3 . Big telecommunications companies such as Huawei, Samsung and Qualcomm have announced their latest fifth generation (5G) products. They have also announced that 5G technology would be widely used by 2020, causing some experts to say the “5G epoch” is coming. Yet, when reporting about 5G, many reporters only described it as a “much faster” technology than 4G. As a result, what people know about 5G is that they could “download a movie within one second”.
Actually, 5G technology has many more advantages than 4G besides the speed. It can be used for at least two purposes－for connecting everything and removing delays(消除网络延时).
Connecting everything is one of the strongest functions of 5G. It makes the Internet Things possible. Take driverless smart cars as an example. 5G technology can connect all parts of a transportation system including traffic lights, CCTV cameras and cars to build up perfect coordination(协调). In this way, these cars can avoid obstacles(障碍) and move on driving routes, which will help improve self-driving technology.
And removing delays might be useful especially in online games. Even long after 4G technology was introduced, players still worried about losing games because of low speed. This problem can be solved with 5G technology, because it will make sure of continuous high speed.
And for those people who think that 5G costs will be very high, they need not worry. Compared with 4G macro base station, a 5G macro base station can provide service to more users. Factories can produce more macro base stations to allow more people to use. The more users, the lower cost. Therefore, 5G technology won’t cost as much as they thought.

4 . China is running ahead in 5G. In March, 2019, the Shanghai Hongqiao Railway Station became the world's first 5G railway station. Now, it takes only 20 seconds to download a long movie there.
We are moving closer and closer to the 5G world. However, the new technology is still strange to most of us. What is 5G. after all? At first, 5G is fast. 5G will be much faster than today's 5G networks.
The first 5G modem of the IT Company Qualcomm supports speeds of up to 5 gigabytes per second. Most of us have never experienced anything close to that speed. And we are only talking about the first generation of modems. Future models are likely to be even faster.
But 5G is not all about speed. Have you ever been to a large event where your data connection slowed down? That is because 4G networks can only support a certain number of devices per square kilometer. 5G network will be able to do much better. They can support up to a million devices per square kilometer.
Now, you begin to understand why 5G is a huge change over 4G. The technology is not just for the smart-phones. It has a strong influence on every connected device. With 5G, self-driving cars will be able to communicate with the world around them as quickly as possible, Wearables, PCs and smart home devices will be able to improve as well.
Are you looking forward to that 5G world now?

5 . Have you heard of 5G ? It is the fifth generations (代) of mobile network technology (移动网路术) .These new networks are coming.
China just issued commercial license(发放商用牌照) for 5G . This means that China’s telecom(中国电信) companies will soon be able to offer SG networks for mobile phone users.
Each mobile network generation is faster and more powerful than the one before it . IG let us talk to each other. 2G let us send messages. 3G gave us data (数据) and the internet. And 4G made all of these things faster. What's special about 5G?
5G has a very short delay (延时) between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds(毫秒) to send and receive data . But 5G will get it down to I millisecond. This big change will not only make our mobile internet faster. It will also deeply change our lives.
5G networks are about 100 times faster than 4G. This means you can download (下载) a movie in seconds. 5G will also bring us safer self—driving cars . These cars can send signals(信号)10 each other. 5G will allow cars to react(反应) even faster than real drivers.
Chinese tech company Huawei has me patents (专利)for 5G than any other company in the world. You will need to buy a new mobile phone to use 5G networks . 5G phones cost about 8,000 yuan right now. But experts (专家) say that about one and a half years from now, the price could go down to around 2,000 yuan .

We are moving closer and closer to the 5G world. However, the new technology is still strange to most of us. What is 5G, after all? At first, 5G is fast. 5G will be much faster than today's 4G networks!
The first 5G modem（猫，调制解调器）of the IT company Qualcomm supports 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（一代）of 5G modems, Future models are likely to be even faster.
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(设置) per square meter. 5G networks will be able to do much better. They can support up to a million devices(设置) per square kilometer.
Now, you begin to understand why 5G is a huge change over 4G. The technology is not Just for the smartphones. It has a strong influence(影响) on every connected device.

7 . Chinese companies lead in global 5G patent applications (专利应用 ) with Huawei taking the crown, according to a report Ly Iplytic, an authorized patent data company. Three companies from China were included in the top 10 list of 5G Standards-Essential Patents(SEPs) family owners. Huawei rainked first. ZET Corp. and China Academy of Telecommunications Technology ( CATT) grabbed fifth and ninth places, respectively.
Chinese companies topped the list for most 5G SEPs applications in communication systems by the end of April 2019, accounting for 34 percent of the world’s total. Chinese tech giant Huawei has taken a leading role by owning 15 percent of SEPs, according to the report Who Is Leading the 5G Patent Race?
5G SEPs are patents that any company will have to use when carrying out 5G technology and no one can avoid them.
Different from 3G and 4G technologies, 5G technology will influence various industries and encourage the appearance of many new products, services and industries.
The automotive sector will most likely be one of the first industries to depend on 5G, which will connect vehicles to other vehicles, roadsides, traffic lights, buildings and the Internet, according to the report.
“It is 5G that is going to be a huge jump forward for communication systems because only with 5G’s higher bandwidth can a number of applications be more advanced(尖端的) and used by most consumers.” Said Niclole Peng, senior director of the market research company Canalys.
As 5G technology has combined various industries and technologies, the number of 5G SEPS rose to more than 60,000 globally by the end of April 2019, the report said.
