随着工信部发放4G牌照,我国正式进入4G时代。4G这个词汇越来越频繁地进入人们的视野。不过很多人还在疑惑:4G究竟是什么?对我们意味着什么?全球范围的4G发展如何?1 4G是什么最简单的字面解释是,4G是英文“第四代”的缩写,指在移动通信领域第一代模拟技术、第二代数字技术、第三代以多媒体通信为特征的3G技术之后的第四代移动通信技术。4G最大的特征是高速。根据国际电信联盟的定义,4G技术可以允许用户在静止或步行状态下的传输速率达到每秒1000兆比特,在乘坐汽车或火车等高速移动状态下可以达到每秒100兆比特。与之形成对比的是,现在3G技术的速率通常只有每秒几兆比特。
With the Ministry of Industry and issued a 4G license, China officially entered the 4G era. 4G the word more and more into people’s field of vision. But many are still wondering: What exactly does 4G mean? What does it mean to us? What is 4G worldwide? 1 What is 4G? The simplest literal interpretation is that 4G is an acronym for English, “fourth generation,” meaning The first generation of mobile communication technology in the field of simulation, the second generation of digital technology, the third generation of multimedia communication features 3G technology after the fourth generation of mobile communication technology. The biggest feature of 4G is high speed. According to the definition of the International Telecommunication Union, 4G technology can allow users to transfer data at 1000 megabits per second at rest or walking and up to 100 megabits per second when traveling at high speeds in cars or trains. In contrast, the rate of 3G technology is usually only a few megabits per second.
