During to the migration of networking technologies and the cost reduction of semiconductor devices, many of the networking applications had been developed and discovered. However, the cost of human resources and the issues of the last mile in the communication networks still remained as obstacles to slow down the developing of the communication world. So, in addition to the existing communication media and technologies in the last mile such as the telephone line, fiber, or wireless, the technologies using the most widespread power line to carry voice and data had become more and more interested. This paper was focused on the developing status of the power line communication technologies worldwide and was especially focused on the issues of the access broadband power line technologies. We hope that through the discuss of the features and advantages and disadvantages of the broadband power line technologies could give us some references for our future communication network planning.
