According to the rules of the International Radio Association, the existing radio communications are divided into more than 50 different services, such as aeronautical communications, marine communications, land communications, satellite communications, radio, television, radio navigation, positioning, telemetry, remote control, and space exploration, and a certain frequency band is specified for each service.

In view of this situation, China Unicom came forward to report to the Ministry of Posts and Telecommunications and applied for a wireless frequency band. ALL COUNTRIES HAVE STRICT REGULATIONS ON RADIO COMMUNICATION TRANSMISSION, AMONG WHICH CHINA'S INTERIM RADIO MANAGEMENT MEASURES STIPULATE THAT THE FREQUENCY BAND OF CIVIL WIRELESS COMMUNICATION IS 800MHZ TO 3000MHZ, AND THIS BANDWIDTH SHOULD BE DIVIDED BY MULTIPLE COMPANIES. Although these companies have not yet been born, but China is so big, it must not be monopolized by one company, and the leaders are considering splitting these frequency bands by four or five companies, and China Unicom will first divide one-fifth of the frequency bands for them to use.

With the wireless frequency band, the wireless communication transmission standard can be formulated, and the development of wireless transmission base station can be officially started.

The establishment of the base station is very knowledgeable, and if the design is not good, there will be blind spots, that is, there will be no signal on the mobile phone. China Unicom uses three methods of full coverage of wireless transmitter signals, the first is to pave along the highway, like large power poles, at every intersection, every how far away. The highway is one of the areas where mobile phones are used the most, so it is necessary to focus on setting up transmitting base stations.

The second is to set up a large base station on a relatively high mountain, which is a supplement and extension of the highway base station. Vast rural areas such as the vast ones are this second type of base station.

The third is a small transmitter, or a signal radiator, which is available in every building, and is generally arranged in urban areas, crowded places, such as: stations, shopping malls, airports, etc., as well as tunnels, subways, underground parking lots, and the signal blind spots of these large base stations.

In fact, there is another one, that is, the user's home wireless router, which can also be responsible for wireless communication transmission. Of course, our current wireless router can't do it because it's not a company or a standard, and it can't support it. But the wireless router developed by the Electronics Research Institute can, which is also a benefit of a company.

Through the above methods, the signal can basically be achieved without dead ends. The wireless transmission station is jointly developed by the Institute of Electronics and China Unicom, and is fully managed by China Unicom.

The mobile phone is easier, because the early pioneer MP4 has been more perfect, that is, the wireless communication module and wireless Internet technology are missing. As long as China Unicom's wireless communication base station is well arranged, it can be put into use.

During this time, the largest increase in personnel is undoubtedly the Institute of Mechanical Technology, and it is very easy for Changsheng Investment Group to recruit people today. The Institute of Mechanical Technology can recruit mechanical engineers nationwide, so its staff has expanded rapidly, from a few hundred engineers to more than 5,000 mechanical engineers.

Because they have set up several subordinate companies, they need so many people. The first is Giant Spirit Heavy Industries, a company that mainly develops heavy vehicles, buses, trucks, trailers, and heavy construction machinery. This enterprise alone is divided into more than 2,000 mechanical engineers. In addition to the large buses and trailers that have been developed, they are now developing large trucks, dump trucks, excavators, loaders, forklifts, concrete pump trucks, cranes, etc., and some of them are busy with work.

The second is the Heavy Machinery Company, which is a company that mainly develops extra-large equipment. For example, 100,000 tons of hydraulic presses, hydraulic presses, oil die forging presses, large-scale rolling equipment, large-scale mining equipment, tunnel machines, etc., in short, they are the development of coarse guys. This company also has more than a thousand employees, and the tasks are relatively heavy, and there is not a single idle person.

The third is a heavy machine tool factory, specializing in the production of large-scale high-end precision CNC machine tools, which is a mainly external company, and the current customers are mainly military systems. This company was established relatively early, and basically all types of machine tools have been developed, so there are only dozens of mechanical engineers responsible for technical guidance, and the rest are ordinary workers.

The rest of the people are responsible for the mechanical design tasks and production line design tasks of other subsidiaries of the company, and the personnel are still relatively tight.

Other scientific research institutes were originally expected to be moved next year, but because of the addition of special trains, the relocation speed of the Guangzhou Railway Group has been much faster, and all the relocation has been completed by now. So far, Huizhou has become a pure production base and export base, and the safety has been greatly guaranteed.

Other scientific research institutes also have a relatively large growth, but because they are not social-oriented enterprises, they are basically enterprises that provide basic materials, materials and important parts, so they are not well known to the people of the country, so they will not be specially introduced. However, their role cannot be ignored, and the products designed and produced by the other three units and enterprises would not have been able to lead the world without them providing materials and important components.

Science and technology research and development enterprises like Changsheng Investment Group, the impact on China is huge, that is, various types of CNC machine tools, there is a huge increase in the development of China's productive forces, and China's mechanical products are no longer shoddy, but comparable to European and American products, which can not be described in words.

There are also gas turbine generator sets, which also make some large cities no longer lack electricity. There are also Changsheng Construction Engineering's city square projects in major cities, which also made the local government realize the importance of commercial real estate in advance, so pedestrian streets have sprung up all over the country.

If China's products catch up with foreign countries in terms of precision, then there is no market for foreign products in China. This has been proven by later generations, after all, the cost of manufacturing products abroad is much higher than that of China.

In addition, Changsheng Investment Group provides a large number of unconditional chip supplies to China, so that domestic enterprises have also begun to transform to CNC products. This is a period of great change, and foreign countries have not gone too far, so the subsequent development is unpredictable.

These are just variables, everything depends on time to ferment, the world has not yet noticed, but the energy generated by the burst in the future is unstoppable.

This is not to be mentioned, it is precisely because of the healthy and orderly development of Changsheng Investment Group that Shen Danqing still stays at Tsinghua University to study with peace of mind, and there is a taste of not listening to things outside the window and only reading sage books.

One afternoon after school, Shen Danqing was playing basketball with his classmates, after such a long time of exercise, his ball skills have also improved a lot, and he dared to shoot the blue cricket ball himself. The posture is becoming more and more natural, and it is no longer the appearance of a big stupid bear.

Everyone knows that basketball uniforms are sleeveless and loose sportswear, so when Shen Danqing played basketball, he showed his muscular arms, and he didn't know when he attracted a group of fan girls, who came to cheer him on whenever he played. In this way, the graduate student team finally has a cheerleading team, although it is only him, but it still looks much better. In this way, the interest of the cattle to play is also much higher.

"Good ball, No. 8 is great!" When Shen Danqing wore the No. 8 jersey and grabbed the rebound and scored another ball, the girls on the side cheered.

Shen Danqing has an advantage in playing ball, that is, he is heavy, and when he is playing with the ball, ordinary people can't stop him, and he can easily knock him away. This is tantamount to cheating, because the other classmates are basically hemp rods, or fat people, and none of them weigh more than him anyway. Because of this, now it is basically their class winning, and the two teams are gradually a little out of balance.

When the game was over and the score was 37-108, the captain Huang Zili said to the captain of the graduate class next door: "Alas, it's boring, next time I can see if I can play a game with the school team, and I won't be interesting to win against you fish belly teams." ”

"You're embarrassed to say, if you don't have a soldier in your class, you and we will be half a catty, and the next game, the soldier won't play, see if you can win." The captain retorted unconvinced. He has his reasons, mainly because Shen Danqing almost took the rebound, he stood there, like an iron tower, how could others rob him. The graduate team doesn't have a high shooting percentage, and losing a rebound is equivalent to giving someone a point, which is the reason for the big score.

Of course, Huang Zili just said that if he really wants to compete with the school team, he will also lose miserably, because only he and Shen Danqing can play the role of the whole team.

On the other side, when Shen Danqing left the field, a large group of beauties surrounded him at once, and only beauties had the confidence to come to him. After all, Shen Danqing's figure and appearance are too outstanding, and compared with him, the stars on TV are weak.

"Senior Shen Jun, give, drink saliva first. A tall beauty handed him a bottle of mineral water. But Shen Danqing didn't answer, he smiled and said to the beauties around him: "Ladies and gentlemen, I appreciate your kindness, but I am ashamed of my kindness to you, because I already have a wife and children, I don't believe you to ask my classmates, they have all seen my wife and children." ”

"You lied to us, you are still studying, and you are so young, how can you have a wife and children?" retorted a female classmate in disbelief.

"I am a self-funded graduate student commissioned by the unit, I have already joined the work, of course I have a wife and children! Many students know this, you go to inquire to know if I am panicked, besides, you are so beautiful, if I am not married, I will also pursue one of you. Shen Danqing said to them with a sincere smile.

"Which of us will you pursue?" asked a female classmate.

"Hmm...... This one...... Because I'm not qualified to pursue you, I haven't looked closely, so I can't say who I like. Shen Danqing was a little overwhelmed, and thought of a barely justifiable reason to prevaricate.
