  1. Broadband Verification: Space & Frontier Bert Granberg & Rick Kelson Utah AGRC

  2. Utah NTIA Broadband Mapping and Planning Project • Grantee: Public Service Commission • Project Partners: • Governor’s Office of Economic Development • Department of Technology Services • AGRC (state GIS office) • Contractor: (~ 1/3 of yrs 1-2 budget) • IRC (Tempe AZ), Provider Engagement • Inventory, Outreach, NDAs, Technical Assistance, Some Verification

  3. FCC Consumer Speed Test Data 2 Topics • Satellite Modeling

  4. Satellite Coverage Provider Submissions • Providers suggest ubiquitous service • Relevance: • Meets minimum broadband speed definition • May be only option in locations • Question: Verification for this technology type, Effort?

  5. Can We Use GIS to Model Satellite Dead Zones? • ArcGIS Spatial Analyst Hillshade tool...with ‘Model Shadows’ functionality • Note: Viewshed tool doesn't work, observation point (satellite) would need to be within extent of GIS terrain model • 10 meter statewide Digital Elevation Model • Input Parameters: • Satellite Azimuth Position (Longitude) • varies by provider, available on web (ex. 111.1° W) • Satellite's angle above horizon --> TRIG analysis

  6. Trig for Satellite Angle Above Horizon • Geostationary Orbit Distance: 22236 Miles • Earth Radius: 3963 Miles • Observation Point: 39.5° N (avg. Utah Latitude) • SohCahToa: α Solution: Angle Above Horizon For Utah ~ 44.3 °

  7. Analysis Results: • Shadows exist (shown in Red) • North faces of steep-walled mountain & desert canyons • Designated or defacto wilderness • Very few structures • One exception found: • Timpanogos Cave Natl. Monument (below)

  8. Satellite Modeling Conclusions • Statewide Availability • Empirically: Not quite • Practically: Yes • Buildings, trees not accounted for • Satellite BB is probably last choice in urban areas • Trees not a huge UT issue • Analysis should hold for other satellite services More info: • http://gis.utah.gov/agrc-mobile-communications/satellite-broadband-service-terrain-shadow-modeling-for-utah

  9. FCC Speed Tests: • Data from FCC every month via submission site • Utah: 6000+ records in first 2 months • Three datasets: • 1) Browser-based speed tests • User supplied address --> Geocode • 2) Droid and iPhone Mobile App speed tests • Wifi OR Cell Network -based) • Lat/Long • 3) Deadzone reports • All tests  IP addresses of test machine –> arin.net

  10. American Registry of Internet Numbers (arin.net) • WhoIs? Service • IP --> Registering organization • Organization --> IP Blocks • Residual Anonymous IPs • Internal IP blocks • Third party registered blocks • "Service Provider Corporation"

  11. Speed Test Maps & Data • Master speed test table • Speed • Test Type • IP • Date, etc • Provider (from ARIN) • XY Coords (geocode) • Census Block ID Assignment • Speed test summary by census block (All or By Specific Provider) • Min Speed • Average • Max Speed • # of tests • Deadzone report points

  12. How to use for Validation: • Inclusion in provider feedback process? • Incorporate in confidence scoring of provider submissions? • Show as layer on state broadband interactive map? • Other uses?

  13. FCC Speed Test Conclusions • Loads of potential • Need more tests • UT is developing own speed test with visual address verification • Will promote test through PR outreach • Will combine results w/ FCC test & report to NTIA

  14. Questions and Discussion • Contact Info • Bert Granberg, Utah AGRC • bgranberg@utah.gov
