The Middle Class Tax Relief & Job Creation Act of 2012 contained provisions in Title VI that expedite the availability of spectrum for commercial mobile broadband. The provisions in Title VI -- also known as the Public Safety and Spectrum Act, or the Spectrum Act -- cover reallocation of spectrum, new assignments of spectrum rights, and changes in procedures for repurposing spectrum used by the federal government. This book discusses emerging issues in the spectrum management and policies in the United States.
