FCC Added Just Over 1 Million Net New Locations in Broadband Map Fabric Slated For Spring Release: Chairwoman
Chairwoman Jessica Rosenworcel said the second version of map fabric ‘largely completed.’

WASHINGTON, March 23, 2023 – The head of the Federal Communications Commission said Thursday that the commission added just over one million net new broadband serviceable locations after processing challenges and improving data models in its second round of data collection that ended March 1.
In a mapping update blog post, chairwoman Jessica Rosenworcel noted that the net additions to the map – where fixed broadband could be installed – came after it added 2.96 million new locations and removed 1.92 million locations from the first version of the fabric released in November.
The chairwoman also said the second version of the fabric, which underpins the broadband map, is “largely completed” and is slated for a release later this spring. The map will be used by the National Telecommunications and Information Administration to spread among the states by June 30 the $42.5 billion from its Broadband Equity, Access and Deployment program.
“In the past four months, our mapping team has processed challenges to availability data for over 4 million locations,” Rosenworcel said in the post. “In other words, on average, we are addressing availability challenges to tens of thousands of locations every single day. Every two weeks, our public map is updated to reflect all availability challenges that have been resolved. In other words, the system is working.”
The chairwoman noted that the one-million-location difference suggests that the net adjustment from the last version of less than one percent in the number of serviceable locations “says that, on balance, the November pre-production draft of the National Broadband Map painted a helpful picture of where high-speed Internet service could be available.”
Previously, the chairwoman said challenges that sought corrections to the data corresponded to less than one percent of the total number of locations identified.
Rosenworcel also noted Thursday that important corrections and additions to the data were made, including “data refreshes to more sophisticated tools” that helped remove structures like garages and sheds. The most significant additions were in Alaska, U.S. territories and tribal lands, she said.
The challenge process led to nearly 122,000 new location additions, she noted, but also added that the majority of location adds were due to the updates and dataset model refinements by the agency’s contractor CostQuest.
“While over time we expect future versions of the Fabric to require fewer refinements,” Rosenworcel added, “these ongoing efforts to improve the Fabric outside of the challenge process will continue and will remain an important tool for the improvement of the National Broadband Map.”

Tribes Must Be Ready to Challenge State Broadband Maps: Tribal Ready
Tribes needs to be prepared to approach states on what coverage data is not included in state maps.

WASHINGTON, May 31, 2023 – Tribal governments should gather broadband coverage data for the state mapping process, said Joe Valandra, CEO of newly formed Native American-owned data company Tribal Ready at a Broadband Breakfast Live Online event Wednesday.
Historically, tribal data has been excluded or misinterpreted in broadband maps, he said. The $42.5 billion Broadband Equity Access and Deployment program will be allocated to subgrantees by state governments according to state broadband maps.
Tribal governments need to be prepared to approach the state with a data-driven argument about what coverage data is not included in the state map and what changes need to be made, said Valandra.
In turn, state broadband offices need to listen to tribes, added Megan Beresford, director of broadband programs at grant writing company Learn Design Apply.
The $3-billion Tribal Connectivity Program of the National Telecommunications and Information Administration received over $5 billion in grant requests from its application process last year. BEAD allocations, expected to be announced by the end of June, can play a part in addressing the undersubscription of funds to tribal programs, said E.J. John, senior research analyst at the American Indian Policy Institute.
Other federal programs can also support tribal connectivity, said Beresford. The Affordable Connectivity Program allows eligible low-income households to get a discount on broadband of up to $75 per month on tribal lands.
The NTIA announced in May nine new Tribal Broadband Connectivity Program grants of $500,000 each, bringing the program’s total amount disbursed to $1.77 billion.

South Carolina’s Innovative Broadband Maps Verifies ISPs’ Internet Speeds
South Carolina performs mapping audits to hold ISPs accountable for coverage claims.

WASHINGTON, May 21, 2023 – South Carolina’s innovative state broadband map can accurately identify areas of over-reporting by internet service providers, the director of the state’s broadband office said in a Friday Ask Me Anything! session in the broadband community.
South Carolina processes the same data as does the Federal Communications Commission as it creates its broadband map. However, it also performs audits on the ISPs to ensure they are submitting accurate data. Hence, the state can determine errors in reporting data based on where the ISP’s networks had been deployed previously and where state investments have gone, said Jim Stritzinger, director of the state’s broadband office.
Providers are required to file amended returns with the FCC in the event that South Carolina’s state broadband office flags errors in their reporting information. Errors include misreporting of technology types.
If the reporting errors are not corrected, the state will report the defaulting ISP to the FCC, said Stritzinger, a software engineer with a passion for mapping broadband in the Palmetto state.
A big flaw of the FCC’s maps is that ISPs were able to report advertised speeds, which Stritzinger said were useless.
To enhance the accuracy and reliability of the maps, Stritzinger partnered with broadband data collection company Ookla, and integrated speed test data directly into the mapping system. More than 12 million Ookla speed tests have now been incorporated into the map, with some census blocks containing over 15,000 tests.
In 2021, South Carolina made the decision to no longer accept Digital Subscriber Lines as reliable service anywhere in the state. Doing so opened large regions of the state to investments, said Stritzinger, and will reduce the number of underserved locations.
The state’s next iteration of its map is set to come out sometime before June 30, and will be the state’s first address-level broadband map.
Stritzinger estimated that investments from the Broadband Equity Access and Deployment program will be deployed in 2025. In the meantime, the state will continue working to deploy the American Rescue Plan Act dollars, which allocated $25 billion in several broadband projects, $8 billion of which will go to states and local governments directly.

In Ask Me Anything!, Jim Stegeman of CostQuest Says Broadband Fabric Will Improve
Fabric data will continue to improve with feedback implementation and process changes, said CostQuest CEO.

WASHINGTON, May 12, 2023 – There are unrealistic expectations for the broadband mapping process despite its continual improvement, said Jim Stegeman, president and CEO of CostQuest, the mapping company that was hired to deliver fabric data to the Federal Communications Commission, during an Ask Me Anything! event in the broadband community on Friday.
“We will never get to allocation if we are after perfection,” said Stegeman, claiming that the company has been working hard to improve its processes over time.
The broadband fabric data is a dataset that maps all locations at which “fixed broadband internet access service has been or could be installed.” The FCC populates its National Broadband Map with the fabric data. The National Telecommunications and Information Administration has committed to allocating federal broadband funding by June 30 based on a version of the map.
Since its initial roll-out and subsequent challenge process – in which providers and state broadband offices have been able to challenge coverage claims by submitting contrary evidence – many have complained about the map’s many inaccuracies.
CostQuest maintains that the fabric identifies 99.3 percent of all broadband serviceable locations correctly and is “very good” where it stands.
Fabric will be continual improved
Stegeman outlined in his remarks areas in which the fabric and its processes will continue to improve in the coming iterations.
Each version of the fabric implements feedback, he said. Version two incorporated over a million new BSLs, 178,000 of which came from the FCC’s challenge process and 860,000 from CostQuest’s internal efforts to improve the fabric.
The FCC is currently in the process of releasing the next version of the National Broadband Map based on version two of the fabric data. This version of the map is expected to be the map which the NTIA allocates BEAD funding.
Subsequent iterations of the map will support state deployment and challenge processes, said Stegeman.
Version two also improved tribal land BSL identification by updating the logic that identifies whether a parcel of land holds a BSL and whether it contains multiple or single units.
Furthermore, through contractual agreement with the FCC, CostQuest has retained a file – facetiously titled the detritus file – that stores information on where water towers, sheds, chicken coops, and other agricultural buildings are located.
Precision agriculture, the process of using broadband to optimize agricultural production, requires broadband connection to these locations, often located miles away from homes and other BSLs. The FCC anticipates that this location data may be of future use, said Stegeman.
