Power Line Carrier (PLC) – the transmission of signals across utility power lines or existing electrical home wiring. Using a high frequency carrier applied to the wiring, frequencies may range from 8 kHz to 200 kHz and above.
Transformer - a device that uses magnetic force to transfer electrical energy from one coil of wire to another. In the process transformers can also change the voltage that this electrical energy is transmitted.
Reflector Lamp (R-Lamp) - an incandescent filament, or electric discharge lamp where the sides of the outer blown-glass bulb are coated with a reflecting material so as to direct the light. The light-transmitting region may be clear, frosted, or patterned.
