Theoretical evaluation of band 7 frequency complements for ocean data communications

George W. Haydon

Abstract: A study has been conducted to evaluate selected complements of Band 7 frequencies (3-30 MHz) by the application of radio propagation data to a hypothetical deployment of ocean buoys about base stations in various geographic areas. The relative utility of selected frequencies and the utility of these frequencies in combinations of 4, 5, or 6 is considered as a function of latitude and distances to the buoys. Data to estimate the feasibility of frequency sharing by geographic or time separation are included in the report.
