电力线接入技术与接入网的发展

Power line access technique and AN's development

随着IP业务的急剧增长 ,接入网已成为全网带宽的最后瓶颈 ,宽带化和IP化将成为接入网发展的大趋势。论文从有线接入和无线接入两方面出发 ,对现有的接入方式进行了详细的分析和比较 ,还论述了有线接入和无线接入的各种方式。其中 ,尤其对电力线接入等技术作了详细的介绍 ,并指出了接入网的发展前景。

With the development of IP services,AN(Access Network)is now the ultimate bottleneck of the bandwidth of overall telecom network,and the development of a broadband and IP based access network has become the general trend of access network development.This paper involved many wired and wireless AN technologies.Among these,DPLC(digital power line carrier)access,Ethernet access,LMDS access,wireless WDM access are explained in detail.In additional,in this paper,we point out the AN's developing tendency.
