If you look at the top of your phone, you’ll usually see a little symbol that says 3G or 4G.1. But these symbols will become things of the past after 5G networks fully arrive.
On March 30, 2019, Shanghai vice mayor Wu Qing made the first 5G video call on a Huawei Mate X Smartphone.2.
About 100 times faster than 4G networks, 5G will let people download(下载) and upload data (数据) faster than ever before. But 5G won’t just bring faster mobile internet.3.
For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars have one problem—lag(延迟). When the car “sees” an obstacle(障碍物), it sends this information to a data center and receives instructions.4.With this kind of lag, the cars might hit each other because they don’t receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer.
5G could also be used to help the internet of things(IoT). IoT is a large online network that connects all things and people. Fast internet speeds will be the key to developing this technology. 5.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.
A.Shanghai has also become the first city in China to start testing 5G networks.
B.5G will help us buy eggs quickly.
C.People can use it for many other things as well.
D.However, it takes time to send and receive this information.
E.The “G” is the “generation(代)” of your mobile network.
F.The IoT could be used in a lot of ways.
G.5G networks are much faster than 4G or 3G.
