| Abstract: | Based on the the new requirements of smart grid and AMI on automatic meter reading system, this paper analyses the limitations of low speed PLC modulation technologies, and points out that OFDM muti-carrier technology is the effective solution because of its inherent adaptation capability in power line channel conditions.It introduces the OFDM modulation principle, receiver technology and the design of APLNET-iM, an OFDM-based advanced power line networking technology for smart metering in China. |
