Allocation of Frequencies in the Radio Spectrum

In the United States the National Telecommunications and Infonnation Administration (NTIA) has responsibility for assigning each portion of the radio spectrum (9 kHz to 300 GHz) for different uses. These assignments must be compatible with the rules of the International T elecommunications Union (ITU), to which the United States is bound by treaty. The current assignments are given in a wall chart (Reference 1) and may also be found on the NTIA web site (Reference 2). The list below summarizes the broad features of the spectrum allocation, with particular attention to those sections of scientific interest. The references should be consulted for details of the allocations in the frequency bands listed here, which in some cases are quite complex. 

Certain bands of the EMR spectrum have been allocated specific applications. The various radio frequency bands and their frequency ranges are shown in Table 2.7.
