电力线通信技术在宽带接入中的应用

APPLICATION IN BROADBAND ACCESS OF PLC

分析了PLC技术的原理和特性,并与其它接入技术进行了比较,结合电力线既传输电能又传输数据的特点,对PLC数据传输技术进行了探讨,高速PLC利用既有电力线,无需重新布线即可组成小区配电变压器供电范围内的宽带接入网,PLC技术可为用户提供高速数据、视频、语音服务,从而形成包括电力在内的"四网合一".

Analyzed the principles and characteristic of PowerLine Communication(PLC), and compared with other access technology. According it's characteristic of transmitting power and data, studied the theory of PLC signal transmit technology. As the high speed PLC uses the intrinsic powerline, we can get a broad band access network within rang of a distribution transformer. PLC can supply every services such as high speed Internet access video VoIP and power, so as to get'four network union'.
