Carrier current transmission (originally called wired wireless) employs guided low-power radio signals, which are transmitted along electrical conductors.  The transmissions are picked up by receivers that are either connected to, or a short distance from, the conductors.  Carrier current transmission is used to send audio and telemetry to selected locations, and also for low-power broadcasting that covers a small geographical area, such as a college campus.  The most common form of carrier current uses longwave or mediumwave AM radio signals that are sent through existing electrical wiring, although other conductors can be used, such as telephone lines.
