What is 5G? It is the fifth generation of mobile network technology. In the past, 1G let us talk with each other. 2G let us send messages. 3G gave us the Internet. And 4G made all of these things faster. What's special about 5G?

    5G + entertainment

    5G networks are about 10 times faster than 4G. This means you can download a movie in seconds using 5G. Also, VR games will become more popular with 5G. 5G will make the VR games even more real.

    5G + smart home

    5G also makes the Internet of Things(物联网)possible.Smart home is part of it.For example,your bread maker could make breakfast by itself after your alarm rings. And if the air in your room is too dry, a smart sprinkler could water your plants by itself when you are not at home.

    So you just need to buy a new mobile phone to use 5G. But a 5G phone costs about 8,000 yuan right now. It is said that about one year from now, the price could go down to around 2,000 yuan.
