Comparison of narrow-band OFDM PLC solutions and I-UWB modulation over distribution grids

To support the requirements of smart grids (SGs) applications, telecommunication industries and standardization organizations have proposed to use narrow-band (NB) orthogonal frequency division multiplexing (OFDM) based solutions over power line communications (PLCs) networks. Among these solutions, the most important are the PoweRline Intelligent Metering Evolution (PRIME), the ERDF G3-PLC, and the G3-FCC.
