If you look at the top of your phone, you will usually see a little symbol that says 3G or 4G. The G means “generation” of your mobile network. But these symbols will become things of the past after 5G networks fully arrive.

On March 30,2019, Shanghai vice-mayor (副市长) Wu Qing made the first 5g video call on the Huawei Mate X Smartphone. Shanghai has also become the first city in our country to start testing 5G networks.

More and more people started to learn about 5G because it has many advantages.

5G will let people download and upload the data (上传数据) faster than before.

People can use it for many other things as well. For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars take time to send the information and the receiving instructions. They can’t react (反应) in time. With the help of 5G, this can be greatly improved.

People could also use 5G to power the Internet of Things (IOT物联网). It’s a large online network that connects all things and people. Fast Internet speed will be the key to developing this technology.

5G is on the way. It will lead us to a new world. Are you ready?
