Regulations for Spectrum Sharing in the USA

The regulation of spectrum in the United States is managed by two independent agencies: the National Telecommunications and Information Administration, who is responsible for spectrum used by US government agencies such as the Department of Defense and the National Weather Service, and the Federal Communications Commission, who is responsible for all non‐federal spectrum. Both agencies are mandated by law to maximize the efficient use of spectrum, and toward that end, both agencies are working to share underutilized spectrum to the greatest extent possible. This chapter will explore various initiatives by these two agencies to achieve this objective, both independently and in cooperation.
