What is Broadband Serviceable Fabric Location Data?

CostQuest’s Broadband Serviceable Fabric Location (BroadbandFabric) Data is a database of over 115 million individual location structures where a broadband connection is or can be installed. CostQuest refers to these locations as “Broadband Serviceable Locations.” All Broadband Serviceable Locations include residential, business, multi-dwelling, CAI, agricultural, and other location types. This dataset ties easily with other data layers using a universal unique location ID, and aligns with the National Broadband Serviceable Location Fabric dataset used for the Broadband Data Collection, National Broadband Map, and other federal programs.

CostQuest’s Broadband Serviceable Location Fabric Data

The Broadband Serviceable Location Fabric dataset comes in an Excel .CSV file format and can be imported into any major GIS application, network planning software, SQL, or other related applications. Built by broadband experts and blended with machine learning, the Broadband Serviceable Locations dataset is built to be the perfect guide for broadband deployment, business planning, and policy decisions.

The Broadband Serviceable Location Fabric dataset contains the exact coordinates of all structures where a broadband connection is or can be installed, and provides you with the level of granularity needed to identify the exact geographic locations of end-users, and assist in qualifying whether they currently receive, can receive, or need broadband service.

Reliable information for effective decisions & successful planning

To make intelligent and effective decisions, it’s critical to have reliable information that guides you in the right direction. The Broadband Serviceable Location Fabric dataset provides you with the precise coordinates, address, building type, and other essenital location inisghts to act as a reliable resource for data-driven decisions.


Federal agencies, service providers, and other stakeholders, rely on CostQuest’s models and expertise to inform critical broadband initiatives and reform policies. CostQuest’s financial models and Broadband Fabric data, used by the FCC and NTIA, supports the Broadband Data Collection, BEAD, and other funding programs. Our work is reviewed regularly, withstanding the highest levels of scrutiny to ensure the work is foundationally sound.

How CostQuest Identifies Broadband Serviceable Locations

To get pinpoint accuracy for all locations, CostQuest categorizes as Broadband Serviceable Locations; the team aggregates hundreds of millions of data points, applies statistical scoring, and managed crowdsourcing to identify the precise locations of virtually every structure that is a candidate for broadband.

Step 1: Start with a Geographic Frame of Reference

When looking for Broadband Serviceable Locations (BSLs), CostQuest starts by obtaining rich geospatial information across all 50 states and territories to create a geographic frame of reference to start the analysis. CostQuest uses parcel information to create the geographic frame of reference, or the “sandbox” to work from, to provide boundaries of where to look for a structure/building within a piece of geography. CostQuest then ties in additional data sources to further the team’s understanding of the land and building use within each geographic frame.

The red lines represent geographic frames of reference a.k.a. parcel boundaries.

Step 2: Link County Tax Assessor Information

County Tax Assessor attributes provide more details about a piece of geography – what it is used for, the address, the value of the property and any building on it, and more. By analyzing the tax attributes of each geographic frame of reference, CostQuest can isolate characteristics at a location level. Statistical scoring is used to systematically consider each attribute to answer a question: is this piece of geography likely to contain a structure that may require broadband service or a technical term CostQuest calls a Fabric Active structure?

Step 3: Connect Geographic Frames and Tax Assessor Information with Building Footprints

CostQuest then uses building footprints to look at all the possible buildings within each geographic frame of reference. These footprints give CostQuest the geospatial coordinates of each structure on that individual piece of property.

What CostQuest derives from the tax assessor attributes is then compared to what is seen in the building footprints. Rooftop detail, size, and building shape help us determine which building is the likely point where broadband service will be accessed. The structures are visually identified and assessed for confidence.

The red-shaded shapes above each location structure represent the building footprint.

Step 4: Connect other data sources

A. CostQuests connects additional data sources using a universal location identifier tied to each Broadband Serviceable Location to help inform the model as to which location structures are candidates for broadband. The data sources are updated semi-annually. All the data sources include:

  • Parcels​
  • Satellite Imagery ​
  • Commercial building footprints​
  • Tax Attributes​
  • Address datasets​
  • Road Segments​
  • US Census

B. More data can be linked to the locations to learn more about specific areas of interest. For example, broadband service availability, deployment cost information, federally funded locations, build complexity, demographics, and the competitive landscape.

Step 5: Identify Broadband Serviceable Locations

Final Result: Using conditional logic, CostQuest sets rules that connect building footprints from aerial imagery, tax attributes, road segments, U.S. Census, parcels, addresses, land cover data, and more to pinpoint and display the precise coordinates of each Broadband Serviceable Location (structure) that is the likely point where broadband service will be accessed.

The circled locations with a green dot represent the identified Broadband Serviceable Location in each geographic frame of reference.

Step 6: Human Visual Verification

Visual verification is an internal process CostQuest uses to have human beings review locations that our models aren’t confident in. This step is critical in adding human oversight to improve machine learning in selecting the appropriate location structure within a geographic frame.

The circled locations with a green dot and check represent the identified and visually verified Broadband Serviceable Location in each geographic frame of reference.
