5g的英文介绍及前景展望怎么写(5g的英文介绍及前景展望作文)

话说，从3G和4G开始，我们对这种起名方法就已经不陌生了。不过，大家都知道这个G到底是什么意思吗?3G、4G、5G又分别是什么呢?今天就让小编来科普一下这个吧~

首先，这个 G 代表的是Generation(一代)5G 的全称是 5th generation mobile networks，也就是“第五代移动网络”。然后，5G 和 4G 相比，除了速度更快以外，它还能容纳更大的用户密度(user density)换句话说，扎堆上网拖网速的现象会减轻很多。而且它支持一种叫“设备到设备通讯”的技术：Device-to-Device Communication(D2D)3G、4G网络里，所有的设备之间，如果要传递信号，这些信号都需要经过中转站。而 5G 里面则可以通过这种 D2D 技术直接传，这也是它的速度得以进一步提升的原因之一。

Why do we need 5G?

Mobile communication has profoundly changed people's life, but people's pursuit for higher performance of mobile communication has never stopped.

In order to cope with the future of mobile data traffic explosive growth, the connection of massive device, the continuous emergence of various new services and applications scene, the fifth generation mobile communication (5G) system will emerge as times require.

The necessity of 5G

Why does the vision of 5G emerge?

5G will make information break through the limitation of time and space, providing excellent interactive experience and immersive information feast for the user. Through the seamless fusion way, 5G will close the distance of all things, realize the intelligent interconnection between man and all things on earth.

5G will provide the access rate of fiber like, the using experience of “zero delay”, the ability to connect billions of devices, super high flux density, super high connection number density , super high mobility and other multi scene favorable service and intelligent optimization of business and user perception. At the same time, 5G will bring the network over a hundred times the energy efficiency and ultra hundred times the bit cost reduction. Finally 5G will realize the general hope of “Get the information whenever you want and all things on earth are at your fingertips”.
