4G移动通信的特点及关键技术分析

The characteristics and key technologies of 4G mobile communica tion

近年来我国网络通信技术取得了较快的发展,特别是人们对网络通信速度要求不断提升的新形势下,2G和3G通信技术越来越无法满足人们对高水平通信技术的要求,在这种情况下,4G通信技术应运而生。4G通信技术不仅传输效率较为稳定上,而且传播速度非常快捷,具有人性化和智能化的结构,能够更好的为人们提供高水平的通信服务。4G移动通信技术有效的满足了人们对技术更新和功能体验的要求,成为当前移动通信的主流技术。

In recent years,the network communication technology of our country has made rapid development, especially the people of network communication speed requirements continue to increase under the new situation,2G and 3G communication technology and increasingly unable to meet the people＇s requirement of high level communication technology,in this case,4G communication technology arises at the historic moment.4G communication technology not only transmission efficiency is relatively stable,but also the speed of communication is very fast,with the structure of human and intelligent,can better provide high level communication service for people.4G mobile communication technology effectively meet the people＇s requirements for technical updates and functional experience,and become the mainstream of mobile communications technology.
