gPLC Home Gateway Module LHM980B-350D-002

This small gPLC module is for Gateway or master-node terminal of smart homes. The module operates as a master node in gPLC domain and is responsible for managing the domain and communicating with sub-nodes through power line. The management functions include sub-node registration, routine management, etc. The module has UART port to interface with external host CPU.

gPLC is a narrow-band & high-speed PLC technology based on OFDM modulation and zero-crossing transmission (Z-OFDM) and has robust performance in interferring and noisy power line channels. gPLC complies with China national standard of power line communication GB31983-31.
