The Utah Broadband Center (UBC) in partnership with the state’s Utah Geospatial Resource Center (UGRC), works with broadband providers to keep current mapping data on broadband availability in Utah. The broadband mapping data is used to inform stakeholders on the broadband landscape in Utah and other special mapping projects or requests. 

To submit broadband coverage data for inclusion on our maps, contact Rebecca Dilg below. 

The UBC collects mapping data on fixed and mobile broadband service marketed primarily towards the residential market. Fixed services include service directly to an end-user over a fixed connection via fixed wireless, cable, DSL, fiber to the home, or another copper wireline.

How to Submit Residential Broadband Data

  1. Mapping data representing actual coverage service areas may be submitted in the following formats:
    1. Google Earth KMZ files or ESRI GIS files.
    2. Hardcopy or digital service coverage map.
    3. Infrastructure information to derive service coverage. All infrastructure data is kept proprietary
    4. Fixed wireless providers are requested to submit tower locations and related information. The Center will derive a line-of-sight coverage footprint for provider review.
  2. Basic information is needed to finalize your submission:
    1. Provider DBA Name
    2. Technology of transmission (mobile, fixed wireless, DSL, fiber to the home, or other copper wireline)
    3. Actual maximum advertised download and upload speeds marketed to a residential market. Advertised speeds must be able to be confirmed by the Center.


How to Submit Commercial Broadband Data

Commercial Broadband Mapping Data maps commercial fiber availability. It also utilizes the residential broadband mapping data to communicate what providers are in a given area. There are two categories of commercial fiber service, short-term (service can be provided within an average time frame of 1-3 months) and custom (service can be provided within an average time frame of 3-9 months). Fiber availability is aggregated to a statewide grid.

Broadband providers that provide fiber to commercial end users can submit mapping data with Google Earth KMZ files or ESRI files.

Data Submission Deadlines

For Broadband Providers

Residential broadband data is collected every six months generally in March and September.

Commercial fiber broadband providers will be reminded to update their data during the two data update rounds. 


Data Quality


An important part of data validation is the UBC’s data intake and processing flow. In summary, our data flow consists of:

Aerial photography, address location services, census block geometry, and road segment geometry used for broadband service mapping and for quality control of the broadband data are from public domain resources in the SGID.


All Broadband data received by the UBS/UGRC is reviewed for overall verification. Besides our initial verification, other sample verification methods are listed below.
