Those treaties, laws, and regulations have divided the spectrum by type of service use, (e.g., radio navigation, aeronautical mobile, fixed-satellite, and mobile satellite), by user (e.g., Government and non-government), and by region (1) Europe, Africa, Former Soviet Union, and Near East; (2) Western Hemisphere; and (3) Far East and Western Pacific.

. Any new federal government system that seeks to use a portion of the spectrum must seek both a frequency allocation and a frequency assignment. Normally, new systems can not interfere with older systems with prior equal or higher status (e.g., primary or secondary) assignment.
If a new system does not conform with the existing treaties, laws and regulations, it can only operate on a “not to interfere basis” (NIB) with other approved systems.
The DoD Policy on Electromagnetic Spectrum – Management and Use (DoDD 4650.1) provides specific requirements that program offices must meet when developing and using RF systems. It states, “Spectrum-dependent equipment or systems shall not be developed or procured without reasonable assurance that required electromagnetic spectrum is, or shall be, available to support the development, testing, and operation of that equipment or system.”
DoDD 4650.1 further states that “No spectrum-dependent ‘off-the-shelf” system shall be purchased or procured without the assurance that spectrum supportability has been, or can be obtained.”
Finally, DoDD 4650.1 requires the acquisition community to insure compliance with supportability requirements and to provide oversight to the process prior to and through the development, test and evaluation phases of a system. Since systems are designed within the U.S., they must meet U.S. requirements, and since there is no way of predicting where they may be used “outside the U.S.,” it is necessary to consider the potential limitations of International Law/International Treaties on the development of unmanned aircraft systems. Spectrum flexibility in development must be a consideration, or International Law must accommodate use of military systems regardless of the country of origin.
