Rivada Networks withdrew an application at the FCC to be a spectrum access system administrator and environmental sensing capability operator in the citizens broadband radio service band, said a filing posted Friday in docket 15-319.
In an apparent win for carriers, acting FCC Chairwoman Jessica Rosenworcel is proposing a standard auction for the 3.45-3.55 GHz band, offering the big license sizes favored by national providers. The auction would start Oct. 5 and use an ascending clock format. The FCC also released its open radio access network notice of inquiry and public safety items for the March 17 commissioners’ meeting.
FCC acting Chairwoman Jessica Rosenworcel said 5G issues will be a focus at the March 17 commissioners’ meeting, circulating a draft order to start an auction of the 3.45-3.55 GHz band in early October (see 2102230046). She plans a notice of inquiry opening a “formal discussion” on open radio access networks, the FCC said Tuesday. Rosenworcel announced Monday commissioners will vote on rules for the $3.2 billion emergency broadband benefit program (see 2102220065).
NTIA sent a letter to the FCC Monday providing “more refined geographic parameters” for proposed cooperative planning areas (CPAs) and periodic use areas (PUAs) provided by DOD, tied to an eventual 3.45-3.55 GHz auction. NTIA urged the FCC to release rules and auction the band “as expeditiously as practical.” It's seen as a top priority under acting Chairwoman Jessica Rosenworcel (see 2102190046). The areas aren’t exclusion zones, but “military systems require protection from harmful interference from new non-federal operations, either indefinitely (in CPAs) or episodically (in PUAs), in support of national security missions and to meet readiness requirements,” NTIA wrote. More information will be released as the auction approaches, the letter said: “NTIA and DoD will provide supplemental information to potential bidders similar to the DOD AWS-3 Workbook and NTIA recommends issuing a joint Public Notice, like with AWS-3, with more details on federal notification and coordination.” NTIA reported Monday incumbent informing capability (IIC) time-based sharing holds promise for making more federal spectrum available for commercial use. The sharing system will likely be federalized, “run and administered by NTIA,” the paper said. “NTIA expects that IIC will be deployed over the next few years to support mid-band spectrum sharing predominately between federal systems and broadband wireless carriers using 4G and 5G technology,” it said: “IIC is expected to be a long-term project with iterations that will ultimately allow federal agencies to populate and update in realtime a database with frequency, location, and time-of-use information for systems they deploy.” First steps for testing in the citizens broadband radio service band in this effort are updating the previously developed CBRS portal to a DOD scheduler 11 participating test ranges “and identifying the data collection and security requirements and considerations,” NTIA said. “If successful, NTIA will next evaluate expanding IIC functionality to other 5G mid-band spectrum and ultimately transition the capability to an NTIA operation, allowing us to potentially apply IIC to all federal operations in other bands.” The letter to the FCC said IIC will play a role in 3.45 GHz.
An order establishing rules for a 3.45-3.55 GHz auction appears to be one spectrum item moving under acting FCC Chairwoman Jessica Rosenworcel. She's reluctant to plow into other bands while acting chief, but 3.5 GHz is teed up, and timing is an issue, with an auction having to take place this year, said FCC and industry officials. The big question is whether the FCC will approve a model based on the adjacent citizens broadband radio service or a more traditional licensed model.
Motorola Solutions “strongly supports” an FCC proposal to open the 3.45-3.55 GHz band for shared use. Base rules on those in the citizens broadband radio service band, the company urged in a filing posted Friday in docket 19-348: “Such opportunistic use would significantly increase overall spectrum utilization and ensure that this highly valuable spectrum resource is quickly put to use in more areas, while fully maintaining dynamic incumbent and licensee rights."
Dell’Oro Group sees a slightly less rosy outlook for the citizens broadband radio service band, forecasting $2 billion in investments between last year and 2025, said a Friday report. Fixed wireless and network capacity augmentation dominate investments, the report said. “We remain optimistic about the CBRS opportunity, but we have revised the outlook downward over the near-term to reflect the slower than expected CBRS uptake,” said Stefan Pongratz, vice president-analyst: “This downward adjustment does not change the long-term vision -- we continue to believe that there is an opportunity to improve spectrum utilization while at the same time stimulating innovation for both public and private networks across various industry segments.”
NCTA and its members urged adopting 3.45-3.55 GHz rules consistent with those in the citizens broadband radio service band, in a call with FCC Wireless Bureau and Office of Engineering and Technology staff. “NCTA noted the successful outcome of the 3.5 GHz CBRS auction, and the role that the service rules for that band played in attracting a diversity of auction participants … and encouraging the widespread deployment of the spectrum,” said Tuesday's posting in docket 19-348. Charter Communications, Comcast, Cox and CableLabs participated.
Adopting final service rules for the 12 GHz band will probably take the FCC at least 18 months, with more engineering and other study needed, experts said Monday during an Incompas webinar. Commissioners approved an NPRM 5-0 in January (see 2101130067) at the last meeting under then-Chairman Ajit Pai. Experts said comments will help the FCC decide what action to take.
Adopt aspects of sharing rules in the citizens broadband radio service band in 3.45-3.55 GHz rules, cable interests asked an aide to acting FCC Chairwoman Jessica Rosenworcel. Ensure the rules “provide adequate protection to adjacent CBRS operations,” said a filing posted Tuesday in docket 19-348.
