摘　　要：利用遍布城乡的低压电力线作为通信介质构筑高速数据通信网络,为用户提供高速互联网访问、视频点播、IP电话等服务,正日益引起人们的关注。本文介绍了低压高速电力线通信技术的基本技术原理、发展概况和电力信道特点并对不同的通信方式和部分公司的电力线载波产品进行了比较。由于电力信道环境的恶劣和技术不成熟等原因,PLC技术的推广仍存在挑战和困难。The use of existing power lines for transmitting high speed data is particularly interesting since it would provide customers with fast Internet access, telephone services , and video services. In this paper, the basie theory, development, implement and characteristic of low-voltage power line communication are addressed. Furthermore, the main products of power line communication are listed and power line communication is also compared with other communication methods. However, many challenges and difficulties exist in the wide implement because of power line channel's complextiy,technology's limitation ,and so on.
