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.

Leo Matysine: The Impact of C-Band on Advancements in Mobile and Fixed Broadband

As technology is more advanced and connected to everything, the need for higher capacity networks will continue to grow exponentially.

When consumers think of 5G, often their minds automatically think mobile connectivity. The official C-Band launch this past January brought the idea of increased spectrum connectivity into the limelight. While this had been something anticipated by the telecommunications industry for years, finally seeing it come to fruition allowed the mainstream media to become invested in the benefits this 5G spectrum could offer.

When 5G was first introduced five years ago, it caught the attention of many who soon learned the challenge in speedy implementation due to strict infrastructure requirements. The introduction of C-Band provides a solution, enabling 5G upgrades while simultaneously addressing the coverage and capacity needs.

This heightened implementation will allow users to start seeing improvements across the board, but not just in the form of mobile connection. Outside of the benefits for mobile carriers, the advancements C-Band provides will enter in a new era for fixed broadband access especially in rural communities.

The need for fixed broadband was magnified during the pandemic as users need for internet access from home drastically increased. This exposed the digital divide rural communities are facing, causing it to gain traction with the White House. As a result, a new infrastructure bill aimed at improving the underlying network infrastructures was developed as fiber-to-the-home and fiber-to-the-premise in rural settings have proven to be too expensive and impractical for wide implementation.

C-Band provides an alternative option allowing for wireless fixed broadband access through antennas. The mid-band frequency spectrum (1GHz to 6GHz) can provide rural users, both businesses and households, with options in providers and services they’ve been unable to experience previously.

C-Band also allows for higher speed and capacity

On top of the fixed broadband perspective where C-Band frequency spectrums are enabling rural connectivity, it allows for higher speed and capacity. The spectrums being utilized in the past while generating mobile coverage, had disadvantages in capacity and experience.

The mmWave spectrum (24GHz +) can transmit data at hyper speeds but only from limited distances, requiring line-of-site installations, whereas sub-1GHz offers the opposite. The mid-band spectrum C-Band falls under acts as a perfect balance, transmitting data at high speeds and capacities while providing the coverage needed to cover vast areas. Deployed with lens antenna technology, the additional capacity can be enabled with fewer antenna locations as compared to other antenna types, leading to financial advantages.

From a more localized vantage point, C-Band is now being integrated into marquee venues and stadiums. Within these smaller spaces, improved bandwidth and superior performance is essential given the concentrated number of users seeking connection and the inherent need for more content sharing. In order to support the mobile experience fans now expect from these venues, carriers and venue owners have turned to C-Band deployments.

Deployed atop the 4G/LTE foundation, the C-Band antenna builds off this functionality while adding the increased speed and capacity accustomed to the mid-band spectrum. Several venues will see increased results with these implementations allowing fans to experience a more reliable and overall better experience at their game days or concerts in the upcoming months.

Looking ahead, these milestones only mark the beginning of where C-Band implementation will take the telecommunications industry. As technology continues to become more advanced and connected to everyone and everything, the need for higher capacity networks will continue to grow exponentially.

FCC Chairwoman Jessica Rosenworcel Emphasizes 100 Percent Broadband Adoption

‘It’s about making sure wireless connections are available in 100 percent of rural America,’ said the chairwoman.

PARK CITY, Utah, June 28, 2022 – The Federal Communications Commission is making progress towards bringing “affordable, reliable, high-speed broadband to 100 percent of the country,” Chairwoman Jessica Rosenworcel said at the Rural Wireless Infrastructure Summit here on Tuesday.

Rosenworcel pointed to the $65 billion Infrastructure Investment and Jobs Act now being deployed across the country, with a particular focus on unconnected rural and tribal areas.

Although the Commerce Department’s National Telecommunications and Information Administration will take the lead with these funds, the FCC’s new broadband coverage maps will be important in implementing state digital equity plans.

In her remarks, Rosenworcel also discussed how the upcoming 2.5 GigaHertz spectrum auction will involve licensing spectrum primarily to rural areas.

At the July FCC open meeting, said Rosenworcel, the agency is scheduled to establish a new program to help enhance wireless competition. It is called the Enhanced Competition Incentive Program.

The program aims to build incentives for existing carriers to build opportunities for smaller carriers and tribal nations through leasing or partitioning spectrum. Existing carriers will be rewarded with longer license terms, extensions on build-out obligations, and more flexibility in construction requirements.

“It’s about making sure wireless connections are available in 100 percent of rural America,” she said.

She also indicated her commitment to work with Congress to fund the FCC’s “rip and replace” program to reimburse many rural operators’ transitions from Chinese-manufactured telecommunications equipment. She also touted the role that open radio access networks can plan in more secure telecommunications infrastructure.

In other news at the conference, FCC Commissioner Brendan Carr addressed the role of funding broadband operations in rural America, the challenges of workforce training, and ensuring that rural carriers have access to high-cost universal service support.

In a session moderated by AmeriCrew CEO Kelley Dunne, panelists from the U.S. Labor Department, the Wireless Infrastructure Association and Texas A&M Extension Education Services addressed the need to offer a vocational career path for individuals for whom a four-year degree may not be the right choice. AmeriCrew helps U.S. military veterans obtain careers in building fiber, wireless and electric vehicle charging infrastructure.

WASHINGTON, June 27, 2022 – Experts said at a WiFiForward event last week that there should be more carve-outs for unlicensed spectrum to tackle growing demand for connections and relieve congestion on existing frequencies.

Unlicensed spectrum is a set of frequencies that are not restricted to specific entities and may be used by nearly any device. Wi-Fi devices are most commonly found on unlicensed spectrum frequencies.

“We need a lot more [spectrum],” said Alan Inouye from the American Library Association at the event on June 21. New Wi-Fi devices and a growing number of consumers is driving up the demand for unlicensed spectrum, she said.

Kathleen Burke from internet advocacy group Public Knowledge added that, “[Unlicensed Spectrum] plays a critical role in allowing us to have innovative technology that advances our telecommunications opportunities while at the same time providing affordable opportunities to connect.”

Because spectrum is a finite resource, Burke suggested exploring using the 7 Ghz band to expand the spectrum frequencies.

“Do inventory,” said Burke, “and find out what the next bands are based on actual data about what is occupying the current bands and what is available out there today.”

Deb Collier from Citizens Against Government Waste suggested that the Federal Communication Commission lengthen its auction authority to auction out specific spectrum frequencies and provide more space in bands for unlicensed use.
