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:
“We know what the animals do, what are the needs of the beaver, the bear, the salmon, and other creatures, because long ago men married them and acquired this knowledge from their animal wives. Today the priests say we lie, but we know better.”
—native American belief, quoted by D. Jenness in “The Carrier Indians of the Bulkley River,” Bulletin no. 133, Bureau of American Ethnology (1943)
“What in fact have I achieved, however much it may seem? Bits and pieces ... trivialities. But here they won’t tolerate anything else, or anything more. If I wanted to take one step in advance of the current views and opinions of the day, that would put paid to any power I have. Do you know what we are ... those of us who count as pillars of society? We are society’s tools, neither more nor less.”
—Henrik Ibsen (1828–1906)
