Outline about the EMC properties and Throughputs of the PLC systems up to 100 MHz

摘要

Advanced communication technologies has allowed the powerline communication (PLC) channel to be a transmission medium that enables the transferring of high-speed digital data over the classical indoor electrical wires. Nowadays, the 200 Mbits/s theoretical rates of the Homeplug AV specification are no still sufficient for transferring Internet, voice, HD videos, and data services simultaneously through the electrical support, especially as real data merely exceed 70 Mbits/s. In this note, a brief Electromagnetic Compatibility analysis and throughput calculation of the PLC systems is carried out. The frequency band up to 30 MHz, characterizing PLC modems, is here pushed up to 100MHz. The investigation is aimed to increase PLC throughputs by extending the frequency band above 30MHz.
