4G速度真有那么快吗或许4G在人们的眼里只是很抽象的概念,只知道比3G高级、比3G快。那么什么是真正的4G网络呢?简单说来,4G就是在经历GSM、GPRS、3G之后的第四代移动网络通信技术。与上一代3G相比,4G有技术先进、传输速率高、频率使用经济等特点。而对于普通用户来说,最直观的感受是“快”!按中国移动的广告,4G网络的最大下行速度可以达到100M/S,这意味着不到一秒钟便可下载一首MP3音乐,一部1G大小的电影1分30秒就能下载完成。几乎超越了普通传统固网宽带的速度,真正摆脱了线缆的烦恼,实现了随时随地随身宽带上网的畅爽之感。而事实上,由于基站覆盖、网络设备等各种因素的影响,这样的速度只是理论值,在目前的实际使用中几乎不可能达到。王先生告诉记者,在北京使用4G近一个月的时间里,最高下行
4G speed is so fast? Maybe 4G in the eyes of people is just a very abstract concept, only know than 3G advanced faster than 3G. So what is the real 4G network? In short, 4G is the fourth generation of mobile network communication technology after experiencing GSM, GPRS and 3G. Compared with the previous generation of 3G, 4G has advanced technology, high transmission rate, the use of economic frequency and so on. For ordinary users, the most intuitive feeling is “fast ”! According to China Mobile’s advertising, 4G network maximum downlink speed can reach 100M / S, which means less than one second to download an MP3 Music, a 1G-sized movie 1 minute 30 seconds can download completed. Almost beyond the speed of ordinary traditional fixed-line broadband, cable really get rid of the troubles, to achieve anytime, anywhere with a smooth broadband Internet access feeling. In fact, due to the influence of various factors such as base station coverage and network equipment, such speed is only a theoretical value and is hardly achievable in the current actual use. Mr. Wang told reporters that in Beijing using 4G nearly a month’s time, the highest down
