In 2014, major countries around the world entered the 4G era one after another. People are using smartphones. APP has become a part of people's lives.

If you want to eat, you can poke for takeaway international, and all kinds of delicacies will be delivered to your designated place in a short time.

If you want to take a car, you can poke Tick International, and various models will pick you up at the location you are located to take you to the destination.

If you want to chase dramas, you can poke Film and Television International, a large number of movies, dramas, anime, and documentaries are at your fingertips.

If you want to shop, you can poke Xuanbao International, clothing, 3C, snacks, kitchen and bathroom... The whole nine yards.

If you want to socialize, just poke Youxin International, send texts, pictures, videos, and talk about what you want.

If you want to pay, you can poke and pay with peace of mind, even if you don't bring a wallet or a bank card, you can easily scan the code for electronic payment.

4G has revolutionized the way people live. Life has become simpler, the pace is faster, there is more content, there are more scenes, and the distance is closer, and the ball is becoming more and more like a ball village.

Technology never stops when we start using 4G extensively. R&D institutions must be carrying out the next generation of iterative upgrades. 5G is getting closer and closer.

There are also frequent successes on various scientific and technological fronts. Loongson International has achieved 7nm chip manufacturing.

Hua Wei has completed the design of the Internet of Things chip.

Longguo cloud computing centers, cloud storage, and big data centers are blooming everywhere. It can fully support multi-node content distribution without network congestion.

The basic conditions for 5G are becoming more and more mature, and it is time to establish a 5G demonstration area.

After the Spring Festival, Zhaohui called Zhu Weihua and Qiao Gang Leader together.

"You've finally thought of us." Zhu Weihua quipped as soon as he saw Zhaohui.

"I don't bother you, I want to give you plenty of time. I guess you're holding back a lot of good stuff right now. Zhaohui said.

"In the 5G era, smart phones can only be a part of it, and more will be the common intelligence of various application equipment and facilities and home terminals." Qiao Gang Leader also said.

"Is the standard for 5G developed?" Zhaohui asked with concern.

"It's been formulated, it's called IMT60, and this year is the 60th anniversary of the National Day, so I'll call it IMT60." Zhu Weihua said.

"You elaborate on the application standards of 5G." Zhaohui said.

Then Zhu Weihua introduced the 5G standard formulated by Huawei Company to Zhaohui in detail.

The first is high transmission. In other words, the transmission rate of 5G is at least 1,000 times higher than that of 4G. The rate of transmission reaches 20G per second.

In 3G, we upload and download in terms of how many K. When it comes to 4G, we all calculate in M. 4G is almost 1,000 times faster than 3G. After all, 1M = 1024K.

Then in the 5G era, it will be measured according to G. 1G=1024M。 In the past, when we downloaded a high-definition movie, it took several gigabytes and several minutes to download. Now download several G movies mainly in 1 second. 5G has brought people into the era of "second-in-seconds".

Zhaohui is very satisfied with the download speed of 5G. That is, in the future, the waiting time for downloads is almost non-existent. In that way, people's happiness in using the Internet can be improved.

The second is low latency. The so-called low latency is commonly referred to as time delay. This is a very big highlight of 5G.

The latency of 4G is 100 milliseconds, and the latency of 5G is only 1 millisecond.

It's not easy to understand. Then let's talk about a life example, and it will be easy to understand. For example, let's talk about the unmanned driving of cars. In the 4G era, there is no way to achieve unmanned driving. This is because the latency of a few hundred milliseconds in the 4G era cannot meet the control requirements of unmanned driving.

For example, when we are driving on the road, if we use the driverless state, we find that we are about to collide with the car in front of us, and we shout at the car to stop. There is a delay of hundreds of milliseconds between the time the car receives the stop command and the time it stops. Therefore, the wheels of the car will be in this delay of hundreds of milliseconds, and the wheels will turn a few more times, which will cause a rear-end accident.

And if it is 5G, then unmanned driving can be easily realized. It was also said that when we were driving on the road, we noticed a car in front of us, in order to avoid a rear-end collision. We shouted at the car to stop, because the delay time of 5G is only 1 millisecond, which means that as soon as we shout the voice, the car parking and our voice command can be fully synchronized. The wheels of the car also do not turn more than half a turn.

The advantage of low latency is a core indicator for 5G to completely crush 4G. This indicator will be used in many areas. Especially in many fields such as military, industrial control, and civilian automobiles.

Zhaohui then asked Zhu Weihua:

"That is to say, if the low latency of 5G is used on the super J CJ20, as long as we use the flying digital helmet to aim at the target, as long as we say fire, we can launch without delay. This will save at least half a second of time when those launch buttons are pressed. Isn't that true realization, that is, discovery and strike? ”

Your answer is absolutely correct. One millisecond is also one thousandth of a second, which is so short that there is no way to detect the time difference, which is almost equal to zero latency. Zhu Weihua added.

The third advantage of 5G is low energy consumption. It is also called low power consumption. In the past, when using 4G chips, the power consumption was relatively large when standby or in use. If you switch to 5G, then the energy consumption will be reduced by hundreds of times.

Let's take an example of practical application. For example, in order to prevent the lack of manhole covers on the road, causing people to accidentally fall into those wells when driving. We added a communication module to each manhole cover on the pavement. When the manhole cover is stolen or damaged, we can find it in time and carry out the remediation treatment of the manhole cover inside.

If the back of the manhole cover is equipped with a 4G communication module, then we need to change the battery for the communication module on the manhole cover in three or four days.

If the back of the manhole cover is equipped with a 5G communication module, then the battery only needs to be replaced once every six months or a year.

The main difference here is that the energy consumption of 5G is only a few hundredths of that of 4G.

5G is also widely used in low energy consumption. For example, in the future, various tests on the environment, whether it is the detection of earthquake disasters, the detection of river hydrology, the detection of atmospheric temperature, or the detection of border security. These places are not often frequented, you just need to put your 5G equipment there. When we change the battery for him, we only need to replace it once every six months or a year.

The fourth advantage of 5G is ubiquity. The popular point of ubiquity is that it can solidify the links of a large number of devices to form a network of all things interconnected. Conversational interactions can take place between any device and device, between a device and a person, and between a person and a device. A person can command the equipment, and the equipment can also directly command the equipment.

If there are dozens of devices connected to the 4G era, such as the devices that use 4G in the home, it is just a mobile phone, computer, router, etc. Then in the 5G era, it will access hundreds of thousands of devices in a timely manner. Anything that needs to be controlled in the home can be connected to the 5G network. There may be hundreds of devices connected to 5G in a single home.

If 4G has changed our way of life, it can realize food ordering, taxi hailing, online shopping, social networking...

Then 5G can revolutionize society. Homes become smart homes, factories become smart factories, cities become smart cities, and everything will become smart and technological.

After listening to Zhu Weihua's introduction, Zhaohui couldn't help but stand up and applaud him warmly.

"In the 5G era, there will be a lot of sensors, which is equivalent to any device having a human-like skin. The device senses the outside information through the sensor chip and makes corresponding judgments. My current task is not only to develop 5G mobile phones, but also to study the sensors needed for any device, as well as the intelligent systems that command the use of these devices. Make your devices AI-ready. Joe said.

"Gang Master Qiao, you are white-skinned and red-hearted, you are dripping big!" Zhaohui gave a thumbs up as he said to the Qiao gang leader.

"My idea is to start deploying 5G in some areas as soon as possible, and we can start with one or a few demonstration cities. Let it be promoted on a large scale later. Zhaohui said.

"We came up with one thought." Zhu Weihua said.

"We should also take into account the difficulties in advance, after all, 5G is here to change society and upgrade various industries." Zhaohui reminded.

"Actually, there are a lot of difficulties here. First of all, the capital investment is relatively large. Because 5G will require more than ten times as many base stations as 4G. There are about 3.5 million 4G base stations in our country, so 35 million will be needed for 5G. According to the calculation of an average of 1 million per base station, roughly 35 trillion funds are needed. If some outdoor base stations are excluded, in densely populated cities, and some transportation routes, etc., the base stations needed are estimated to be 10 million, and the capital demand is also 10 trillion. Zhu Weihua looked at Zhaohui.

"You go on." Zhaohui is actually prepared in his heart.

"The second is multi-industry synergy. This requires a series of work such as chip manufacturing, application system development, communication equipment manufacturing, and the addition of communication modules for various industrial equipment. This is not something that Hua Wei can handle, and it requires command and dispatch at the national strategic level. Zhu Weihua added.

"You don't have to worry about the funds, I'll figure it out. Things at the national strategic level, we need to write a detailed report. It is recommended that the country invest in the construction of 5G as soon as possible. Our country has an advantage, which is an advantage that no country can match. Zhaohui said.

"What advantages?" Zhu Weihua asked with Gang Leader Qiao.

"Mobilize the power of the whole country to do great things!" Zhaohui said proudly.
