The FCC Wireless Bureau sought comment Thursday on a request by the University of Utah for citizens broadband radio service rules for its POWDER (Platform for Open Wireless Data-driven Experimental Research) platform, established to “enable innovation and research associated with wireless systems and spectrum use.” Comments are due July 18, replies July 25, in docket 22-257. The university asked for a waiver to use software-defined radio equipment to interact with the spectrum access system operator “within the POWDER Platform Innovation Zone” and for other exceptions to rules for the band. The platform is used for research by the university, in partnership with Salt Lake City and the Utah Education and Telehealth Network.
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 FCC’s newly reconstituted Technology Advisory Council met for the second time Thursday, dedicated to exploring 6G, as directed by FCC Chairwoman Jessica Rosenworcel. She and TAC members said 5G is still in early stages, but it’s not too early to focus on the next generation of wireless. TAC heard updates from its working groups on the work they have done so far during a virtual meeting.
Major industry players expected to play in the 2.5 GHz auction, which starts July 29, were on the list of bidders with complete applications to participate in the FCC’s next big 5G spectrum sale, the FCC said Thursday. AT&T, Dish Network, bidding as Carbonate Wireless, T-Mobile and UScellular are among the 39 with complete applications. Verizon put in an application, deemed incomplete, joining 53 bidders on that list. There appears to be more interest in this auction than in the 3.45 GHz sale, which had 42 applications, while the C-band auction had 74 applications filed. Smaller players are among the qualified bidders, with 17 seeking rural provider bidding credits and nine small business credits. Questions continue over the extent to which small players will jump in or T-Mobile will dominate the auction (see 2204140062). T-Mobile has a dominant position in the band since its buy of Sprint, and is using 2.5 GHz for its 5G rollout. “At first glance, the list of bidders for 2.5 GHz auction (whether qualified or not) does not reveal too many surprises,” emailed Sasha Javid, BitPath chief operating officer. “Submitting an application does not mean that Verizon or AT&T are necessarily interested in bidding for this spectrum,” he said: “It is a low-cost way to muddy the waters for bidders that are truly interested in acquiring the spectrum. If there is one initial takeaway, it is that this auction did not get as many prospective bidders as the [citizens broadband radio service] auction, which also featured smaller county-sized licenses.” The 2020 CBRS auction attracted 271 qualified bidders (see 2007200049). Those with complete short-form applications must submit upfront payments June 23, to be deemed qualified bidders. Others must resubmit their applications, and make an upfront payment, by the same date.
Dynamic spectrum sharing is a slow, expensive process, and though it has a role to play in meeting growing needs for mobile spectrum, it's not the silver bullet, Peter Rysavy, president of wireless tech consultancy Rysavy Research, said Wednesday in a Georgetown University Center for Business and Public Policy presentation. Beyond more spectrum, the U.S. also needs denser networks and better antenna technology to increase capacity, he said.
Private 5G is in the nascent stage, but adoption is starting to accelerate, speakers said during a Fierce Wireless virtual conference Monday. Speakers said the network often has to be tailored for the individual business and has to go beyond a “turn-key” solution.
Private 5G networks are in early stages, with no consistent spectrum available worldwide, experts said during an RCR Wireless webinar Thursday. Speakers warned that no one-size-fits-all solution will meet the needs of companies.
The NFL told the FCC it didn’t need to use an agency waiver to use citizens broadband radio service spectrum to operate its in-stadium, coach-to-coach communications system during a game in which it lost connection with a spectrum access system manager. In a single incident in Atlanta Nov. 18, a fiber cut to the Lumen network "took the Lumen ISP connection down at that stadium,” the league said: “The Verizon LTE system was automatically switched in and there was never any loss of communication with the SAS.” The NFL said “the level of ISP redundancy implemented in each stadium is sufficient to make it highly improbable that the CBRS system will be operated pursuant to the waiver.” The filing was posted Monday in docket 21-111.
Dish Network's mobile 5G network is up and running in Las Vegas, albeit with mixed results, and the company will easily meet its June goal of reaching 20% of the U.S. population, executives said Thursday, announcing its 2021 year-end results. "When it works, it works pretty well," Chairman Charlie Ergen said. He said network optimization and working with handset manufacturers to ensure Dish frequencies are in their hardware are still to be done before broad commercial launch, plus fixing of some regulatory issues like Enhanced 911 access.
The FCC approved Key Bridge to be an environmental sensing capability (ESC) operator in various markets, for the citizens broadband radio service, said a notice in Tuesday’s Daily Digest. The Wireless Bureau and Office of Engineering and Technology gave preliminary clearance earlier but told the company to submit its sensing software to NTIA for retesting (see 2007140055). “Based on these results, we find that Key Bridge has satisfied the retesting condition and is approved for full commercial operation of their ESC,” the FCC said in docket 15-319.
Charter Communications will ramp up broadband speeds throughout its network this year with more high-split deployments, CEO Tom Rutledge said Friday as the company announced Q4 results. The high-split upgrades allow symmetrical gigabit speeds or multi Gbps downstream, and are cheaper than network capital spending such as new nodes, he said. Rutledge said Charter will expand its 800,000-mile network by 100,000 miles over the next five years through Rural Digital Opportunity Fund funding. He said beyond RDOF, the company is using broadband stimulus money and Infrastructure Investment and Jobs Act funding to reach other rural areas, plus expanding into areas adjacent to subsidized builds. That rural spending, including RDOF and other subsidized rural projects, will be about $1 billion this year in capital expenditures, said Chief Financial Officer Jessica Fischer. Rutledge said Charter continues to work on DOCSIS 4.0 tech development, with recent tests delivering speeds of more than 8 GB downstream and more than 6 GB upstream. He said Charter is rolling out its 5G hybrid mobile network operation using citizens broadband radio service small cells in an unspecified market, letting people connect to CBRS small cells when they're not in Wi-Fi reach. Charter said it ended 2021 with 28.1 million residential broadband customers, up 1.1 million year over year and 15.2 million residential video subscribers, down 400,000. It reported 3.4 million residential mobile lines, up 1.1 million, and 8.6 million residential voice customers, down 600,000. Revenue was $13.2 billion, up $600 million. The stock closed up 5.3% at $590.47.
