Stable data communication is the basic requirement for a smart low-voltage network. The importance of measuring devices for network status monitoring and network control technology continues to increase and the devices have to be integrated into the smart grid in way that enables communication. G3-PLC uses the existing power line for bidirectional data communication.


Older network control technology can also be integrated into the smart grid using the serial port on the G3-PLC modem 500k. This makes G3-PLC the perfect solution for obsolete forms of communication such as analogue telephones or CSD wireless system.
