专题28 5G技术

一、阅读单选。

（2022·陕西宝鸡·一模）Whether from news reports or social media articles, you may know that 5G is coming.

5G is the 5th generation network. It is a new network after 1G, 2G, 3G and 4G. It can connect everyone and everything together. 5G networks will cover many cities in China soon. 5G means super-fast data speed. One can download a two-hour movie for fewer than 10 seconds, and it is making our lives more and more convenient.

5G will make self-driving cars possible. For safety, self-driving cars need super-fast data transmission (传输) to communicate with their nearby environment. 5G is just what makes self-driving cars achieve this. Even airplanes will become “smart” in the near future. Passengers will be able to use 5G networks in the air to connect to the Internet and can order for food and drinks.

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 any more. Now let’s get ready to say goodbye to 4G and welcome the coming of 5G.

When visitors to the Palace Museum feel a need to sit down for a cup of tea or find a bathroom without a long line, they soon will be able to turn to their smart phones for the information they need.

This modern solution comes thanks to an agreement signed on Friday by the museum and Huawei Co., the telecommunication giant, to build a “smart network” using 5G technology. Under the agreement, 5G Wi-Fi signals will cover the Palace Museum, China’s royal palace from 1420 to 1911.

“It’s important to always stay close to the latest technology to better serve the public,” said Shan Jixiang, former director of the Palace Museum. Shan said there is still much room for improvement in the handling of a huge number of cultural relics,such as when the priceless painting “Along the River During the Qingming Festival” is exhibited again in the future. When it was last exhibited in 2015, visitors stood in long lines until 3 am to have a look. The museum ended up preparing fast food to serve the hungry visitors. “I don’t want that scenario to happen again,” Shan said. “Our operation can be done in a more scientific way.

The new system will also make use of the closed-cameras that are set up all over the Palace Museum to safeguard the museum’s precious relics. More than 1.86 million of them are housed at the museum, which recorded nearly 20 million visits from the public last year. “How can we make sure no single visitor who might have evil ideas threatens these treasures?” Shan said. “After adopting the internet of things, we can instantly detect any motion involving the relics to prevent such threats.”

The 5G network also will be used to improve remote meeting through webcams, which will discuss with scholars to jointly find the best answers for repair and store issues.
