City n, a cafe in the city center.

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

Noting where she was, Su Qiyue's mouth raised slightly.

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

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

First of all, people have psychological needs for interaction, and boundaries are a good point of observation.

It can provide people with global browsing, followed by individual observations of the key points.

Before contacting strangers, people will instinctively grasp environmental information through observation and mastering, make appropriate judgments and choose who can become the objects of interaction and cooperation.

Secondly, while people need communication, they also need personal space.

Compared to the environment where space is surrounded by space, the boundary is a semi-open space, where people can observe it while hiding themselves and retaining their own space areas to reduce exposure.

Finally, when people communicate, they need to keep interpersonal distance from others.

And standing on the border is easier to leave the area than standing in the center.

Similarly, if the other person becomes uneasy during communication because the other person is too close to him, it can be convenient for people to regain distance from the other person at the boundary.

Recalling the online name of this woman "Little Red Riding Hood" and some of the traits she showed during her previous chat, Su Qiuyue already had a basic judgment on her.

A woman who is quite conceited and may even be somewhat narcissistic.

Of course, through this detail, there are many possibilities, and it is impossible to see how this person is like from just one behavior.

This person may also be because he is not confident, which leads to his inability to get close to others.

Or lack of security, so you need to find support.

After a casual imagination in his mind, Su Qiuyue quickly walked to the table of the woman in red.

"Hello!"

Su Qiuyue did not ask whether the other party was "Little Red Riding Hood", but simply asked a question.

"Ah, you're here, please sit down!"

The "Little Red Riding Hood" was obviously thinking about his thoughts. When he saw Su Qiuyue coming, he quickly got up and invited him to sit down.

"Su Qiyue!"

"Yang Qian'er!"

The two spoke at the same time and extended their hands to each other at the same time.

Seeing each other's actions almost synchronized, Su Qiyue smiled.

He reached out and grabbed the other party's white and soft soft horns, and Su Qiuyue quickly let go.

"What do you drink?"

Yang Qian'er asked with her neck tilted.

"Cappuccino, thank you!"

Su Qiuyue said calmly.

Yang Qian'er responded and waved to the waiter and called him.

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

"You're younger than in the video."

Yang Qian'er pursed her lips and said, "If it weren't for listening to Sister Man Qing's talk about you, it would be hard to imagine that you would have graduated from a doctorate at your age."

"When I graduated at the age of 26, I was already the youngest in the department..."

Su Qiuyue knew that Yang Qianer herself also graduated from a doctorate.

Moreover, it is one of the best universities in China.

After hearing her feelings, Su Qiuyue smiled and said nothing.

Su Qiuyue was a little funny when she thought that she had truly judged the other party's age without knowing it.

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

"I meet you today, mainly because I want to talk to you about cooperating with you to start a company..."

Seeing that the female doctor's style was so straightforward, Su Qiuyue admired it a little.

In this era, as people become more and more indifferent to each other, fewer and fewer people dare to express their opinions directly with strangers.

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

Su Qiyue nodded and said, "Ms. Yang has the idea of ​​starting a business on his own, so of course it's good. There is no problem with his senior sister."

"However, I cannot intervene in your cooperation. Please understand Ms. Yang."

After hearing this, Yang Qianer immediately 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 give up on his clear future, being able to accidentally get to know Su Qiuyue and Yan Manqing is also an important factor.

Yang Qianer was amazed by the technical level of these two young people in information security and network security.

Especially Su Qiyue.

When he solves some network security problems, his thinking is completely different from that of ordinary people and he has a forward-looking thinking.

After meeting Yan Manqing and getting to know her deeply, Yang Qian'er's mood to cooperate with these two people became even more urgent.

At this time, after hearing Su Qiyue's polite rejection, Yang Qian'er was naturally a little depressed.

Noting her expression, Su Qiuyue smiled and said, "Although I can't join your company, I can still give some advice and help in terms of technology."

"After all, our domestic computer technology has developed well, which is a great thing for the country."

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

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

Su Qiuyue said with a whisper: "There are many directions for the development of the Internet company. Have Ms. Yang considered which category to start first?"

After hearing his question, Yang Qianer quickly replied: "First of all, the first direction is the research and development of network security systems. This is also a matter related to our three majors, and it is almost no difficulty to carry out."

"In addition, the 3G era has begun, and the prospects for communication technology and IT skills are also optimistic."

Yang Qian'er turned her head and looked at Su Qiyue with a bright look, "So I want to try it in this regard."

Listening to the female doctor's talk, Su Qiuyue nodded slightly.

Indeed, the other party still has deep insights into the network characteristics of this era.

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

Although Intel, Qualcomm and other IT companies have now formed industry monopoly to a certain extent, their layout has become slightly slower.

But entering the game is better than not entering the game.

Moreover, Su Qiuyue believes that he has understood the industry information based on his previous life.

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

Thinking of this, Su Qiuyue said, "Ms. Yang is right. Communication technology is indeed the focus of competition among many parties in the future technology market."

"However, there are several ways to go for communication technology now. For example, where are your main attack directions?"

After hearing this, Yang Qianer blurted out: "Of course it's cdma."

"First of all, the call quality of cdma is higher than that of gsm. When making calls in the same environment, the noise of cdma is much smaller than that of gsm; secondly, cdma adopts 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, CDMA will definitely dominate the wireless communications sector!"

Listening to Yang Qian'er's story, Su Qiuyue quit and showed an undeniable expression.

The so-called cdma actually means code division multiple access.

It refers to multiple access communications achieved using 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.

During reception, only the receiver that knows its allocated address code can demodulate the corresponding baseband signal. However, other receivers cannot demodulate the signal due to different address codes.

Since pseudo-random codes are superimposed when sending signals, the frequency spectrum of the signal is greatly widened.

Therefore, a communication system that uses cdma technology is also called a spread spectrum communication system.

It has a lot of them, such as high spectrum utilization, good voice quality, strong confidentiality, low call drop rate, small electromagnetic radiation, large capacity, wide coverage, etc.

From the perspective of 3g development, cdma is indeed in a leading position.

However, Su Qiuyue knew the rise and fall of various network systems in the future.

The future development of cdma will also encounter some bottlenecks.
