The Beijing 2022 Olympic Winter Games has given the best experience for TV viewers(观众) around the world.
"With the help of 5G and cloud technologies, viewers will be able to enjoy the world's clearest broadcast, an 8K broadcast in ultra-high definition(超高清晰度), from TV sets in their homes," said Yu Hong, head of the technical department of the Beijing 2022 Organizing Committee.
At Wukesong Sports Center, many cameras are set up around the venue(场馆). They can shoot(拍摄) competitions from different angles at the same time. Using a phone app, viewers can choose different viewing angles to watch the events. 5G technology is widely used at the games. More than 100 5G base stations have been set up. They give 5G signals(信号) in and around all of the Olympic venues.
The highways and railways between the Beijing and Zhangjiakou competition zones also have full 5G coverage. The 5G network can stand high winds and cold temperatures, down to—45 ℃. According to China News Service, 5G networks even bring the Beijing Winter Games to Qomolangma(珠穆朗玛峰). 5G towers to broadcast the Beijing Winter Games are set up around the mountain. People are able to watch live broadcast of the Games from the top of the world.

Do you know 5G? It is the fifth generation (代) of mobile network technology. These new networks are coming.
China just issued commercial licenses (发放商用牌照) for 5G on June 6, 2019. This means that China's telecom companies will be able to offer 5G networks for mobile phone users.
Each mobile network generation is faster and more powerful than the one before it. 1G 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 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 1 millisecond or less-this is almost real-time.
'This big change will not only make our mobile Internet faster，but also deeply change our lives. Read on to find out how.
5G + entertainment (娱乐)
5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G.
Also, virtual reality (VR) games will become more popular with 5G. The short delay of 5G will make the games feel even more real.
5G + transport
5C will also bring us safer self-driving cars. These cars can send signals (信号) to each other. They also talk to traffic lights and road sensors (传感器). 5G will allow cars to react (反应）even faster than human drivers.
5G + smart homes
5G also makes the Internet of things possible. Internet of things is a large network that connects everything to the Internet. Smart homes are part of it.
For example, your toaster can automatically (自动地) start making breakfast after your alarm rings. And if its sensor feels the air becoming dry, a smart sprinkler (洒水器) could water your plants by itself.
Your Internet experience is ruined when the net speed is too slow—it takes so long to open a web page and the show you're watching stops every few minutes. That can be very boring. But it could be a thing of the past. China's major telecom carriers（电信运营商）will start to provide 5G services in China.
The "G" in 5G refers to the generations of mobile technologies. 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data（数据）and the Internet, and 4G made all of these things faster.
Now 5G promises much faster speed, and more stable（稳定的）connections. This means that you will be able to download（下载）an entire HD movie in seconds and only experience a short delay（延迟）between sending and receiving data.
According to the Straits Times, 5G will be able to improve many advanced technologies. With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to communicate in real time and avoid probable dangers. Meanwhile, 5G-enabled wearable products will keep doctors in touch with their patients and warn them immediately if there's something wrong. Besides, VR games will become more popular with 5G. The short delay of 5G will make games feel even more real.
But 5G is not perfect. For one thing, 5G will not "travel" far. On 4G networks, you can be 10 kilometers away from the nearest transmission base（传输基地）. But 5G will only cover about 300 meters, meaning that we will need more transmission bases so that we can get signals. And in order to use 5G, we have to buy new products specifically designed for 5G that are expensive now.
If you look at the top of your phone, you'll usually see a small symbol that shows 3G or 4G. The "G" means the "generation(代)" of your mobile network. But they will become history after 5G network fully arrives.
In recent years, China makes great achievement in 5G network. Now it's making efforts to popularize the business use of 5G. Shanghai is the first city in China to start testing 5G networks. On March 30, 2019, Wu Qing, one of the leaders of Shanghai, made the first 5G video call with Huawei Mate Smartphone.
5G allows people download and upload data faster than ever before. It is 100 times faster than 4G mobile network. But 5G doesn't just bring faster mobile Internet. People can use it for many other things as well. For example, 5G can make self-driving cars safer.
Today's self-driving cars have one problem—time lag(滞后). When a self-driving car "sees" an obstacle(障碍物), it sends this information to data center and receives instructions. However, it takes time to do that. That's the time lag. With this kind of lag, the car might have an accident because it doesn't receive instructions in time. But with 5G, the self-driving car can receive instructions more quickly.
5G can 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, your smart fridge could order eggs online when it notices that there are no eggs left inside.
Shanghai Hongqiao Railway Station became the first railway station built upon the 5G digital(数码的) indoor system after China Mobile Shanghai and Huawei started the network's deployment(部署)there on Monday. The move aims to achieve deep indoor 5G coverage within the whole station by the end of 2049. Shanghai Hongqiao Railway Station is one of Asia's biggest traffic centers. It deals with over 60 million passengers every year, with over 330, 000 people passing through each day during the Spring Festival.
5G network is not the same as the network we use now. The 5G network promised faster speed, low latency (延缓), when connecting to the network. For example, you can download a 2GB high-definition(高清) film in less than 20 seconds. More importantly, 5G will help us build the Internet of things (IoT). IoT refers to everyday things being connected to the Internet. People can control their things even they are not near the things. On a summer day, you can turn on your air-conditioner before you go home.
5G network in the railway station will help the station become more energetic and smarter. The passengers will be able to enjoy watching TV on their phones for free as they wait, and take their train. And they will enjoy the robot service and communicate with robots. 5G will really make the station different and it is sure to change people's life.
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 4G 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 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 connection slowed down? That is because 4G networks can only support a certain number of devices per square kilometer. 5G networks 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?
Whether from news reports or social media articles, you may know that 5G is coming.

5G will be a big help for students who take online classes. Many people live in poor areas in the world where there are no schools. But with 5G, this will change. Students all over the world will be able to see places like the Great Wall without leaving their rooms.
It will be also easier for doctors to treat patients remotely by 5G. It means caring for patients from far away.
The facts listed above are only a part of what 5G will make possible and popular. Just as in the early days of the Internet in the 1990s, few could see how it could change our life and the world. The same will surely be true of 5G. With 5G, many things do not seem like dreams anymore. Now let's get ready to say goodbye to 4G and welcome the coming of 5G.
