① 2019 marks the first year of the global commercial use of 5G. China is running ahead in this field. In March, 2019, the Shanghai Hongqiao Train Station became world’s first “5G train station”. What’s more, with the technology, it takes only 20 seconds to download a long movie. China is hopeful that we can even experience driver-less cars in daily life soon.

② However, the great technology is still new to most of us. What are the advantages (优势) of 5G? Here are some ideas.

③ It is faster, for sure. It is expected to be at least 10 times faster than 4G. The first 5G modem (猫,调制解调器) of the IT company Qualcomm supports (支持) speeds of up to 5 Gigabytes (千兆字节) per second. Most of us have never experienced anything close to that speed. And we are only talking about the first generation of 5G modems. Future modems are likely to be even faster.

④ But 5G is not all about speed. Have you ever been to a large event where your data (数据) connection slowed down? That is because 4G networks can only support a certain number of devices (设备) per square (平方) meter. 5G networks can do much better. They can support up to a million devices per square kilometer.

⑤ Are you looking forward to that 5G world now? Get ready for the amazing future.
