Unlicensed Radio Stations
In the United States, most radio stations are licensed by the Federal
Communications Commision (FCC). However, if a transmitter has very low
power and is unlikely to interfere with other radio stations, then it
may fall under the category of "Part 15 Devices
" and it may be
legal to operate without a license.
Here are a few of the most common types of low-power, unlicensed
- Carrier-Current AM
- Transmits AM radio signals through a building's AC power wiring.
- Leaky Cable FM
- Similar to carrier-current, except that instead of using the building's existing
wiring, a special type of "leaky" coaxial cable is run through the
building, usually down hallways.
- Micropower Stations
- These stations simply use very
low power transmitters to broadcast their signals to a small area, such as
a college campus.
