中国宽带网建设的一些特点

SOME CHARACTERISTICS IN CHINABROADBAND NETWORK CONSTRUCTION

本文从我国人均GDP水平低而城市人口密集、电信网规模世界第一但普及率仍低于世界平均水平、宽带网的建设处在窄带网仍然有很大发展空间的时机、无线接入面临电信运营业改革重组后竞争新格局的机遇等国情出发,由七个方面说明中国宽带网建设的特点,指出中国光纤到路边(或大楼、小区)应用的发展走在世界前列,网络设施为宽带化打下了基础,无线频谱和IP地址资源的紧张为3G和IPv6的使用创造了需求,而宽带网的成功则期待开发出适合国情的业务与应用。

Starting from the national conditions of the GDP level is low, the cities and towns are densely populated,the telecom network scale ranks first in the world but the teledensity is still less than the average level of theworld, the construction of the broadband network starts in a time when the capacity of the narrowband net-work still has a large space for development and the wireless access is facing the opportunity of new compe-tition situation that appears after the telecom restructuring, this paper discusses some characteristics fromseven aspects in China's broadband network construction and indicates that China's development of the FTTC(or FTTB, FTTZ) can be said to be among the world's forerunners, the network infrastructure has laid founda-tion for the broadbandization, the tense situation with the radio frequency spectrum and IP address resourceshave set demands for the applications of the 3G and IPv6, and the success of the broadband is looking forwardservices and applications which will accommodate the actual conditions of the country.
