Take a look at your parents’ mobile phone. Can you see a small “5G” at the top? Do you know what is it? 5G means “5th generation mobile network (第五代移动通信技术)”.
Each mobile network generation is faster and more powerful (有力的) than the one before it. In 1980s, with 1G, we made phone calls for the first time. Around ten years later, 2G let us send messages. Then in 2000s, using the Internet, listening to music and sending emails appeared in people’s life for 3G. Later, we could watch films and even buy things in 2010s with 4G. To our surprise, 5G is coming now. What’s special about 5G?
Do you have online classes at home? With 5G, you can have classes outside your home. The class can go as well as the ones you have at home. Students from poor areas (地区) can have the chance to study just like you do.
In some movies, you might see cars that can drive by themselves—you tell them where you want to go, and they take you there as fast as possible. With 5G, cars like this may appear in our life. It makes self-driving cars safer. These cars can send messages to each other. They can also “talk” to traffic lights. 5G will make cars move even faster than human drivers.
5G networks are about 100 times faster than 4G. This means you can download (下载) a movie in seconds using 5G, and makes your video calls clearer. What’s more, VR games will become more popular with 5G. It will make the games feel even more real.
All in all, 5G will change the way people live and make our life more comfortable and convenient (方便的) than ever before. You won’t have to wait too long to enjoy it. Now you can buy a new mobile phone to use 5G networks. 5G phone cost 8,000 yuan right now. But experts say that about one and a half years later, the price could go down to around 2,000 yuan.
