About the Interactive Broadband Map

Broadband Map Disclaimer

Broadband service availability and characteristics are depicted as derived from data assembled by the Utah Broadband Outreach Center. Data sources include biannual broadband service provider submissions and publicly available sources. Data has been modified, where necessary, to meet broadband mapping standards set by the Broadband Outreach Center.

Speeds shown are the ‘maximum advertised’ for the geographic features depicted, and must exceed 0.768 Mbps download and 0.2 Mbps upload to be included. Actual speeds may vary within and along census blocks and roads due to the granularity and currency of the data, technological limitations, and service plan limitations. Users of this data and associated map visualizations are encouraged to inquire directly to providers for current service availability and speed.

All information presented on the Utah’s interactive broadband map is for general reference purposes only and may contain errors and omissions. The State of Utah makes no warranty with respect to information available, express or implied, including but not limited to the fitness for use for a particular purpose.

Map Data Description

All broadband mapping data either is sourced directly from a broadband provider, or from working directly with a provider.

Wireless broadband internet data is mapped using coverage area footprints derived from analyzing antennae location, signal strength and terrain. Wireline broadband internet data is mapped using provider reported availability footprints in developed areas.

Once a provider’s broadband coverage is initially mapped, data updates take several forms including GIS files, written descriptions, provider created maps, and verbal and written discussions.

Validation

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

  • Initial evaluation of data submission and initial documentation.
    • Recordation what was submitted by provider.
    • Verification that the data update is usable.
  • Data submission updates in to a standard data model.
  • Detailed evaluation and documentation.
    • Document details of the data and the data processing steps.
    • Review the provider’s changes from previous submissions for consistency between what is in the data and what discussions have been made with providers.
  • Create data feedback for provider to review.

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.

Verification

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

  • The Center maintains archives and documentation of a given provider’s data over time, and changes are noted and verified as to their plausibility. All data related interaction with a provider since the project began in June 2010 is also documented. This provider submission history is periodically referred to in order to guide correspondence needs and special handling of the submission data.
  • For each provider’s geographical extent, examination of areas that are not served or are underserved is completed and discussed with the provider for accuracy.
  • Every time the project receives updates from a broadband provider, data feedback is sent to the provider for them to verify that the data or updates have been prepared accurately. The biggest source of feedback for providers is being able to interact one on one with their specific data on the Utah Residential Broadband Map. Providers can do this on their own or with the project during a scheduled conference.
  • Local telecom territories are used to verify reported DSL coverage areas.
  • Wireless Drive Test: In July 2011 and November 2013, the Utah Broadband Outreach Center contracted with Isotrope LLC, a Massachusetts-based company, to perform a drive test to assess wireless broadband services and capabilities throughout the state. The drive test data, collected by traversing over 6000 miles of the state , provides a snapshot in time of mobile broadband speeds, signal strength and technologies. After being collected, the drive test data was used to assess broadband provider data and was used in verification discussions with wireless providers. It was also provided to all wireless providers for their own use.
  • Prior to July 2011, commercial wireless data such as the American Roamer data was used to verify reported wireless coverage areas.
  • In order to map the wireless data more accurately, whenever possible the project mapping team has worked with providers to acquire wireless coverage areas based on signal propagation modeling. If a provider does not have the capacity to submit a propagated coverage area, the project encourages providers to provide tower locations and antenna locations and specifications to the project mapping team that are then used for a viewshed to create a propagated coverage area.

Additional Utah Broadband Maps and Data Resources

The Utah Broadband Outreach Center maintains additional maps beyond the online interactive map. These are available on request and include maps of broadband coverage availability, best available speed, and highest order technology in Utah. The Center is also willing to work on other specific mapping requests.  Click here to view these resources.

About the State Level Broadband Map

The Utah Residential Broadband Map was developed and is hosted by the Utah Automated Geographic Reference Center (AGRC) utilizing data complied by the Project from broadband providers and public sources, including Utah’s State Geographic Information Database (SGID) which is utilized extensively for locating addresses, locating geographic places, and displaying background maps.

Map Goals

  • The map attempts to provide consumers, community leaders, and broadband providers with a comprehensive map-based view of non-confidential data complied by the Utah Broadband Outreach Center.
  • The map is also meant to be used by policy makers or policy maker supporters, such as the Utah Broadband Advisory Council.
  • The map serves as a basis of discussion with Broadband Providers to verify accuracy of data.
  • The data on the map is used in our twice yearly submission to the NTIA.
