WASHINGTON, January 27, 2020 – The FCC on Monday named four companies— Google, Sony, CommScope, and Federated Wireless— as Spectrum Access System administrators, the final step toward full commercial deployment of the 3.5 GigaHertz (GHz) band of wireless frequencies.

The Federal Communications Commission framed the authorization as part of a larger effort to push “to get next-generation wireless services deployed in the 3.5 GHz band as quickly and efficiently as possible” according to a statement by Chairman Ajit Pai. He said that the selection is the “latest step” in achieving the FCC’s priority “to free up mid-band spectrum for advanced wireless services like 5G.” See the Public Notice.

The companies selected as official SAS administrators will play a role analogous to that of an air traffic controller in the 3.5 GHz band. They are responsible for ensuring no harmful interference between the three separate categories of users of this bandwidth: Defense department transmitters, Priority Access Licenses, and wireless internet service providers.

This kind of “spectrum sharing” enables multiple users – a WISP and the Defense Department, for example – to co-exist within the same band.

The FCC said that five companies had passed the laboratory test for commercial deployment to begin initial commercial deployment for real world-testing. Amdocs was the fifth company approved for lab tests but not approved to be a SAS administrator, as of the date of the announcement.

Today, after years of development, full commercial deployment of CBRS shared spectrum is a real thing, not a dream,” said Louis Peraertz, vice president of policy for the Wireless Internet Service Providers Association, one of the groups that has most promoted the spectrum-sharing concept. “The FCC must be commended, too, for shepherding the process along, and seeing the immense promise that the CBRS sharing model can and will bring in our spectrum-constrained world.”

Peraertz said the success of the “CBRS experiment” lent credence to making spectrum-sharing work in other bands, including the C-Band, 5.9 GHz and 6 GHz bands.

Editor’s Note: This story has been updated to reflect that Amdocs had not been approved to be a SAS administrator “as of the date of the announcement.” A spokesman for Amdocs contacted Broadband Breakfast to say that the company is still working towards full approval from the FCC to be a commercial administrator, and said that the process will be completed in February.

Dave Wright: Shared Relocation Fund Will Make More of Finite Spectrum Resource

‘Wireless connectivity is one of the most vital aspects of our digital infrastructure.’

In order to meet the gaps in broadband connectivity that persist throughout the country, we must have a more comprehensive view for the necessity of all available spectrum – whether shared, licensed or unlicensed – understanding that they are complementary and independently important to our nation’s future.

As we figure out how we will meet the needs of an increasingly wireless world, it is critical that we think collaboratively on how we can free up and share spectrum, working closely and cooperatively with the federal agencies responsible for our nation’s spectrum resources, the Federal Communications Commission and the National Telecommunication and Information Administration.

With recent confirmed leadership appointments in the NTIA and FCC, and renewed focus on collaboration and collegiality between these organizations, there is hope for renewed effectiveness in America’s overall management of our spectrum resources.

From a policy perspective, the OnGo Alliance is working to shed light on the incentives that inherently exist around the way spectrum is made available today. For terrestrial uses, there are two long established methods for making spectrum available – via a licensing process including an auction of the frequencies, or via an unlicensed allocation where spectrum is made available on a license-exempt basis.

Licensed bands have given rise to our cellular connectivity, while unlicensed spectrum has enabled innovations like the Wi-Fi and Bluetooth solutions that we know and depend upon today. The near ubiquitous presence of these technologies speaks to the efficacy of these approaches. The US 3.5 GHz Citizens Broadband Radio Service is the first spectrum access framework that combines aspects of licensed (protected access) and unlicensed (opportunistic access) spectrum within a single, dynamically managed access paradigm.

Congress has increasingly been looking to licensed spectrum auctions as a source of revenue to cover the funding requirements for new programs. And Federal users who are occupying spectrum and then make the spectrum available for auction can take advantage of monies made available through the Spectrum Relocation Fund to cover the costs associated with transitioning their systems.

The SRF is in turn funded based the resulting auction revenues. These are examples of the current incentives in the system which are either directly or indirectly tied to auction revenues of licensed spectrum. These incentives inherently bias the policymaking processes toward licensed spectrum, at the expense of unlicensed and/or opportunistic spectrum like we have in the CBRS General Authorized Access tier.

This bias is not helpful in our quest to provide accessible broadband throughout the nation as unlicensed and GAA are key components in most solutions, from Wi-Fi as the “last meter” connection to a fixed broadband network to GAA’s prominent role in rural fixed wireless offerings.

CBRS is an optimal framework for putting mid-band spectrum to intensive uses for a wide variety of uses. In the only two years since CBRS commercial operations were approved by the FCC, over 225,000 CBRS base stations have been installed nationwide.

Collaboration between cloud players, system integrators, radio vendors and operators has reached critical mass, building a vibrant, self-sustaining ecosystem. CBRS has allowed enterprises and rural farms alike the opportunity to install private 4G and 5G networks that are connecting IoT devices – from factory robots to autonomous farm equipment. School districts, airports, military bases and logistics facilities, factories, hospitals, office buildings, and public libraries are only but a few of the limitless facilities where connectivity has been enabled by CBRS spectrum.

Wireless connectivity is one of the most vital aspects of our digital infrastructure, and we must use all of the available resources in order to make broadband as ubiquitous as any other utility. Our policymaking, and the incentives around it, must account for the fact that all types of spectrum are important – whether licensed, unlicensed or shared – and that it is vital to ensure that there are proper allocations of each type to meet the relentless demand. We must work together to make the most of what we have.

Dave Wright played an instrumental role in the formation of the OnGo Alliance (originally known as the CBRS Alliance), collaborating with other founding members to create a robust multi-stakeholder organization focused on the optimization of LTE and 5G services in the CBRS band. He served as the Alliance’s first Secretary from its launch in August 2016 and was elected as the President of the Alliance in February 2018. He advocates for unlicensed, licensed, and dynamic sharing frameworks – recognizing the vital role that all spectrum management regimes play in our increasingly wireless world.

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.

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.
