What is the Broadband Serviceable Location Fabric?

The FCC’s Broadband Serviceable Location Fabric is a dataset of the geographic coordinates of all locations (building structures) in the United States where a broadband connection can be installed (also referred to as Broadband Serviceable Locations).

Please see the listed steps below to learn how you can get access to the FCC’s Fabric. If you need any assistance, please email nbfsupport@costquest.com.

FCC’s Broadband Serviceable Location Fabric is now available

The FCC has officially announced that fixed broadband service providers and government entities may now access the production version of the Broadband Serviceable Location Fabric (Fabric). The FCC’s Broadband Serviceable Location Fabric data is now currently available for all 50 states and the District of Columbia. 

This production version of the FCC’s Fabric is available for filers (fixed service providers) to use to match their broadband availability data to locations in the Fabric to prepare their filings for the Broadband Data Collection (BDC). The Broadband Serviceable Location Fabric is “a key component of the BDC because it will serve as the foundation on which fixed broadband providers’ availability data will be overlaid.” The FCC’s Fabric in combination with broadband availability data submitted by service providers will contribute to the FCC’s National Broadband Map, to help better understand where broadband service is and most importantly, where it isn’t.

Broadband availability data can be submitted in the BDC starting June 30th, 2022, and due no later than September 1, 2022. 

Service providers and government entities will have access to the following data in the Broadband Serviceable Location Fabric:

  • Coordinates of building structures where a broadband connection can be installed
  • FabricID: A universal identifier assigned to each location’s broadband serviceable structure for teams to use to tie their broadband service availability data to the Fabric ID of each structure located in the Fabric.

Service providers and government entities that get access to the FCC’s Fabric can only use the data for filing into the Broadband Data Collection.

Want data you can use for Broadband Data Collection filings, service mapping, network planning, design, AND more?

1. How to access the FCC’s Broadband Serviceable Location Fabric  

To gain access to the FCC’s Broadband Serviceable Location Fabric data, eligible providers must execute a limited end-user license agreement with CostQuest Associates.

Already have the preliminary Fabric?

If you accessed the preliminary Fabric (as outlined in the First Fabric Public Notice), you do not need to execute a new license agreement. In this instance, the Commissions Fabric Contractor, CostQuest, will send you via email a link to access the production Fabric data files.

Per the First Fabric Public Notice, “each company’s data will contain Fabric records only for the counties that overlap the Census Blocks reported in the filer’s Form 477 fixed broadband deployment data.”

How to access the FCC Fabric: Step-by-step 

For Service Providers

  1. Fixed broadband service providers may now access the production Fabric by sending an email to CostQuest at nbfsupport@costquest.com with the name and email of the provider’s contact person, the provider’s name, and the provider’s FCC Registration Number (FRN).
  2. CostQuest will provide those users with instructions on how to access the Fabric, which can be done after the user completes an online form and executes a license agreement with CostQuest.

for State, Local, and Tribal Governments

  1. Governmental entities must obtain an FRN, log into the BDC system using the account information (username and password) created in the Commission Registration System (CORES), and complete the entity information form.
  2. After the governmental entity submits the necessary information in the BDC system, FCC staff will review the information and provide the contact information of approved entities to CostQuest.
  3. CostQuest will then send an email invitation to the entity, which the entity can use to request access to the Fabric and execute a license agreement. Government entities should note that, as with service providers, their license will cover only the counties in their jurisdiction.
  4. Following the execution of a license agreement, CostQuest will make the Fabric data files available to governmental entities. CostQuest will process license requests as quickly as possible but, depending on the number of pending requests from providers and governmental entities, delivery of the data files may take up to two weeks from the time the entity information is submitted in the BDC system.

2. The FCC Broadband Serviceable Location Fabric data sources and elements 

The data sources that will be used to identify locations (including Broadband Serviceable Locations) listed in the FCC’s Fabric include a combination of: 

  • Satellite imagery 
  • Building footprints 
  • Address databases 
  • Land and local tax records 
  • Other sources that the vendor finds as either necessary or beneficial for determining the locations of structures throughout the U.S. where fixed broadband service can be installed 

3. Specifications from the FCC on BDC submissions 

“Filers seeking to submit lists of addresses or locations, as opposed to submitting availability polygons, will need to match their location data to locations in the Fabric.”

It is required that providers associate their location availability data to the Commission-issued Location IDs in the Fabric to be consistent with the Broadband Data Act (BDA) requirements. Submitting the Location ID for each of their Broadband Serviceable Locations will ensure that the Commission will collect availability data that “can be georeferenced to the data in the Fabric” and will result in a more accurate and complete broadband locations database. 

Notes from the FCC 

“Filing broadband availability data based upon the Fabric is a new process, so we expect that it will take providers some time to work through their methodology for aligning their internal served location data with the Fabric, and then to generate the data required for filing in the BDC system.” This data filed in the BDC is critical for federal and state policymakers to distribute the broadband deployment funds made available by Congress in the Infrastructure Investment and Jobs Act’s Broadband Equity, Access, and Deployment program.
