Code of Federal Regulations – Title 47, Section 2.106
Revised on December 12, 2012
‘Selected Points of Interest’ are based on popular allocation applications, and may not be exhaustive or applicable for all nations.
This chart represents a single point in time of the International Telecommunications Union (ITU) worldwide spectral allocations summarized in the US FCC Code of Federal Regulations. As such, it does not completely reflect all aspects such as footnotes and recent changes. Users should always consult their national regulatory body for current allocations.
This chart does not differentiate between Co-PRIMARY and Secondary allocations. Allocations are listed from top to bottom in the order they appear in table 2.106. Horizontal scale has been exaggerated on some very narrow bands for readability.
