1 . What is 5G? It is the fifth generation of mobile network technology. China’s telecom companies has been able to offer 5G networks for mobile phone users since 2019.
Do you know the development of mobile network technology? 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 (延迟) 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 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+transport 5G will also bring us safer self-driving cars. These cars can send signals 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 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.

2 . If you look at the top of your phone, you’ll usually see a little symbol that says 3G or 4G. The “G” stands for the “generation” of your mobile network. But these symbols will become things of the past after 5G networks fully arrive.
On March 30th, 2019, Shanghai vice-mayor（副市长）Wu Qing made the first 5G video call on a Huawei Mate X smart phone, CGTN reported. Shanghai has also become the first city in China to start testing 5G metworks.
About 100 times faster than 4G networks. 5G will let people download and upload data faster than ever before. But 5G won’t just bring faster mobile Internet. 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 have one problem—lag. When the car “sees” an obstacle（障碍物）, it sends the information to a data center and receives instructions. However, it takes time to send and receive information. With this kind of lag, the cars might crash because they don’t receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer, according to CNN.
5G could also be used to power the Internet of Things（IoT 物联网）. This refers to a large online network that connects all things and people. Fast Internet speeds will be the key to develop this technology.
The IoT could be used in a lot of ways. For example, with IoT, your refrigerator could automatically（自动地）place an order online for eggs when it finds that there are no eggs left inside. What happened to the swallow at last?

In 1987, Huawei was started in Shenzhen. 30 years later, the company has now beaten Apple and become the world’s second-largest maker of smartphones behind Korea’s Samsung. It has also become the world’s largest supplier(供应商) of 5G.
Recently Huawei faced some difficulties. The U.S. government ordered a ban(禁令) on its sales in America. American officials said Huawei gave information that it collected to the Chinese government. The U.S. government planned to stop selling parts and services to Huawei, which was believed that Huawei’s business would be hurt.
“We have never received such a request from the Chinese government and we have never tried to get into other systems to collect information.” Ren Zhengfei, Huawei’s founder and president said. “The ban from the U.S. would have little effect on our company. Huawei has enough ability to deal with the problems.” Ren added.
Facing the ban of the U.S., Huawei is growing. Huawei’s smartphone sales around the world rose 50 percent compared to a year earlier in the first three months of 2019. So far. Huawei has grown into the world’s largest telecommunication equipment(电信设备) supplier, selling in 170 countries. It may beat Samsung as the largest smartphone maker in the near future.
