Industry officials said it appears likely commissioners will consider a long-awaited NPRM on the shared 3.5 GHz band at their Oct. 24 meeting. That’s not a certainty since FCC Chairman Ajit Pai won’t circulate items until Tuesday. The FCC earlier moved up the date of the meeting by two days. Big-ticket items like net neutrality aren't expected at the October meeting, the officials said Monday. There's uncertainty about whether media ownership will get a vote.
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.
The 800 MHz Transition Administrator clarified the Canadian border region (CBR) enhanced specialized mobile radio (ESMR) dividing line at the instruction of the FCC, said a filing. The TA said it determined the highest frequency occupied by a non-ESMR licensee in each of the six CBRs “by reviewing replacement frequency proposals for 800 MHz licensees, amendments to frequency proposals, and licensing records in the FCC’s Universal Licensing System.” The TA said it then identified the dividing line as “the frequency 12.5 kHz above the highest frequency licensed by a non-ESMR licensee in each CBR.” The TA has assisted with the 800 MHz rebanding, underway since 2004, designed to address interference to public safety in the 800 MHz band.
Verizon, Ericsson, Qualcomm Technologies and Federated Wireless said they were the first to demonstrate the successful use of LTE with carrier aggregation in the 3.5 GHz shared band. The demonstration was in an Ericsson lab in Plano, Texas, and offered “end-to-end” Citizens Broadband Radio Service communications “using 2x20 MHz LTE carriers on the CBRS band 48,” said a joint news release. "The use of CBRS spectrum greatly advances our work in emerging spectrum bands,” said Nicola Palmer, Verizon wireless chief network officer.
The Dynamic Spectrum Alliance (DSA) told the FCC that by its tabulation “the vast majority” of comments oppose proposed changes by CTIA and T-Mobile for the 3.5 GHz shared band. Some 84 percent of comments in the initial comment round were against CTIA and 89 percent against T-Mobile, DSA said. T-Mobile and CTIA defended their proposals. One suggestion for priority access licenses (PALs) in the 3.5 GHz shared band that could have legs is NCTA's and Charter Communications’ push for a middle-ground on license sizes, industry officials said. Replies were posted Wednesday in docket 12-354. Termed by the FCC Citizens Broadband Radio Service, CBRS operations are expected to start even amid the controversy (see 1708080019).
The opening of the 3.5 GHz shared band isn't expected to be delayed due to problems industry had getting waveforms from the Navy, Lee Pucker, CEO of the Wireless Innovation Forum (WInnForum), told us Tuesday. Other complications are possible, other industry officials said. But Pucker, who heads the group the FCC tasked with overseeing the technical work on the band, said things are moving ahead. The Citizens Broadband Radio Service (CBRS) is expected to offer licensed spectrum and unlicensed for Wi-Fi and use by wireless ISPs.
PCTel joined the CBRS Alliance, a group promoting use of the shared 3.5 GHz Citizens Broadband Radio Service band. “PCTEL and the CBRS Alliance believe that efficient use of this underutilized 3.5 GHz spectrum will expand coverage and capacity to meet growing wireless data demands,” the company said in a Thursday news release. “PCTEL scanning receivers currently support LTE network testing on the 3.5 GHz CBRS band.”
Google opposes proposed changes CTIA and T-Mobile sought to rules for the 3.5 GHz shared band, saying the FCC needs to keep its eye on stability. Verizon supported the CTIA petition over that of T-Mobile, consistent with its earlier stance (see 1706200081). Comments were due on the petitions Monday, and dozens filed in docket 12-354, as the FCC considers changes to rules for the Citizens Broadband Radio Service. Commissioner Mike O'Rielly discussed the rules Tuesday (see 1707250049).
Charter got a temporary license from the FCC Office of Engineering and Technology to run tests in the 3650-3700 MHz band. Tests are to start July 1 and run through the start of 2018, said a report posted by the FCC. The application's purpose is to test “a variety of experimental equipment,” the document said: “The testing will evaluate coverage, capacity, and propagation characteristics in the 3650-3700 MHz band. The proposed operations will advance Charter’s understanding of technology and network potential in the band and will advance deployment of fixed and mobile services.” Tests also will look at coexistence of devices in that band and in the FCC’s adjacent Citizens Broadband Radio Service band, said a filing by the cable ISP. It said it's working with Federated Wireless, one of coordinators in the CBRS band. The tests will take place in the Tampa, Florida area.
The fight over the future of the 3.5 GHz band is heating up, with T-Mobile breaking with other carriers to propose its own version of rule changes. CTIA recently also proposed revised rules (see 1706190067). A coalition of companies and groups concerned about protecting unlicensed use of the band asked the FCC to not make major changes to the rules, which took years to develop. The filings come as Commissioner Mike O’Rielly takes the lead on changing the rules to better assure the band will be a success (see 1704190056).
Seventeen companies and associations urged the FCC to act to open the 3.5 GHz band and said it would slow deployment if it made major rule changes. Commissioner Mike O’Rielly is working on revisions (see 1704190056). The Thursday letter says small changes aren't a problem.
