从电报、电话到手机，从1G到4G，通信技术为人类和社会带来了无尽的便利和福祉。如今我们正迎来全新的5G时代。
5G不是横空出世个令人惊异的新技术，5G技术是现有技术的新组合，是4G技术的再演进。在3G、4G和5G等名词中，G是英文单词“generation”（第x代）的缩写。因此，5G就是第五代移动通信技术。
5G是一场融合创新。5G超高速上网和万物互联将产生呈指数级上升的海量数据，这些数据需要云存储和云计算，并通过大数据分析和人工智能产出价值。而融合于未来网络的大数据、云计算、人工智能等技术又将如何推动这场网络创新？值得期待。
China is working furiously to be the first in the world, to have a nationwide 5G network.
Right now, it holds a narrow lead over South Korea, the US and Japan.
5G-the fifth generation of cellular mobile communications -promises a lot more than the fastest internet speed.
It will allow devices to communicate with virtually zero lag time.
That would pave the way for cutting-edge advances.
Imagine a surgeon performing an operation, using a virtual reality headset and a special glove. . .
And the patient, who is actually on the other side of the country, being operated on by a robotic arm that moves in harmony with the surgeon's hand inside that special glove.
5G could also enable the wide adoption of a new generation of self-driving cars.
It would connect autonomous vehicles in a way where they could talk to one another.
It would also link a network of sensors built around a city, so that these cars would be able to drive around without bumping into other vehicles or hitting people.
