摘要
以全新的视角,首先从电信设备系统侧指出我们正在经历"无线化"的革命转折,之后从用户侧指出我们正在经历的"移动化"的革命转折。这两个转折是同时发生的,因为人类需要任何应用都要能够满足人与生俱来的"移动性",IT世界技术水平的发展和积累终于达到能够开始全面满足这个基本属性的阶段。这是一个革命性的转变,对无线网络带来五个方面的挑战。
The paper points out that we are going through a revolutionary turning point towards ＂wire- less＂ from infrastrueture point of view and ＂mobi- lization＂ from subscribers＂ point of view. They are occurring at almost the same time because the ICT applieations are to meet the basic feature of human, which is ＂mobile capability＂. There are 5 chal- lenges to the infrastructure network, namely capaci- ty, bandwith, easy-to-use, health and coverage.
