Whether from news reports or social media articles, you may know that 5G is coming.

5G is the 5th generation network. It is a new network(网络)after 1G, 2G, 3G and 4G and it can connect everyone and everything together. 5G networks will cover many cities in China soon. 5G means super-fast data(数据) speed, one can download a two-hour movie for fewer than 10 seconds, and it is making our lives more and more convenient.

5G will make self-driving cars possible. For safety, self-driving cars need super-fast data transmission(传输)to communicate with their nearby environment. 5G is just what makes self-driving cars achieve this. Eyen airplanes will become "smart" in the near future. Passengers will be able to use 5G networks in the air to connect to the Internet or place orders for food and drinks.

5G will be a big help for students who take online classes. Many people live in poor areas in the world where there are no schools. But with 5G, this will change. Students all over the world will be able to see places like the Great Wall without leaving their rooms.

It will be also easier for doctors to treat patients remotely by 5G. It means caring for patients from far away.
