable operators providing mobile service grows, with others likely to follow, most will rely on mobile virtual network operators and their own Wi-Fi networks to provide the service rather than become more active in acquiring spectrum for their own wireless networks, wireless and cable experts tell us.
