NEW ORLEANS, May 11, 2023 – Fifth generation mobile networks has enabled fixed wireless technology to be deployed in areas where it wouldn’t have been accepted otherwise, said Jay Brown, CEO of communications infrastructure company Crown Castle at a Connect (X) forum here on Wednesday.

Fixed wireless will never be a true replacement for a wired network, said Brown, but providers have been successful thus far because running 5G on a fixed wireless network brings speeds up to par with wired connections. “The speeds you get on a fixed wireless network [with 5G] are matching that of the wired solution,” he said.

We’ve seen that if given a choice, consumers will choose wireless over a wired connection, Brown continued, speaking at the Wireless Infrastructure Association trade show. Providers have noted an increase in demand for small cell towers that transmit wireless over a high frequency in a small geographic area, he claimed.

For many communities, managing aesthetic is singularly important and this desire fuels the deployment of small cells, he said.

Due to the faster speeds that 5G enables, providers are seeing deployment in areas that would not have accepted it otherwise due to its lower speeds, added Steve Vondran of American Tower, provider of wireless communications infrastructure..

This allows providers to enter previously untapped networks and connect people across rough terrain and in rural areas, he said.

“Fixed wireless is driving incremental returns but this is just the first application [of 5G],” said Brown. Our use cases haven’t evolved to utilize the full capacity of 5G, agreed Vondran.

Spectrum concerns

However, for wireless providers, spectrum allocations are a continuous concern. The Federal Communications Commission’s spectrum auction authority which allows it to auction spectrum for private use expired in March.

Vondran suggested that the government will need to work with the Department of Defense which holds a significant amount of spectrum to make more available privately.

“If the demand drivers are as predicted, we will need more spectrum made available,” said Jeff Stoops, CEO of SBA Communications.

Until more spectrum is released, industry leaders expect that spectrum shortages will lead to great densification of the networks, the process of increasing small cell towers in an area to address growing demand.

Leaders of the FCC urged lawmakers in a letter dated in April to extend the agency’s spectrum authority amid demands for more across the industry.

WASHINGTON, February 2, 2023 – A global approach to funding open radio access networks will improve its success in the United States, say commenters to the National Telecommunications and Information Administration.

The NTIA is seeking comment on how to implement the $1.5 billion appropriated to the Public Wireless Supply Chain Innovation Fund as directed by the CHIPS and Science Act of 2022. The grant program is primarily responsible for supporting the promotion and deployment of open, interoperable, and standards-based radio access networks. 

Radio access networks provide critical technology to connect users to the mobile network over radio waves. O-RAN would create a more open ecosystem of network equipment that would otherwise be reliant on proprietary technology from a handful of companies.  

Global RAN

Commenters to the NTIA argue that in order for O-RAN to be successful, it must be global. The Administration must take a “global approach” when funding projects by awarding money to those companies that are non-U.S.-based, said mobile provider Verizon in its comments.  

To date, new entrants into the RAN market have been the center for O-RAN development, claimed wireless service provider, US Cellular. The company encouraged the NTIA to “invest in proven RAN vendors from allied nations, rather than focusing its efforts on new entrants and smaller players that lack operational expertise and experience.” 

Korean-based Samsung Electrontics added that by allowing trusted entities with a significant U.S. presence to compete for project funding and partner on those projects, the NTIA will support standardizing interoperability “evolution by advancing a diverse global market of trusted suppliers in the U.S.” 

O-RAN must be globally standardized and globally interoperable, Verizon said. Funding from the Public Wireless Innovation Fund will help the RAN ecosystem mature as it desperately needs, it added.  

Research and development

O-RAN continues to lack the maturity that is needed for commercial deployment, agreed US Cellular in its comments. The company indicated that the complexity and costliness of system integration results from there being multiple vendors that would need to integrate but are not ready for full integration. 

Additionally, interoperability with existing RAN infrastructure requires bi-lateral agreements, customized integration, and significant testing prior to deployment, the comment read. The complicated process would result in O-RAN increasing the cost of vendor and infrastructure deployment, claimed US Cellular, directly contrary to the goals of O-RAN. 

Several commenters urged the NTIA to focus funding projects on research and development rather than subsidizing commercial deployments.  

The NTIA is already fully engaged in broadband deployment in unserved and underserved areas through its Broadband Equity, Access and Deployment program, said Verizon. The Innovation Fund will better advance its goals by funding projects that accelerate the solving of remaining O-RAN technical challenges that continue to delay its deployment, it continued. 

US Cellular argued that the NTIA should “spur deployment of additional independent testing and certification lab facilities… where an independent third party can perform end to end testing, conformance, and certification.” 

The Innovation Fund should be used to focus on technology development and solving practical challenges, added wireless trade association, CTIA. Research can focus on interoperability, promotion of equipment that meets O-RAN specifications, and projects that support hardware design and energy efficiency, it said. 

Furthermore, CTIA recommended that the Administration avoid interfering in how providers design their networks to encourage providers to adopt O-RAN in an appropriate manner for their company. Allowing a flexible, risk-based approach to O-RAN deployments will “help ensure network security and stability,” it wrote. 

LAS VEGAS, January 7, 2023 – Commissioner Geoffrey Starks of the Federal Communications Commission spoke at the Consumer Electronics Show Saturday, touting connectivity assistance for individuals who benefit from housing assistance as well as the potential environmental benefits of 5G.

The FCC-administered Affordable Connectivity Program subsidizes monthly internet bills and one-time devices purchases for low-income Americans. Although many groups are eligible – e.g., Medicaid and Supplemental Nutrition Assistance Program enrollees – Starks said his attention is primarily on those who rely on housing support.

“If you are having trouble putting food on your table, you should not have to worry about connectivity as well,” Starks said. “If we are helping you to get housed, we should be able to connect that house,” he added.

Environmental benefits of 5G

In addition to economic benefits, 5G-enabled technologies will offer many environmental benefits, Starks argued. He said the FCC should consider how to “ensure folks do more while using less,” particularly in the spheres of spectral and energy efficiency.

“This is going to take a whole-of-nation (approach),” Starks said. “When you talk to your local folks – mayors – state and other federal partners, making sure that they know smart cities (and) smart grid technology…making sure that we’re all unified on thinking about this is exactly where we need to go to in order to drive down the carbon emissions.”
