It's difficult to gauge how the citizens broadband radio service launch has gone so far. In September, the FCC, in docket 15-319 cleared Amdocs, CommScope, Federated Wireless, Google and Sony to start initial commercial deployment (ICD) in the 3.5 GHz band, but the companies aren’t required to publicly report numbers. CBRS Alliance President Dave Wright of CommScope told us initial numbers are proprietary, but CBRS is moving forward as expected with full-scale launch imminent. “I continue to be extremely excited,” Wright said.
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.
Federated Wireless demonstrated a fully functional automated frequency coordinator (AFC) prototype for unlicensed services in the citizens broadband radio service band "while ensuring protection of existing services,” said Chief Technology Officer Kurt Schaubach and others in FCC meetings. An AFC can “enable new unlicensed services in the 6 GHz band as quickly as possible.” Federated discussed “potential coexistence issues at the C-Band/CBRS band edge, and the opportunity to leverage automated spectrum access tools to accelerate deployment of new terrestrial broadband services in the C-Band,” said a filing in docket 17-258, posted Friday. Federated met aides to Commissioners Mike O’Rielly, Brendan Carr and Jessica Rosenworcel and Wireless Bureau and the Office of Engineering and Technology staff, it reported. "Industry has coalesced around the need for an AFC for a wide variety of use cases.”
Wells Fargo’s Jennifer Fritzsche sees industry enthusiasm about the citizens broadband radio service, after the firm held a conference on the topic Tuesday. “Enthusiasm for the spectrum and its multifaceted use cases was shared by many participants representing different layers of the ecosystem,” the analyst told investors Wednesday. “We believe we are in the early innings in learning how CBRS spectrum and shared use deployment model will revolutionize wireless network deployments in the future. As one of the few mid-band spectrum [bands] now available for commercial use, CBRS has garnered the attention of service providers (i.e.: wireless and cable) but also new players like technology companies and enterprises for their own specific use cases.”
Telecom sector supply chain security and spectrum legislation drew enthusiastic support from House Communications Subcommittee members and witnesses during a Friday hearing, as expected (see 1909260056). They gave no clear guidance during on how they want to proceed on the seven measures the panel examined. Lawmakers focused much of their attention on the Secure and Trusted Communications Networks Act (HR-4459) and the Studying How to Harness Airwave Resources Efficiently Act (HR-4462), though they also showed interest in other measures.
PROVIDENCE, R.I. -- Competitive Carriers Association members were asked by the federal government to participate in discussions on supply chain security, carrier officials said Tuesday at CCA’s annual meeting. At the opening breakfast, big issues were 5G and what it will mean to competitive carriers. Huawei was at CCA and had a technical presentation on cybersecurity.
Huawei had “limited involvement” in the Wireless Innovation Forum Spectrum Sharing Committee's work developing the spectrum access system (SAS) and environmental sensing capability (ESC) technologies for sharing the 3.5 GHz citizens broadband radio service band, FCC Chairman Ajit Pai told seven senators in letters posted Thursday. Sens. Marsha Blackburn, R-Tenn., Richard Blumenthal, D-Conn., and five others wrote Pai and then-acting Defense Secretary Patrick Shanahan in June about their concerns (see 1906060015). The company is under scrutiny from lawmakers worried it could affect security of 5G technology (see 1905230066). Blackburn and others eye legislation to prevent President Donald Trump's administration from lifting Commerce Department Bureau of Industry and Security restrictions on Huawei (see 1907220053). The company's involvement in the WinnForum work has effectively ceased because “its membership was suspended on May 21,” Pai wrote. “I have also been informed that Huawei has not had access to any materials regarding military operations, including those of the Navy, beyond what has been made publicly available.” The WinnForum aims “to establish and maintain a secure technological platform that allows users of CBRS spectrum to identify with precision and share as appropriate access to this scarce public resource,” Pai said. “Doing so effectively and efficiently will speed deployment of services, particularly those involving 5G.”
The citizens broadband radio service band moved another step closer to opening. NTIA’s Institute for Telecommunication Sciences released final test reports to companies that participated in testing on sharing the 3.5 GHz band. “The completed tests will drive progress toward initial commercial deployments in the band, prized for its excellent mix of capacity and coverage capabilities,” blogged Keith Gremban, director of the Institute for Telecommunication Sciences. “With 4G LTE technology for the band available today, industry has already begun to develop specifications to support 5G deployments.” The FCC plans to use the reports to certify that the spectrum access systems are complying with its rules, Gremban said Friday. Commissioner Mike O’Rielly predicts the band will likely be the first mid-band spectrum to come online for 5G (see 1904300208).
Microsoft and Verizon received FCC experimental licenses to do tests in the 3.5 GHz citizens broadband radio service band. Microsoft plans tests at its campus in Redmond, Washington. Verizon said it plans “a series of field tests” using BDRS devices at different locations. “Field tests will be conducted in a production network, in a highly controlled field environment, in order to assist in the development of commercial products,” the carrier said: “The testing will benefit the public interest by enabling the pre-commercial testing of new products outside of a lab environment but in a controlled and managed manner.”
The 6 GHz, citizens broadband radio service and C bands got much of the attention at the Dynamic Spectrum Alliance Global Summit Thursday. Another hot topic was CBRS-like sharing beyond the 3.5 GHz band. FCC Commissioner Mike O’Rielly touched on all three bands during his keynote speech (see 1906270026).
The 3.5 GHz citizens broadband radio service band is unlikely to play a big role in Wi-Fi and instead will provide the unlicensed component of 5G, Martha Suarez, new president of the Dynamic Spectrum Alliance, said in an interview. Suarez recently joined DSA after serving as general director of the National Spectrum Agency in Colombia. DSA’s global summit is this week in Washington.
