Abstract:

The National Telecommunications and Information Administration (NTIA) launched this two-phase study of interference protection criteria (IPC) in order to compile, explain and validate, modify or supplement the levels of protection from interference that are generally expected and provided for various radiocommunication systems. The study is an integral part of President Bush’s Spectrum Policy Initiative that was established in May 2003 to promote the development and implementation of a United States spectrum policy for the 21st century. The Secretary of Commerce then established a Federal Government Spectrum Task Force and initiated a series of public meetings to address improvements in policies affecting spectrum use by the Federal Government, State, and local governments, and the private sector.

This report presents the results of the first phase of a two-phase study of interference protection criteria (IPC) to compile, explain and validate, modify or supplement the levels of protection from interference that are generally expected and provided for various radiocommunication systems. This report compiles IPC covering the frequency range 30 MHz to 30 GHz from generally accepted sources, including international agencies, government agencies, trade associations, academic institutions, and others.

The recommendations resulting from these activities were included in a two-part series of reports released by the Secretary of Commerce in June 2004, under the title Spectrum Policy for the 21st Century – The President's Spectrum Policy Initiative: Reports 1 and 2.^* Based on the recommendations contained in these Reports, the President directed the federal agencies on November 30, 2004, to plan the implementation of the 24 recommendations contained in the Reports. There were several recommendations that will consider the interference protection criteria contained in this study including:

assessment of new technologies and their impact on incumbent radiocommunications;

managing interference;

development of a “Best Practices Handbook” for spectrum engineering;

establishment a pilot program and long-range plan for improved sharing of spectrum between federal and non-federal entities; and

creation of new analytical computer models that will facilitate spectrum engineering.
