Do you know 5G? It is the fifth generation (代) of mobile network technology. These new networks are coming.

China just issued commercial licenses (发放商用牌照) for 5G on June 6. This means that China's telecom companies were soon able to offer 5G networks for mobile phone users.

Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data and the Internet. And 4G made all of these things faster. What's special about 5G?

5G has a very short delay between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds (毫秒) to send and receive data. But 5G will get it down to 1 millisecond or less—this is almost real-time.

This big change will not only make our mobile Internet faster, but also deeply change our lives. Read on to find out how.

5G+entertainment (娱乐)

5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G.

Also, virtual reality (VR) games will become more popular with 5G. The short delay of 5G will make the games feel even more real.

5G+transportation

5G will also bring us safer self-driving cars. These cars can send signals (信号)to each other. They also talk to traffic lights and road sensors (传感器). 5G will allow cars to react even faster than human drivers.

5G+smart homes

5G also makes the Internet of things possible. Internet of things is a large network that connects everything to the Internet. Smart homes are part of it.

For example, your toaster can automatically (自动地)start making breakfast after your alarm rings. And if its sensor feels the air becoming dry, a smart sprinkler could water your plants by itself.
