obtained for no cost under the earlier regulatory regime. When a regulatory regime changes to the property model, the original merit and cause guidelines for incumbent and grandfathered users are often removed. No regulatory review mechanism exists to check if the merit guidelines are still being followed, and if not, to then revoke the spectrum license from the incumbent spectrum owner and reissue the spectrum to a new user under old merit guidelines, or sell the spectrum inline with the new "spectrum as property" policy. U.S. regulatory agencies The Communications Act of 1934 grants authority for spectrum management to the President for all federal use (47 USC 305). The National Telecommunications and Information Administration (NTIA) manages the spectrum for the Federal Government. Its rules are found in the NTIA Manual of Regulations and Procedures for Federal Radio Frequency Management". The Federal Communications Commission (FCC) manages and regulates all domestic non-federal spectrum use (47 USC 301).

The Plenipotentiary Conference is the top policy-making body of the ITU, meeting every four years in order to set the Union's general policies. The ITU is divided into three Sectors: the Radiocommunication Sector (ITU-R) determines the technical characteristics and operational procedures for wireless services, and plays a vital role in the Spectrum Management of the radio-frequency; ITU-R Study Group 1 is the Spectrum Management study group; the Telecommunication Standardization Sector (ITU-T) develops internationally agreed technical and operating standards; and the Telecommunication Development Sector (ITU-D) fosters the expansion of telecommunications infrastructure in developing nations throughout the world, that make up two-thirds of the ITU's 191 Member States. The ITU Radio Regulations set a binding international treaty governing the use of the radio spectrum by some 40 different services. Frequency Administration In telecommunication, frequency assignment authority is the power granted for the administration, designation or delegation to an agency or administrator via treaty or law, to specify frequencies, frequency channels or frequency bands, in the electromagnetic spectrum for
