September 15, 2020 – Advocates for the much-promoted 5G wireless standard last week explained that the COVID-19 pandemic has accelerated the timetable for deployment.

“COVID-19 has just made the future sooner,” said Joe Reele, vice president of Schneider Electric. “Private 5G networks are going to be incredibly impactful.”

“There is more demand for infrastructure,” added Ryan Lepene, co-president of Pepper Tree Capital. And Leticia Latino van-Splunteren, CEO of Neptuno USA, Inc. pointed out that many businesses have changed their models accordingly to meet this demand.

Each were speaking at the 2020 conference of NEDAS, an industry-led nonpartisan association enabling communications infrastructure.

Some companies have instituted paired down versions of 5G networks called 5G non-standalone networks in preparation for the full rollout. These networks “combine an existing LTE channel for 5G signaling” with other newer developments in 56 explained Art King, director of enterprise services at Corning.

“5G is the first ‘G’ that is not just a faster radio network,” said King.

He explained that 5G builds on four technology building blocks that combine to meet eight technological goals and three user benefits.

The first four chief goals of 5G are to improve, by a factor of 10, the user experienced data rate, area traffic capacity, connection density, and latency. The other four goals have varying rates of improvement, with spectrum efficiency being three times more efficient than LTE, peak data rate improving by up to 20 times, network energy efficiency improving 100 times, and mobility improving from 350 to 500 km/hr.

Building blocks for 5G wireless technologies

Speakers at the NEDAS conference discussed the key building blocks for 5G technologies. They are the so-called 5G-NR (where “NR” stands for “new radio”), 5G Radio Access Network/5G standalone, ultra-reliable and low latency communications, and network slicing.

The 5G-NR standard is a descendant of the LTE air interface and has increased the wideband signal from 20 megahertz to 400 megahertz.

To do this, “we’ve had to open up frequency ranges in what’s called the millimeter wave to actually support that wideband signal,” said King.

The 3 GigaHertz (GHz) to 6 GHz range of the spectrum is “where the prime spectrum is,” said Shirish Nagaraj, chief technologist at Corning Optical Communications, “That’s what’s getting talked about in terms of CBRS, and going forward in C-Band as well.”

Importance of Radio Access Networks, dynamic spectrum sharing, and ultra-low latency

In 5G RAN/5G standalone all the data signals occur between the phone and the tower. Because the United States is so large, we can’t deploy this yet, “so we have to maintain a lot of compatibility and leverage the LTE core networks in place,” said King.

Dynamic spectrum sharing is one way of leveraging the LTE networks. While the LTE signals go off constantly and provide “blanket coverage,” Nagaraj explained, the NR signals “fit around” the LTE signals and don’t go off constantly, acting as a supplemental data channel.

The ultra-reliable and low-latency combination monitor refers to a collection of software and hardware techniques that enable high availability, low latency, and “in some cases, bounded jitter for critical application performance needs,” expounded King.

One of the main technologies included in this is yet another buzzword: Massive MIMO, for Multiple Input, Multi Output. After all, with full 5G, different signals transfer through multiple antennas. These signals are decoded by the user’s equipment.

Nagaraj pointed out that this technology “doubles or quadruples the capacity depending on the number of antennas that you’re using.”

Network slicing creates multiple virtual networks on top of a shared physical infrastructure, meaning that having access to a single physical network no longer means access to a single network. This capability is useful in the hospitals where the vast amount of equipment usually requires having multiple networks to ensure that everything runs smoothly.

Through these building blocks, users should experience enhanced mobile broadband (greater bandwidth), greater device density, and lower latency rates.

King urged users that when exploring 5G offers that they consider the underlying building blocks being used to deliver the service.

Google, Reliant On Success of 5G, Says It Wants Government-Funded Test Beds for Open RAN

Company says that the next generation of its products depend on 5G progress.

Alphabet CEO Sundar Pichai

WASHINGTON, October 20, 2021 — Google made its case for regulators to make room for greater public-private collaboration in the wake of 5G and more research into open radio access network technologies.

Speaking at the Federal Communications Bar Association’s “What’s New and Next in Wireless” session on Tuesday, Michael Purdy from Google’s product and policy team emphasized Google’s interest in the emerging 5G landscape, but wants a “collaborative environment” for innovation.

“5G is exciting because of Google’s products depend on 5G,” he said. “[Our] products can’t come to market without it.” Google’s recent product launches include smart-home technologies. Purdy says their products’ benefits are enhanced as 5G is deployed.

Google, like the technology sector at large, is building on the innovation that the “app economy” produced using existing 4G technology and plans to expand their software capabilities with 5G. “The app economy benefited consumers,” Purdy says. “Our lifestyles are going to depend on 5G.” For telehealth, “real time medical advice needs low latency [and] high speeds.”

However, Google hopes for better regulatory conditions during 5G deployment. “We haven’t been as focused on the FCC [for guidance] . . . we want stability to determine spectrum policy.”

Purdy said the company hopes to work collaboratively with government to find solutions for wider 5G deployment. “[We] want to know what position the government takes in creating an open RAN environment.”

The company said it wants government funded-test beds for open RAN, research into development to ensure that “the downside costs are defrayed.” In overcoming these challenges to 5G deployment, Purdy said Google wants the government to foster a “collaborative environment” to develop open RAN. “We don’t want government picking winners and losers in the innovation process” he said.

Purdy added that spectrum sharing between licensed and unlicensed users “can be good for consumers and for industry.”

The Federal Communications Commission has pushed for ways to develop open RAN to minimize network security risk, as the movement has gained significant momentum. FCC Acting Commissioner Jessica Rosenworcel has described open RAN as having “extraordinary potential for our economy and national security.”

Huawei Avoids Network Security Questions, Pushes 5G Innovation

Huawei’s CTO avoided questions about concerns over its network infrastructure security as countries ban its products.

Huawei carrier business CTO Paul Scanlan.

WASHINGTON, October 19, 2021 — Huawei’s chief technology officer did not address questions Monday about the company’s network security practices during a session on how 5G drives economic growth, but said the focus should be on the evolutionary technology instead.

Paul Scanlan, Huawei’s CTO in the carrier business group, focused his presentation at the Economist Impact Innovation@Work conference on the promise of 5G technology and ignored concerns about network safety.

“We can service more customers with 5G” to start bridging the digital divide, he said. The pandemic has given the company an insight into customer behavior to better channel its data traffic needs. “5G performs better for the types of services we use now” he says, such as video streaming and user-generated content.

Scanlan avoided specific questions about his company’s technology and steered the conversation toward providing faster speeds for the health care industry. “Give me some use instances where the company has introduced 5G and helped companies be efficient” asked the moderator, Ludwig Siegele. “I’d like to stick on the health care sector, that’s more topical as you can imagine,” Scanlan responded.

“People are missing [innovation in 5G] because of geopolitical issues around the world,” said Scanlan. “Being able to collect the data and analyze it is where the business benefit lies . . . 5G adoption through the [standardized network] ecosystem is very important and we see this with 5G” for interoperability with other companies and providers.

Huawei’s promotion of their telecommunications products continues as the U.S. maintains national security sanctions against the tech giant. The impact of U.S. sanctions results a drop in sales for the company in 2021. The FCC has also recommended that Huawei’s equipment be listed as “high risk” to U.S. network security. Huawei told the FCC it cannot show the company’s equipment is a threat to U.S. networks.

Huawei’s global head of cybersecurity said this summer that President Joe Biden‘s executive order banning investments in Chinese companies is a “policy misstep” that will not only lose the U.S. a huge market, but will just make the company more self-sufficient.

WASHINGTON, October 15, 2021–Federal Communications Commissioner Brendan Carr on Friday celebrated U.S. progress in 5G wireless investment and urged the completion of the agency’s broadband mapping initiative.

Speaking a the Free State Foundation gala luncheon, Carr argued that the United States has progressed in its 5G investments and is catching up to foreign networks. ”Years ago we imaged the U.S. would be left behind in 5G,” he said.

He touted his and former FCC Chairman Ajit Pai’s efforts to “remove the red tape.” Enabling the private sector has paid off, he said: The U.S. has jumped 20 places on the country internet speed index, signaling the installation of more robust U.S. 5G networks.

Further, the FCC should complete its broadband mapping process and take caution with the federal money allocated toward broadband deployment, he said, adding that he asked the FCC earlier this year to complete its map by fall 2021.

“There’s planning that can take place when the maps are completed” he said, reflecting a desire from the public and private sector for better, more accurate broadband maps.

He also said that federal money allocated toward the FCC’s efforts to bridge the digital divide should be used carefully, and that money to connect unconnected Americas should not be wasted.

Carr celebrated American investment in 5G progress earlier this year, calling U.S. leadership in 5G “one of the greatest success stories in of the past four years.” In that time, the FCC opened up more than six gigahertz of spectrum for 5G services.

Former FCC Commissioner Michael O’Rielly also gave remarks at the event, expressing concern about the federal Made In America policy’s implications on the telecommunications sector.

The Made in America policy refers to President Biden’s push to increase American made content in supply chains. O’Rielly, who left the Commission in December 2020, argued that the policy limits telecommunications companies to the kinds of products that can be made available to consumers.

He also questioned “what it means to be an American manufacturer” because foreign companies are “in essence, being punished by law” for having “investments in the U.S. with U.S. workers as part of a U.S. subsidiary.”

In O’Rielly’s view, the location of the companies headquarters does not impact its national security risk to the U.S.

The remarks by Carr and O’Rielly were at the 15th anniversary celebration for the free-market think tank. Carr said that the foundation has been an “invaluable resource” and has been cited more than 200 times in FCC decisions.
