CBRS

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.

FCC Commissioner Mignon Clyburn remains strongly opposed to any changes to the rules for the 3.5 GHz citizens broadband radio services band, which would lead to larger license sizes for priority access licenses (PALs), said Louis Peraertz, her wireless aide, at a panel hosted by General Electric Wednesday. A GE executive said the band is critical to U.S. leadership of the industrial IoT. Tuesday, advocates of larger license sizes spoke at an AT&T-sponsored event (see 1802130041).

Commissioner Mike O’Rielly, who has led the FCC push to change 3.5 GHz communications broadband radio service rules, said Tuesday he's not convinced the agency should significantly reduce the geographic size of the priority access licenses (PALs) that will be sold in an auction. It was always clear the 3.5 GHz band has “great potential, but I do not believe we have the solution quite right yet,” said Joan Marsh, chief regulatory and state external affairs officer at AT&T, which held the event.

A large group of wireless ISPs and other businesses said the FCC shouldn't tamper with rules for the 3.5 GHz citizens broadband radio service band. “For many of us, CBRS will allow us to develop our own networks and deploy technologies that will improve the experiences of our customers and connect the unconnected in rural America,” said a filing in docket 17-258. “CBRS is ready for business, and we are here to tell you that business is ready for CBRS.” The FCC may approve a compromise (see 1801310067).

While staffers for FCC Chairman Ajit Pai aren’t signaling yet what he will recommend on the contentious question of what to do about priority access licenses in the 3.5 GHz citizens broadband radio service (CBRS) band, growing industry speculation is Pai will propose a compromise. Rather than auction all the PALs on a census-tract basis, or as much larger partial economic areas, the FCC would take a varied approach. It would offer some of the seven PALs in each market as census tracts or a similarly small license size and others as PEAs or possibly county-sized licenses.

General Electric, active in the past on the 3.5 GHz citizens broadband radio services band, met FCC Chairman Ajit Pai to urge the agency to stick with a plan to license priority access licenses on a census-tract basis. The FCC is examining whether it should instead license the PALs in larger sizes, as proposed by wireless carriers (see 1710240050). “Census-tract licensing is critically important to GE and its industrial and critical-infrastructure customers, since the CBRS band is an ideal spectrum platform for the ‘Industrial Internet of Things’ (IIoT) and can serve as a unique catalyst for accelerated growth throughout the U.S. industrial and manufacturing sector,” GE filed Wednesday in docket 17-258. “Robust IIoT applications require significant spectrum, secure localized networks, and specialized technology, and today industrial and critical-infrastructure entities are typically unable to obtain the necessary wireless functionality from commercial mobile operators on a cost-effective basis.” Also on 3.5 GHz, GeoLinks CEO Skyler Ditchfield and others from the wireless ISP explained the importance of the band to his company. Ditchfield met over two days with officials, including all FCC members other than Jessica Rosenworcel. “The Company explained the challenge of operating on unlicensed bands such as 5 GHz in urban environments, where overcrowding can slow and disrupt service,” said a Wednesday filing. “It could provide better and more reliable service, including Gigabit service to the home, if the Company had access to sufficient licensed or lightly licensed spectrum.”

The FCC should stick with rules as they are for the 3.5 GHz citizens broadband radio service band, Dynamic Spectrum Alliance President Kalpak Gude told an aide to Chairman Ajit Pai. DSA said it opposes both longer license terms and bigger geographic licenses for priority access licenses (PALs) that are the licensed component of the band. In October, commissioners agreed to seek comment on revising the rules (see 1710240050). “The current three-year terms are better connected to return on investment than the ten-year terms as mentioned in the NPRM, and that renewability is counterproductive to the goals the Commission has articulated for the band,” DSA said in docket 17-258. “Both changes would create a need for more regulatory oversight in terms of build-out requirements and enforcement. Shorter terms with no right of renewal will allow for a much more market driven structure.”

Ruckus hopes the FCC will move soon to finalize approvals for devices that can use the 3.5 GHz citizens broadband radio service band, as well as approvals of the first spectrum access system (SAS) administrators and environmental sensing capability (EMC) operators, Dave Wright, director-regulatory affairs and network standards, told us. “There is a tremendous amount of existing investment, momentum and anticipation in the band,” Wright said in an email. “Any further delays risks stalling the ecosystem.” There have been reports of movement on rules for the band (see 1801020046). “Ruckus is encouraged by both the quantity and quality of the comments that have been submitted to this NPRM, especially considering that the filing deadline was between Christmas and New Year’s,” Wright said. New commenters “representing a variety of industries such as transport, energy, and rural providers” weighed in, he said. Comments on priority access licenses “echo the previous positions that had been taken,” but others “offered fresh thoughts on secondary market mechanisms (leasing and partitioning) and performance requirements,” he said. “We expect these ideas will receive additional attention in the reply phase.”

NAB raised concerns about interference if the FCC makes technical changes to rules for the 3.5 GHz citizens broadband radio service (CBRS) band. Other commenters said the FCC should minimize changes to the rules approved three years ago. The FCC approved the initial 3.5 GHz NPRM in 2012 (see 1212130044), setting up an experimental three-tiered access and sharing model made up of federal and nonfederal incumbents, priority access licenses (PALs) and general authorized access users. In October, commissioners agreed to seek comment on revising the rules (see 1710240050).
