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.
More Experts Weigh In On Possibility 12 GHz Band Can Be Shared with 5G Services
More experts weight in on the debate about whether the 12 GHz band can coexist with 5G operations.
WASHINGTON, November 9, 2021 – Experts at the New America Open Technology Institute last week suggested that the 12 Gigahertz band can be shared with 5G wireless services and argued that the big-name proponent that says it can’t has allegedly not produced evidence saying otherwise.
The Federal Communications Commission, studying the sharing possibility, has fielded comments from Elon Musk’s SpaceX, which has argued that the 12 GHz band used by satellite services, cannot be shared with 5G wireless providers because of interference problems. On the other hand, providers like RS Access have argued that it can, using a technical study from RKF Engineering to demonstrate as such.
At a New America Open Technology Institute event on November 2, Kathleen Burke, policy counsel at internet advocacy group Public Knowledge, alleged SpaceX hasn’t submitted any studies showing it’s not possible to share spectrum.
Burke said SpaceX has no engineering analysis supporting its claim that the band could not be shared. “Incumbents are not open to sharing spectrum” she said, alleging a strong desire for SpaceX to win exclusive use licenses for its satellite venture.
“The evidence demonstrates it is possible to share this band,” she added.
Nicol Turner-Lee, director of the Center for Technology Innovation at the Brookings Institution, said that it’s worth looking at innovations in satellite. “When we come up with a solution for the digital divide, shared spectrum use [of the 12GHz band] has always been on the palate,” she said.
“The question is, can we get along when there’s so many people that are disconnected,” she added. “This may not be picking winners and losers and more about getting everyone on board…no one should hog the spectrum if it’s at the expense of communities that need it most.”
Mid-band crucial for 5G
Michael Calabrese, director of the Wireless Future Project at New America’s Open Technology Institute, said that the 500 megahertz of mid-band spectrum on the 12GHz band offers more speed and potential than any other mid-band spectrum being considered by the FCC. Using the 12Ghz band for 5G and authorizing the band for open shared access could “promote more competition, enhance the benefits of next-generation Wi-Fi, and help address the digital divide,” he said.
The RKF engineering study concluded that Starlink’s SpaceX low-earth orbit satellite terminals can reject 5G signals; technology used by mobile wireless networks will direct energy toward handsets, not satellite terminals; and 5G networks will largely be used in higher population areas while Starlink will target mostly rural areas.
House Democrats Introduce Bill to Free Up Mid-Band Spectrum for Auction, Flexible Use
The bill would ensure adequate mid-band spectrum is available for commercial use to expand broadband availability.
WASHINGTON, September 30, 2021 – Reps. Mike Doyle, D-Pennsylvania, and Doris Matsui, D-California, have introduced a bill that would free up new airwaves for wireless broadband use by the public, which the representatives claim would mean faster speeds and more responsive networks.
The Spectrum Innovation Act, unveiled Wednesday and referred to the House Committee on Energy and Commerce on which Doyle is the chairman, will “make available additional frequencies in the 3.1-3.45 GHz band for non-Federal use, shared Federal and non-Federal use, or a combination thereof, and for other purposes.”
The bill comes after Congressman Doyle told Broadband Breakfast last month that spectrum provisions in the Senate-passed infrastructure bill – which is slated to be voted on in the House on Thursday – deviated from the “traditional process” and that he planned to “look at that.”
Among the spectrum rules outlined in the infrastructure bill is the ability of federal officials to seek out spectrum frequencies for federal use, and to shovel money from the Spectrum Relocation Fund toward to the Defense Department for the “purpose of research and development, engineering studies, economic analysis, activities with respect to systems, or other planning activities.”
The affected spectrum in this case would be the 3.1 to 3.45 GigaHertz (GHz) band, a key mid-band series of radio frequencies that includes some federal users, that is the subject of this new bill.
“In addition to up to 200 megahertz of spectrum auctioned for mobile broadband, this bill will help usher in new, innovative wireless uses through opportunistic and other flexible spectrum uses,” Congressman Doyle said.
“For the United States to remain the pacesetter in wireless broadband, we must continue to ensure innovators have a reliable spectrum pipeline,” said congresswoman Matsui in a press release Wednesday.
“We stand at a pivotal moment in the development and deployment of next generation networks; the Spectrum Innovation Act will unleash the economic potential of this valuable mid-band spectrum and give us the tools necessary to meet the communications challenges of tomorrow,” she added.
The bill would require that an investigation be launched into even more frequencies within the bandwidth that could potentially be freed up and sold at auction.
A number of industry associations and public advocacy groups praised the bill.
“The Spectrum Innovation Act of 2021 will greatly benefit consumers by making a very large band of prime spectrum available to help fuel the world’s most robust 5G wireless ecosystem,” said Public Knowledge and the Open Technology Institute at New America in a joint statement.
“We commend Chairman Doyle and Representative Matsui for taking a holistic approach that recognizes the value of making spectrum available both by auction and through shared use by smaller broadband providers, schools, critical infrastructure and literally thousands of individual enterprises on a local basis. This is the policy framework for mid-band spectrum that is most likely to spur 5G competition and innovation, while also ensuring that critical military radar systems can continue to use the band without undue risk of harmful interference.”
The NCTA — Internet and Television Association and the Cellular Telecommunication and Internet Association also came out to voice support for the bill.
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.”
