"Actually, what I'm most dissatisfied with about this pager is that it's too small." Fang Chen said slowly.

Small?

Ma Huateng said a little dumbfounded: "Isn't miniaturization what electronic products have always been pursuing?"

The development trend of computers, mobile phones, and even Motorola pagers is to make them smaller and smaller. Why did Mr. Fang do the opposite?

"Great! Both good-looking and righteous!" Fang Chen said categorically, one word at a time.

It is true that general electronic products are getting smaller and smaller, but display-type products, or electronic products related to direct viewing by the eyes, are not the same. They should all be made larger and larger.

The most typical example is that the screens of smartphones are getting bigger and bigger. Even the iPhone, which was originally planning to hold on to the 3.5 screen until death, ended up honestly making the screen bigger and bigger. Later, not only did a plus version come out

, even the 6.5 max version is out.

And you have to know that the screen area of ​​6.5 is three times that of 3.5. In front of a larger screen, the grip feeling is not worth mentioning.

In addition, why do people care so much about folding screens? Isn’t it because they want to have a larger screen without affecting portability?

Fang Chen believes that even if Jobs is still alive, he can only obey this trend. If he still clings to the 3.5 screen, only the iPhone will die. This is how the world will develop.

So being big means good looks and justice!

"For example, if two TVs with sizes of 21 inches and 29 inches are placed in front of you, which one would you choose?"

"It must be twenty-nine inches!" Ma Huateng said without hesitation.

Even a fool knows that watching a big TV is more enjoyable and more comfortable.

"Isn't that enough?" Fang Chen said.

Ma Huateng scratched the back of his head, "But this isn't a TV, and there's nothing interesting to watch."

He probably understood what Fang Chen meant, but pagers are really nothing to look at. Not to mention that the mainstream pagers now are still digital display pagers, which only display a few numbers. Even Motorola's Chinese display pagers,

There is not much content in a message, so it is enough to display eight Chinese characters at one time. Just press the page key twice more.

"Today's pagers do not have any demand for screens and viewing, but if there is no demand, we can create demand!" Fang Chen's eyes flashed with an inexplicable light.

Ma Huateng covered his forehead. He felt that his four years of college were in vain. Why couldn't he understand what Mr. Fang meant?

What is the need for a pager? Wouldn't it be nice to have a pager that lets you know who is looking for you?

"Not to mention the mainstream digital display pagers, let's talk about the Chinese display pagers. Motorola's Chinese display pagers can only display a maximum of twenty characters per message, which only satisfies the user to know who is calling him.

That’s it, but what if each message can display up to seventy characters? Can users get more content from this message?”

"For example, what time do you pick up your children from school, or go to the vegetable market to sell a pound of potatoes when you come back? You can even express your thoughts and love through this message." Fang Chen said slowly.

What he just mentioned is, to put it bluntly, the common text messaging function in everyone’s mobile phones. In 2012, the number of mobile text messages sent nationwide reached 900 billion every year, which greatly changed the impact of mobile phones on people’s lives.

It’s just that after the emergence of WeChat, especially middle-aged people and the elderly all use WeChat, text messages have no choice but to withdraw from the stage of history. After all, everyone is too lazy to use text messages to express New Year greetings. The biggest role of text messages has been reduced to

Receive verification code.

But at this time, text messaging was still a relatively new feature, and it hadn't even appeared in the world yet.

The world's first text message in history appeared in December this year and was sent through the GSM network. GSM is one of the main standards of 2G.

As for why he wanted to enable the SMS function for his pager, it was because the pager was too inconvenient.

Of course, compared to the era before pagers, pagers have indeed greatly satisfied people's need for timely information, but for Fang Chen, a person who has been reborn once, it is really troublesome.

After the pager receives the other party's message, it actually doesn't know why the other party is looking for it. If you want to know, you must immediately find a way to call back.

After all, the role of code is still too limited.

And these days, except for those who have phones in their offices and can connect to the Internet, most people have to run out and find a public phone to return calls.

With the current penetration rate of landline phones, you basically have to travel three to five hundred meters or even further to find a public phone, and there is a high possibility that you will need to queue up.

And the calling party also needs to wait by the phone. As for when the other party will call back, only God knows.

Sometimes it takes half an hour or even longer to get back a call, which is normal.

For Fang Chen, this method is as backward as primitive society, which is why he skipped the pager and bought a mobile phone.

Although Big Brother has problems such as being bulky and having poor signal, you can make calls at any time without waiting, and it is not short of money.

Once you have the text message function, you don’t have to be so troublesome. Some unimportant things, such as what time he said just now, what time to pick up the children, go home to buy groceries, etc., just send a text message, and the other party will know and understand.

After understanding the other party's intention, there is no need to find a way to return the phone in such a troublesome manner.

Even to talk about an extreme thing, the child is sick and the mother asks the father to come over. According to the current way of using pagers, the mother basically needs to wait by the phone for dozens of minutes, enduring the anxiety and anxiety in her heart.

But with text messages, you can directly tell the father what illness the child is suffering from, which hospital he is in, what ward number he is in, and other information, completely eliminating all unnecessary anxiety and waiting.

And he also believed that people needed to use pagers to send more messages, otherwise codes such as those in "Digital Love" would not have been invented.

For example, 3155530 means I miss you, 570 means I am angry with you, and 000 means I want to kiss you.

Ma Huateng was stunned. Fang Chen's words seemed to have opened a new door for him. The pager could still be played like this, but why did he feel that it was a bit fanciful or unreliable?

After carefully thinking about his understanding of wireless paging systems in the past few years, especially his research in the past few months, he felt that Fang Chen's idea was good, but it was unrealistic to implement it.

In other words, it really can't be done with existing technology.

At present, Chinese pager systems generally use manual connection, and the display of Chinese characters relies on each paging receiver to use ROM, that is, a semiconductor memory, to establish a simple Chinese character library inside the pager to achieve the function.

When the system is working, the paging center operator receives user information, then inputs the paging operating system word by word using Wubi font in a concise arrangement, and then sends out paging signals using pocsag encoding.

Then on the user side, that is, on the paging receiver, there are two Chinese display solutions.

One is a code-type Chinese character pager. For example, common phrases are composed of decimal digit codes, such as 254-Mrs., 255-Son, 783-Please get up, etc.

The operator inputs 255,783 into the paging operating system, and after the pager receives the message, it can display a Chinese message like "Son, please get up" on the display screen.

But this solution is a simple solution, which just eliminates the problem of memorizing and carrying the code book.

The second solution is a real Chinese character pager, which uses Chinese characters as the main page and codes as the paving method.

For example, the latest consulting Chinese pager currently being developed by Motorola Huaxia Company contains the standard gb-2312-80 simplified Chinese character library, which can display all commonly used Chinese characters on the pager.

But the problem is that each Chinese character needs to be transmitted in the wireless channel with a size of 14 bits, and an information code word is only 20 bits. In a pocsag encoding method, there are only sixteen information code words at most. In the case of 320 bit, twenty Chinese characters are enough

It occupies fourteen information code words, 280 bits, and finally adds an address code word of the information code word.

Calculated in this way, sending twenty Chinese characters already occupies fifteen information codewords, which is equivalent to the entire pocsag code group.

Therefore, the paging station of the Chinese character pager must limit the paging content, otherwise the number of paging users that each channel can accommodate will be greatly reduced. This is why in the second set of solutions, there are still codes.

"Limited by the pocsag encoding method, I think this is difficult. Do you know what the pocsag code is?" Ma Huateng said euphemistically and uncertainly.

Fang Chen glanced at Ma Huateng. Ma Huateng had only been communicating for a few months and he dared to show off in front of him.

How could he, a person who had been a correspondent for more than 20 years in his previous life, not know the pocsag code? If he were not afraid of scaring Ma Huateng, he would really want to talk to Ma Huateng about what 5G is and open his eyes.

The pocsag code was successfully researched by the British Post Office and recommended by CCIR as the international number 1 for wireless paging in 1978. It is a paging code widely used in many countries.

It is also the coding format used in my country's public wireless paging systems stipulated in the "Wireless Paging Network Technical System" of the Ministry of Posts and Telecommunications of my country. It has the advantages of high coding efficiency, strong error correction ability, and large address capacity.

"I know, then develop a code yourself." Fang Chen looked at Ma Huateng intently and said with great seriousness.

Develop your own code!

Ma Huateng couldn't help but take a breath. He was a little frightened by Fang Chen. The pocsag code was developed by the British Postal Service back then, and it took a lot of effort to develop it.

If nothing else, the power of pocsag code can be seen from the fact that pocsag code is still the international universal wireless paging system encoding format.

It’s not that other countries or companies haven’t developed other encoding formats, but they have all been defeated by POCSAG code.

"Are you kidding?" Ma Huateng said timidly.

Fang Chen nodded heavily, of course he wasn't joking.

The pocsag code is indeed good. When it was first developed in 1976, it could indeed be called unique and second to none, and it greatly solved the problem of information transmission in the wireless paging system.

But it is already 1992. With the rapid development of the paging industry and the sharp increase in users, the system using the pocsag encoding format is no longer practical enough.

Therefore, Motorola developed a new high-speed encoding system flex in 1993, and it was selected as the high-speed wireless paging encoding format for postal and telecommunications in my country in 1996.

With flex, the problems mentioned by Ma Huateng just now are no longer a problem.

What he wants now is for Ma Huateng to develop the flex code that belongs to Qingtian.

At this time, Ma Huateng really didn't know what to say. He felt that Fang Chen's idea was a bit fanciful. Developing the code himself was much more difficult than the 70 words per message Fang Chen said.

For 70 words, he could still think of a way, such as sending 70 words in four messages, but developing the code himself would be really life-threatening.

"Is it difficult?" Fang Chen suddenly asked.

Ma Hua's head was like pounding garlic, and he nodded repeatedly. It was hard to get to his grandma's house.

"But I don't think it's difficult. Although the pocsag code is good, it is a technology from 1976 after all. In the past two decades, the world's communications industry has undergone tremendous changes. Various new research papers and results have emerged one after another. Among them

There must be some good solutions and technologies, all you need is to integrate them and develop a set of feasible coding." Fang Chen said seriously.

After hearing this, Ma Huateng couldn't help but squint his eyes and felt a flash of inspiration in his mind. Although he resisted developing the code by himself, Fang Chen was absolutely right. No matter how powerful the POCSAG code was, it was still a technology from 1976. In technology

In the increasingly innovative modern world, it has long been outdated and backward.

Looking at Ma Huateng's appearance, Fang Chen sat up and said quietly: "You don't want the company and your technology to just imitate and copycat, right?"

Ma Huateng swallowed and said nothing, but he actually felt that there was nothing wrong with copycatting and imitating.

"I know it is quite difficult. It is a huge challenge for you and the company, but as a high-tech company, Qingtian must have its own technology, or unique skills, that can serve China

, contribute to the world. If you can't do it, then I can only say that you are not suitable for Qingtian. Qingtian is destined to be a company of brave people. In terms of pursuing technology and improving China's scientific and technological strength, Qingtian has no regrets!

"Fang Chen stared at Ma Huateng and said word by word.

Fang Chen's words were like a heavy hammer, hitting Ma Huateng's heart hard.

For a moment, Ma Huateng felt as if he had been struck by lightning and didn't know what to say.

Fang Chen turned to look out the window. Anyway, he was unwilling to be an imitator, following others and picking up their leftovers. If this was the case, his rebirth would have been a failure.

And as Taizu said, prosperity cannot rely on introduction, and science has never been a shortcut!
