After returning to the imperial capital after the tour, Zhaohui took Haiqing Haiya to the imperial capital University of Posts and Telecommunications. I made a special trip to visit Professor Kan Kaikai. Professor Kan is a leading figure in the field of communications in China.

Professor Kan warmly received Zhaohui and explained the development status of today's communication and the communication pattern that will appear in the future.

According to Professor Kan's description, our world today is in the era of the second generation of communications, also known as the 2G era for short. The first generation of communication, that is, 1G, is the era of analog signal communication. The second generation is the era of digital communications.

The so-called analog communication is actually the transmission of signal information in an analog way. By analogy, digital communication transmits digital information.

The radios we used to use, and the TV we watch now, are still analog signals. Analog information has many disadvantages compared to digital information. For example, the amount of information carried by the signal is small, so analog TV is not as clear as digital TV. The confidentiality of analog signals is also relatively poor, and it is easy to be cracked or even easily interfered with. The power consumption of analog signal devices is also very large, so the big brother of the first generation of mobile phones is very large.

The birthplace of the second generation of digital information and communication is Europe. The United Nations has one of the longest-standing organizations called the International Telecommunication Union (ITU), or ITU. They are responsible for developing or reviewing standards for world communications. Today's second-generation digital communications, which can be abbreviated as GSM, are also known as global mobile communication technology. This standard was set by Europeans. ITU has embraced the European GSM standard as the second generation of communications standards around the world.

When a standard is set by whom, then it will bring great benefits to whom. Because they have a large number of patented technologies under this standard. In this way, technical barriers are formed, and whoever uses it must pay them a huge amount of patent fees.

Therefore, almost all mobile phones in the world are the brands of European companies. Nokia, Philip, Elyson, Ercarter... Sam's Motorcycle, Docomo, and Koryo all have to pay patent fees to these patented communication companies in Europe.

Our country's Xia Xin, doctoral supervisor, and TGL also have to pay patent fees.

After introducing this, Professor Kan stood up, lit a cigarette, walked to the window, and looked into the distance in deep thought.

"Then, if our country develops the third generation of communications, that is, 3G, will we lead the development of communications in the future, and the whole world will have to pay patent fees to us?" Zhaohui asked.

"Yes, you're right." Professor Kan took two puffs of his cigarette, then extinguished it and sat back on the sofa. Then he continued to introduce Zhaohui.

Let's do the math of an economic account. The world's 6 billion people, based on young and middle-aged people, assuming only 60% of the population, would have 3.6 billion mobile phones. If each mobile phone is averaged at 2,000 Chinese dollars, then the market for mobile phone terminals alone is as high as 7.2 trillion Chinese dollars.

To achieve communication in mobile phones, a large number of communication base stations are also needed, as well as cables used to connect base stations, optical fibers, equipment used in communication rooms, all the software of the billing system, users use communication, and pay telephone bills, etc., which is a huge industrial chain. The entire industrial chain is estimated to reach a market size of at least several trillion yuan.

Therefore, whoever masters the standards of a communication era can master the market of tens of trillions. In the future, not everyone may have a computer, but everyone will definitely have a mobile phone.

"Professor Kan, from the perspective of a consumer, can I imagine what I want my mobile phone to look like?" Zhaohui was a little impatient.

"Well, now some economically developed countries in the world have begun to invest heavily in the research and development of the third generation of digital communications. There is not yet a mature technical standard, and the standard for application use. You can imagine it wildly. Professor Kan encouraged Zhaohui.

"I want a mobile phone that can not only make phone calls, this is the most basic function, and it can be said that 2G GSM has been realized. I hope that in the future, 3G, or even 4G or 5G, will become super powerful. For example, she is a small TV, and she can see the video wherever she goes. She is not just a mobile phone that can only receive videos and cannot participate in video interactions. She also has a computer, and I can use my phone to interact at any time. People can use mobile phones, not only voice contact, but also pictures, videos, text and other forms of interaction..."Zhaohui is imagining to himself

"Zhaohui, what you said is so good, no wonder you are the super brain of our Dragon Kingdom." Professor Kan was also excited.

"If we're going to make these apps happen, what do we all need to work on?"

Professor Kan became contemplative, he was desperately digging into what he had learned and accumulating, and he was even making predictions about the future.

For ten minutes, Professor Kan was in the room, pacing.

Zhaohui didn't dare to interrupt Professor Kan's train of thought, he could only wait for Professor Kan.

Finally, Professor Kan paused, then crossed his fingers and shared his thoughts with Zhaohui one by one.

First of all, we need to develop 3G and even 4G and 5G communication technologies. It must be a broadband-based form of communication. Broadband communication methods can carry a larger amount of information for transmission. At present, 2G is still a narrowband communication technology. The bandwidth required for voice communication such as making a phone call is very small.

Communication technologies that need to support text, images, and even video must require a lot of bandwidth. It's like the wider the road, the more cars you can run.

Secondly, this broadband communication technology needs the support of corresponding broadband electronic components. The core is that the chips in the base station equipment of communication and the chips in mobile phones must support this broadband communication technology.

I know that our country has made a lot of breakthroughs in the field of chips. We are already able to produce CPUs for computers. The chip required by the mobile phone is smaller than the chip used by the computer, and the computing power is also very high, otherwise, there will be insufficient computing power, resulting in the lag of the video screen.

Optical chips are estimated to have three categories. One is a computing chip for information processing, like a CPU in a computer. The other is the memory chip, 3G, 4G these broadband digital communications, need to have a hard disk like a computer to store information, so the mobile phone must also need a memory chip.

The last one is the baseband chip. The so-called baseband chip is also called the coding chip. For example, when we use a mobile phone to make a call, the mobile phone converts people's voice signals into electromagnetic waves, and then the electromagnetic waves are encoded, and the mobile phone emits the programmed digital. The process of answering the phone, on the contrary, is to parse and restore the received code into sound. The baseband chip is the chip responsible for the coding and processing of digital information before sending and receiving.

As long as the problem of these three chips can be solved, nothing else is a thing. As for those mobile phone screens, motherboards, batteries, etc., they are all minor problems compared to mobile phone chips.

The third is the software operating system. It's like a computer, you need a computer operating system. A computer cannot be used without hardware and an operating system. Broadband mobile phones such as 3G and 4G also need their own operating system. Only when we use the mobile phone operating system, can we command the mobile phone and let the mobile phone help us realize applications such as making calls, sending pictures, and watching videos.

If we can lead in 3G, 4G and even 5G, we can lead in the future development of the world. We form our own patent standards, submit them to ITU for consideration and release, and then the standards for world communication will be formulated by Longguo in the future.

Major brands around the world want to produce 3G and 4G mobile phones. If you want to buy chips from us, you have to pay us patent fees.

The equipment used in the world's communication base stations is provided by our Dragon Country. The mobile phones used by people all over the world, the core chips, and the mobile phone operating system are all provided by our Dragon Kingdom.

By the way, there is another very important link that I almost forgot. That's the application software. We know that with computers comes the development of various computer software.

If we release a mobile phone operating system, any mobile phone application software developed for mobile phones in the world in the future must be carried on our mobile phone system. Therefore, in the future, no matter how many mobile app development companies there are, they will have to play according to the rules of the game we have set and pay us a fee.

The revenue brought by the application software market may be dozens or hundreds of times greater than that of selling mobile phones and base station communication equipment......

The more Professor Kan spoke, the more excited he became, his face flushed, as if he had seen great results in the next ten or twenty years.

Zhaohui's super brain quickly receives and processes Professor Kan's information. A more magnificent picture took shape in Zhaohui's mind.

The future of communication will be more than just a conversation between people. A person can command mechanical equipment, a person can command a car, and a person can command any electrical appliance in the home.

Machines can also command each other. The machine seems to have a nerve skin, which senses external information through sensors, and then transmits the sensing information to the CPU brain, and then the brain sends instructions to direct the machine to make corresponding operations.

From machine to machine, isn't it, The I

et of Thi

gs (IOT), everything can be connected together to form a network of all things connected.

Humanity will enter an era of intelligence! Machines will also enter an era of artificial intelligence, ARTIFIC

IAL INTELLIGENCE (AI), MACHINES CAN MAKE LOGICAL JUDGMENTS AND EXECUTE LOGIC, AND MACHINES CAN CONTINUE TO LEARN AND BECOME MORE POWERFUL TO HELP HUMANS DO MORE......

Zhaohui and Professor Kan chatted for a whole day. Before you know it, it's night. Professor Kan invited Zhaohui to stay and have dinner together. However, Professor Kan is dedicated to learning, but he is not good at cooking.

The cooking work was naturally taken care of by the sisters Haiqing and Haiya. Professor Kan then noticed the beautiful sisters. Professor Kan pointed at Zhaohui and joked:

"Your kid is really beautiful, and his mouth is not shallow. But then again, if I had a daughter like you, I would have to hire you as a son-in-law. I don't have a daughter, but a few of my graduate students are very beautiful, do you want me to introduce you? Haha..."

After Haiqing heard it, he whispered something next to Haiya's ear.

"Sister, when you stir-fry later, put an extra handful of salt and kill them!"
