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.
5G Will Help Enhance Environment Protection and Sustainability, Conference Hears
The technology has already been used by companies to monitor and make more efficient systems to reduce emissions.
WASHINGTON, June 28, 2022 – Because of its facilitation of real-time monitoring and more efficient use of systems, 5G technology will help tackle climate change and beef up environmental sustainability, an Information Technology and Innovation Foundation event heard Tuesday.
5G technology’s ubiquitous connectivity and lower latency enables climate technology that decarbonizes manufacturing plants, enables rainforest monitoring, and limits greenhouse gas emissions from transportation.
5G also enables real-time traffic control and monitoring that can help minimize carbon footprint, said John Hunter from T-Mobile, which has a large 5G network thanks in part to its merger with Sprint.
Finnish 5G equipment supplier Nokia has invested in smart manufacturing relying on the speed of 5G in its plants, which it said has resulted in a 10 to 20 percent carbon dioxide reduction and a 30 percent productivity improvement with 50 percent reduction in product defects.
Non-profit tech startup Rainforest Connection has used 5G technology to implant sensitive microphones into endangered rainforests in over 22 countries around the world. These microphones pick up on sounds in the forest and transmit them in real time to personnel on the ground.
These highly sensitive machines are camouflaged in trees and can pick up sounds of gunfire from poaching and chainsaws from illegal logging activity from miles away. The technology has proven to be significant in rainforest conservation and will enable researchers and scientists to find innovative solutions to help endangered species as they study the audio.
“By being able to integrate technologies such as 5G, we can accelerate that process… to achieve the mission [of mitigating climate change effects] sooner than we expected,” said Rainforest Connection CEO Bourhan Yassin.
Tech-Backed Infrastructure Firm Says Private Financing Needed for Shared 5G Facilities
Sidewalk Infrastructure Partners representative says investors must step in as large carriers are burdened by high costs of 5G rollout.
HOUSTON, May 3, 2022 – A representative of an infrastructure firm affiliated with Google’s parent company Alphabet on Monday emphasized the need for private financing in funding open access networks for 5G expansion.
Noah Tulsky, partner at Sidewalk Infrastructure Partners, participated in a panel on private financing of broadband infrastructure projects as part of Broadband Breakfast’s Digital Infrastructure Investment during the Broadband Communities annual summit here.
Sidewalk Infrastructure Partners is an independent company. Alphabet is one of many investors in SIP, alongside Ontario Teachers’ Pension Plan and StepStone Group.
Tulsky stated that at the present, private investment into shared broadband infrastructure networks is particularly necessary in large part because it is capital intensive for large cellular carriers to expand their rollout of 5G networks.
The market climate of the moment makes it difficult to charge cellular customers higher data rates for 5G implementation as consumers are largely unwilling to pay such fees.
Broadband Breakfast’s event also focused heavily on ideal strategies for fiber builds with additional input from advisory firm Pinpoint Capital Advisors’ managing director Andrew Semenak, internet service provider Next Level Networks’ CEO David Barron and Chief Technology Officer Darrell Gentry, and ISP Stealth Communications’ CEO Shrihari Pandit as well as its Business Development Director Joe Plotkin.
Pandit summed up the central question on discussion, stating “Will throwing more money at broadband help to solve key issues like closing the digital divide and making broadband access more affordable for millions?”
Tulsky has written previously in Broadband Breakfast on the symbiotic relationship fiber has with wireless, stating that “wireless broadband can complement fiber technology, which drive down consumer costs and help close the digital divide.”
He stated Monday that funding from Congress’ bipartisan infrastructure bill is likely the best way to build conduit and predicted that in less wealthy, low-density areas conduit will be funded by the government as opposed to private investors, while small and medium fiber companies will be consolidated into larger companies that focus on city-based fiber deployments.
Information about the presentations made during the “Private Financing” panel are available at the Digital Infrastructure Investment page.

Noah Tulsky: Shared Infrastructure Can Make 5G Work For Cities
Cities should prioritize competitive processes to select an open access neutral host infrastructure provider.
Wireless data throughput is expected to increase nearly fivefold over the next four years, a surge driven by overall demand for data and enabled by new chipset technology and increased spectrum allocation.
Traditionally wired internet service providers like Comcast and Charter are investing in mobile connectivity, alongside incumbent mobile network operators. Meanwhile, mobile network operators are amortizing their spectrum investments to compete in the fixed broadband market wirelessly.
A quiet but critical race to deploy wireless networks throughout the country is well underway.
For cities and towns, this rapid growth can represent both a blessing and a curse
More demand for fixed and mobile wireless services means more infrastructure in the form of radios close to end users with annual small cell deployments in cities expected to grow at a roughly 25% compound annual rate through 2026.
Uncoordinated growth can cause headaches and have lasting local and national implications for digital equity, urban landscapes and economic growth.
At the same time, cities that harness the wireless revolution can propel themselves into the future.
Wireless broadband can complement fiber technology, which can drive down consumer costs and help close the digital divide.
And 5G mobile connectivity itself is quickly becoming a necessity. Communities without 5G will be cut off from coming technologies that can save lives and spur economic growth, including autonomous vehicles to serve transit deserts, drone-based maintenance of essential infrastructure and distributed renewable energy.
The deployment of 5G must be carefully managed
Not all 5G build-outs are created equal.
If providers build discrete, separate networks, cities can become overwhelmed by permitting requests to mount radios on light poles and street infrastructure.
If three different companies latch their technology onto the same telephone pole, city infrastructure will end up cluttered, and city residents will be understandably frustrated.
These promising technologies might roll out slowly as city departments work through 5G deployment permitting backlogs.
Worse still, service providers might end up building only in the wealthiest areas—where they can most easily recover their investment. Thus, communities and even whole towns at the margins may be left out.
Policymakers have an opportunity to leverage their infrastructure and ensure that networks are built to be compatible with their goals. State and local officials can use their clout to deliver real and lasting value to as many residents as possible.
Seek out neutral hosts through public-private partnerships
Cities should prioritize competitive processes to select an open access neutral host infrastructure provider that can work with multiple carriers to co-locate on shared infrastructure.
A neutral host can marshal private investment to accelerate network builds and organize the service providers on behalf of the city — all while keeping the process competitive.
This type of public-private partnership has a multiplier effect: Private capital can be united with any public broadband funding and directed toward municipal priorities.
In this model, cities also retain control. Leaders can promote equitable build-outs, ensure that neutral hosts commit to aesthetically consistent and minimally invasive infrastructure, and even earn back a portion of the rent that neutral hosts charge from service providers.
At Sidewalk Infrastructure Partners, where I work, we believe that the best type of neutral host for a city is one that allows multiple operators to share more than just the passive pole infrastructure, and by doing so reduce the visual clutter of the deployment.
For this reason SIP established its innovation platform CoFi and acquired Dense Air Networks, which uses software-defined networking techniques to share radios among multiple MNO tenants, significantly reducing their rental costs and allowing MNOs to deliver quality service economically in areas that would otherwise be underserved.
Coordinate fiber and wireless builds to put federal funding to highest and best use
Cities can now access unprecedented federal funding to fast-track connectivity.
In the recent infrastructure bill, the federal government allocated $65 billion for broadband expansion, in addition to the $10 billion made available through the American Rescue Plan.
These are huge sums, and as with all government funding, they can be used wisely or poorly.
Much of this funding will go toward building fiber and, if done correctly, cities and their private fiber partners can leverage these dollars to ensure that fiber network plans anticipate and enable wireless footprints as well.
Close consultation with wireless neutral hosts, MNOs, and ISPs can help cities get the most bang for their federal buck.
Cities can also avoid the faulty ideas of the past, such as one-time public WiFi builds. These have largely become cost centers, and they rarely deliver quality connections or cover a meaningful geographic footprint.
Cities can instead allocate funding toward financially sustainable projects, which align incentives and help build networks that can last beyond the limits of federal funding.
The 5G rollout offers an opportunity for cities to correct past mistakes — and bring millions of people online and into the digital economy.
With innovation in public-private partnership models and technology, cities can, and should, harness the secular growth in wireless broadband to their advantage.
