Broadband Mapping Coalition Seeks to Bring Openness Back to Internet Data
The coalition will play a crucial role in broadband data as government implements the largest expenditure of broadband funds.

June 17, 2022 – Non-profit organizations and academic researchers seeking to ensure the openness and transparency of broadband data collection efforts have created an organization, the National Broadband Mapping Coalition, seeking to gather resources on data and mapping.
Shepherded by the Marconi Society, this National Broadband Mapping Coalition has filed comments before the Federal Communications Commission and is ramping up its efforts to be a leading voice for open and transparent broadband data.
The group is led by Dustin Loup, of the public interest group Marconi Society. Loup has been actively involved in the internet governance and policy space for years. Together with Measurement Lab (which is led by Lai Yi Ohlsen), a non-profit group that has been collecting broadband speed data since 2008, these two organizations are poised to promote the vital role of open broadband data as the U.S. Commerce Department implements the largest expenditure of federal broadband funds in history.

Why we need open broadband data
In a recent piece on Broadband.Money, Sarah Lai Stirland details the importance of actual speed data in challenging existing Federal Communications Commission broadband data:
- If you click on the census blocks around Newcastle in Broadband Money’s online map, you’ll see that the Federal Communications Commission data shows the blocks as “served” because at least one location has access to internet service of 1000 Mbps symmetrical service. That information is self-reported data from the form 477 that the FCC requires internet service providers to provide.Speed tests from Ookla and the non-profit M-Lab, however, indicate that that census block is, at the very least, “underserved” by the standards established by federal legislation such as the American Rescue Plan Act and the Infrastructure, Investment and Jobs Act. M-Lab says that average internet speeds in the area are 22 Mbps * 5 Mbps and Ookla reports 63 Mbps * 6 Mbps.
Lai Stirland’s profile of Ohlsen and Loup also discusses her skills in computer science and project management, and Loup’s history of involvement in the internet by the Arab Spring.
On a personal level, I’ve been a strong advocate of the importance of public and open broadband data for more than 15 years. See “U.S. broadband infrastructure investments need transparency,” ArsTechnica, February 10, 2009. That op-ed recounts our efforts to obtain FCC Form 477 data in 2006 and 2007, followed by founding BroadbandCensus.com in January 2008 to crowdsource the collection of broadband speed and availability data.
But this was superseded by the National Broadband Map, version 1.0, launched in February 2011. In that first national broadband map, State Broadband Initiatives (like the Partnership for a Connected Illinois) played a primary role in the collection of provider data about broadband availability.
But that national broadband map failed for two reasons:
- Everyone in a census block was considered “covered” if one person in a census block was “covered,” or served with 25 Mbps * 3 Mbps broadband.
- Broadband speeds were self-reported by providers, and there was limited fact-checking, or crowdsourcing, of actual broadband speeds.
Broadband mapping is about to become one of the most central issue in the rollout of the Infrastructure Investment and Jobs Act. Without the crucial check of open and public data, broadband mapping runs the risk of falling victim to the same challenges of the last decade.
Who is the National Broadband Mapping Coalition?
The National Broadband Mapping Coalition lays out the problem, and the solution, extremely well on its web page – which is worth quoting at length:
- U.S. policymakers, advocates, and researchers need access to more comprehensive and reliable data on broadband coverage in order to solve the digital divide. The data currently available is insufficient and often misleading. Through a partnership with leaders who value transparent, peer-reviewed, open data, we’re innovating a new approach to mapping broadband network analytics that will help stakeholders gain data-driven insight into this critical issue.
- The Problem
Millions of U.S. residents live without adequate broadband access. While the FCC collects self-reported broadband coverage data from Internet Service Providers (ISPs), that data is often inaccurate and incomplete, and does not offer a detailed, granular picture of connectivity and affordability gaps. Without more complete data, localities face barriers in making their case for securing state and federal funding that is intended to address these digital divides.We believe transparent measurement standards based on new and existing open-source and openly verifiable methodologies are necessary to provide communities with the tools they need to collect data on connectivity speeds, pricing, and availability.State, local, and U.S. Governments restrict data collection and/or sharing for a variety of reasons, resulting in the inability to provide full transparency. The work of the National Broadband Mapping Coalition is intended to strengthen government broadband initiatives and provide the public with much-needed performance information…. - Coalition
We have convened a national coalition of leaders in digital inclusion, technology, research, and policy. Responding to an increased focus on broadband adoption and measurement at the federal level, as well as the continued failure to consistently and verifiably map existing broadband infrastructure, performance, and value, this coalition aims to establish best practices and enable communities, governments, and individuals to access information they need….
In addition to the Marconi Society and M-Lab, other charter partners of the coalition include Google (which has supported M-Lab since its launch), the Internet Society, the Institute for Local and Self-Reliance, and X-Lab. Read more about its vision and mission.

Priorities for open broadband data research
Rather than creating one more map, the National Broadband Mapping Coalition is beginning to bring a greater clarity around the importance of open and transparent data for broadband.
In its recent filing at the FCC, the coalition discussed the comparability of quality of service metrics, with a particular focus on the basic forms of measurement: download and upload speeds and latency. But they say,
- Speeds and latency are common metrics many people are familiar with, but they are not the only metrics of Internet performance that matter to the quality of service. Jitter, packet loss, and bufferbloat (latency under load) each have a direct impact on actual experience of Internet users. When any of these metrics are performing poorly, it can be especially detrimental to the performance of real-time applications that support activities, such as a telehealth appointment, job interview, virtual classroom participation, or meeting a new grandchild from thousands of miles away. These impacts on the quality of experience can occur regardless of the bandwidth. Additional quality of service metrics such as network uptime and the mean repair time to restore access are important metrics. The Coalition recommends that the Commission takes steps to identify a set of measurable quality of service indicators, including but not limited to those described in these comments.
No one said that broadband mapping was going to be easy. The more rocks that you turn over, the more dirt that you find. But the easiest way to improve and to course-correct is to be scientific. And that starts with open and transparent data.

Robocalls, Rip and Replace, Pole Attachments: More Notes From the FCC Oversight Hearing
Commissioners and House lawmakers discussed key topics at a contentious hearing.

WASHINGTON, December 1, 2023 – All five Federal Communications Commissioners took part in a lengthy and at times contentious House oversight hearing on Thursday.
Commissioners urged Congress to restore the FCC’s authority to action spectrum, which expired in March and left the nation’s airwaves in limbo, and to fund the Affordable Connectivity Program, the low-income internet subsidy set to dry up in April of next year.
GOP lawmakers FCC Republicans also took the chance to slam efforts by the commission’s Democratic majority.
The discussion touched on other issues including robocall prevention, rip and replace funding, and pole attachments.
Robocalls
The commission has been taking action on preventing robocalls this year, kicking off an inquiry into using artificial intelligence to detect fraud, blocking call traffic from 20 providers for lax enforcement policies and issuing hundreds of millions in fines. In August the commission also expanded the STIR/SHAKEN regime – a set of measures to confirm caller identities – to all providers who handle call traffic.
FCC Chairwoman Jessica Rosenworcel asked multiple times for three Congressional actions she said would help the commission crack down on scam calls: a new definition for “autodialer,” the ability to collect fines, and access to Bank Secrecy Act information.
The Supreme Court limited the definition of autodialers in 2021 to devices that store or produce phone numbers with random or sequential number generators. That leaves the scope of the Telephone Consumer Protection Act, which guides the FCC’s authority, “stuck in the nineties,” according to Rosenworcel.
“A lot of scam artists are using technologies no longer covered” by the act, she said. “We can’t go after them.”
On collecting robocall fines, that authority currently rests with the Department of Justice, and Rosenworcel is not the first to tell Congress the agency’s enforcement has been lax. Industry groups at an October Senate hearing cited slow DOJ action as a major reason FCC fines on the issue often go uncollected.
The Bank Secrecy Act requires financial institutions to keep records on certain transactions to help law enforcement agencies track money laundering and other criminal activity. The FCC cannot access information governed by the act, which Rosenworcel said would help the commission go after repeat scammers.
“These scam artists set up one company, we shut them down, they go and set another one up,” she said.
Rip and replace
Commissioners urged Congress to fund the rip and replace program. Congress allocated $1.9 billion to reimburse broadband companies for replacing network equipment from Chinese companies deemed to be national security threats, mainly Huawei and ZTE.
The FCC was tasked with overseeing the program and found in 2022 that another $3 billion would be needed to get the work done. The Biden administration joined a chorus of lawmakers and broadband companies in calling for Congress to fill the gap, but legislation on the issue has yet to be passed.
“We’re providing 40 cents on the dollar to a lot of small and rural carriers,” said Rosenworcel. “They need more funds to get the job done.”
The commission has been granting extensions to providers unable to get the work done on time. In addition to supply chain issues, some small providers cite a lack of funding as the reason they’re unable to replace insecure equipment.
Pole attachments
Commissioners expressed a willingness to shift some of the burden of utility pole replacements off of broadband providers as they attach new equipment.
“If a pole is getting replaced,” Commissioner Brendan Carr said, “there’s probably a role for the FCC to say that the pole owner should bear somewhere north of the cost of $0.”
The commission has authority in 26 states over most pole attachment deals between utility pole owners and telecommunications companies looking to expand their networks. The issue of who pays for poles that need to be replaced to accommodate more communications equipment is contentious, with telecoms arguing utilities force them to pay for replacing already junk poles.
After spending years sifting through thousands of comments, commissioners have apparently been persuaded. Rules up for a vote at the commission’s December meeting would limit the scenarios in which utilities could pass full replacement costs on to attachers.
Broadband funding map
Rosenworcel repeatedly asked lawmakers to work with the commission on ensuring its broadband funding map is kept up to date.
The FCC launched its funding map in May to keep track of the myriad federal broadband subsidy efforts and avoid funding the same areas multiple times. The Department of Agriculture, the FCC, and the Treasury Department each oversee separate broadband funding programs, in addition to the Commerce Department’s upcoming $42.5 billion broadband expansion effort.
The commission has signed memoranda of understanding with those agencies on providing data for the funding map, but Rosenworcel asked the subcommittee for help ensuring the agencies follow through and respond to FCC requests for their funding data.
“If you could help us make sure those other agencies respond to us with data, you’ll see where there are problems, duplication, areas we haven’t reached,” she said.

Connect20 Summit: Data-Driven Approach Needed for Digital Navigation
The NTIA’s Internet Use Survey doesn’t delve deeply enough into why people choose not to adopt broadband.

WASHINGTON, November 20, 2023 – Better data about broadband adoption is necessary to closing the digital divide in the U.S., a broadband expert said during a panel at the Connect20 Summit here.
Speaking on a panel about “The Power of Navigation Services,” the expert, Jessica Dine of the Information Technology and Innovation Foundation, said states lack comprehensive data on why some residents remain offline. This information is essential for digital navigator programs to succeed, she said.
She highlighted the need for standardized national metrics on digital literacy and inclusion, and said that federal surveys – including the Census Bureau’s American Community Survey – provide insights on barriers to technology adoption. But more granular data is required.
She also said that the National Telecommunications and Information Administration’s Internet Use Survey doesn’t delve deeply enough into why people choose not to adopt the internet. For instance, understanding the nuances behind the ‘not interested’ response category could unveil targeted intervention strategies.
In particular, Dine praised Louisiana and Delaware for surveying communities on their connectivity needs, including overlaying socio-economic indicators with broadband deployment data. But she said more work is required to quantify the precise challenges different populations face.
Other panelists at the session, including Michelle Thornton of the State University of New York at Oswego, emphasized the importance of tracking on-the-ground efforts by navigators themselves.
Bringing in her experience from the field of healthcare navigation, Thornton underscored the value of tracking navigator activities and outcomes. She suggested a collaborative model where state-level data collection is supplemented by detailed, community-level insights from digital navigators.
The panel was part of the Connect20 Summit held in Washington and organized by Network On, the National Digital Inclusion Alliance, and Broadband Breakfast.
The session was moderated by Comcast’s Kate Allison, executive director of research and digital equity at Comcast.

House Subcommittee Witnesses Disagree on AI for Broadband Maps
The Communications and Technology Subcommittee held a hearing Tuesday on using AI to enhance communication networks.

WASHINGTON, November 14, 2023 – Experts disagreed on the potential for artificial intelligence to aid broadband mapping efforts at a House hearing on Tuesday.
Courtney Lang, a vice president at tech industry trade group ITI, said AI could be used to improve the quality of current broadband maps.
A machine learning model could do that by using past data to identify buildings that are likely to be accurately marked as having adequate broadband, according to Lang.
“It’s a really interesting use case,” she said.
Broadband mapping is a difficult task. The Federal Communications Commission’s broadband map is on its third version, undergoing revisions as consumers submit challenges to provider-reported broadband coverage data. The Biden administration’s $42.5 billion broadband expansion program requires states to administer a similar ground-truthing process before allocating any of that cash.
But Nicol Turner Lee, director of the Brookings Institution’s Center for Technology Innovation, urged caution.
“We have to be careful that we might not have enough data,” she said.
In rural parts of the country, data can be sparse and low-quality. Both factors would make machine learning ill-suited to the task of flagging potential inaccuracies, according to Lee.
She urged lawmakers to exercise restraint when using AI for “critical government functions,” like the broadband maps used to determine where federal grant money will go.
The witnesses spoke at a House Communications and Technology Subcommittee hearing on using AI to enhance American communication networks.
