Three Phase Power Line Carrier Communication

The Power Line Carrier Communication is a technology which uses power lines as physical media for data transmission. PLCC can offer a a no new wiresa solution because the infrastructure has already been established. PLCCs are used for transmitting data at a rapid speed through a power line in a house, an office, a building, and a factory, etc. Here, the existing alternating current (AC) power wires serve as a transmission medium by which information is relayed from a transmitter or control station to one or more receivers or loads connected downstream from an AC source. Typical applications of PLCC are Street light control, Automatic Meter Reading, HVAC control, Low Speed Data Networks, Signs and Information Display, Fire and Security Alarm etc. The PLC board developed by Prodigy Labs Pvt. Ltd. robust, low-cost way to communicate over power lines. The Embedded PLCC modem is based on the Differential Code Shift Keying (DCSK) Technology. This technology in Power Line Carrier ( PLCC ) communication is well known for its high immunity to electrical noise persistent in the power line.The PLCC Modem is in the form of a ready-to-go circuit module, which is capable of transferring data over the power cable at the low voltage end of the power transformer of a 3-phase/ 4-wire distribution network. A pair of Embedded PLCC Modems connected on the power line can provide low speed bidirectional data communication at a baud rate of 9600 bps.
