APPENDIX A - SPECTRUM USAGE PLOTS: 1300-1390 MHZ BAND

Sep 12, 2026

This document presents spectrum usage contour plots for the 1300-1390 MHz band across the contiguous United States. The plots are segmented into 5 MHz intervals within this band and are generated using December 2015 GMF frequency assignment data. Notably, these visualizations exclude frequency assignments for U.S. territories and possessions. The intensity or opacity of the plotted areas on these spectrum usage contour maps directly corresponds to the time of usage for transmit or receive stations. Specifically, usage between 50 percent to 100 percent is represented by 100 percent opacity, 10 percent to 50 percent by 75 percent opacity, 1 percent to 10 percent by 50 percent opacity, and less than 1 percent by 25 percent opacity. The appendix details figures for each 5 MHz segment from 1300-1305 MHz up to 1385-1390 MHz, visualized on a map of the United States.

FAQs

What is the primary focus of Appendix A?

Appendix A provides spectrum usage contour plots for the 1300-1390 MHz band across the contiguous United States.

How is the time of usage displayed on the spectrum usage contour plots?

The time of usage for transmit or receive stations is represented by the opacity of the plots, with higher opacity indicating more frequent usage.

What frequency assignment data was used to generate these plots?

The plots were generated using the December 2015 GMF frequency assignment data.

Do the spectrum usage contour plots include frequency assignments for U.S. territories and possessions?

No, the geographic usage displayed in these plots does not include United States and Possessions frequency assignments.
