Understanding PLC Standards

Power line communication standards vary by region and application. In China, the primary standards are Q/GDW for State Grid and DL/T for China Southern Power Grid. These standards define physical layer parameters, communication protocols, and application layer requirements.

Narrowband vs Broadband PLC

Narrowband PLC (3-500kHz) is ideal for smart metering with data rates up to 10kbps and long communication range. Broadband PLC (2-30MHz) offers higher data rates up to 2Mbps but shorter range. Select narrowband for metering, broadband for high-speed applications.
