Data Submission Guidance

The Broadband Mapping Team coordinates data submissions with over 90 broadband providers throughout the state. As we reach out to providers, we are sensitive to the fact every provider is unique in terms of technical capabilities, resources and time availability. Our goal is to streamline the data submission process to reduce the time required for providers to prepare and submit data, while ensuring that the data we receive is of high quality so that we can create the best possible product for the State of Colorado.

The Team collects wireline and wireless broadband coverage data from providers in an effort to accurately portray these services on the public Colorado Broadband Map.


How to submit broadband data:

Please contact us at if you would like to submit broadband coverage data for inclusion on our maps.  If you have already been working with our mapping team, feel free to continue working with your point of contact.

If you do not have technical capabilities or resources to provide the data described below, our team can work with you to derive coverage from your existing data.


What data to submit:

Your data submission will consist of two sets of information: (1) Coverage area and (2) Attribution.

  1. Mapping data representing actual coverage service areas may be submitted in the following formats.  Acceptable data formats for wireline and wireless are listed here.
Wireline (DSL, fiber, cable, etc)Fixed Wireless

Wireline data consists of all wired technologies used to deliver broadband services, including DSL, copper wirelines, cable modem, and optical fiber.

The following data are accepted for wireline service areas:

  • Serviced Locations (Preferred)
    Acceptable formats:  Address Points or Latitude/Longitude Coordinates
  • Service Coverage Areas
    Acceptable formats:  GIS shapefiles or KML/KMZ Google Earth files
  • FCC Form 477 data
    We will accept census block level Form 477 data if you cannot provide more specific data.

Why are Serviced Locations preferred?

Serviced Locations data provides the most spatially accurate depiction of a wireline provider’s coverage area. The data is aggregated to Public Land Survey System Quarter-Quarter sections to ensure anonymity.  The addresses/point locations will not be shown or shared.  Furthermore, non-disclosure data agreements are readily available upon request.

The following data are accepted for fixed wireless service areas:

  • Tower/antennae data (Preferred)
    When submitting tower data, please include the following:

    • Latitude/Longitude of tower
    • Azimuth (degrees)
    • Beamwidth (degrees)
    • Max beam distance (note miles or km)
    • Antenna height (note ft or km)
    • Frequency (note GHz or MHz)
    • Transmit power (watts)
    • Antenna gain (dBI)
    • Beam tilt (degrees)
    • Maximum advertised download and upload speeds (in Mbps)
  • Propgated Coverage Model
    Acceptable formats:  GIS shapefiles, KML/KMZ Google Earth files, or upload

Why are Tower/antennae data preferred?

Tower/antennae data is the most desirable data, as the Team uses the propagation simulation software Radio Mobile to input antennae settings, which in turn creates a propagated coverage model based on those settings.

  1. Certain attribution is needed to finalize the submission:
    • Required Attribution:
      • Provider DBA Name
      • Technology of transmission
      • Spectrum (Wireless only)
      • Service type: Residential, commercial or both
      • Maximum advertised download and upload speeds (in Mbps)
      • Pricing: Monthly prices for each speed/service package currently deployed
    • Other useful attribution:
      • Maximum subscriber download and upload speeds (in Mbps)
      • Maximum typical download and upload speeds (in Mbps)
