CBRS

The Rural Wireless Association hailed a letter by three Republican senators saying the FCC should consider countywide tracts for priority access licenses in rural areas in the 3.5 GHz citizens broadband radio service band instead of using partial economic areas (PEAs). The letter urges licensing by metropolitan statistical area in urban communities. The letter was signed by Steve Daines of Montana, John Barrasso of Wyoming and Dan Sullivan of Alaska. They said the FCC should “reject the expansion of geographic licensing areas such as large scale" PEAs. The proposal makes sense, said RWA President Mike Kilgore, CEO of Sagebrush Cellular. “The use of PEAs or other large license sizes in the CBRS context would stifle broadband deployment in rural states.”

CommScope and Ericsson said tests they ran show their equipment designed for the 3.5 GHz citizens broadband radio service (CBRS) band is interoperable. The two said this was one of the first successful interoperability tests using the Wireless Innovation Forum’s release 1.2 specifications. Tests showed CommScope’s spectrum access system and Ericsson’s radio infrastructure with CBRS spectrum support can work together. “Ericsson offers a comprehensive portfolio of CBRS network solutions that will help operators of all sizes deploy in this spectrum quickly and successfully,” said Paul Challoner, Ericsson vice president-network product solutions. “Additional milestones need to be reached for CBRS to become a reality, but we are pleased to complete interoperability testing with CommScope as part of the developmental process.”

Verizon is working with leading vendors and technology companies to test 4G over the 3.5 GHz citizens broadband radio service spectrum at its lab in Irving, Texas, the carrier said Thursday. After initial trials last year, Corning, Ericsson, Federated Wireless, Google, Nokia and Qualcomm are working with Verizon on “end-to-end system testing to further develop the use of this new spectrum,” Verizon said. The companies are testing spectrum access system algorithms from Google and Federated Wireless to make sure they are “consistently providing the best channel match from the SAS database,” said a news release. Also under examination are “data rates, modulations and the customer experience using CBRS spectrum,” the level of interoperability between infrastructure providers “to ensure seamless handoffs between CBRS spectrum and licensed spectrum for customers,” and the performance and data rates of 4G LTE over the spectrum,” the carrier said. The company predicted the band will be available for use next year.

FCC Chairman Ajit Pai told Rep. Robert Wittman, R-Va., he plans to propose the next steps on the 3.5 GHz citizens broadband radio service band “in the coming months.” The FCC posted a March 14 letter to the Virginia lawmaker. “I appreciate your interest in bringing broadband to unserved and underserved communities,” Pai wrote, responding to a November letter. “Your views will be entered into the record of the current 3.5 GHz rulemaking proceeding and considered as part of the Commission's review.”

Nokia demonstrated its prowess in the 3.5 GHz citizens broadband radio service band last week at the FCC, the company said in a filing in docket 15-319. Nokia is the “only company developing an end-to-end solution,” it said. It alone has “a fully virtualized, cloud-based, scalable Spectrum Access System (SAS), a Domain Proxy, an Environmental Sensing Capability and Citizens Broadband Radio Service Devices (CBSDs),” Nokia said. Nokia officials said they met with aides to all the commissioners, except Chairman Ajit Pai, and with staff from the Wireless Bureau and Office of Engineering and Technology. “Nokia highlighted its advanced product development by demonstrating over-the-air live transmissions from CBSD small cells authorized by the Nokia SAS and the ease with which End User Devices could connect to the Nokia network and seamlessly access rich video content.” Nokia said it also demonstrated the technology at NTIA.

A big test of NTIA efforts to incentivize spectrum sharing between industry and federal agencies and the agencies maximizing their use of their spectrum assignments will come over the next few years with the rollout of the 3.5 GHz citizens broadband radio service band, said NTIA Administrator David Redl Wednesday at Satellite 2018. NTIA is looking at the 3450-3550 MHz band as a candidate for potential commercial use, Redl said (prepared remarks here). He said DOD plans to ask for money through the Spectrum Relocation Fund to study the band (see 1802260047). Redl said appropriations have been provided to study proposed reallocation of the 1300-1350 MHz band. Many think reallocation of the 1.3 GHz band is probably a top NTIA priority (see 1802230052).

Electric utilities urged the FCC to keep census-tract sized geographic licenses for priority access licenses (PALs) in the 3.5 GHz shared band. The Edison Electric Institute reported on a meeting between members and Commissioner Mike O'Rielly, overseeing the FCC’s look at changing the rules for the citizens broadband radio service band. If the FCC approves larger PALs, utilities and other critical industry companies won’t be able to compete with wireless carriers for the licenses, EEI said in docket 17-258. “The industry is investing approximately $100 billion per year on building new infrastructure,” EEI said. “Much of this investment is targeted at deployment of the Smart Grid/Energy loT. Not only will this help improve grid safety, reliability and security, it will also facilitate the offering of new services related to Smart Communities, microgrids, electric vehicles and a host of other new consumer services. The current spectrum that electric utilities have is not sufficient to meet the growing capacity requirements.” General Electric recently stressed keeping the current license sizes (see 1802140055).

General Electric executives said they spoke with Rachael Bender, aide to FCC Chairman Ajit Pai, on why the FCC should keep census tract-sized licenses in the 3.5 GHz citizens broadband radio service band. GE has been a leading proponent of keeping the current license sizes, citing the importance to the industrial IoT (see 1802140055). “Spectrum is an essential input for myriad activities around the United States that generate important economic, social, safety, and other public interest benefits,” said a filing in docket 17-258. “GE, its industrial and critical-infrastructure customers, and other diverse users will make intensive use of their licensed spectrum with targeted, localized wireless network deployments that will generate a wave of new cutting-edge jobs and economic growth in a mix of urban, suburban, rural, and remote areas.”

CTIA urged the FCC to act “quickly” to modify the priority access license rules for the 3.5 GHz citizens broadband radio service band. The most important changes are auctioning PALs for a 10-year term with an expectation of renewal and in sizes larger than census tracts, CTIA said in meetings with aides to Commissioners Mike O’Rielly and Brendan Carr. Verizon, AT&T and T-Mobile officials were also there. The changes would give licensees “greater certainty and encourage investment,” CTIA said in docket 17-258. “Making these targeted reforms to the CBRS framework will help unlock the benefits that 5G will bring to the U.S. economy -- benefits that were not foreseen when this proceeding was originally undertaken -- by providing faster speeds and additional bandwidth needed to support the Internet of Things.”

The FCC tentatively approved the first environmental sensing capability (ESC) operators for the 3.5 GHz citizens broadband radio service band, moving launch of the CBRS sharing band another step closer to reality. The ESC operators allow sharing in coastal areas, protecting Navy radars. The four are: CommScope, Federated Wireless, Google and Key Bridge Wireless. All must now submit their systems for testing before final certification, the FCC said. “The ESC operators will manage a sensor system designed to detect the presence of federal incumbent radar transmissions in the 3550-3650 MHz portion of the 3.5 GHz Band and communicate that information to one or more Spectrum Access Systems (SAS) in accordance with the Commission’s rules,” said the notice by the Office of Engineering and Technology and the Wireless Bureau. “The ESC will enable more dynamic sharing between federal and non-federal users in the band, particularly in coastal areas.” Commissioner Mike O’Rielly last week said approval of the operators was imminent (see 1802130041). “Today’s important step gets us closer to permitting 3.5 GHz use in coastal areas where a huge population of Americans live and attracting necessary investment for equipment manufacturing and network deployment," O’Rielly said Wednesday. Ruckus Networks Wednesday announced release of 3.5 GHz LTE access points and associated cloud-based subscription services. The 3.5 GHz market is likely to be huge, Ruckus said. “The Ruckus LTE portfolio enables enterprises to deploy private LTE networks to ensure high quality-of-service (QoS) for critical business applications,” said a news release.
