G3-PLC specification for powerline communication: Overview, system simulation and field trial results

摘要

An overview of a new physical layer specification for powerline communication, named G3-PLC, is presented. The specification uses OFDM for data transmission and is intended to operate in the low-frequency band, from 35.9 kHz to 90.6 kHz. Simulation results are presented showing the expected performance of a typical G3-PLC-compliant modem when operating in a powerline channel, followed by field trial results showing performance of several G3-PLC modems operating on actual MV and LV powerline channels. In particular, results are presented for the first time showing performance of modems residing on opposite sides of a 20kV – 220V transformer that interfaces an MV powerline to an LV powerline.
