Wireless interests made pitches for requiring 3.7 GHz licensees to make available time division duplexing synchronization with citizens broadband radio service operations in the adjacent band, in docket 18-122 replies posted Tuesday to responses to the petitions for reconsideration of the FCC C-band order. The C-band transition cost catalog is useful only if accurate, and getting additional comment won't delay the move, NCTA said, saying the Wireless Bureau should at least continue to revisit and seek occasional comment on the catalog to ensure the cost amounts stay reasonable. It said the FCC should make clear CBRS operations are entitled to interference protection and new 3.7 GHz licensees need to work with CBRS operators in good faith to prevent and mitigate that interference, including by making TDD available to CBRS operators. The Wireless ISP Association and NTCA also backed requiring flexible use licensees in the C band making TDD synchronization information available to adjacent CBRS band users. Charter said no one disputed the benefit of TDD synchronization, so requiring it would provide certainty. Intelsat said it can't be responsible for interference to earth stations post-transition if rules don't protect against flexible use operations' interference. It urged reconsidering technical specifications for telemetry, tracking and control (TT&C) filters. Recapping meetings with staff for FCC Chairman Ajit Pai and Commissioner Mike O'Rielly, NAB and content companies urged either all integrated receiver/decoder (IRD) equipment costs be allocated as a satellite cost, with satellite operators paying installation costs to MVPDs, or bifurcated, with the equipment costs a satellite operator expense and costs of installation allocated to the MVPD and in the lump sum. They said the average estimated cost of installation of an IRD is $900 when installed by the MVPD or a contractor. In a back-and-forth over Eutelsat's petition, SES filed. If carriers, which ultimately will pay moving costs, don't object to reimbursement criteria, it's hard to see what legitimate grounds those non-C-band users stand on, it said. Eutelsat said the opposition doesn't refute its core argument the move would proceed more smoothly with the FCC being absolutely clear about what are reasonable and necessary reimbursement costs. T-Mobile urged rejecting recon petitions seeking more protections for incumbent earth station users, TT&C/gateway sites and CBRS.
European regulators may not make decisions for another 10 years on the future of broadcast TV in the UHF band, speakers said Monday at conclusion of the virtual European Spectrum Management Conference. The FCC repurposed 84 MHz of UHF for wireless in a 2016-17 incentive auction. Such a swath in Europe remains hotly contested between carriers seeking low-band for 5G and broadcasters.
The FCC remains concerned about receiver standards, Wireless Bureau Chief Donald Stockdale said at the virtual European Spectrum Management Conference Wednesday. Stockdale suggested the FCC do more to address the issue. Speakers on a second panel said Europe may not follow the U.S. in allocating the entire 6 GHz band for Wi-Fi and other unlicensed use, which the FCC did in April (see 2004230059).
The citizens broadband radio service band appears to be off to a strong start, FCC Commissioner Mike O’Rielly said during a ConnectX webinar Tuesday. O’Rielly expects July 23’s priority access license auction to take place as planned, though he said that’s a decision to be made by Chairman Ajit Pai. Other speakers said CBRS will get wide use.
The citizens broadband radio service auction, scheduled to start July 23, will likely be active, with bids from some that don’t normally play in FCC auctions, Wells Fargo’s Jennifer Fritzsche told investors. “Cables' interest here will be significant,” she predicted Tuesday: “The more spectrum cable [companies] actually own, the more traffic they can shift AWAY from the MVNO [mobile virtual network operator] network partner they used to carry … non-Wi-Fi traffic.” She noted Comcast and Charter were among potential bidders on the list released by the FCC (see 2006080048).
All signs are the citizens broadband radio service auction will start July 23 as planned, especially with FCC Chairman Ajit Pai concerned about a December C-band auction, industry and FCC officials said in recent interviews. The auction of priority access licenses was delayed once from June 25, because of COVID-19 concerns (see 2003250052). The agency announced Monday that 348 companies or individuals filed short forms to participate; 106 were deemed complete while others require additional work.
Wireless and satellite interests cited concerns about the FCC C-band order, in docket 18-122 petitions for reconsideration posted Wednesday. Change the technical specifications of telemetry, tracking and command filters because they aren't feasible, or give Intelsat's two remote TT&C/gateway sites protected status to use the entire band, the company petitioned. It said out-of-band protection requirements won't adequately protect all earth stations from post-transition interference and need revision, or at least make clear that as long as Intelsat has done everything it can, it won't be held responsible for terrestrial operations' interference. It urged moving of the December 2021 TT&C/gateway site consolidation deadline to 2023 because an 18-month consolidation window is "simply is not achievable given the many time- and resource-intensive activities." Speaking with FCC staffers, Intelsat officials cited filter and TT&C site concerns and said reimbursements shouldn't be limited to satellites operating solely with a C-band payload, since its satellites are typically configured with multiple spectrum payloads and it was going to seek reimbursement for only the C-band payload costs. The company voiced concerns about cable operators being able to select the compression equipment to be installed at their earth stations, when it should be tied to the satellite transponder. Also posted was Intelsat's accelerated relocation election the company announced Tuesday (see 2005260037). The International Telecommunications Satellite Organization's recon petition cited aspects of the C-band order that could hurt international satellite services by limiting international gateway services in the lower portion of the band to four TT&C sites, and only on a secondary basis. It said design and placement of replacement Intelsat satellites could hurt international satellite services customers outside the U.S. C-band operator Eutelsat had petitioned for recon. Charter asked the FCC to tweak the order to require C band flexible use licensees to make TDD synchronization available to citizens broadband radio service (see 2005220042). “Without such synchronization, C-Band base stations will interfere with, and significantly impede, the ability of CBRS base stations to communicate with CBRS user equipment operating in both the Priority Access License and General Authorized Access spectrum blocks,” Charter said. Aviation interests asked to change the order to protect radio altimeters using 3700-3980 MHz (see 2002200030). "‘No action’ regarding the protection of radio altimeters and seemingly requiring the aviation community to ‘protect thyself’ from harmful interference was not supported by the evidence and sharply contrasts with other actions taken in this very proceeding,” the groups said. The Aerospace Industries Association, Airbus, Aviation Spectrum Resources, Aerospace Vehicle Systems Institute, Air Line Pilots Association and Garmin were among signers.
Charter Communications said a new technical analysis shows C-band operations are an interference threat to licensed and unlicensed use of the nearby citizens broadband radio service band. “The level of interference that will be experienced by CBRS could result in degradation and devaluation of this valuable mid-band spectrum, undermining the competition and innovation that will only continue to grow and flourish in this spectrum band,” Charter said in calls with FCC staff. But Charter said the FCC could solve problems by requiring C-band licensees to make time division duplexing (TDD) available to CBRS licensees and users upon request: “Mandating TDD synchronization is critical because there is no assurance that larger carriers will voluntarily work cooperatively with new entrants and smaller carriers to address this problem and resolve interference for all carriers.” Charter spoke with staff from the Wireless Bureau and Office of Engineering and Technology and aides to Commissioners Mike O’Rielly and Geoffrey Starks, said a filing posted Friday in docket 18-122.
With the FCC auction of priority access licenses (PAL) to start in July, and companies using the general authorized access (GAA) tier, speakers on a FierceWireless webinar Thursday saw growing interest in the citizens broadband radio service band. Speakers from three of the five FCC-authorized spectrum access system (SAS) administrators, CommScope, Federated Wireless and Google, said they are demonstrating CBRS will live up to the hype.
Ultra-high band spectrum remains a “wild, wonderful and challenging” world, said Ted Rappaport, director-NYU Wireless at New York University School of Engineering, during a National Science Foundation webinar Wednesday. The FCC tapped Rappaport to speak on the importance of spectrum above 95 GHz before a vote last year approving the spectrum horizons order (see 1903150054). Some are looking to spectrum as high as 700 GHz, he said. Commissioners will consider an NPRM on the 70, 80 and 90 GHz bands at their June 9 meeting (see 2005190058).
