电力线宽带通信国际标准技术分析与比较

目前,国际上存在2种支持电力线宽带通信标准体系:IEEE 1901和ITU-T G.hn,二者分别定义了不同电力线通信的物理层和介质访问控制层的技术规范.为了更深入的了解电力线国际标准性能上的优劣势,文章对两大标准体系的物理层和介质访问控制层技术进行整体概述,采用自上而下的方法分析两大标准体系的技术特点.并对IEEE 1901和ITU -TG.hn进行了对比,最终分析了两大标准达到互联互通的发展趋势和产品共存性问题.

Analysis and Comparison on the International Standards of Broadband Power Line Communication Technology

Power line communication is becoming more and more common for high-speed communication,while at the same time the reliability of power line communication faces many challenges.Currently,there are two international standard systems for power line communication: IEEE 1901 from the Institute of Electrical and Electronics Engineers and ITU-T G.hn from the International Telecommunication Union.They both address the medium access control and the physical layer specifications of power line communication.This article summarizes the media access control and the physical layer technology of the two standards.A top-down approach was used to analyze the technical features of the two standards.The similarities and differences between the IEEE 1901 and ITU-T G.hn standards are compared,as well as the potential performance issues.Finally,this article analyzes the interconnected development trend of these two standards and their product coexistence issues.
