To Transmit Additionally Information

Powerline Communication (PLC) solutions do offer a good possibility to use all kind of available wiring infrastructure to transmit additionally information over it without having to install new cables, even so the original use of the cabling was different.

By using PLC on existing wiring Ethernet packets with high data rates for example can be distributed and transmitted over the mains installation in the house. Sensor data, metering data from power, energy, gas, water meters and e.g. control information can be collected and distributed. Telephone and bell wires can be used to implement IP based door phone communication or access control systems like finger print readers and face recognition systems. In addition, the usually existing coax cable TV installation in the house can be enhanced to become a data bus by using PLC, also known as Ethernet-over-Coax (EoC) technology.

In the area of Powerline Communication CODICO offers integrated circuits and modules as well as development tools.

Powerline Communication for E-Mobility and Other Applications

During the past years, the use of PLC as communication technology has increased rapidly in the area of eMobility, means for communication between electro vehicle (EV) and their charging station (EVSE). There the international standards and standards ISO/IEC 15118, DIN 70121 and SAE J2847/2 define the use of HomePlug Green Phy, be it for control of the charge process itself as well as for information exchange between electro vehicle and the utility for identification and billing of the electricity purchase for the charge on public charging stations.

Further applications of PLC are in the area of Smart Metering, means the remote and automated meter reading or in the implementation of intelligent power grids - called Smart Grids - whereas the communication usually takes place on the power network itself. Powerline Communication is as well qualified for every conceivable industrial application, be it for additional communication over the onboard power network of vehicles and vessels, the communication between wagons in trains via the tow coupling, communication via slip rings or sliding contacts. The applications of Powerline Communication on existing cable infrastructure are practically unlimited.
