[Why should the frequency assignments be notified to the ITU?] [The frequency assignments that may have international implications, as well as those for which the administration wishes to obtain international recognition, have to be notified to the ITU with a view to their recording in the Master International Frequency Register (MIFR). Once recorded in the MIFR, the concerned frequency assignments get an appropriate status that determines their relationship in respect to frequency assignments of other administrations. Consequently, some of the international rights can be claimed only in respect to those frequency assignments that are recorded in the MIFR, provided that the concerned frequency assignments got the appropriate status.]
