What is Comrade Gao Cheng doing, who is being choreographed by them, of course, he has something to do by himself, and he has nothing to do.

Gao Cheng is on the phone with his teacher, about his doctoral study, he has passed his teacher's assessment, as for the project assigned to him by the teacher, it has also been successfully completed.

This time I called his teacher, and it was really not about his doctoral topic. This time, I contacted their teacher mainly to consult about the monitoring of the electromagnetic spectrum.

Isn't this just the task that the troops have just received on the security of the Olympic Games, and Gao Cheng hopes to find a breakthrough here in terms of the information-based monitoring means he understands and the spectrum monitoring, so that they can make a better use during their mission.

"I also consulted the experts of our school for you about the questions you mentioned, and the specific ones have been sent to your mailbox. I said that you kid didn't do the subject I gave you, so why did you study this subject again. Is it because you have too much time and feel like you have no place to use it? Mr. Takajo asked on the phone.

"Teacher, not really. Isn't this the fact that the troops have received a task, and it is inconvenient to say more about the specifics. I think we also have an electronic team in our army, but it may not play a big role in this mission, and if we can use the electromagnetic spectrum to monitor and have them grade according to frequency, I think there is a lot to be done in this regard. Takashiro explained.

"Okay, you always have a reason. I won't rush your project too much, but I can't delay my research because of tasks or other things. I still hope that you can achieve something in your studies, you are my most optimistic student. Academician Wang sighed.

Gao Cheng also sighed a little, he has always understood the expectations of the teacher, otherwise he would not have entered the teacher's door to study for his doctorate. Here in Yanjing, it is not that there is no big bull in computer science, and he can go directly to interview for a doctorate from a big cow.

But Gao Cheng has already disappointed his teacher once in the choice of life path, and if he does that, it is estimated that it will be similar to the betrayal of the ancient school.

As for why Gao Cheng raised a new question this time, electromagnetic spectrum monitoring, the main reason is for the task of Olympic security.

Not to mention how much effort the country has spent on this event this time, it is for the future development of the army, and this technology is also a hurdle that Gao Cheng must overcome.

Why do we say that, we must first understand what the electromagnetic spectrum is. The electromagnetic spectrum is scientifically defined as a family of electromagnetic waves that are arranged continuously according to the wavelength or frequency of electromagnetic waves.

Just looking at the definition, it doesn't really matter much. But as far as modern military development is concerned, its importance is no less important than the development from the age of cold weapons to the age of firearms.

In military affairs, it is not only a carrier for transmitting information, but also an important means of obtaining intelligence. In the information war, he has become an important weight that affects the victory of the war.

Speaking of the electromagnetic spectrum, I have to put forward another concept, cyberspace. This concept was proposed by the lighthouse country in the 90s of the 20th century, and Cyberspace is basically synonymous with the Internet (Internet).

Cyberspace does not include the concept of the electromagnetic spectrum, but is defined as a network of thousands of interconnected computers, servers, routers, converters, and optical fibers that enable critical infrastructure to work.

However, with the advancement of science and technology, the definition of electromagnetic spectrum has been further expanded into cyberspace, and then the definition of cyberspace is mainly composed of three parts: electromagnetic spectrum, electronic systems and networked infrastructure.

The electromagnetic spectrum is not only a medium for transmitting data, but also an important tool for obtaining information. According to statistics, nearly 50% of users use wireless methods (including Wifi, 802.11, WiMAX, etc.) to access the Internet; Mobile communication accounts for more than 70% of the communication network; In industrial control systems, the proportion of wireless transmission is also increasing; In the fields of geological exploration, intelligent transportation and space exploration, radio systems with electromagnetic probes and radars as sensors play an irreplaceable role.

Spectrum is a finite, non-renewable strategic resource. The electromagnetic spectrum is a public resource, and since it has the attributes of a resource, it must be accommodating. It is not infinitely renewable, so spectrum management is a problem that countries need to face today.

Of course, Gao Cheng is not here to discuss the issue of spectrum management, he is mainly consulted about spectrum monitoring. This form of monitoring can be found to be different from the existing frequency-using terminals, and has a high detection ability for investigating foreign or domestic criminals.

Putting down the phone, Gao Cheng exhaled lightly. Every time he communicates with the teacher, he feels guilty. Of course, it is also because he is "taking" every time, and he feels a little uncomfortable.

Looking at the email sent by the teacher, about the monitoring of the electromagnetic spectrum, the feasibility of the information was put forward in detail. The technical requirements for this have already been implemented.

It is mainly for the technical implementation of spectrum management, and if you want to monitor the spectrum, as long as the mission force conducts spectrum monitoring of the target area, there are not too many technical requirements or modification needs.

Gao Cheng was happy in his heart, there were no technical requirements, and their electronic team basically could get started as long as they were equipped, and they didn't need to do the corresponding training.

"Heh, it was still a little too narrow before, and the form of electronic warfare was still not fully understood. It seems that in the future, we must learn more about other aspects of electronic knowledge, otherwise it may overturn that day. Gao Cheng said self-reflectively.

It's not that he underestimated himself, but he just felt that he might be ahead of his time and be one step ahead of others in the development of the army's informatization. But in the end, he is a human being, and he is a human being who has not been reborn with a system.

If you want to think about everything clearly, or be able to arrange the details of development many years later, it is not real life, that is, fantasy.

While Gao Cheng was struggling on his side, training was in full swing in a military base in Daxing District, Yanjing.

"Chief, this is the elite unit left over from the past two years. They are all selected from various branches, proficient in multiple skills, and can fully ensure the smooth reporting of this event. The head of the base, a colonel, said.

It is not a soldier who is at the front, but as a government functionary, plus his deputy to the Olympic organizing team, he is qualified to be called a chief.

"Lao Liu, there are more than 800 armed police officers in Yanjing, plus more than 300 of you here, I believe you can ensure the safety of the urban area." Said the chief who came to inspect.

Hearing the chief's reply, the colonel was not so pleased. What the chief means is that they will also be able to ensure security within the city limits, and outside the city area, that is uncertain.

"Chief, we are confident..."

Before the colonel could finish speaking, the chief waved his hand and motioned for him to listen to him.

"Lao Liu, I know what you mean. You've been making selections since two years ago, and you've been selecting people layer by layer. We can all see and understand the hardships. I didn't mean to deny what you meant, and we can rest assured that the security task will be entrusted to you. But peripheral tasks also need us to deal with. The chief said.

This colonel understands this, after all, their army is only 300 people, and it sounds like a battalion-level unit, but if it is placed in the entire Yanjing, it is impossible to guarantee a soldier even one street, let alone the peripheral areas.

"One of the reasons for coming here this time is to see how we're training. I would also like to inform you that there will be a meeting of the preparatory team for security in the near future. Your troops, plus the armed police force, and the military responsible for perimeter security will all participate, and you can talk to each other when the time comes. ”

Senior Colonel Liu smiled bitterly and said, "No problem, chief, there can't be a problem in this sports event no matter what." As long as we can ensure the smooth convening of this grand event, we will not take it lightly. ”

"That's good, the specific time and other notices, it is estimated that it will be soon. After all, there are many places that need to be familiar with each other, and I hope that you can work together to complete the tasks assigned to you by the state. The chief said.

"Yes, chief, make sure to complete the task." Senior Colonel Liu saluted.

Seeing the chief's convoy leave, Colonel Liu turned around and returned to the base. The correspondent beside him whispered: "This is almost the beginning, and suddenly the troops are added, can this be cooperated?" ”

"Alright, don't talk nonsense. We are the main force in this mission, didn't you hear what the chief said, we are responsible for the security task of the urban area, and the other party is responsible for the security of the peripheral areas. In any case, I don't want anything else to happen in this mission, and this is also a reward for the hard work of our troops. Colonel Liu said.

"Yes, Chief!" The correspondent didn't dare to say anything else, and followed Colonel Liu back to the base.
