=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 fully arrives．
On March 30th，2019，Shanghai vice﹣mayor Wu Qing made the first 5G video call on a Huawei Mate X smartphone，CGTN reported．Shanghai has also become the first city in China to start testing 5G networks．
Now，4G takes about 100 to 200 milliseconds（毫秒）to send and receive data（数据）．But 5G will get it down to 1 millisecond or less．This big change will not only make our mobile Internet faster．It can be used in many other ways 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 this information to a data center and receives instructions．However，it takes time to send and receive this information．With this kind of lag，the cars might crash（撞击）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）．This refers to a large online network that connects all things and people．Fast Internet speeds will be the key to developing this technology．For example，with IOT under 5G，your refrigerator could automatically（自动地）place an order online for eggs when it finds that there are no eggs left inside．
All in all，5G will shape every type of technology that it touches．And you won't have to wait too long for that to happen．
