September 8, 2022 – Open radio access networks allow administrators to utilize software that save energy, said Paul Challoner, vice president of Network Product Solutions for Ericsson, at Fierce Wireless’ Open RAN Summit on Wednesday.

Radio access networks connect personal devices – such as phones and computers – to core networks through radio waves. Open RANs’ components, unlike those of traditional RANs, are “interoperable” – a single network can function with pieces made by different manufacturers.

A crucial part of an Open RAN is the RAN Intelligent Control, a software component which enables users to obtain and run native as well as third-party software.

For instance, to eliminate energy waste during periods of light traffic, these sophisticated controls employ artificial intelligence software to direct signals to designated base stations only . This allows other base stations to hibernate. Traditional RANs lack the software capacity of O-RANs and therefore must run all base stations at all times.

Energy initiatives across telecom industry

Elsewhere in the telecom industry, broadband players are pushing for energy-efficient networks as well. Federal Communications Commission Commissioner Geoffrey Starks regularly calls for sustainable, net-zero carbon emissions. “We must continue to find ways to do more while using less,” he said in June.

Additionally, the Fiber Broadband Association recently released a report that found that fiber to the home technology creates less CO2 than either DSL or cable broadband. What’s more, the report found that since FTTH users are disproportionately likely to work from home, FTTH also results in less commute-driven CO2 emissions.

O-RAN as a 5G player

Many believe that open RAN technology will play a substantial role in creating an alternative to proprietary telecommunications equipment. As concerns mount about Chinese telecom manufacturer Huawei – including its connections to the Chinese Communist Party –O-RAN has emerged as a viable alternative to provide 5G coverage.

To safeguard O-RAN networks, networks must employ a bottom-to-top approach to cybersecurity, said Douglas Gardner, chief technologist for the Analog Devices’ CTO Office Security Center of Excellence, at Wednesday’s Open RAN Summit. Gardner argued that every part of the network – down to the chip level – must be constructed with potential cyberthreats in mind.

Ultimately, Gardner believes that expensive up-front investments in cybersecurity prevent far more expensive breaches down the road: “Good security costs vendors money. Get over it.”

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.”

CES 2023: 5G Will Drive Safer Transportation

More comprehensive data-sharing is made possible by the reduced latency of 5G, CES hears.

LAS VEGAS, January 5, 2023 – Panelists at the Consumer Electronics Show 2023 on Thursday touted the potential for 5G to make transportation safer by enabling information sharing between vehicles and with infrastructure.

5G is expected to expand connectivity by attaching small cell connectivity equipment on various city infrastructure, including traffic lights and bus shelters. 

More comprehensive data-sharing is made possible by the reduced latency of 5G, said Aruna Anand, president and CEO of Continental Automotive Systems Inc., referring to connectivity communications times. Anand argued that making relevant information available to multiple vehicles is key to improving safety.

“We give more information about the surroundings of the vehicle to the car to enable [it] to make better decisions,” Anand said.

Durga Malladi, senior vice president and general manager for cellular modems and infrastructure at chip maker Qualcomm, described a 5G-enabled “true ubiquitous data space solution” in which vehicles and smart infrastructure – e.g., traffic lights and stop signs – communicate with one another.

Asked for predictions, Malladi forecasted an increased “blend” of communications and artificial intelligence technologies. Anand said 6G is expected to emerge by 2028 and make its way to vehicle technology by 2031.

Both realized and predicted innovations in 5G-enabled technologies have driven calls for expanded spectrum access, from private and public sectors alike. The Federal Communications Commission and the National Telecommunications and Information Administration, the respective overseers of non-federally and federally-used spectrum, in August agreed to an updated memorandum of understanding on spectrum management

Although relatively new, this agreement has already been touted by officials.

The FCC, whose spectrum auction authority Congress extended in December, made several moves last year to expand spectrum access.

FCC Permit ‘Shot Clocks’ Provides ‘Predictability’ to Wireless Infrastructure Builds: T-Mobile

Shot clocks are important to industry players, argued T-Mobile’s Tim Halinski.

WASHINGTON, November 8, 2022 – Panelists on a Federal Communications Bar Association web panel discussed Monday whether benefits of the Federal Communications Commission’s “shot clocks,” which limit how long states and local governments can review wireless infrastructure applications, outweigh the increased pressures they place on state and local governments.

A shot clock’s deadline puts pressure on city officials’ negotiations with providers over the terms of infrastructure projects, said Nancy Werner, partner at Bradley Werner, LLC, a telecommunications legal and consulting firm. They also “put a lot of pressure on local governments…to make sure (they) have a reason to deny” a provider’s application if an agreement cannot be readily reached, Werner added.

Tim Halinski, corporate counsel for T-Mobile, argued Monday that shot clocks are important to industry players, although he acknowledged the validity of Werner’s concerns. T-Mobile and other providers benefit from expeditious permitting processes, as they look to accelerate the build out of 5G wireless technology.

“There’s no one size fits all,” Halinski said, “But it’s at least the starting point and provides that predictability in deployment that we need.”

The comments come as the FCC fields comments on new standards that would streamline the division of costs between third party attachers and pole owners. Critics say the financial and time delay burden in getting access to these poles have slowed and will slow the expansion of broadband in the country.

In 2018, the FCC instituted shortened shot clocks for small wireless infrastructure projects: “60 days for review of an application for collocation…using a preexisting structure and 90 days for review of an application for attachment…using a new structure.” The commission said the new, limited timeframes would facilitate the deployment of wireless infrastructure.

The FCC’s revised shot clocks for small wireless deployments was but one portion of the agency’s so-called “Small Cell Order” of 2018, which aimed to promote the expansion of 5G. To accomplish this goal, however, the order sought to eliminate regulatory roadblocks by limiting state and local governments’ authorities over wireless infrastructure permitting and their own rights of way. This tactic drew criticisms from many experts and local officials.

Nonetheless, in August 2020, the United States Ninth Circuit Court of Appeals largely upheld the order in City of Portland v. United States.

“(The Ninth Circuit’s) decision is a massive victory for U.S. leadership in 5G, our nation’s economy and American consumers,” said then–FCC Chairman Ajit Pai shortly after the ruling. “The court rightly affirmed the FCC’s efforts to ensure that infrastructure deployment critical to 5G…is not impeded by exorbitant fees imposed by state and local governments.”
