The Federal Communications Commission is proposing a 10-year plan which will reinvent America’s media and technology priorities by establishing high-speed Internet as the nation’s dominant communication network. The plan will be submitted to Congress this week.

The blueprint underscores the government’s view that broadband Internet is becoming the common medium of the United States, gradually displacing the telephone and broadcast television industries. It also signals a shift at the F.C.C., which under the George W. Bush administration, gained more attention for policing indecency on the television airwaves than for promoting Internet access.

According to F.C.C. officials briefed on the plan, the commission’s recommendations include a subsidy for Internet providers to wire rural parts of the country, currently without access, a controversial auction of some broadcast spectrum to free up space for wireless devices, and also the development of a new universal set-top box that connects to the Internet and cable service. The effort will influence billions of dollars in federal spending.

About a third of Americans have no access to high-speed Internet service; either they cannot afford it or choose not to have it. The plan should enlighten and plug-in all citizens, envisioning a fully Web-connected world with split-second access to health care information and online classrooms, delivered through wireless devices.

The F.C.C. plan includes reforms to the Universal Service Fund, which spends $8 billion a year from telephone surcharges to ensure that rural and poor people have phone lines at home. It also supplies Internet access to schools, libraries and rural clinics.

In recent weeks, a much-talked-about idea in the television industry has been a voluntary auction of over-the-air spectrum for future mobile broadband uses. The F.C.C. is trying to free up roughly 500 megahertz of spectrum, much of which would come from television broadcasters, which would be compensated if Congress acts.

Of course the proposal already faces resistance from the TV industry. Stations say they still serve a valuable public service, especially during emergencies, and say the F.C.C. proposal could cause gaps in signal coverage.
