FCC Commissioner Mike O’Rielly said at a Citizens Broadband Radio Service Alliance meeting Tuesday the 3.5 GHz band will likely be the first mid-band spectrum to come online for 5G, next year. “Left on the Commission’s plate to get CBRS fully operational is concluding the review and approval of the Spectrum Access Systems, or SAS, and Environmental Sensing Capability systems, commonly referred to as the ESC,” O’Rielly said. “I have been working with the leadership of the CBRS Alliance to help make sure this process stays on track. While some steps experienced unfortunate delays and this process has taken far longer than anyone would have liked, it appears to be nearing the end.” The FCC this week approved the first ESCs, he said. “I must admit that I never expected it to leapfrog ahead of the SAS testing and development process,” he said: “Unfortunately, the SAS testing is still in progress.” Monday, staff OK'd environmental sensing capabilities of CommScope, Federated Wireless and Google in the 3550-3650 MHz portion of the 3550-3700 MHz band. "These ESCs may operate in areas covered by registered and approved ESC sensors subject to ... compliance obligations," said the public notice.

The CBRS Alliance and Small Cell Forum agreed to “cooperate closely” on the citizens broadband radio service band rollout, on a "variety of initiatives related to the wide-scale adoption of small cells, network densification, and the development, commercialization and adoption of OnGo-certified solutions,” they said Wednesday. Collaboration areas “include investigating multi-operator solutions in the 3.5 GHz band, defining indoor solution architectures for densification, and exploring the international opportunity for Spectrum Access System-coordinated shared spectrum.”
The FCC is continuing to prepare for the 24 GHz auction and future auctions, including pushing forward on the C band and other bands being looked at for 5G. The 28 GHz auction closed Thursday. Nevertheless, the agency remains constrained in how much staff can do as the longest shutdown in federal history continues. “Staff continues to work on future auctions,” a spokesperson emailed Thursday.
The Citizens Broadband Radio Service Alliance is adding members like the Wireless ISP Association, working with ATIS, and released a certification tool developed with Radisys, the CBRS alliance said Monday. “Now with more than 120 members, the Alliance is seeing a new set of organizations beginning to engage in the OnGo ecosystem,” it said. Cisco Wireless Chief Technology Officer Matthew MacPherson joined the alliance’s board, the group said.
The Global Mobile Suppliers Association says LTE-unlicensed and LTE-assisted access (LAA) are gaining momentum, consulting engineer Steven Crowley blogged. GMSA says 32 operators are investing in LAA across 21 countries, with six announcing launches. Another 11 operators announced investments in LTE-U networks. And 120 devices support LTE in unlicensed spectrum including the citizens broadband radio service band, Crowley noted. “LTE in unlicensed and shared spectrum remains at an ‘early stage’ worldwide with interest ‘high.’”
Google remains hopeful the 3.5 GHz band citizens broadband radio service band will open for business in the first half of 2019, said Andrew Clegg, spectrum engineering lead, at the Next Century Cities conference Tuesday. Clegg predicted sharing will remain a key theme under President Donald Trump and will hit new heights with use of the 3.5 GHz band. The CBRS band will benefit rural and urban consumers, Clegg said: “It’s going to add a lot of fill-in capacity for urban systems. It’s a great complement to 5G.” In rural markets, wireless ISPs now have access to 50 MHz in the band and will be able to use up to 150 MHz, he said.
With 2019 dubbed the year of 5G and companies vying to compete in the new citizens broadband radio service and other bands, the federal shutdown comes at a bad time, industry officials said last week. Every cellphone, TV, computer or other device sold in the U.S. emits a unique RF signature and must be cleared by the FCC. With the agency mostly shuttered as of Thursday, those clearances can no longer take place.
The Wireless ISP Association and the Utilities Technology Council jointly told the FCC the record shows overwhelming support for their joint request asking the FCC to waive requirements that 3650-3700 MHz licensees complete the transition to Part 96 citizens broadband radio service rules by April 17, 2020 (see 1812040002). Reply comments were due at the FCC Friday. CTIA and NCTA were among the commenters opposing a blanket waiver.
The American Petroleum Institute supported a waiver request by the Wireless ISP Association and the Utilities Technology Council on a pending 3.5 GHz requirement. WISPA and UTC asked the FCC to waive requirements that 3650-3700 MHz licensees complete the transition to Part 96 citizens broadband radio service rules by April 17, 2020 (see 1812040002). Waiver would benefit the oil and gas industry and “given the nature of CBRS and its relation to the smaller 3650-3700 MHz band … would not encumber Priority Access,” API filed, posted Monday in docket 18-353.
