The Power Line Data Communication Module KQ-330 can transmit the broadband data via power line, which are suitable for either residential (at-home) or commercial (offices, apartments, hotels, warehouses) network applications, which utilize power lines. No need to install new wires any more, or you can connect the internet anywhere with the PLC. These adapters enable the effortless creation of a high-speed network that supports video, voice and data. Power line communication (PLC) carries data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. It is also known as power line carrier, power line digital subscriber line (PDSL), mains communication, power line telecom (PLT),power line networking (PLN), and broadband over power lines (BPL).
