Broadband service availability and characteristics are depicted from data assembled by the Utah Governor’s Office of Economic Development and the Utah Automated Geographic Reference Center. Data sources include biannual broadband service provider submissions and publicly available sources. Data has been modified, where necessary, to meet broadband mapping standards.
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 Utah’s interactive broadband map is only for general reference purposes and may contain errors and omissions. The state of Utah makes no warranty for information or data available, express or implied, including but not limited to the fitness for use for a particular purpose.
All broadband mapping data 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 as well as verbal and written discussions.
An essential part of data validation is data intake and processing flow. Utah broadband data flow consists of:
- Initial evaluation of data submission and initial documentation
- Provider submission records
- Verify the data update is usable
- Data submission updates into 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 data consistency
- Record of discussions with the provider
- Create data feedback for the provider to review
Aerial photography, address location services, census block geometry, and road segment geometry used for broadband service mapping and quality control of the broadband data are from public domain resources in the State Geographic Information Database.
Broadband data received are reviewed for overall verification. Besides initial verification, other sample verification methods are listed below:
- Automated Geographic Reference Center maintains archives and documentation of a given provider’s data over time, and changes are noted and verified as to their plausibility. Since the project began in June 2010, all data-related interactions with providers have been documented. This provider submission history is periodically referenced to guide correspondence needs and special handling of the submission data.
- For each provider’s geographical extent, an examination of areas not served or 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 to verify that the data or updates have been prepared accurately. The most significant 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 state representatives during a scheduled conference.
- Local telecom territories are used to verify reported digital subscriber line 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 was used to assess broadband provider data and in verification discussions with wireless providers after being collected. It was also provided to all wireless providers for their own use.
- Before July 2011, commercial wireless data, such as the American Roamer data, was used to verify reported wireless coverage areas.
- To map the wireless data more accurately, the project mapping team has worked with providers to acquire wireless coverage areas based on signal propagation modeling. If a provider cannot 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.
