The low voltage powerline communication has become a hot research topic for electrical advancements in recent years. This paper summarizes the state of research and application of low voltage powerline communication on the base of the characteristics of the low voltage powerline. The paper also compares three fundamental low voltage powerline communication technologies: Spread Spectrum Communication(SSC), Orthogonal Frequency Division Multiplexing(OFDM) and the traditional way (ASK: Amplitude-Shift Keying, FSK: Frequency-Shift Keying, PSK: Phase-Shift Keying). Some communication standards, such as X-10, LonWorks and CEBus, are analyzed. In addition, the paper proposes the latest solution and experiments and demonstrates the technology potential of the low voltage powerline communication .
