So rapidly does the technology develop that no one can predict what may happen tomorrow. The number of 5G users in China has reached 20 percent, which leaves the people in the world
High—quality 5G networks
Huawei has already employed low—carbon strategics in more than 100 countries, including Saudi Arabia, Greece, Pakistan and Switzerland,
2 . Cars could soon be communicating with each other using 5G to make drivers aware of upcoming hazards (危险), scientists claim. The extremely fast mobile internet would allow for rapid information transmission and could make drivers aware of black ice, pot holes or other dangers up ahead.
Several car manufacturers are already integrating 5G into their vehicles, including as a tool to help serve in the generation of sel-driving vehicles.
Experts at Glasgow Caledonian University (GCU) believe the high-speed connection will also improve the reliability and capability of automated vehicles to the point where they will be safer than the manual cars being driven today. They predict the number of road traffic accidents, which according to the World Health Organization account for more than 1.3 million deaths and up to 50million people injured worldwide every year, will drop drastically (彻底地) as a result.
Dr Dimitrios Liarokapis, a member of the research group, said, “To have a better idea of what the future will look like, think of having such cars that not only use sensors to scan what's around them, they can also talk to each other and exchange safety-related information about their surroundings over an area that covers several square miles. With the help of 5G, a vehicle-generated early warning system that reminds drivers is possible within the next few years. Cars that are close enough to the danger area will transmit warning messages to other cars around them using short-range communication technologies, but also to cars further away using 5G, fast and reliably.”
A few manufacturers are already working on connected cars. Of them, Ford revealed its intention to fit 80 percent of its 2020 vehicles with technology that warns drivers about upcoming road accidents, bad weather and traffic jams.

3 . We have heard some interesting ways that 5G wireless(无线的) technology might change our lives in the future.
5G technology promises the internet speeds between 50 to 100 times faster than 4G systems. While 5G is set to be used in some limited areas of America this year, much of the world is not expected to receive widely used service until 2023.
One project in Britain, however, is already testing this super fast technology on an unlikely group Internet users—cows. The project was developed by American technology company Cisco Systems, Inc. It also receives money from the British government. Cisco says the program seeks to explore the future of 5G in countryside areas around the world.
Testing areas were set up at farms in 3 countryside areas of England. The cows are equipped with 5G devices(装置)that connect to a robotic milking(挤奶) system,which uses sensors(传感器) and machine learning to fully automate the process. System designers say technology takes over after a cow feels ready to be milked and walks towards an automatic gate. During the milking, machines give food for the cow as a reward.
Other 5G technology tools include automated brushes that turn on when the cow rubs up(蹭) against them. Sensors also control the amount of light to the cows living areas depending on the weather. And, an automatic feeding system makes sure the animals always have enough to eat.
Duncan Forbes, head of a government-funded agricultural engineering organization, told Reauters that the project shows the farm’s cow operation can be greatly improved with 5G technology and that the experiment provided strong evidence that 5G technology can be widely used in the future, not just on farms in Britain,but in countryside across the world.
