Electrical Power Line Carrier

Electrical power line carrier systems allow signals to be simultaneously transmitted on electrical power lines. A power line carrier signal is transmitted above the standard 60 Hz power line power frequency (50 Hz in Europe). Power line premises distribution for television is important because televisions, set-top boxes, digital media adapters (DMAs) and other media devices are already connected to power outlets installed in homes and small businesses.

Older (legacy) power line communication systems had challenges with wiring systems that used two or more phases of electrical power. Today, with the benefit of modern signal processing techniques and algorithms, most of these impairments are no longer an impediment to performance and some powerline data systems have data transmission rates of over 500 Mbps.
