Map Notes

Developed by Anthony Fiti (Twitter).

All data was sourced from the FCC License View (originally, it was sourced from the FCC’s Spectrum Dashboard). As time moves forward, this data might not be 100% complete or accurate. I make no claim as to the accuracy of this data. If you have a problem with it, double check it with the FCC’s online database, then take it up with them.

All names and colors are trademarked/copyright of their respective owners, I take no claim of ownership.

Known Map Issues

  • The map does not include Hawaii, Alaska, PR, American Samoa, etc. I left them off because I’m focused on the lower 48. Generally speaking, outside of the lower 48, spectrum isn’t in that desperate of a need because there isn’t sufficient population density to worry about it.
  • In some cases, a regional license can be divided in terms of both frequency (subdividing a 10MHz chunk of spectrum into two 5MHz pieces for the entire area) or in terms of geography, or both. For example, AWS-1 block E (1740-1745, 2140-2145) Western Region is owned by AT&T, however they let MetroPCS use this spectrum in Santa Barbara County, CA – this is geographical division. My mapping system doesn’t support that, so it just looks like they both own that slice of spectrum. The problem with trying to fix this problem is that Google Maps can barely handle the cellular regions as-is, trying to subdivide the regions into counties will overwhelm the web browser. In particular the Broadband PCS spectrum is a giant mess. I’m trying to come up with a better way to visualize spectrum ownership in this area.
  • This does not include the 20×20 spectrum Echostar owns (2000-2020, 2180-2200) which could be used for really fast LTE services, though apparently they are more fixated on serving up television in that space. Maybe VOD would work, but not a meaningful number of stations.
