May 8, 2021—The Federal Communications Commission on Friday took three actions to expand access to the 3.5 GigaHertz (GHz) band in American territories to expedite 5G deployment in the regions.
Puerto Rico, Guam, and American Samoa have notably lacked reliable 5G coverage in the past, but the FCC said it was taking steps to ensure that they will not be left behind as the rest of the country continues to roll out 5G,.
“No matter who you are or where you live, you need access to modern communications to have a fair shot at 21st century success,” Chairwoman Jessica Rosenworcel said in a statement.
The FCC acted to clear a way for commercial access to the segment of Citizens Broadband Radio Service that overlaps with the 3.5 GHz band. It did so by approving deployment and coverage plans for updated devices with environmental sensing capability—colloquially known as ESC sensors—for CommScope Inc, Google, Federated Wireless Inc, and Key Bridge Wireless LLC, in Puerto Rico and Guam.
Thos entities operate as spectrum access system coordinators. SAS is an automated system that coordinates spectrum use between incumbent operators and those with lower priority.
Additionally, the FCC approved Federated Wireless to expand the company’s SAS operations to operate within the CBRS portion of the 3.5 GHz band. These systems are used in bands that utilize a shared use model, such as the CBRS. This action will bring the CBRS to American Samoa for the first time.
These SAS systems will work in tandem with the ESC sensors to facilitate efficient communication between the different tiers of operators in the CBRS.
The FCC also conditionally approved the SAS applications for Fairspectrum LLC, Nokia, and RED Technologies. This action served as a step in expanding the use of the shared spectrum model—a move that is aligned with Rosenworcel’s stated agenda.
Dish Requests Temporary Authority to Use 600 MegaHertz Band Licenses for 5G Test in Las Vegas and Denver
Dish said it needs non-contiguous 600 MHz band licenses to test open-RAN 5G network in two markets.
WASHINGTON, September 9, 2021 – Dish Network is asking the Federal Communications Commission to grant it a temporary license to use 600 MegaHertz (MHz) spectrum band licenses owned by another licensee for 5G tests in Las Vegas and Denver.
Dish said in a Wednesday submission to the FCC that Bluewater Wireless II, the owner of the 600 MHz spectrum band in question, has consented to allow Dish to use the spectrum under a regime called a special temporary authority.
Dish said it requires Bluewater’s spectrum licenses in the two cities to test and validate equipment for its 5G broadband network, using open radio access network technologies. The company said it needs the licenses to test carrier aggregation, where using its own licenses would be insufficient, because the two spectrum blocks cannot be contiguous.
“DISH anticipates needing more low-band spectrum in some markets to meet customer demand in the future,” the company said in its submission. “When and if additional 600 MHz spectrum becomes available, either when the Commission auctions unassigned spectrum or through future partnerships, DISH plans to use carrier aggregation at the market level to combine multiple 600 MHz assets to add capacity and improve data throughput speeds.”
“Grant of this STA will deliver important public interest benefits,” the company added. “In particular, the STA will enable DISH to put to use certain spectrum licensed to Bluewater that is not yet deployed.”
The test will end no later than the end of this year and the spectrum will only be used for testing and not for commercial purposes, Bluewater added in a letter to the FCC consenting to the arrangement.
The Denver-based company said it completed its first fully open RAN-compliant network communication in December 2020.
Dish announced that it was taking sign-ups for its 5G service in June, with the first city to get its so-called Project Gene5is being Las Vegas, Nevada.
Dish secured mobile wireless assets in a deal that allowed T-Mobile to absorb Sprint and entered the market in 2020 with the purchase of Boost Mobile and Ting Mobile. Dish has been widely expected to deliver wireless service that would add competition back in after the acquisition of Sprint.
The company announced this month that it is also purchasing Gen Mobile, a pre-paid and low-cost mobile service company, through its Boost brand.
Earlier this year, Boost bundled its K Health telehealth service in with its mobile service.
SpaceX, Engineers Clash over Whether 12 GigaHertz Band Can Be Shared with 5G Operators
Competing submissions to the FCC show the friction over valuable mid-band spectrum.
August 10, 2021 – Research commissioned by RS Access showing the mid-band 12 GHz spectrum, a band used by satellite service providers, can be shared with 5G operations has elicited a scathing rebuke by SpaceX — and the engineering firm behind the study is responding in kind.
The FCC is currently studying the possible sharing of the band between satellite providers and mobile wireless carriers for 5G. Broadband Breakfast held a panel discussion in July, which included arguments for and against the spectrum’s flexible use. RS Access’ V. Noah Campbell mentioned the technical study in question during the session, by RKF Engineering Solutions, LLC.
In a filing to the Federal Communications Commission last week, however, SpaceX alleges RKF’s technical study is a “fatally flawed” analysis that washes over the interference consequences that will allegedly happen if the spectrum is shared with 5G operations.
To address interference concerns, the engineering study drew three main conclusions: low-earth orbit satellite user terminals, which SpaceX’s Starlink fleet uses, can reject 5G signals; technology used by mobile wireless networks will direct energy toward handsets, not satellite terminals; and 5G networks will be used largely in higher population areas, whereas Starlink will focus on low-density, largely rural, areas. It also said that without coordination, interference possibilities will affect less than one percent of next-generation satellite operator terminals.
But SpaceX said these conclusions assume that the 5G build-out will only occur in urban areas and limit the next-generation satellite service providers from operating in those areas. The company said while Starlink is “designed to optimize for rural areas initially, it will provide service in urban areas.” It also claims that there will be interference suffered by the satellite terminals on the ground to cause disruptions in service, and ultimately, thousands of customers could be impacted.
SpaceX notes that the $900 million it won in December from the FCC’s $9.2-billion Rural Digital Opportunity Fund – which is currently being reassessed due to complaints of possible overbuilding – backs the fact that urban coverage is part of its agenda.
The company said it has over half a million back orders in its first six months of beta testing its Starlink service with only a third of its LEO fleet deployed (it has over 1,400 satellites launched). It also said it has applied to increase the number of licensed user terminals to 5 million.
RKF engineering firm responds
But RKF said in a filing to the FCC on August 9 that SpaceX misread the study to “find harmful interference where none may exist.” It said the study finds that a 5G network with zero coordination among users of the spectrum would impact fewer than one percent of next-generation satellite terminals. With coordination, such possible interference incidences would be reduced even further, it adds.
RKF, founded in 2001 and known by the last name initials of its founders Phil Rubin, Ted Kaplan, and Jeff Freedman, said this is the only engineering study of its kind in the FCC docket and no company has refuted it.
Other complaints in the Tuesday filing include RKF’s claim that its study did not say that the 5G build-out will only occur in urban areas, noting that the study surveyed less populated areas and found that demand is greatest in more densely populated areas. It also said its study does not preclude SpaceX from operating in any part of the country. It added that SpaceX operations in urban areas with 5G networks is “still readily achievable.”
“SpaceX’s inexplicable response to our rigorous, data-driven engineering study on coexistence in the 12 GHz band is so egregiously inaccurate that we as a firm felt it needed a direct response,” David Marshack, chief operating officer of RKF, said in a statement to Broadband Breakfast.
“Though our firm has often been called on to perform analyses in Commission proceedings, rarely has our firm engaged directly in the FCC docket on its own behalf. But in multiple Commission filings, SpaceX has impugned RKF’s integrity with baseless allegations and brazen misrepresentations that have made engaging on the record necessary.
“The engineering analysis clearly shows that coexistence between satellite and terrestrial 5G in the 12 GHz band is highly feasible,” the statement added. “Any claim to the contrary is a misunderstanding of our findings which show that a 5G network with zero coordination would impact fewer than one percent of NGSO terminals.”
Dish Network — the beneficiary of mobile wireless assets from the T-Mobile-Sprint merger and which is using said assets to develop its 5G network – said in a January filing that it hopes the commission would find a way to open the band for 5G use.
Since the other satellite-using C-band spectrum has already concluded its auction, the supply of critical mid-band spectrum for 5G is diminishing. Last month, RS Access filed a study by Roberson and Associates with the FCC claiming that the 12 GHz spectrum is “highly favorable for 5G, resembles lower-mid band frequencies, and can rapidly accelerate 5G deployment nationwide.”
Companies Clash Over Spectrum Sharing in 12 GHz Spectrum Band
Satellite service provider Dish, which is open to 12 GHz for mobile, recently signed a network sharing deal with AT&T.
July 19, 2021—While some experts believe that the 12 GHz spectrum band is a natural space for 5G to expand into, others remain unconvinced that doing so would not interrupt incumbent usage.
Broadband Breakfast convened a panel of experts on July 14 as part of its Broadband Breakfast Live Online event on “Spectrum for 5G, LEOs and the Future of the 12 GigaHertz (GHz) Band.”
Though the 12 GHz band has been used up to this point for low-earth orbit satellite networks, there has recently been debate over converting some of the band for terrestrial mobile use—a move that has frustrated some incumbents who assert that terrestrial mobile use would interfere with satellite services.
Eric Graham, the director of government and regulatory engagement for satellite provider OneWeb, described the effort to expand usage of the 12 GHz band as uncertain at best, arguing that new mobile devices operating in the band would create harmful and unpredictable interference.
“We use a very low level of power in the [non-geostationary-satellite orbit, fixed-satellite service] world,” Graham explained. “By the time the satellite signal reaches Earth from 1,200 kilometers away, that signal is very weak, and a terrestrial mobile device—your smartphone or other device—will wipe out that signal to the user terminal.”
According to Graham, there was a consensus at the conclusion of the reply comment round on this issue at the FCC. “Everyone had agreed that it was impossible for terrestrial mobile to coexist with the incumbents.” He stated that it has only been within the last year that proponents of expanding access to the band “found a way to create a study that purports to support coexistence.”
The argument for flexible use
Not everyone was convinced of Graham’s position, however. Co-founder and CEO of RS Access Noah Campbell argued that coexistence is not only possible but is vital to 5G deployment in the U.S. RS Access penned the first technical feasibility study that they argue proves that the 12 GHz band could host both mobile terrestrial devices and satellite services.
Cambell pointed out that the 12 GHz band is unique because it represents a significant swath of spectrum (500 MHz), despite only being licensed for one way service.
“In the context of 2021’s technology landscape that is absolutely insane,” he said. “[The FCC] would never license a frequency that way ever again. So, these are antiquated rules that really do not make sense from a technology standpoint, and do not make sense from a usage standpoint.”
Jeffrey Blum shared Cambell’s assessment of the 12 GHz. As the executive vice president for external and legislative affairs for Dish Network, Blum indicated Dish’s willingness to work with incumbents in the band.
“We do not want to fight, we want to share,” he said. Dish itself is a 12 GHz incumbent and has been operating satellites in the band since 1995 for over eight-million subscribers.
“We would not want to do anything at all to jeopardize our eight-million subscribers. We are confident that [[non-geostationary-satellite orbit, direct broadcast satellite], and mobile terrestrial uses can coexist.”
In fact, on the day of the live event, Dish announced a 10-year, $5-billion network sharing deal with AT&T to bolster its fledgling 5G network, according to a regulatory filing.
The deal would see AT&T provide support for Dish’s Boost Mobile by providing it with voice and messaging services. To do this, AT&T would be able to use bands of spectrum to which Dish holds licenses—both for their own use and Boost Mobile’s.
If the rules are successfully changed by the FCC, this would include the 12 GHz band.
Dish was able to obtain mobile wireless assets as part of a regulatory deal to approve the T-Mobile-Sprint merger that was completed last year.
In June, Dish announced a deal with Dell Technologies to launch the 5G network based on open radio access network and cloud technologies. Dish began accepting sign-ups for its 5G network that month.
Blum also struck back against the press’s title of the “Battle of the Billionaires.” He stated that DISH does not view the situation that way, and that this effort should only be viewed as a method to update outdated rules.
He pointed to all the technological advancements that have been made since the rules were originally established and, coupled with the need for the U.S. to lead 5G deployment, “the importance of 5G and 5G leadership to our country is essential,” Blum said.
The FCC still must make a decision regarding the 12 GHz band. Though Acting Chairwoman Jessica Rosenworcel has historically been supportive of spectrum sharing initiatives, she has not yet publicly indicated whether she would support such an initiative in the 12 GHz band.

Wednesday, July 14, 2021, 12 Noon ET — “Spectrum for 5G, Low-Earth Orbit Satellites and Sharing the 12 GigaHertz (GHz) Band”
The 12 GigaHertz (GHz) band of radio frequency spectrum has emerged as a flashpoint in the debate over 5G services versus satellite technologies. Proponents of spectrum sharing believe now is the time to open up the 12 GHz band for more intensive broadband uses. But some satellite services are very much opposed. And the Federal Communications Commission is currently considering the arguments. Come to the July 14 session of Broadband Breakfast for a roundtable discussion on the future of the 12 GHz band.
