3G风潮还没过去,4G似乎就已经到来了。4G是第四代移动通信及其技术的简称,融合LTE、WiMAX以及“演进的3G技术”为一体,能够传输高质量视频图像,以及图像传输质量与高清晰度电视不相上下的技术产品。4G系统能够以100Mbps的速度下载,比拨号上网快2000倍,上传的速度也能达到20Mbps,并能够满足几乎所有用户对无线服务的要求。它将构造出一个比3G通信更完美的新无线
3G wave has not passed, 4G seems to have arrived. 4G is the abbreviation of the fourth generation of mobile communication and its technology. It integrates LTE, WiMAX and “Evolved 3G technology”, and is capable of transmitting high-quality video images and achieving the same image transmission quality as high-definition television product. 4G system can download at a speed of 100Mbps, which is 2000 times faster than dial-up and upload speeds up to 20Mbps, and can meet the requirements of almost all users for wireless services. It will create a new wireless that is more perfect than 3G communication
