Olivier Ferveur: The Buzz Over 5G Shows That New Fiber Networks Also Need a Global Standard

Published

The author of this Expert Opinion is Dr. Olivier Ferveur, senior network architect at Post Luxembourg

LUXEMBOURG, EUROPEAN UNION – On October 16, Post Luxembourg launched its commercial 5G wireless network, when the first cell sites were activated in the city of Luxembourg and other pilot zones using the 700 MegaHertz and 3.6 GigaHertz spectrum auctioned by city-state earlier this year.

As a senior architect of network access at Post Luxembourg, a state-backed telecommunications company in this small and rich country in the heart of the European Union, I’m pleased to offer my vision of the role that fiber technologies play on their own, and also in advancing 5G mobile development.

Post Luxembourg’s lunch event has been considered as major news item by the local media. For the first time in this post-COVID world, a subject besides the pandemic has in Luxembourg created discussion, enthusiasm, and perhaps a little bit of fear.

Post Luxembourg’s 5G coverage will be steadily extended during 2021 before the footprint is gradually expanded to cover the whole country, providing a “network of the future” that includes advanced applications like cloud gaming.

In fact, for the first time my grandmother asked me questions about my job in the field of broadband. But what and why is all of this happening?

Why is there so much dynamism surrounding 5G wireless technology? Indeed, the technology I am in charge of, XGS-PON, does not appear much in the media but only in a  few specialist press articles. (The term “XGS-PON” refers to 10 Gigabit per second (Gbps) symmetrical fiber using passive optical networks.)

Is this a sign of the end of the fixed broadband network that some people might begin to imagine? Not at all, in my opinion.

5G is not really a technology, but a global concept

To understand this difference in status we must identify that 5G is not really a technology. It is a global concept using multiple technologies that offers many uses for consumers and for enterprises. So what does this mean for fixed networks?

This way of presenting the bundle of technology and use cases is very powerful: It identifies the trends for the public, brings politics inside the discussion and gives broadband operators a perspectives of technology evolution. And for providers of equipment and solutions, this framework leads to research and development that both identifies future problems and gives a global new perspective to all industries.

Yet over the past decade, the so-called fixed network has been increasing bandwidth everywhere. This came through installing fiber technology or by improving existing technology like Vplus, a form of VDSL (which stands for “very high speed Digital Subscriber Line) or G.fast, another DSL technology with performance technology between 100 Megabit per second and 1 Gbps. All these technologies have bringing fiber closer to the consumers in common.

In parallel, network technologies that facilitate installation and maintenance have emerged. These include network function virtualization and software defined networks. But there has been no flashy and global “standard” like 5G that seems relevant and understandable for the public and for business enterprises. Why this difference between the fixed and mobile worlds?

The convention view about geography-specific fixed fiber networks

In fact, the fixed environment has a major difference with the mobile world: Fixed networks have a heavy dependency with massive investment in infrastructure.

Every fiber, copper or coaxial cable which is put in the ground is expected to last at least for 20 years. Because of this long-term investment, each country has a different status and doesn’t necessarily follow the same trend.

In Europe, for example, France has more deeply invested in fiber networks has Germany. Why? It’s because Germany has in the past installed lots of coax cables inside cities. Therefore, fiber investment has not been seen as relevant and necessary there.

In addition, the topographies and the population repartition highly impact the choice of one technology from another.

In fact, we now need a global standard for fiber network deployment

This means that, according to the conventional view, taking a global perspective is nearly impossible in the arena of fixed, fiber-based deployment.

But here’s where I disagree. On the contrary, I believe it is possible to have a global view in favor of fixed, fiber networks. It starts by recognizing how mandatory internet use has become. In one year, the internet use has changed as never in the past, and largely because of the pandemic.

We can speak about the number of devices inside houses, the increase of bandwidth for applications like the increase of 4k or 8k for videos. But in reality, the revolution is not yet here at this point. The true revolution comes for the high interactivity request from consumers.

Today, games, video conference services, enterprise VPN and other applications require a high availability, a disponibility of bandwidth every time, and good latency also. And these are just the requirements from actual and existing applications!

The development of new applications are basically blocked by the limitations in network capability. We need to unlock the network to offer more services.

After 30 years of the creation of the internet, this network is still a “best efforts” network. In other words, we are not able to manage complex apps with high requirements yet.

If we want to technically solve this issue, we need more interactions between open systems interconnections layers and that it is only possible with an overview of all fiber-based systems.

The creation of the F5G standard for fixed or fiber 5G

These observations are some of the reasons that my company, along with other actors inside the European Telecommunications Standards Institute, are participating in the creation of the F5G group, for “fixed” 5G.

This group has the ambition to explore new technologies. F5G want to define use cases based on one principle: Fiber everywhere and in everything. The group not only focuses on residential markets, but also looks at enterprises and vertical industries.

After a definition of the relevant use cases, the F5G group wants to highlight relevant technologies and analyze the gap between them. Collaboration between all standards organizations will become a key point to create a dynamic and reliable environment for the sector and the public.

This initiative has just begin. The whitepaper is already accessible. Additional definitions will come in the current months. Don’t be shy, but join us. This initiative will be successful if a large panel of actors participate to the basement of the next generation of fixed network.

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.

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.

Noah Tulsky: Shared Infrastructure Can Make 5G Work For Cities

Cities should prioritize competitive processes to select an open access neutral host infrastructure provider.

Published

The author of this Expert Opinion is Noah Tulsky, partner at Sidewalk Infrastructure Partners.

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.
