On the morning of May 30th, 2019, Huawei helped the BBC use 5G to report news. It was the first time that 5G was used in the world! Actually, China just began to use 5G in June 2019. What’s the most special about 5G? 5G lets us send and receive information in a very short time. Now, it takes about 100 to 200 milliseconds(毫秒) to send and receive information by using 4G. But 5G will help reduce the time to 1 millisecond or less. The big change that 5G brings will not only make our mobile network faster, but also deeply change our lives in many ways.
First, 5G can connect with amusements. 5G is about 100 times faster than 4G. This means you can download a movie in seconds by using 5C. Also, VR games will become more popular with 5G. 5G will make people feel the games become even more real.
Second, 5G can connect with traffic. 5G will also make self-driving cars safer. These cars can send messages to each other. They also “talk” to traffic lights and road sensors(传感器).5G will allow self-driving cars to have faster reaction(反应) than human drivers.
Third, 5G can connect with smart homes. 5G also makes IOT possible. IOT is a large network that connects everything to the Internet. Smart homes are part of it. Smart homes can make the machines automatic. For example, if the sensor feels the air becoming dry, a smart sprinkler(洒水器) could water your plants by itself. And your toaster could start making breakfast ahead of time or before you get up.
Although not everyone can use 5G networks now, China is trying its best to let everyone use 5G as soon as possible!
