5G is becoming more and more popular these days. 1. The first 5G video call was made on a Huawei Mate X phone on March 30, 2019, CGTN reported.

Shanghai is the first city in China to start a test run of 5G networks. About 100 times faster than 4G networks, 5G will allow people to download and upload(上傳) things faster than ever. 2. Self-driving cars may be one of the biggest changes. 3. When the car sees an obstacle(障礙), it sends this information to a data center and waits for instructions. 4. 5G networks will reduce the time it takes and make the cars safer, CNN noted.

5. This refers to a much larger online network that connects everything and everyone. Very fast Internet speeds are the key to realizing it.

Meanwhile, China’s first 5G police station was recently shown in Bao’an district in Shenzhen. China Mobile Communication Corporation(CMCC) made Xiamen’s first 5G video call on April 27, 2019, bringing the city into the time of 5G.
