N City, a café in the heart of the city.

After Su Qiyue pushed the door in, he saw the woman in red sitting in the corner at a glance.

Noticing where she was, the corners of Su Qiyue's mouth were slightly raised.

According to psychological analysis, most of the people who like to sit in the corner are affected by the "boundary effect".

The so-called "boundary effect" expresses the three psychological needs of human communication:

First of all, people have a psychological need to socialize, and boundaries are a good point of observation.

It gives a global view, followed by focused individual observations.

Before coming into contact with strangers, people will instinctively observe and grasp the information of the environment, and make appropriate judgments and choices - which people can become the object of interaction and cooperation.

Secondly, people need to communicate at the same time, but also need personal space.

In contrast to the environment in which the middle is surrounded by space, the boundary is a semi-open space in which people can observe and hide themselves at the same time – keeping their own spatial realm and reducing exposure.

Finally, people have the need to maintain interpersonal distance from others when communicating.

Standing at the border, on the other hand, is easier to get out of the area than standing in the center.

In the same way, if the other person is too close to you and you feel uneasy in communication, it is convenient for the person to re-distance themselves from the other person at the border.

Thinking of the screen name of this woman's "Little Red Riding Hood" and some of the traits she showed in the previous chat, Su Qiyue already had a basic judgment about her.

A rather conceited, perhaps even somewhat narcissistic woman.

Of course, through this one detail, there are many possibilities, and you can't just look at what a person is like from one behavior.

This choice of corner position may also be due to lack of self-confidence, which leads to the fear of being close to others.

Or maybe it's insecure, so look for something to lean on.

After thinking about it casually, Su Qiyue quickly walked to the table of the woman in red.

"Hello!"

Su Qiyue didn't ask if the other party was "Little Red Riding Hood", but simply asked hello.

"Ah, you're here, please take a seat!"

This "Little Red Riding Hood" was obviously thinking about something, and when he saw Su Qiyue coming over, he hurriedly got up and invited him to sit down.

"Su July!"

"Yang Qian'er!"

Both of them spoke at the same time, and at the same time extended their hands to each other.

Seeing each other's almost synchronous movements, Su Qiyue just smiled.

Reaching out and shaking the other party's white and soft soft squirt, Su Qiyue quickly let go.

"What do you drink?"

Yang Qian'er asked, leaning her neck.

"Cappuccino, thank you!"

Su Qiyue said calmly.

Yang Qian'er answered and beckoned the waiter over.

After helping Su Qiyue order coffee, Yang Qian'er then set her eyes on Su Qiyue's cheeks.

"You're younger than you are in the video."

Yang Qian'er pursed her lips and smiled, "If it weren't for Sister Manqing telling you about you, it's hard to imagine that you would have graduated with a doctorate at your age." ”

"When I graduated at the age of twenty-six, I was already the youngest in the department......

Su Qiyue knew that Yang Qian'er herself also graduated with a doctorate.

Moreover, it is one of the top universities in the country.

Listening to her emotion, Su Qiyue smiled and didn't say anything.

Thinking that he had truly judged the age of the other party without knowing it before, Su Qiyue was a little funny.

The two chatted for a while, and Yang Qian'er got to the point.

"I saw you today, mainly to talk to you about co-founding a company......

Seeing that this female doctor's style was so straightforward, Su Qiyue was a little appreciative.

In these years, as people become more and more indifferent to each other, there are fewer and fewer people who dare to express their opinions with strangers.

"Well, I've already heard the basic situation from my senior sister."

Su Qiyue nodded and said, "Miss Yang has the idea of starting her own business, of course it's good." Senior sister, there is no problem. ”

"However, I can't intervene in your cooperation. Please also ask Miss Yang to understand. ”

Hearing this, Yang Qian'er suddenly showed a look of disappointment.

Speaking of which, the reason why she gave up her high-paying job and chose to start her own business.

In addition to being unwilling to be unwilling to know the future at a glance, being able to accidentally meet Su Qiyue and Yan Manqing is also an important factor.

The technical level of these two young people in terms of information security and network security amazed Yang Qian'er.

Especially Sue July.

When he solves some network security problems, his thinking is completely different from ordinary people, and he has a kind of advanced thinking.

After meeting with Yan Manqing and having an in-depth understanding, Yang Qian'er's desire to cooperate with these two people became even more urgent.

At this time, after listening to Su Qiyue's refusal, Yang Qian'er was naturally a little frustrated.

Noticing her expression, Su Qiyue smiled and said, "Although there is no way to join your company, I can still give some advice and help in terms of technology." ”

"After all, the development of computer technology in our country is also a great good thing for the country."

When Yang Qian'er heard this, her eyes suddenly lit up.

"With Mr. Su's words, then my company will definitely do it"

Su Qiyue sighed and said: "There are many development directions of network companies, has Miss Yang considered which category to start with first?" ”

Listening to his question, Yang Qian'er quickly replied: "First of all, the first direction, of course, is the research and development of network security systems. This is also a matter related to our three majors, and it is almost not difficult to carry out. ”

"On top of that, now that the 3G era has begun, the outlook for communication technology and IT skills is also promising."

Yang Qian'er tilted her head sideways, looked at Su Qiyue with burning eyes, and said, "So I also want to try in this regard." ”

Listening to the female doctor's eloquent conversation, Su Qiyue nodded slightly.

Indeed, the other party still has a deep insight into the characteristics of the network in this era.

In addition to cybersecurity, communication technology and IT skills, future applications will definitely usher in an explosive growth.

Although Intel, Qualcomm and other IT companies have formed an industry monopoly to a certain extent, the layout has been a little slow.

But it's better to be in the game than not to be in the game.

Moreover, Su Qiyue believes that with his understanding of the information in the industry in his previous life.

At least in terms of epoch-making techniques, it can still provide some help to this "Little Red Riding Hood", so that they can avoid some detours.

Thinking of this, Su Qiyue sighed and said: "Miss Yang is right, communication technology is indeed the focus of multi-party competition in the future technology market. ”

"However, there are several ways for communication technology to go now. For example, GSM, CDMA, GPRS, your main direction of attack, where are you going to put it? ”

Hearing this, Yang Qian'er suddenly blurted out: "Of course it's CDMA." ”

"First of all, the call quality of CDMA is higher than that of GSM, and the noise of CDMA is much smaller than that of GSM when calling in the same environment; Secondly, CDMA uses excellent power control technology, so the radiation of CDMA mobile phones is much smaller than that of GSM. ”

"So I judge that in the future of wireless communication, CDMA will definitely be in a dominant position!"

Listening to Yang Qian'er's story, Su Qiyue sighed, revealing a noncommittal expression.

The so-called CDMA actually means multiple access to code division.

It refers to multiple access communication that uses code sequence correlation.

The basic idea is to distinguish addresses by different address codes.

Each is equipped with a different address code, and the carrier transmitted by the user is modulated by both the baseband digital signal and the address code.

When receiving, only the receiver that knows the address code assigned to it can demodulate the corresponding baseband signal, while other receivers cannot demodulate the signal because the address code is different.

Due to the superimposition of pseudo-random codes when transmitting signals, the spectrum of the signal is greatly widened.

Therefore, the communication system using CDMA technology is also known as the spread spectrum communication system.

It is a bit a lot, such as high spectrum utilization, good voice quality, strong confidentiality, low call drop rate, small electromagnetic radiation, large capacity, wide coverage, and so on.

From the perspective of 3G development, CDMA is indeed in a leading position.

However, Su Qiyue knows the rise and fall of various network systems in the future.

The future development of CDMA will also encounter some bottlenecks.

In this case, Su Qiyue prefers another network standard.

Noticing the disapproving look on Su Qiyue's face, Yang Qian'er frowned slightly.

She pondered for a moment, and then she said, "Mr. Su, although we are only meeting for the first time, we are already old friends in terms of technical discussions, right?" ”

Seeing Su Qiyue nodding, Yang Qian'er smiled and said, "So, if there is any problem, you just have to tell me directly, don't worry about my thoughts."

Su Qiyue touched his cheeks, nodded and said, "Why don't you try to develop in the direction of LTE network standards?" ”

"LTE network standard!?"

When Yang Qian'er heard this, she was a little stunned.

Su Qiyue nodded and said to himself: "Not long ago, the LTE system was officially established and launched at the DLD meeting. ”

"This system introduces key technologies such as OFDM and MIMO, which significantly increase spectral efficiency and data transfer rates."

Su Qiyue said conclusively: "With the rapid arrival of the global information age, the total amount of data will show explosive growth. The demand for data and information is also increasing. ”

"In this case, LTE systems came into being. It is very forward-looking in terms of optimizing wireless communication technology......"

Listening to Su Qiyue's remarks, Yang Qian'er's mouth opened slightly, with a stunned expression.

Originally, Yang Qianer's idea for the new company, network security and information security pointed to the efforts of Su Qiyue and Yan Manqing.

As for wireless communication, Yang Qianer is more familiar with it.

After all, her undergraduate is a related major.

Who knew that the young man in front of him also had good insights in wireless communication.

This made Yang Qian'er suddenly feel a little lost.

Su Qiyue didn't know what the female doctor was thinking, and continued to tell herself.

"Many people say that the reason why LTE systems should abandon CDMA technology is to avoid the monopoly of Qualcomm's CDMA patents."

"But in reality, CDMA technology still plays an important role in this new system."

After the other party digested for a while, Su Qiyue continued to say aloud: "The current CDMA technology in China is relatively mature, and the development of the LTE system is undoubtedly twice the result ......with half the effort."
