Abstract:This article summarizes the access network situation of China and poses a topology using powerline communication as a method of access network. In additional, it introduces several effective ways to realize the high speed low voltage powerline communication by analyzing a powerline channel model. Finally, according to the orthogonal frequency division multiplexing PRinciple, the article describes in detail how to design a high-speed access device based on INT51X1.
