Eastsoft PLC Chip Selection Guide
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.

Frequently Asked Questions
1. What is the difference between Q/GDW and DL/T standards?
Q/GDW standards are used by State Grid Corporation of China, while DL/T standards are used by China Southern Power Grid. Both specify PLC communication for smart meters but with some technical differences. Eastsoft chips support both standards.
2. How do I evaluate PLC communication range?
PLC range depends on line conditions, load characteristics, and noise levels. Conduct field testing in the target environment. Typical range is 500m-2km for narrowband PLC. Use concentrators for larger networks.
