Carrier current is a method of low power AM radio transmission that uses the AC electrical system of a building to propagate a medium frequency AM signal to a relatively small area, such as a building or a group of buildings. In the United States, carrier current stations do not require a broadcasting license from the FCC, as long as the emissions adhere to the Part 15 Rules for unlicensed transmissions.

Famous quotes containing the words carrier and/or current:
“The problems of society will also be the problems of the predominant language of that society. It is the carrier of its perceptions, its attitudes, and its goals, for through it, the speakers absorb entrenched attitudes. The guilt of English then must be recognized and appreciated before its continued use can be advocated.”
—Njabulo Ndebele (b. 1948)
“We set up a certain aim, and put ourselves of our own will into the power of a certain current. Once having done that, we find ourselves committed to usages and customs which we had not before fully known, but from which we cannot depart without giving up the end which we have chosen. But we have no right, therefore, to claim that we are under the yoke of necessity. We might as well say that the man whom we see struggling vainly in the current of Niagara could not have helped jumping in.”
—Anna C. Brackett (1836–1911)
