You might have noticed that sometimes, when you're playing mobile games or making a video call, the picture suddenly freezes (卡顿) because the network speed is too slow. When you try to download a movie on your phone, it seems to take forever.
These annoying things will soon become things of the past, as China just issued commercial licenses (发放商业牌照) for 5G networks on June 6. This means that China's telecommunications (电信) companies will be able to offer 5G network speeds for mobile phone users.
The "G" stands for generation (代). 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data and Internet, and 4G made all of these things faster. So what will 5G bring?
First of all, 5G is so fast that it will allow us to download an entire HD movie in a second. The delay (延时) between sending and receiving data will be shortened. Now, 4G takes about 100 to 200 milliseconds (毫秒), while humans have a reaction time of about 200 to 300 milliseconds. But 5G will get the delay down to 1 millisecond or less, which is almost real-time.
Because of this increase in speed, it will possible to create and use new kinds of technology. Robots will be used to do operations because doctors will be able to control them from somewhere else without any delay. Self-driving cars will be able to drive more safely because they can smoothly communicate with other cars, traffic lights and road sensors (传感器). 5G also makes the Internet of Things (IOT, 物联网) possible.
All in all, 5G will shape every type of technology that it touches. And you won't have to wait too long for that to happen.

Once upon a time a little leaf was heard to cry, as leaves often did when a gentle wind passed by. The twig (小枝) asked, "What's the matter, little leaf?" The leaf said, "The wind just told me that one day it will pull me off!" When the tree heard this, it swung all over and promised the leaf, "You will not go till you want to."
The sunny days of the autumn came. The little leaf saw all the leaves around becoming very beautiful. Some were yellow, some were red, and some were in both colors. The little leaf asked the tree what it meant. The tree said, "All these leaves are ready to fly away, and they have put on these beautiful colors because of joy."
The little leaf wanted to go, and grew very beautiful in thinking of it. When it was very bright in color, it saw the branches (树枝) of the tree had no color in them. The leaf asked, "Branches, why are you brown?" "We must keep our working clothes on. Your clothes are for holiday, because your tasks are over," said a branch.
Just then a little puff of wind came, took the leaf up and turned it over and over. The little leaf was like the fire in the air, and fell down silently among hundreds of other leaves. It began to dream — a dream so beautiful that perhaps it would last forever.
