What is the Broadband Serviceable Location Fabric?

The National Broadband Serviceable Location Fabric is “a common data set of all residential and business locations (or structures) in the U.S. where fixed broadband internet access service is or can be installed. Each location in the Fabric is called a Broadband Serviceable Location (BSL), and the definition of a BSL is determined by the FCC. The Fabric is the foundational location database that is being used across several government programs, including NTIA’s BEAD, the FCC’s Broadband Data Collection, National Broadband Maps, and more. CostQuest is the official contractor and provider of the National Serviceable Location Fabric data.

Broadband Serviceable Location Fabric Version 4 Available

Fixed broadband service providers, government entities, and other designated entities are able to access Version 4 of the Broadband Serviceable Location Fabric (Fabric) to support the FCC’s Broadband Data Collection (BDC), the NTIA’s BEAD program, and other select federal programs.

Now that the March 2024 BDC Filing window is open service providers who are already licensees to use the FCC Fabric will receive an email from CostQuest providing them with access to the updated data on a rolling basis. (This email has been sent by CostQuest to FCC Fabric licensees.) Per the FCC’s public notice, “Entities that have not yet entered into a license agreement with CostQuest for Fabric data (including internet service providers, state, local, or Tribal governmental entities, or other entities wishing to use the Fabric data for purposes of participating in the BDC or non-commercial academic/public policy broadband research) may do so by following the instructions for obtaining access to the Fabric at the BDC Help Center” or on the second half of this web page.

The FCC Broadband Serviceable Location Fabric is “a key component of the BDC program because the Fabric data serves as the foundation on which fixed broadband providers’ availability data will be overlaid” on top of the Fabric locations to create their BDC Filings. The FCC Fabric in combination with broadband service availability data submitted by service providers in the BDC allows the FCC to create the National Broadband Map, to develop a granular picture of where broadband service is and most importantly, where it isn’t.
